Rome, Ancient City And Architecture Of
ROME, ANCIENT CITY AND ARCHITECTURE OF The chief building materials used in ancient Rome may be enumerated as follows: (i) Tufa, the " ruber et niger tophus" of Vitruvius (ii. 7), varying in colour from Building warm brown to yellow or greyish green (called matericapellaccio). The Aventine, Palatine and Capitoline a7s< Hills contained quarries of the tufa, much worked at an early period (see Liv. xxvi. 27, xxxix. 44, and Varro, L.L. iv. 151). It is a very bad " weather-stone," but stands well if protected with stucco (Plin. H.N. xxxvi. 166). (2) Lapis Albanus, from Alba Longa, of volcanic origin, a conglomerate of ashes, gravel and fragments of stone; its quarries are still worked at Albano and Marino. This is now called peperino, from the black scoriae, like peppercorns, with which the brown conglomerate mass is studded. (3) Lapis Gabinus, from Gabii, very similar to the last, but harder and a better weather-stone; it contains large lumps of broken lava, products of an earlier eruption, and small pieces of limestone. According to Tacitus (Ann. xv. 43), it is fire-proof, and this is also the case with the Alban stone. Lapis Gabinus is now called sperone. (4) Silex (mod. selce), a lava from the now extinct volcanoes in the Alban Hills, used for paving roads; when broken into small pieces and mixed with lime and pozzolana it formed an immensely durable concrete. It is dark grey, very hard and breaks with a slightly conchoidal fracture (Plin. H.N. xxxvi. 135; Vitr. ii. 7), but does not resemble what is now called silex or flint. (5) Lapis Tiburtinus (travertine), the chief quarries of which are at Tibur (Tivoli) and other places along the river Anio; a hard pure carbonate of lime, of a creamy white colour, deposited from running or dripping water in a highly 1 By the great flight of marble steps up to S. Maria in AraCoeli. .
stratified form, with frequent cavities and fissures lined with crystals. As Vitruvius (ii. 5) says, it is a good weather-stone, but is soon calcined by fire. If laid horizontally it is very strong, but if set on end its crystalline structure is a great source of weakness, and it splits from end to end. Neglect on the part of Roman builders of this important precaution in many cases caused a complete failure in the structure. This was notably the case in the rostra. (6) Pulvis Puteolanus (pozzolana), so called from extensive beds of it at Puteoli a volcanic product, which looks like red sandy earth, and lies in enormous beds under and round the city of Rome. When mixed with lime it forms a very strong hydraulic cement, of equal use in concrete, mortar or undercoats of stucco. It is to this material that the concrete walls of Rome owe their enormous strength and durability, in many cases far exceeding those of the most massive stone masonry. Vitruvius devotes a chapter (bk. ii. ch. 6) to this very important material.
Bricks were either sun-dried (lateres crudi) or kiln-baked (lateres cocti, testae). The remarks of Vitruvius (ii. 3) seem to refer wholly to sun-dried bricks, of which no examples now exist in Rome. It is important to recognize the fact that among the existing ancient buildings of Rome there is no such thing as a brick wall or a brick arch in the true sense of the word; bricks were merely used as a facing to concrete walls and arches and have no constructional importance. 1 Concrete (opus caementicium, Vitr. ii. 4, 6, 8), the most important of all the materials used, is made of rough pieces of stone, or of fragments of marble, brick, etc., averaging from about the size of a man's fist and embedded in cement made of lime and pozzolana forming one solid mass of enormous strength and coherence. Stucco, cement and mortar (tectorium, opus albarium and other names) are of many kinds; the ancient Romans especially excelled in their manufacture. The cement used for lining the channels of aqueducts (opus signinum) was made of lime mixed with pounded brick or potsherds and pozzolana; the same mixture was used for floors under the " nucleus " or finer cement on which the mosaic or marble paving-slabs were bedded, and was called caementum ex testis tunsis. For walls, three or four coats of stucco were used, often as much as 5 in. thick altogether; the lower coats were of lime and pozzolana, the finishing coats of powdered white marble (opus albarium) suitable to receive painting. Even marble buildings were usually coated with a thin layer of this fine white stucco, nearly as hard and durable as the marble itself a practice also employed in the finest buildings of the Greeks probably because it formed a more absorbent ground for coloured decoration; stone columns coated in this way were called " columnae dealbatae " (Cic. In Verr. ii. i, 52 seq.). For the kinds of sand used in mortar and stucco, Vitruvius (ii. 4) mentions sea, pit and river sand, saying that pit sand is to be preferred.
Marble appears to have come into use about the beginning of the 1st century B.C. Its introduction was at first viewed with great Decora- jealousy,' as savouring of Greek luxury. The orator Crassus was the first to use it in his house on the Palatine, materials. bui't about 92 B.C. ; and, though he had only six small columns of Hymettian marble, he was for this luxury nicknamed the " Palatine Venus " by the stern republican M. Brutus (Plin. H.N. xxxvi. 7). The temporary wooden theatre of the aedile M. Aemilius Scaurus, built in 58 B.C., appears to have been the first building in which marble was more largely used ; its 360 columns and the Tower order of its scena were of Greek marble (see Plin. H.N. xxxvi. 5, 50). In a very few years, under the rule of Augustus, marble became very common. 2 Of white statuary majble four principal varieties were used, (i) Marmor Lunense, from Luna, near the modern Carrara (Strabo, v. p. 222), is of many qualities, from the purest creamy white and the finest grain to the coarser sorts disfigured with bluish grey streaks.
1 In less solid constructions than those which have survived until modern times bricks were doubtless used by themselves.
2 The oft-quoted boast of Augustus (Suet. Aug. 29) that he " found Rome of brick and left it of marble " has probably much truth in it, if for " brick " we read " peperino and tufa." In the time of Augustus burnt brick was very little used, the usual wallfacings being opus quadratum of tufa or peperino, and opus reticulatum of tufa only.
(Ex., the eleven Corinthian columns in the Borsa.) (2) Marmor Hymettium, from Mount Hymettus, near Athens, is coarser in grain than the best Luna marble and is usually marked with grey or blue striations (Strabo ix. p. 399). (Ex., the forty-two columns in the nave of S. Maria Maggiore and the columns in S. Pietro in Vincoh.) (3) Marmor Penteltcum, from Mount Pentelicus, also near Athens, is very fine in grain and of a pure white; it was more used for architectural purposes than for statues, though some sculptors preferred it above all others, especially Pheidias and Praxiteles. (Ex., the bust of the young Augustus in the Vatican.) (4) Marmor farium, from the Isle of Paros, is very beautiful, though coarse in texture, having a very crystalline structure. (Ex., the nineteen columns of the round temple in the Forum Boarium.)
Nine chief varieties of coloured marbles were used in Rome. (i) Marmor Numidicum (mod. giallo antico; Plin. H.N. v. 22), from Numidia and Libya, hence also called Libycum, is of a rich yellow, deepening to orange and even pink. Co1 '"! Enormous quantities of it were used.especially for columns, wall-linings and pavements. (Ex., seven columns on the arch of Constantme, taken from the arch of Trajan ; the eighth column is in the Lateran basilica.) (2) Marmor Carystium (mod. cipoltino), from Carystus in Euboea (Strabo x. p. 446), has alternate wavy strata of white and pale green the "undosa Carystos" of Statius (Silv. i. 5, 34). From its well-defined layers like an onion (cipolla) is derived its modern name. (Ex., columns of temple of Antoninus and Faustina.) (3) Marmor Phrygium or Synnadicum (mod. pavonazzetto), from Synnada in Phrygia (Strabo xii. p. 577; Juv. xiv. 307; Tibull. iii. 3, 13), is a slightly translucent marble, with rich purple markings, violet verging on red. It was fabled to be stained with the blood of Atys (Stat. Silv. i. 5, 37). (Ex., twelve fluted columns in S. Lorenzo fuori le Mura, and four columns in the apse of S. Paolo fuori, saved from the ancient nave of the basilica, burnt in 1823.) (4) Marmor lasium (probably the modern porta santa), from lasus, is mottled with large patches of dull red, olive green and white. The " holy doors " of the fbur great basilicas are framed with it, hence its modern name. (Ex., the slabs in front of the hemicycle of the Rostra and four columns in S. Agnese fuori le Mura). (5) Marmor Chium (probably the modern Africano), from Chios, is similar in the variety of its markings to the portasanla, but more brilliant in tint. (Ex., a great part of the paving of the Basilica Julia and two large columns in the centre of the facade of St Peter's.) (6) Marmor Taenarium (mod. rosso antico), from Taenarum in Laconia (Strabo viii. p. 367; Pliny, H.N: xxxvi. 158), is a very close-grained marble, of a rich deep red, like blood. As a rule it does not occur in large pieces, but was much used for small cornices and other mouldings in interiors of buildings. Its quarries in Greece are still worked. (The largest pieces known are the fourteen steps to the high altar of S. Prassede and two columns nearly 12 ft. high in the Rospigliosi Casino dell' Aurora.) (7) The name Marmor Taenarium is also applied by the ancients to a black marble (nerp antico) now no longer quarried. It is mentioned by Tibullus (iii. 3, 14) in conjunction with Phrygian and Carystian marbles; see also Prop. iii. 2, 9, and Plin. H.N. xxxvi. 135. (Ex., two columns in the choir of S. Giovanni in Laterano.) (8) Lapis Atracius (verde antico), found at Atrax in Thessaly, was one of the favourite materials for decorative architecture; it is not strictly a marble (i.e. a calcareous stone) but a variety of " precious serpentine," with patches of white and brown on a brilliant green ground. It seldom occurs in large masses. (The finest known specimens are the twenty-four columns beside the niches in the nave of the Lateran basilica.) (9) The hard oriental alabaster, the " Onyx " or " alabastrites " of Pliny (H.N. xxxvi. 59, xxxvii. 109) ; its chief quarries were on the Nile near Thebes,* in Arabia and near Damascus. In Pliny's age it was a great rarity; but in later times it was introduced in large quantities, and fragments of a great many columns have been found on the Palatine, in the baths' of Caracalla and elsewhere. It is semi-transparent and beautifully marked with concentric nodules and wavy strata. An immense number of other less common marbles have been found, including many varieties of breccia, whose ancient names are unknown. 4 From the latter part of the 1st century B.C. hard stones granites and basalts were introduced in great quantities. The basalts " basanites " of Pliny (xxxvi. 58) are very refractory, and __ can only be worked by the help of emery or diamond dust. /r * n "< The former was obtained largely at Naxos; diamonddust drills are mentioned by Pliny (H.N. xxxvii. 200). The basalts are black, green and brown, and are usually free from spots or markings; examples of all three exist, but are comparatively rare. The red variety called " porphyry " was used in enormous quantities. It is the " porphyntes " of PHny (H.N.
* These Nile quarries were worked during the 19th century, and many blocks were imported into Rome for the rebuilding of S. Paolo fuori le Mura.

5 86 ROME xxxvi. 57), and was brought from Egypt. It has a rich red ground, covered with small specks of white felspar; hence it was also called " leptopsephos." A large number of columns of it exist, and it was much used for pavements of opus Alexandrinum. A rich green porphyry or basalt was also largely used, but not in such great masses as the red porphyry. It has a brilliant green ground covered with rectangular light green crystals of felspar. This is the lapis Lacedaemonius (wrongly called by the modern Romans " scrpentino "), so named from its quarries in Mount Ta^getus in Lacedaemonia (Paus. iii. 21, 4; Plin. H.N. xxxvi. 55; Juv. xi. 175). It appears to have been mostly used for pavements and panels of wall linings. The granites used in Rome came mostly from near Philae on the Nile (Plin. H.N. xxxvi. 63). The red sort was called lapis pyrrhopoecilus and the grey lapis psaronius. The columns in the Basilica Ulpia are a fine example of the latter; both sorts are used for the columns of the Pantheon and those of the temple of Saturn in the Forum. Gigantic ships were specially made to carry the obelisks and other great monoliths (Plin. H.N. xxxvi. 2, 67).
The style of architecture employed in ancient Rome (see ARCHITECTURE, section Roman, and ROMAN ART) may be Anhi- sa id to have passed through three stages the iectunt Etruscan, the Greek and the Roman. During the styles. fi rs t f ew centuries of the existence of the city, both the methods of construction and the designs employed appear to have been purely Etruscan. The earliest temples were either simple cellae without columns, or else, in the case of the grander temples, such as that of Capitoline Jupiter, the columns were very widely spaced (araeostyle), and consequently had entablatures of wooden beams. The architectural decorations were more generally in gilt bronze or painted terra-cotta than in stone, and the paintings or statues which decorated the buildings were usually the work of Etruscan artists. 1 The Greek influence is more obvious; it is found in the period following the Second Punic or Hannibalic War, and almost all the temples of the earlier imperial age are Greek, with certain modifications, not only in general design but in details and ornaments. Greek architects were largely employed, such as Apollodorus of Damascus, who designed Trajan's forum and other buildings; on the other hand, a Roman, Cossutius, was employed on the building of the Olympieum at Athens, in the and century B.C. Roman architects such as Vitruvius and C. Mucius in the 1st century B.C., Severus and Celer under Nero, and Rabirius under Domitian, were Greek by education, and probably studied at Athens (see Vitr. vii. Praef.; Hirt, Gesch. d. Baukunst, ii. p. 257).* The Romans, however, though far below the Greeks in artistic originality, were very able engineers, and this led to the development of a new and more purely Roman style, in which the restrictions imposed by the use of the stone lintel were put aside and large spaces were covered with vaults and domes cast in semi-fluid concrete, a method which had the enormous advantage of giving the arched form without the constant thrust at the springing which makes true arches or vaults of wide span so difficult to deal with. The enormous vaults of the great thermae, the basilica of Constantine, and the like, cover their spaces with one solid mass like a metal lid, giving the form but not the principle of the arch, and thus allowing the vault to be set on walls which would at once have been thrust apart had they been subjected to the immense leverage which a true arched vault constantly exerts on its imposts." This is a very important point, and one which is usually overlooked, mainly owing to the Roman practice of facing their concrete with bricks, which (from an examination 1 Pliny (H.N. xxxv. 154), quoting Varro, says that the decorations in painting and sculpture of the temple of Ceres near the Circus Maximus were the work of the first Greek artists employed in Rome, and that before that (c. 493 B.C.) " all things in temples were Etruscan." Vitruvius (iii. 3) says, " Ornantque signis fictilibus aut aereia inauratis eorum fastigia Tuscanico more, uti est ad Circum Maximum Cereris, et Herculis Pompeiani, item Capitolii " (cf. iv. 7, vi. 3).
1 The frequent use of engaged columns is a peculiarity of Roman architecture, but it is not without precedent in Greek buildings of the best period, e.g. in the temple of Zeus at Agrigentum. Surface enrichments over the mouldings were used far more largely by the Romans than by the Greeks.
1 In the beautiful drawings of Choisy (L'Art de bdtir chez les Remains, Paris, 1873) the structural importance of the brick used in vaults and arches is very much exaggerated.
of the surface only) appear to be a principal item in the construction. The walls of the Pantheon, for example, are covered with tiers of brick arches, and many theories have been invented as to their use in distributing the weight of the walls. But a recognition of the fact that these walls are of concrete about 20 ft. thick, while the brick facing averages scarcely 6 in. in thickness, clearly shows that these " relieving arches " have no more constructional use as far as concerns the pressure than if they were painted on the surface of the walls. The same applies to the superficial use of brick in all arches and vaults. Although, however, the setting of the concrete rendered the brick facing superfluous, it played its part in sustaining the fluid mass on its centring during the process of solidification.
At first tufa only was used in opus quadratum, as we see in the so-called wall of Romulus. Next the harder peperino began to be worked: it is used, though sparingly, in the " Servian " wall, and during the later Republic appears to have been largely employed for exterior walls or points where there was heavy pressure, while other parts were built of tuia. Thirdly, travertine appears to have been introduced about the 2nd century B.C. but was used at first for mereiy ornamental purposes, very much as marble was under the Empire; after about the middle of the 1st century A.D. travertine began to be largely used for the solid mass of walls, as in the temple of Vespasian and the Colosseum. The tufa or peperino blocks were roughly 2 (Roman) ft. thick in regular courses (the ' isodomum " of Vitruvius) by 2 ft. across the end, and under the Republic often exactly 4 ft. long, so that two blocks set endways ranged with one set lengthways. They were arranged in alternate courses of headers and stretchers, so as to make a good bond; this is the " emplecton " of Vitruvius (ii. 8). The so-called Tabularium of the Capitol is a good example of this. The harder and more valuable travertine was not cut in this regular way, but pieces of all sizes were used, just as they happened to come from the quarry, in order to avoid waste : blocks as much as 15 by 8 ft. were used, and the courses varied in thickness t h e " pseudisodomum " of Vitruvius. When tufa or peperino travertine, it was cut so as to range with the irregular courses of the latter.
It is interesting to note the manner in which the Roman builders mixed their different materials according to the weight they had to carry. While tufa was frequently used for the main walls, peperino (e.g. in the 1 Servian " wall on the Aventine) or^ travertine (e.g. in* the forum of Augustus and the temple of Fortuna :G. i.

FIG. 7. PLAN OF ANCIENT ROME.
The use of mortar with opus quadratum is a sign of a comparatively early date. It occurs, e.g. in the " Servian " wall on the Aventine .. and in the Tabularium. Under the Empire massive blocks, whether of tufa, travertine or marble, are set without any mortar. It must, however, be observed that in these early instances the " mortar " is but a thin stratum of lime, little thicker than stout paper, used not as a cement to bind the blocks together, but simply damns to g ' ve e J' nts a smoothly fitting surface. The actual binding together was done by clamps and dowels, as well as by the mass and weight of the great blocks used. Except in the earliest masonry, each block was very carefully fastened, not only to the next blocks on the same course, which was done with double dove-tailed dowels of wood, but also to those above and below with stout iron clamps, run with lead (Vitr. ii. 8). 1 In more ornamental marble work bronze clamps were often used. Concrete is rarely found in connexion with opus quadratum; part of the " Servian wall on the Aventine received a backing of concrete at a relatively late period Up to the 1st century B.C it was faced with opus incertum small irregularly shaped blocks of tufa, 3 to 6 in. across, with pointed ends driven into the concrete while it was soft, and worked smooth on the face only (see fig. 2). From the beginning of the 1st century B.C. opus reticulatum? formed of rectangular tufa prisms laid in a regular pattern like a net (whence the name), is found. It is very neat in appearance, and is often fitted with great care,though it was generally covered with stucco. The so-called " house of Livia " on the Palatine is a good exampleof the earlier sort, when the quoins were made of small rectangular blocks of tufa. Under the Empire brick quoins came into use (as may be seen, e.g. in the so-called palace of Caligula). Though in Rome opus reticulatum was ajmost always made of tufa, in the neighbourhood of the city it was sometimes of peperino or even lava, where these materials were found on the spot.
FIG. 2. Concrete Wall FIG. 3. Section of Concrete Wall, showfaced with (A) Opus In- ing the use of bricks merely as a certumand(B)OpusRe- facing, ticulatum. C shows the section, similar in both.
Of concrete walls faced with burnt bricks no dated example earlier than the middle of the 1st century B.C. is known. The facing consisted at first of triangular fragments of tiles (teguloe), broken for the purpose and more or less irregular in shape facing. anc j s j ze> k ut f rom t h e latter part of the 1st century A.D. onwards triangular bricks were specially manufactured for wallfacings. This shape was adopted in order to present a large surface on the face with little expenditure of brick, and also to improve the bond wrth the concrete behind (see fig. 4). Even party walls of small rooms are not built solid, but have a concrete core faced with brick triangles about 3 in. long. In order to support the facing until the concrete was set, the Roman builders used a wooden framing covered with planks on the inside. Sometimes the planks were nailed outside the wooden uprights, as was done with unfaced concrete walls, and then a series of grooves appear in the face of the brickwork. Walls faced with opus reticulatum must have been supported temporarily in the same way.
The character of the brick facing is a great help towards determining the date of Roman buildings. In early work the bricks are thick and the joints thin, while in later times the reverse is the case, so that brickwork of the time of Severus and later has more bricks to the foot than that of the Flavian period.
The length of the bricks as it appears on the face is no guide to the date, since one or more of the sharp points of the brick triangles were frequently broken off before they were used. Moreover, 1 The expansion of the iron through rust, which caused the stone to split, has frequently been a great source of injury to Roman walls, as well as the practice, common in the middle ages, of breaking into the stones in order to extract the metal.
1 These two kinds of stone facings are mentioned thus by Vitruvius (ii. 8), " reticulatum, quo nunc [reign of Augustus] omnes utuntur, et antiquum, quod incertum dicitur."
varieties both in quality of workmanship and size of the bricks often occur in work of the same date. In the remains of Nero's Golden House great varieties appear, and some of the walls in the inferior rooms are faced with very irregular and careless brickwork. 1 Special care and neatness were employed in the rare cases when the wall was not to be covered with stucco, which in the absence of marble was usually spread over both inside and outside walls. All these circumstances make great caution necessary in judging of dates; fortunately after the 1st century A.D., and in some cases even earlier, stamps impressed on bricks, and especially on the large tiles used for arches, give clearer indications. The reason of the almost universal use of smooth facings either of opus reticulatum or of brick over concrete walls is a very puzzling question; for concrete itself forms an excellent ground for the stucco coating or backing to the marble slabs, while the stucco adheres with difficulty to a smooth facing, and is very liable to fall away. The modern practice of raking out the joints to form a key was not employed by the Romans, but before the mortar was hard they studded the face of the wall with marble plugs and iron or bronze nails driven into the joints, so as to give a hold for the stucco a great waste both of labour and material. 4 The quality of the mortar varies according to its date: during the ist and 2nd centuries it is of remarkable hardness made of lime with a mixture of coarse pozzolana of a bright red colour; in the 3rd century *t began to be inferior in quality; and the pozzolana used under the later Empire is brown instead 01 red. _ Concrete was at first always made of lumps of tufa; then travertine, lava, broken bricks and even marble were used, in fact all the chips and fragments of the mason's yard. Under concrete the Empire the concrete used was made with travertine walls aod or lava for foundations, with tufa or broken bricks for vau u s , walls, and with tufa or pumice-stone (for the sake of lightness) for vaults. Massive walls were cast in a mould ; upright timbers, about 6 by 7 in. thick and 10 to 14 ft. long, were set in rows on each face of the future wall; planks 9 to lo in. wide were nailed to them, so as to form a case, into which the semifluid mass of stones, lime and pozzolana was poured. When this was set the timbers were removed and refixed on the top of the concrete wall; then fresh concrete was poured in; and this process was repeated till the wall was raised to the required height. Usually such cast-work was only used for foundations and cella walls, the upper parts being faced with brick; but in some cases the whole wall to the top was cast in this way and the brick facing omitted. In strength and durability no masonry, however hard the stone or large the blocks, could ever equal these walls of concrete when made with hard lava or travertine, for each wall was one perfectly coherent mass, and could only be destroyed by a laborious process like that of FIG. 4. Example of Marble Lining, from the Cella of the Temple of Concord. A. Slabs of Phrygian marble. B. Plinth moulding of Numidian "giallo." C. Slab of cipollino (Cary st ' an marble). D.

quarrying hard stone from its native bed. Owing to this method of building the progress of the work from day to day can often be traced by a change in the look of the concrete. About 3 ft. appears to have been the average amount of wall raised in a day.
Marble linings were fixed very firmly to the walls with long clamps of metal, hooked at the end so as to hold in a hole made in the marble slab. Fig. 4 gives an example, of the time of Marble Augustus, fixed against a stone wall. The blocks were usually marked in the quarry with a number, and often tf& with the names of the reigning emperor and the overseer of the quarry. These quarry-marks are often of great value as indications of the date of a building or statue.' Metropolitan 'Some of the bricks are as much as 2j in. thick, while ij in. is the usual maximum for Roman bricks.
4 The Roman method of applying stucco to walls with a wooden " float " exactly as is done now, is shown in a painting from Pompeii (see Ann. Inst., 1881, pi. H.).
'See Bruzza, in Ann. Inst. (1870), pp. 106-204; Hirschfeld, Die kaiserlichen Verwaltungsbeamten (1905), pp. 162 ff.
building acts, not unlike those of modern London, were enacted by several of the emperors. These fixed the materials to be used, thickness of walls, minimum width of streets, maximum height allowed for houses, etc. After the great fire in Nero's reign, A.D. 64, an act was passed requiring the lower storeys of houses to be built with fire-proof materials, such as peperino or burnt brick.
Enormous accumulations of statues and pictures enriched Rome during its period of greatest splendour. In the first place, the numerous statues of the republican and even of the regal Ancient period were religiously preserved at a time when, from works of their archaic character, they must have been regarded rather as objects of sacred or archaeological interest than as works of art (Plin. H.N. xxxiv. 15 ff., xxxv. 19 ff.). Secondly came the large Graeco-Roman class, mostly copies of earlier Greek works, executed in Rome by Greek artists. To this class belongs most of the finest existing sculpture preserved in the Vatican and other museums. Thirdly, countless statues and pictures were stolen from almost every important city in Greece, Magna Graecia, Sicily and western Asia Minor. These robberies began early, and were carried on for many centuries. The importations included works of art by all the chief artists from the Jth century downwards. Long lists are given by Pliny (H.N. xxxiii.-xxxvi.), and pedestals exist with the names of Praxiteles, Timarchus, PolycHtus, Bryaxis and others. These accumulated works of sculpture* were of all materials gold and ivory (Suet. Tit. 2), of which seventy-four are mentioned in the catalogue of the Breviarium, many hundreds or even thousands of silver 1 (Plin. H.N. xxxiii. 151 f.), while those of gilt bronze and marble must have existed in almost untold numbers (Paus. viii. 46). Nor were the accumulated stores of Greek paintings much inferior in number; not only were easel pictures by Zeuxis, Apelles, Timanthes and other Greek artists taken, but even mural paintings were carefully cut off their walls and brought to Rome secured in wooden frames (Plin. H.N. xxxv. 173, and compare ibid. 154).
The roads were made of polygonal blocks of lava (silex), neatly fitted together and laid on a carefully prepared bed, similar to that used for mosaic paving (see MOSAIC and ROADS). Roads thus made were called viae stralae. A good specimen of Roman road-making, in which the blocks were fitted together with the utmost accuracy, is to be seen in a portion of the Clivus Capitolinus in front of the temple of Saturn (see fig. 5, which also shows the massive travertine curb which bordered the road; sometimes the curb was of lava). In 1901 the late and badly laid pavement of the Sacra Via on the ascent of the Velia was removed, and the earlier paving laid bare at a lower level.

Remains of Prehistoric Rome.
It is evident from recent discoveries that the site of Rome was inhabited at a very early period. 2 Flint implements and remains of the Bronze Age have been found on the Aventine and elsewhere; and from the Early Iron Age onwards we have a continuous archaeological record, owing to the discovery of ancient burial-places. In 1902 a very early necropolis was brought to light at the S.E. corner of the temple of Antoninus and Faustina, some 17 ft. below the level of the Forum. The graves contain either the ashes of cremated bodies placed in a large vessel (dolio), or skeletons buried either in a simple trench (fossa), a tufa sarcophagus or a tree-trunk. The cremation graves are the earlier, and none are later than the 6th century, while the oldest may be of the 9th; the pottery and other objects placed in the graves belong to the Early Iron Age. It is clear that this cemetery is earlier than the union of the Palatine and Quirinal settlements in one city (see below, p. 759). Other early cemeteries have been discovered on the Quirinal and Esquiline, which were in use from the beginning of the Iron Age down to the beginning of the historic period. The large necropolis on the Esquiline is cut in two by the " Servian " wall, which is evidently of later date. The later tombs contain objects of Etruscan, Phoenician and Greek manufacture.
There is no doubt that the earliest settlement bearing the name of Rome was on the Palatine hill, 3 which was both easy of defence and possessed the means of communica- The tion with its neighbours in the proximity of the Palatine Tiber. The name Roma is said to mean " river," cltybut this is uncertain. The Palatine is roughly square in outline, and the Roman antiquarians sometimes applied the name Roma Quadrata to the earliest settlement; but the term seems more properly to have applied to a sanctuary connected with the foundation of the city. The ideal boundary of the city was formed by the Pomerium (see Varro, L.L. v. 143; Liv. i. 44; Dionys. i. 88), whose original course is traced by Tacitus (Ann. xii. 24). It passed along the foot of the hill (per ima mantis Palatini), the angle-points being given by the Ara Maxima in the Forum Boarium, the Ara Consi in the Circus Maximus, the Curiae Veteres (near the arch of Constantine) and the Sacellum Larum (at the N. angle). But this was of course not a defensible site, and the extent of the fortified city can only be determined by the traces of its early walls. These enable us to fix its line along the whole valley of the Velabrum, on the west of the hill, and along the valley of the Circus Maximus as far as the so-called Paedagogium, about half-way on the south side.
Considerable remains of this fortification exist near the west angle of the hill. These show that the natural strength given by the cliff was increased by artificial means. The wall was set neither at the top nor at the foot of the hill, but more Anckat than half-way up, a level terrace or shelf all round being fortlf/- cut in the rock on which the base of the wall stood. Above <*tlons. that the hill was cut away into a cliff, not quite perpendicular but slightly " battering " inwards, to give greater stability to the wall, which was built up against it, like a retaining wall, reaching to the top of the cliff, and probably a few feet higher. The stones used in this wall are soft tufa, a warm brown in colour, and full of masses of charred wood. The cutting to form the steep cliff probably supplied part of the material for the wall; and ancient quarries, afterwards used as reservoirs for water, exist in the mass of rock on which the so-called temple of Jupiter Victor stands. It has been asserted that these tufa blocks are not cut but split with wedges; this, however, is not the case. Tufa does not split into rectangular masses, but 2 On the prehistoric^ remains of Rome and Latium, see Pinza in Monumenti antichi pubblicati per euro delta reale Accademia dei Lincei, vol. xv., 1905; also Comm. Boni's reports on the necropolis adjoining the Forum in the Notizie degli scavi, and Modestor, Introduction d I'histoire romaine (Paris, 1907).
3 The " primacy of the Palatine " has been disputed by Carter (Amer. Jour. Arch., 1908, p. 181), who thinks that the first city was that of the Four Regions (see below) formed by the Etruscan kings.
would be shattered to pieces by a wedge; moreover, distinct tool-marks can be seen on all the blocks whose surface is well preserved and in the quarries themselves. Chisels from one-fourth to three-fourths of an inch in width were used, and also a sharp-pointed pick or hammer. The wall is about 10 ft. thick at the bottom, and increases in thickness above as the scarped cliff against which it is built recedes. It is built of blocks laid in alternate courses of headers and stretchers, varying in thickness from 22 to 24 in., in length from 3 to 5 ft. and in width from 19 to 22 in. These blocks are carefully worked on their beds, but the face is left rough, and the vertical joints are in some cases open, spaces of nearly 2 in. being left between block and block; in other cases the vertical joints are worked true and close like the beds. No mortar was used. At two points on the side of the Velabrum winding passages are excavated in the tufa cliff, the entrance to which was once closed by the ancient wall. One of these in early times (before water in abundance was brought to the Palatine on aqueducts) was used as a reservoir to collect surface water, probably for use in case of siege ; circular shafts for buckets are cut downwards through the rock from the top of the hill. A similar rock-cut cistern with vertical shafts, of very early date, exists at Alba Longa. Opposite the church of S. Teodoro a series of buttresses belonging to the early wall exists, partly concealed by a long line of buildings of the later years of the Republic and the early Empire, to make room for which the greater part of the then useless wall was pulled down, and only fragments left here and there, where they could be worked into the walls of the later houses.
The age of the walls here described cannot be determined with certainty, but their resemblance to the remains of the " Servian " wall, especially in the system of " headers and stretchers " and the dimensions of the blocks, makes it certain that they do not differ greatly in date from that work. The chief technical difference lies in the open vertical joints found in some cases; but too much stress should not be laid on this feature. There are, however, at the western angle of the hill some remains of an earlier fortification, constructed with blocks of grey-green tufa, smaller in size than those of the main wall. A few courses have been preserved, owing to the fact that at the angle of the hill this wall was encased first of all by that described above and afterwards by concrete substructures of imperial date. The technique is primitive, as the blocks are of irregular size and are not laid in courses of " headers and stretchers " ; the nearest parallel is supplied by the foundations of the temple of Jupiter Capitolinus. These remains are shown by Delbriick, Der Apollotempel auf dem Marsfelde, pi. iii., cf. p. 13 f.
Pliny (H.N. iii. 66) tells us that the city of Romulus had three gates (cf. Serv. Ad. Aen. i. 222); and three approaches to the . Palatine city can be traced. One is the so-called Scalae Caci, a long sloping ascent cut through the rock (see '"*? . fig. 17) from the side of the Circus Maximus; some vua ' remains of the early wall still exist along the sides of this steep ascent or staircase. The upper part of this has remains of a basalt pavement, added in later times, probably covering the more ancient rock-cut steps. The name of the gate which led at this point into the Palatine city is unknown. The only two gates whose name and position can be (with any degree of probability) identified are the Porta Romanula and the Porta Mugonia. The former of these is called Porta Romana by Festus (ed. Miilfer, p. 262), who states that it was at the foot of the Clivus Victoriae (see fig. 17) and was so called by the Sabines of the Capitol because it was their natural entrance to Roma Quadrata (see also Varro, L.L. v. 164 (who only mentions the two gates named above), vi. 24). It would thus have been at the foot of the hill in the Velabrum (see below, p. 600); but Varro says that it was approached by steps from the Nova Via, l which would place it at the N. angle of the Palatine. The stairs connecting the Nova Via with the Clivus Victoriae still exist. Doubtful traces of the Porta Mugonia (see Sol. i. 24) have been discovered where a basalt paved road leads up into the Palatine from the Summa Sacra Via and the Summa Nova Via, which join near the arch of Titus; exposure to weather has now destroyed the soft tufa blocks of which this gate was built. This is probably the " vetus porta Palatii " of Liyy (i. 12), through which the Romans fled when defeated by the Sabines.
The Palatine settlement was the nucleus around which, by a series of expansions, the historical city of Rome grew up. The first step nrn ih was tne ama 'g ama t' on f Roma Quadrata with the villages f on the neighbouring spurs of the Esquiline and Caelian.
or early -phis gave birth to the community of the Seven Hills, whose "*'" existence is proved by the survival of the festival known as the Septimontium, celebrated on the nth of December (Fest. 340; Macrob. i. 16, 6). The seven hills were not those familiar in later nomenclature, but the following: (i) Palatium and (2) Cermalus, the two summits of the Palatine; (3) Velia, the saddle between the Palatine and Esquiline; (4) Oppius and (5) Cispius, the two westernmost spurs of the Esquiline, together with (6) Fagutal, the extreme crest of the Oppius; (7) Sucusa (confused by later writers with Subura), the eastern spur of the Caelian. Varro (L.L. v. 48) mentions the murus terreus Carinarum, which may have belonged 1 " Novalia," MSS. " Navalia " has been conjectured.
to the defences of this community, since the N.W. slope of the Oppius bore the name Carinae; but there is no proof that the Septimontium was a walled city.
The next stage in the development of Rome was marked by the division of the city into four regions, ascribed by tradition to Servius Tullius, 1 who was said to have formed the four city tribes, corresponding with the regions: (i) Suburana, including the Caelian and the valley between that hill and the Esquiline; (2) Esquilina, the Oppius and Cispius; (3) Collina, the Quirinal and Viminal; (4) 1 'al.it in. i, including the Palatine and Velia. The third region was an addition to the City of the Seven Hills; the new city was, in fact, formed by the union of the old Latin settlement with a Sabine community on the Quirinal. The Capitol was the citadel, but was not included in the city (hence the phrase urbs et Capitolium).
Tradition likewise assigned to Servius Tullius' the construction of the great wall which embraced not merely the four regions but a considerably extended area, including the Aventine. Excavations have done much to determine the line of the tl"*/ Servian wall, especially the great works undertaken in laying out a new quarter of the city on the Quirinal, Esquiline and Viminal, which have laid bare and then mostly destroyed long lines of wall, especially along the agger. Beginning from the Tiber, which the Servian wall touched at a point near the present Ponte Rotto, and separating the Forum Holitorium (outside) from the Forum Boarium (inside), it ran in a straight line to the Capitoline hill, the two crests of which, the Capitolium and the Arx, with the intermediate valley the Asylum, were surrounded by an earlier fortification, set (Dionys. ix. 68) M X&Jwtt . . . nal -ri-rpaa dirorA^oif. In this space there were two gates, the Porta Flumentana, next the river (see Cic. Ad Alt. vii. 3; Liv. xxxv. 19, 21); and the Porta Carmentalis close to the Capitolium. 4 From the Capitoline hill the wall passed to the Quirinal along a spur of elevated ground, afterwards completely cut away by Trajan. Close to the Capitol was the Porta Fontinalis, whence issued the Via Lata. Remains of the wall and foundations of the gate exist in Via di Marforio. After passing Trajan's forum, we find remains of the walls en the slope of the Quirinal. A piece of the wall has been exposed in the new Via Nazionale, and also an archway under the Palazzo Antonelli, which may represent the Porta Sanqualis (see Festus, ed. Miiller, p. 343). The Porta Salutaris (Festus, pp. 326-327) was also on the Quirinal, probably on the slope between the Trevi fountain and the royal palace. Its position is indicated by the existence of some tombs which give the line of the road. On the north-west of the Quirinal was the Porta Quirinalis (Festus, p. 254), probably near the " Quattro Fontane." In the Barberini palace gardens, and especially in those of the Villa Barberini (Horti Sallustiani), extensive remains of the wall have been recently exposed and destroyed, which was also the fate of that fine piece of wall that passed under the new office of finance, with the Porta Collina, which was not on the line of the present road, but about 50 yds. to the south (see Dionys. ix. 68; Strabo iv. p. 234). Thus far in its course from the Capitol the wall skirted the slopes of hills, which were once much more abrupt than they are now; but from the Porta Collina to the Porta Esquilina it crossed a large tract of level ground; and here its place was taken by the great agger described below. About the middle of it the Porta Viminalis was found in 1872; it stood, as Strabo (iv. p. 234) says, 6ird utaif r<f x<i/aaTi, and from it led a road which passed through the Porta Chiusa (ancient name unknown) in Aurelian's wall. Foundations of the Porta Esquilina were found in 1875 close behind the arch of Gallienus. The further course of the wall across the valley of the Colosseum is the least known part of the circuit. Hence the wall skirts the slopes of the Caelian (where, as is probable, it was pierced by the Porta Caelemontana and Porta Querquetulana) to the valley along which the Via Appia passed through the Porta Capena, near the church of S. Gregorio. Its line along the Aventine is fairly distinct, and near S. Balbina and in the Vigna Torlonia are two of the best-preserved pieces (see below). There were three gates on the Aventine, the Porta Naevia on the southern height, P. Raudusculana in the central depression, and P. Lavernalis on the northern summit. Under the Aventine it appears to have touched the river near the existing foundations supposed to be those of the Pons Sublicius. The Porta Trigemina was close by the bank. Hence to our starting-point the river formed the defence of the city, with its massive quay wall.
The wall is built of blocks of tufa, usually the softer kinds, but varying according to its position, as in most cases the stone used was that quarried on the spot. In restorations a good deal of peperino is used. The blocks average from 23 to fniai'a 24 in. in thickness roughly 2 Roman feet and are ' laid in alternate courses of headers and stretchers. The method of construction varied according to the nature of the ground s Varro, L.L. v. 46-54.
3 Livy i. 44; Dion. Hal. iv. 13. The wall is, however, said to have been planned and partly executed by Tarquinius Priscus (Liv. i. 36, 38; Dion. Hal. iii. 37); and the fortification of the Aventine is ascribed to Ancus Mart ins (Dion. Hal. iii. 43).
4 See Sol. i. 13 ; Liv. ii. 49, xxiv. 47, xxv. 7. xxvii. 37 ; Ascon. Ad. Cic. in Toga, p. 81.
traversed by the fortification. Where the wall followed the face 01 the cliffs, as for instance on the Capitol and Quirinal, it was raisec on an artificial shelf after the fashion employed on the Palatine (vide supra). In other places, where the slope was gentler, the wal was formed of rubble with revetments of opus quadratum, e.g. on the Aventine; finally, where the ground was flat, as on the plateau of the Esquiline, a ditch was dug and an embankment formed by the upcast; this agger, as it was called, was then faced with retaining walls of opus quadratum. The length of the agger on the Esquiline is put by Dionysius (ix. 68) at 7 stadia, which agrees, roughly speaking, with the discoveries made in 1876-1879, when the railway station was built and the new quarters laid out. The total length was about 4225 ft., the thickness of wall and agger about so It., while the ditch was 100 Roman ft. in width and 30 in depth. There is, however, a difference in technique between the inner and outer retaining walls of the agger. The inner wall is built of greenish tufa in blocks of irregular size, while in the outer brown tufa is employed and the blocks are of standard size, two headers ranging with each stretcher. Between the railway station and the Dogana a fine lofty piece of the front wall remains, with traces of the Porta Viminalis ai^d of the lower back wall. Unfortunately the whole of the bank or agger proper has been removed, and the rough back of the great retaining wall exposed. Both tufa and peperino are used, the latter in restored parts; the blocks vary in length, but average in depth the usual 2 Roman ft. The railway cutting, which has destroyed a great part of the agger, showed clearly the section ot the whole work : the strata of different kinds of soil which appeared on the sides of the foss appeared again in the agger, but reversed as they naturally would be in the process of digging out and heaping up. Dionysius (ix. 68) states the length of the agger to have been 7 stadia that is, about 1400 yds. which agrees (roughly speaking) with the actual discoveries. Originally one road ran along the bottom of the foss and another along its edge ; the latter existed in imperial times. But the whole foss appears to have been filled up, probably in the time of Augustus, and afterwards built upon; houses of mixed brick and opus reticulatum still exist against the outside of the great wall, which was itself used as the back wall of these houses, so that we now see painted stucco of the time of Hadrian covering parts of the wall of the kings. Another row of houses seems to have faced the road mentioned above as running along the upper edge cf the foss, thus forming a long street. As early as the time of Augustus a very large part of the wall of the kings had been pulled down and built over, so that even then its circuit was difficult to trace (Dionys. iv. 13). A very curious series Masons' ^ masons ' mar ks exists on stones of the agger wall (as well as on those of some other early buildings). They are deeply incised, usually on the ends of the blocks, and average from 10 to 14 in. in length: some are single letters or monograms; others are numbers, e.g. J, , the numeral 50. Fig. 6 shows the chief forms from the Palatine and Esquiline. 1 There are also extensive remains of the " Servian " wall on the Aventine, in the Via di Porta S. Paolo. Here the wall has a backing of concrete and the upper portion is built with blocks of peperino, set in FIG. 6. Masons' Marks on Early Walls. mort , ar * nd bevelled . at the edges. These are unmistakable signs that the wall has undergone restoration. This portion is pierced by an arch about' 9} ft. high, which probably served as an embrasure for a military engine. Finally, where the wall skirts the bank of the Tiber it is built in two sections a foundation about 2 metres in height and 3 in width, which forms a landing-stage, and an upper wall, 6 metres high, which retains the bank. It is built of peperino, and is probably later than the rest of the fortification.
The age of this wall is uncertain, but it has been rendered exceedingly probable that it belongs to the 4th century B.C. The evidence tor this is derived from the comparison of other fortifications in central Italy, from the measurements of the blocks employed which presuppose the later Roman foot of 296 millimetres, and from tire character of the alphabet from which the masons' marks are taken. 2 Livy (vi. 32) speaks of a contract entered into by the censors of 378 B.C. for the construction of a wall of opus quadratum and this probably refers to the older portions of the existing wall which was built owing to the fear of a second Gallic invasion. 3 /See Bruzza, Ann. Inst. (1876), 72; Jordan, Topographie. i. 250; Richter, Uber antike Steinmetzzeichen (1885).

1 For earlier studies of the Servian wall consult Nibby and Cell, Le The Servian city did not include what is now the most crowded part of Rome, and which under the Empire was the most architecturally magnificent, namely, the Campus Martius, which was probably to a great extent a marsh. It was once called Ager Tarquiniorum, but alter the expulsion of the Tarquins was named Campus Martius from an altar to Mars, dating from prehistoric times (Liv. ii. 5).
Of that wonderful system of massive arched sewers 4 by which, as Dionysius (iii. 68) says, every street of Rome was drained into the Tiber, considerable remains exist, especially of the r . Cloaca Maxima, which runs from the valley of the Subura, cloacae - under the Forum along the Velabrum, and so into the Tiber by the round temple in the Forum Boarium; it is still in use, and well preserved at most places. Its mouth, an archway in the great quay wall nearly 1 1 ft. wide by 12 high, consists of three rings of peperino " youssoirs," most neatly fitted. The rest of the vault and walls is built of mixed tufa and peperino. 6 Pliny (H.N. xxxvi. 104) gives an interesting account ol what is probably this great sewer, big enough (he says) for a loaded hay-cart to pass along. The mouths of two other similar but smaller cloacae are still visible in the great quay wall near the Cloaca Maxima, and a whole network of sewers exists under a great pail of the Servian city. Some of these are not built with arched vaults, but have triangular tops formed of courses cf stone on level beds, each projecting over the one below a primitive method of construction, employed in the Tullianum The great quay wall of tufa and peperino which lined the Tiber at the mouth of the Cloaca Maxima is also of early date. In later Oreat times this massive wall was extended, as the city grew, quay w all along the bank of the Campus Martius, and, having lost its importance as a line of defence, had frequent flights of stairs built against it, descending to the river. Some of these are shown in one of the fragments of the marble plan (see Jordan, F.U.R. Frag. 169). In 1879 a travertine block was dredged up inscribed P. BARRONIVS . BARBA . AED . CVR . GRADOS . REFECIT, dating from the 1st century B.C. This records the repair of one of these river stairs. 6 The Tullianum is the earliest of the existing buildings of Rome. Imprisonment as a punishment was unknown to Roman law, and hence the Career, where criminals were detained pending trial, was of small dimensions. Its remains are preserved beneath the church of S Giuseppe dei Falegnami, and c below them is the Tullianum, a dungeon where executions Ca "- er - .mum and took place. It is partly cut in the tufa rock of the Capitoline hill and partly built of 2-ft. blocks of tufa, set with thin beds of pure lime mortar, in courses projecting one over the other. Its name is derived, not from Servius Tullius, as Varro (v. 151) asserts, but from an early Latin word, tuttus, a spring of water; its original use was probably that of a cistern or well. It was closed by a conical vault, arched in shape, but not constructionally an arch very like the so-called " treasury of Atreus " at Mycenae, and many early Etruscan tombs. When the upper room with its arched vault, also of tufa, was built the upper part of the cone seems to have been removed, and a flat stone floor (a flat arch in construction) substituted. 7 That its use as a cistern was abandoned is shown by the cloaca which leads from it, through the rock, to a branch of the Cloaca Maxima. This horrible place was used as a dungeon, prisoners being lowered through a hole in the stone floor the only access. The present stairs are modern. The two chambers are vividly described by Sallust (Cat. 55). The entrance to the upper prison was on the left of the stairs leading up from the Forum to the Clivus Argentarius, the road tc the Porta Fontinalis (see fig. 7, General Plan of Ancient Rome). Lentulus and the Catiline conspirators as well as Jugurtha, Vercingetorix and other prisoners of importance, were killed or starved to death in this fearful dungeon, which is called T& 0dpo0pox by Plutarch (Marius, xii.). According to a doubtful tradition of the Catholic Church, St Peter was imprisoned in the Tullianum. The name Mamertine prison is of medieval origin. The front wall of the prison was restored in the reign of libenus A.D. 22, and bears this inscription on a projecting stringcourse C . VIBIVS . C . F . RVFINVS . M . COCCEIVfS M F NERVAJCOS . EX . S.

5 In the upper part of its course the Cloaca Maxima was restored in some places, under the Empire, with a vault of brick-faced concrete ; at the entrance to the Forum a large bend was made when the Basilica Aemilia was extended westwards in 34 B.C.

Forum Romanum and Adjacent Buildings. The Forum Romanum or Magnum, as it was called in late times to distinguish it from the imperial fora, occupies a valley which extends from the foot of the Capitoline hill to the north-west part of the Palatine. Till the construction of the great cloacae it was, at least in wet seasons, marshy ground, in which were several pools of water. In early times it was bounded on two sides by rows of shops and houses, dating from the time of the first Tarquin (Liv. i. 35). The shops on the south-west side facing the Sacra Via, where the Basilica Julia afterwards was built, were occupied by the Tabernae Veteres. 2 The shops on the northern side, being occupied by silversmiths, were called Tabernae Argentariae, and in later times, when rebuilt after a 'fire, were called Tabernae Novae (see Liv. xxvi. 27, xl. 51).* An altar to Saturn (Dionys. i. 34, vi. i), traditionally set up by the companions of Hercules, and an altar to Vulcan, both at the end towards the Capitol, with the temple of Vesta and the Regia at the opposite end, were among the earliest monuments grouped around the Forum. The Lacus Curtius vanished, as Varro says (L.L. v. 148-49), probably with other stagnant pools, when the cloacae were constructed (Liv. i. 38, 56).* Another pool, the Lacus Servilius, near the Basilica Julia, was preserved in some form or other till the imperial period. Under Sulla it was used as a place to expose the heads of many senators murdered in his proscriptions (Cic. Rose. Am. 32, 89; Seneca, De Prov. 3, 7). The Volcanal was an open area, so called from the early altar to Vulcan, and was (like the Comitium) a place of public meeting, at least during the regal period. 6 It was raised above the Comitium, and was a space levelled en the lower slope of the Capitoline hill behind the arch of Severus; the foundations of the altar were discovered in 1898. It was probably much encroached upon when the temple of Concord was enlarged in the reign of Augustus. Fig. 8 gives a carefully measured plan of the Forum, showing the most recent discoveries.
Unlike the fora of the emperors, each of which was surrounded by a lofty wall and built at one time from one design, the architectural form of the Forum Romanum was a slow growth. The marshy battlefield of the early inhabitants of the Capitol and Palatine became, when the ground was drained by the great cloacae, under a united rule the most convenient site for political meetings, for commercial transactions, and for the pageants of rich men's funerals, ludi scenici, and gladiatorial games. 9 For these purposes a central space, though but a small one, was kept clear of buildings ; but it was gradually occupied in a somewhat inconvenient manner by an ever-accumulating crowd of statues and other honorary monuments. On three sides the limits of this open space are marked by paved roads, faced by the stately buildings which gradually took the place of the simple wooden tabernae and porticus of early times. The Comitium 7 was a level space in front of the Curia ; the construction of both is ascribed to Tullus Hostilius. For the position of the Comitium and the Curia 8 see plan of Forum (fig. 8). Varro (L.L. v - 'SS-Sfc) gives the following account of the buildings which were grouped along the northern angle of the Forum:
" Comitium ab eo quod coibant eo comitiis curiatis et litium causa. Curiae duorum generum, nam et ubi curarent sacerdotes res 1 See Tac. Hist. iii. 74, 85; Suet. Vit. 17.
2 See Livy (xliv. 16), who mentions a house of P. Africanus, " pone veteres ad Vortumni signum," which was bought by T. Sempronius to clear the site for the Basilica Sempronia in 169 B.C. This basilica was afterwards absorbed in the Basilica Julia.
8 Hence these two sides of the Forum are frequently referred to in classical writings as " sub veteribus " and " sub novis."
4 In later times it was an enclosed space containing an altar; it is described by Ovid (Fast. vi. 403) ; according to one tradition it marked the spot where Curtius's self-immolation filled up the chasm which had opened in the Forum (see Dionys. ii. 41). (See below.)
'See Dionys. ii. 50, vi. 67; Plin. H.N. xvi. 236; Plut. Quaes. Rom. 47.
* The first gladiatorial show in Rome was given in 264 B.C. in the Forum Boarium by D. Junius Brutus at his father's funeral (Liv. Epit. xvi.), the first in the Forum Romanum in 216 B.C. (Liv. xxiii. 30). See also Liv. xxxi. 50, xli. 28; and Suet. Goes. 39; Aug. 43; and Tib. 7.

1 Liyy (xlv. 24) indicates their relative positions by the phrase " comitium vestibulum Curiae."

The curia or senate-house passed through many vicissitudes. 1 At first called Curia Hostilia, from its founder Tullus Hostilius (Liv. i. 30), it lasted till 52 B.C., when it was burnt at the funeral of Clodius, and was then rebuilt by Faustus Sulla, and from his gens called Curia Cornelia (Dio Cass. xl. 50). It was again rebuilt by Julius Caesar, and dedicated by Augustus (29 B.C.) under the name of the Curia Julia, as recorded in the inscription of Ancyra (q.v .) CVRIAM . ET. CONT1NENS . El . CHALCIDICVM . . . FECl. Little is known about the adjoining buildings called the Athenaeum and Chalcidicum; Dion Cassius (Ii. 22) mentions the group. In the reign of Domitian the Curia Julia was restored (Prosp. Aquit. p. 571), and it was finally rebuilt by Diocletian. The existing church of S. Adriano is the Curia of Diocletian, though of course much altered, and with its floor raised about 20 ft. above the old level. _ The level of the entrance was raised in the middle ages, and again in 1654. Sixteenth-century drawings and engravings show the lower level. The ancient bronze doors now at the end of the nave of the Lateran basilica originally belonged to this building, and were removed thence by Alexander VII. The brick cornice and marble consoles, covered with enriched mouldings in stucco, and the sham marble facing, also of stucco, if compared with similar details in the baths of Diocletian, leave no doubt as to this being a work of his time, and not, as was at one time assumed, the work of Pope Honorius I. (A.D. 625-38) who consecrated it as the church of S. Adriano.
From the Curia a flight of steps led down to the Comitium (Liv. i. 36), a space consecrated as a templum according to the rules of augury (Cic. De Or. iii. 3) and used for the meetings of the Comitia Curiata, and for certain religious ceremonies performed, after the fall of the monarchy, by the rex sacrtficutus. It contained ancient monuments, relics, such as theficus ruminalis, and the supposed tomb of Romulus, whose site was marked in later times by a " black stone " (lapis niger). Facing the Curia stood the platform from which speakers addressed the people, adorned in 338 B.C. with the beaks of the ships captured from the Latins at the naval victory of Antium and hence called the rostra. Caesar determined to remove the rostra from the Comitium to the Forum, and this plan was carried out after his murder. From the original rostra Cicero delivered his Second and Third Catiline Orations, and they _.,. were the scene of some of the most important political * struggles of Rome, such as the enunciation of their laws by the Gracchi. Beside the Comitium another monument was erected, also adorned with beaks of ships, to commemorate the same victory at Antium. This was the Columna Maeniana, so called in honour of Maenius (Plin. H.N. xxxiv. 20, vii. 212). The Columna Duilia was a similar monument, erected in honour of the victory of C. Duilius over the Punic fleet in 260 B.C.; a fragment of it with inscription (restored in imperial times) is preserved in the Capitoline Museum. 10 Columns such as these were called columnae rostratae.
In 1899-1900 the site of the Comitium which was considerably reduced in extent by the building of the later Curia was excavated by Commendatore Boni, in some parts as far as the virgin soil. 11 Remains of walls and pavements of various periods (some very early) were discovered; some of the walls, there is no doubt, supported the platform of the early rostra, which appears to have been at first rectangular and at a later time curved. Opposite to the Curia is a square paved with black marble slabs, which it is natural to identify with the lapis niger of tradition. Beneath this pavement was found a group of early monuments, which were at some time destroyed and afterwards covered over. We are told on the authority of Varro that Romulus was buried in front of (or behind) the rostra, and that two lions were sculptured as guardians of his tomb; and we find in fact a foundation (D, fig. 9) from which project two moulded bases of tufa (A, B) on which the lions may well have stood, on either side of a block (C) which might serve as an altar. Beside this tomb (if such it be) stood the trunk of a tufa column (E) and a rectangular stele (F) which bears on all its faces an inscription written alternately upwards and downwards, so that only the ends of the lines can be read. That it is the earliest specimen of the Latin language is undoubted; and it certainly mentions the rex. But after the expulsion of the kings the rex ' On the Curia and its vicissitudes see Lanciani, L'Auia e gli Uffici del Senato Romano (1883).
IO The column itself is a copy made by Michelangelo; it is at the foot of the stairs of the Palazzo dei Conservatori.

The Capitol Forum Romanum ity , by pcnnission ot K*rl sacrificulus performed his functions in the Comitium, and the inscription may refer to him. This may be the stele to which Dionysius of Halicarnassus refers as marking the tomb of Hostus Hostilius (father of Tullus Hostilius) whose site (according to those who believed in the translation of Romulus to heaven) was marked by the lapis niger.

The Senaculum appears to have been a place of preliminary meeting for the senate before entering the Curia (Liv. xli. 27; g eaa . Val. Max. ii. 2, 6) ; it adjoined the temple of Concord, culum a "^ wnen tn i s was rebuilt on an enlarged scale in the reign of Augustus it appears probable that its large projecting portico became the Senaculum.
FIG. 8. The Roman Forum A great part of the north-east side of the Fcrum was occupied by two basilicae, which were more than once rebuilt under different names. The first of these appears to have been adjacent ... to the Curia, on its west side; it was called the Basilica . f Porcia, and was founded by the elder Cato in 185 B.C. (see Liv. xxxix. 44, and Plut. Cato Major, 19); it was burnt with the Curia at Clodius's funeral. On the north side of the Forum another basilica, called Aemilia et Fulvia (Varro vi. 4), was built in 179 B.C. by the censors M. Fulvius and M. Aemilius Lepidus ; * it stood, according to Livy (xl. 51), " post argentarias novas," the line of silversmiths' shops along the north-east side of the Forum. In 50 B.C. it was rebuilt by L. Aemilius Paulus with Caesar's money (Plut. Goes. 29; Appian, Bell. Civ. ii. 26), and was more than once restored within the few subsequent years by members of the same family. Its later name was the Basilica Pauli, and it was remarkable for its magnificent columns of Phrygian marble (Plin. H.N. xxxvi. 102) or pavonazzetto. Part of the western end was still standing in the 16th century, and was drawn by Giuliano da Sangallo (Huelsen, The Roman Forum, fig. 61). Recent excavations have shown that it was approached from the Forum by a flight of steps leading to a two-storeyed colonnade. Behind this was a row of tabernae in the middle of which was the entrance to the main hall, consisting in a nave and three aisles (two on the north side).
Near the middle of the north-east side of the Forum stood also the small bronze temple of Janus, 2 the doors of which were shut on those rare occasions when Rome was at peace. 3 A _ . first brass of Nero shows it as a small cella, with richly ,. ornamented frieze and cornice. Another aedicula near that of Janus was the shrine of Venus Cloacina (or the Purifier), on the line of the cloaca which runs under the Basilica Aemilia; 1 The Forum Piscatprium or fish-market appears to have been at the back of this basilica (see Liv. xl. 51).
2 The original temple was one of the prehistoric buildings attributed to Romulus and Tatius (Serv. Ad Aen. i. 291), or by Livy (i. 19) to Numa.

its foundations and plinth were brought to light in 1899 (Liv. iii. 48 ; Plin. H.N. xv. 119).
Fig. 8 shows plan of the rostra as they existed under the Empire. We see an oblong platform about 78 ft. long and 1 1 ft. high above the level of the Forum; its ground floor, paved with Existing herring-bone bricks, is 2 ft. 6 in. below the Forum paving. rostra. j ts en j an( j s ^ e wa lls are of tufa blocks, 2 ft. thick and 2 ft. wide, each carefully clamped to the next with wooden dovetail dowels. Its floor was supported by a series of travertine piers, carrying travertine lintels, on which the floor slabs rested. Outside it was completely lined with Greek marble and had a richly moulded plinth and cornice; the front wall was restored in 1904, and the fragments of the cornice replaced. A groove cut in the top of the cornice shows the place where marble cancel!! were fixed; one of the cornice blocks is partly without this groove, showing that the screen did not extend along the whole front of the rostra. This agrees with a relief on the arch of Constantine, representing the emperor making an oration from the rostra, with other buildings at this end of the Forum shown behind. In this relief the screen is shown with a break in the middle, so that the orator, standing in the centre, was visible from head to foot. Two tiers of large holes to hold the bronze rostra are drilled right through the tufa wall, and even through the travertine pilasters where one happens to come in the way; these holes show that there were nineteen rostra in the lower tier, and twenty above set over the intermediate spaces of the lower row. The back wall of the rostra is of concrete faced with brick. The inside space, under the main floor of the rostra, is coated thickly with stucco the brick wall being studded in the usual way with iron nails to form a key for the plaster.
Immediately behind the rostra is a curved platform approached by steps from the side facing the Capitol. It has been much disputed whether this platform is earlier or later than the rostra ; but the evidence of the construction at the point of juncture platform. seems to s h O w that the hemicycle is the earlier. When the arch of Severus was built, part of the platform of the rostra was cut away and a court of irregular shape was thus formed, from which the rostra was approached by steps. The front wall of the hemicycle was now exposed in its eastern half; this was faced with slabs of porta santa marble, pilasters of africano, and a moulded plinth of white marble, whose blocks bear the Greek characters T, A, E, Z, H, 6, K; the omissions make it clear that the blocks were removed from some other building. A number of holes in the marble, some of which contain fragments of metal pins, show that bronze ornaments were at one time attached to the facing. The hemicycle has been identified (without sufficient reason) with the Graecostasis, a platform near the rostra reserved for foreign embassies (Varro, L.L. v. 155; Cic. Q.F. ii. i), which continued to exist throughout the imperial period and was restored by Antoninus Pius (Vita 9, 2). It is, however, far more likely that it represents the original form of the rostra as removed to the Forum according to Caesar's design. 1 When the oblong platform was built (perhaps by Trajan) it was approached from the back by the hemicycle. The bronze rostra on the imperial structure were believed to be the original beaks from Antium, moved from the old rostra (Florus, i. n). On its marble platform stood many statues, 1 e.g. of Sulla, Pompey, two of Julius Caesar, and others (Dio Cass. xlii. 18 and xliv. 4) ; these are represented on a bas-relief from the arch of Constantine. It is further commonly believed that the marble plutei which now stand in the centre of the Forum once decorated the rostra. Owing probably to the weight of the many statues proving too much for the travertine piers, which are not set on their natural beds but endways, and therefore are very weak, the structure seems to have given way at more than one time, and the floor has been supported by piers and arches of brick-faced concrete, 1 See Mau in Rom. Mitt. 1906, pp. 230 ff.
2 The original rostra had specially honorary statues to those Roman ambassadors who had been killed while on foreign service (Liv. iv. 17); these were probably removed during Cicero s lifetime (Cic. Phil. ix. 2, 4; see also Dio Cass. xliii. 49, and Plin. H.N. xxxiv. 23, 2$). Ghastly ornaments fixed to these rostra in the year 43 B.C., shortly after they were built, were the head and hands of the murdered Cicero (Appian, Bell. Civ. iv. 20; Dio Cass. xlvii. 8; Juv. x. 120), as on the original rostra had been fixed many heads of the chief victims of the proscriptions of Marius and Sulla (see Appian, Bell. Civ. i. 71, 94; Florus iii. 21). The denarius of the tens Lollia with the legend PALIKANVS represents th<? rostra of the late republican period.
inserted either in place of or at the sides of the shattered piers. These later additions, apparently of the 3rd and 4th centuries, are omitted in fig. 8 for the sake of clearness. In or about A. p. 470 the fagade of the rostra was prolonged northwards by an addition in very poor brickwork, apparently to celebrate a naval victory over the Vandals. At the northern end of the curved platform there is a cylindrical structure of concrete faced with brick and lined with thin marble slabs; it is in three stapes, each diminishing in size, and ''"" appears to be an addition of about the time of Severus. This is usually identified with the Umbilicus Romae, or central point of the city, mentioned in the Notitia and the EinsiedelnMS.(Jordan, Topographic der Stadt Rom, ii.65). Near the rostra, below the temple of Saturn, stood the Millianum Aureum, a marble column sheathed in gilt bronze and inscribed with the names and distances of the chief towns on the roads which radiated from the thirty-seven gates of Rome (Plin. H.N. iii. 66). It was set up by Augustus in 20 B.C., and its position " sub aede Saturni " is indicated by Tacitus (Hist. i. 27; see schol. on Suet. Otho. 6, and Plut. Galba, 24). The Miliarium is mentioned in the Notitia (Reg. viii.) as being near the Vicus Jugarius. Its precise position cannot be determined. Fragments of a marble cylinder and cornice with floriated reliefs, now lying in front of the temple of Saturn, probably belonged to this monument; they were found in 1835 near the supposed site.
The position of the temple of Saturn is indicated in Man. Anc. (see below, n. 6) and shown on the marble plan, and is also identified _ by various passages in ancient writers. Varro (L.L. v. 42)
speaks of it as being infaucibus Capitolii ; Servius (Ad Aen. ii. 115) says that it is in front of the Clivus Capitolinus, and near the temple of Concord (see Plate VIII.). It was built against a steep slope or outlying part of the Capitoline hill ' (cf. Dionys. i. 34) on the site of a prehistoric altar to Saturn, after whom the Capitoline hill was originally called Mons Saturnius. The public treasury was part of this temple (Serv. Ad Aen, ii. 116, and Macrob. Sat. i. 8). Tne original temple is said by Varrp (ap. Macrob. i. 8) to have been begun by the last Tarquin, and dedicated by T. Larcius, the first dictator, 498 B.C.; but Dionysius (vi. i) and Liyy (ii. 21) attribute it to the consuls A. Sempronius and M. Minucius in 497 B.C. It was rebuilt on a larger scale by L. Munatius Plancus in 42 B.C. (Suet. Aug. 29). The only part remaining of this date is the very lofty podium of massive travertine blocks, and part of the lower course of Athenian marble, with which the whole was faced. In the 16th century a piece of the marble frieze was found, inscribed L, . PLANCVS . L . F . CO3 . IMPER . ITER . DE . MANIB . (C.I.L. vi. 1316). The erection of the six granite columns in the front and two at the sides, with their clumsily patched entablature, bearing the inscription SENATVS . POPVLV3QVE . ROMANVS . INCENDIO . CONSVMTVM . RE3TITVIT, belongs to the last rebuilding in the time of Diocletian. Some of these fine columns are evidently earlier than this rebuilding, but were refixed with rude caps and bases. One of the columns is set wrong way up, and the whole work is of the most careless sort. Part of the inscription, once inlaid with bronze, recording this latest rebuilding, still exists on the entablature. On the Forum side the temple is flanked by the Vicus Jugarius, while the steep Clivus Capitolinus winds round the front of the great flight of steps leading up to the cella, and then turns along the north-west side of the temple. 2 The Vicus Jugarius (see fig. 8), part of the basalt paving of ' cu . which is now exposed, was so called (see Festus, ed. Miiller, p. 104) from an altar to Juno Juga, the guardian of marriage. Starting from the Forum, it passed between the temple of Saturn and the Basilica Julia, then close under the cliff of the Capitolium (see Liv. xxxv. 21) and on to the Porta Carmentalis. It was spanned at its commencement by a brick-faced arch lined with marble, the lower part of which exists, and is not earlier than the 3rd or 4th century. 3 At this end of the Forum the arch of Tiberius was built beside the Sacra Via. It was erected in A.D. 17, to commemorate the recovery of the standards lost by Varus. 4 The concrete foundation has recently been exposed.
The Basilica Julia' occupies a great part of the south-west side of the Forum, along the line of the Sacra Via; its ends are bounded by the Vicus Jugarius and the Vicus Tuscus. It was begun by Julius Caesar, who dedicated it when still unfinished, on the 26th of September 46 B.C., completed Basilica Julia.
1 Below the temple of Saturn the Clivus Capitolinus is carried on an arched substructure of somewhat irregular opus reticulatum. -This has been described (but without much probability) as the rostra of Caesar.
2 A portion of these streets with part of the temple of Saturn and the Basilica Julia is shown on fragments of the marble plan (see Plate VIII.).
3 One side of this gate was built against one of the marble piers of the Basilica Julia, a perfect print of which still exists in the concrete of the gate, though the marble pier itself has disappeared. The other side of the gate abutted against the marble-lined podium of the temple of Saturn.
4 See Tac. Ann. ii. 41 , who says it was propter aedem Saturni. 'See Suet. Aug. 29; Gerhard, Bas. Giulia, etc. (1823); and Visconti, Escavazione della Bas. Giulia (1872).
by Augustus, and again rebuilt by him after a fire, as is recorded in Man. Anc. 4, 13," in an important passage which gives its complete early history. It consisted of a central hall with aisles, galleries and clerestory, surrounded on three sides by a colonnade in two storeys approached by steps; on the S.W.a row of rooms or tabernae took the place of the colonnade. The central nave was paved with richly coloured oriental marbles, namely pavonazzetto, cipollino, giallo and africano. The covered aisles are paved with large slabs of white marble. 7 Many tabulae lusoriae, or gambling boards, art scratched on this marble paving (cf. Cic. Phil. ii. 23)." Low marble cancelli, with moulded plinth, closed the otherwise open arches of the basilica; many fragments exist, and one piece of the subplinth is still in situ. This basilica held four law-courts, which in important cases held joint sessions. Trajan and other emperors held lawcourts there (Dio Cass. Ixxxviii. 10). An inscription found near it (C.I.L. vi. 1658) records its restoration by Septimius Severus in A.D. 199, after a fire; it was again burnt in 283 and restored by Diocletian. These fires had destroyed nearly all the fine marble arches of Augustus; and Diocletian rebuilt it mostly with brick or travertine piers, portions of which remain.' A final restoration is recorded in inscriptions discovered at various times from the 16th century onwards, as being carried out by Gabinius Vettius Probianus, praefect of the city in 377 ; one of these is on a pedestal which now stands in the Vicus Jugarius. Suetonius (Cal. 37) mentions that it was one of Caligula's amusements to throw money to the people below from the roof of this basilica, which formed a link in the bridge by which this maniac connected the Palatine with the Capitolium.
The Vicus Tuscus passes from the Sacra Via between the Basilica Julia and the temple of Castor to the Velabrum and Circus Maximus; its basalt paving has been exposed at many points along its whole line. A very early statue of Vortumnus stood in this street, a little to the south-west of the Basilica Julia, where part of its pedestal was found in 1 549 inscribed VORTVMNVS TEMPORIBVS DIOCLETIANI . ET . MAXIM1ANI . . . (C.I.L. vi. 804; 10 see also Pseudo-Ascon, Ad Cic. Verr. ii. I, 59). The Vicus Tuscus was also called Thurarius, from shops of perfumesellers (see Schol. ad Hor. Sat. ii. 3, 228, and Ep. ii. i, 269). It is the street along which processions passed, mentioned by Cicero (Verr. ii. I, 59) as extending a signo Vertumni in Circum Maximum.
The temple of Castor 11 or, more properly, of " the Castores," i.e. Castor and Pollux on the south-east side of the Vicus Tuscus was founded to commemorate the apparition in the Forum f emp i e of the Dioscuri, announcing the victory of Aulus Postumius /casto at Lake Regillus, 496 B.C., and was dedicated in 484 B.C. by the son of A. Postumius (Liv. ii. 20, 42; Dionys. vi. 13; Ov. Fast. i. 706). In 119 B.C. it was restored by the consul L. Caecilius Metellus Dalmaticus (Ascon. In. Cic. Pro Scaur. 46). and finally rebuilt in the reign of Augustus by Tiberius and Drusus, A.D. 6 (Suet. Tib. 20; Ov. Fast. i. 705; Dio Cass. Iv. 8, 27); the three existing Corinthian columns and piece of entablature, all very delicate and graceful in detail, and of the finest workmanship, in Pentelic marble, belong to a still later restoration under Trajan or Hadrian. One point shows Roman timidity in the use of a lintel: the frieze is jointed so as to form a flat arch, quite needlessly, with the object of relieving the weight on the architrave. Its plan, hexastyle, with only eleven columns on the sides, is shown in fig. 8. It had a lofty podium, faced with marble and decorated with a heavy cornice and pilasters, one under each column. The podium is an interesting example of the enormous solidity of Roman buildings of the best period. Solid tufa walls, 8 ft. thick, are built under the whole of the cella and the front row of columns, while the columns of the sides rest on spurs of similar walling, projecting at right angles from that under the cella; the part immediately under the columns is of travertine, and the spurs are united and strengthened laterally by massive flat arches, also of travertine. Between the foundations of the columns were chambers used as offices, etc. With the exception of a small chamber under the steps, entered from the Vicus Tuscus, the entire podium is filled up by a solid mass of concrete, made of broken tufa, pozzolana and lime, the whole forming a lofty platform, about 22 ft. high, solid as a rock, on which the columns and upper structure are erected. The podium contains " Forvm . Ivlivm . et . basilicam . qvae . fvit . inter . aedem . Castoris . et . aedem . Satvrni . coepta . profligataqve . opera . a . patre. meo. perfect, et. eandem. basilicam. consvmptam. incendio . ampliatp . eivs . solo . svb . titvlo . nominis . filiorvm . inchoavi . et . si.^vivvs . non . perfecissem . perfici . ab . haeredibvs . [meis . ivssil]." The filii here referred to are Augustus's grandsons, Gaius and Lucius, adopted by him in 17 B.C. (see Dio Cass. Ivi. 27).
7 Three medieval lime-kilns were found by Canina within this basilica, which accounts for the scantiness of the existing remains.
8 A few have inscriptions, e.g. " Vinces . gaudes: perdes . plangis."
9 The whole building has unhappily been much falsified by needless restoration.
10 A drawing of this pedestal, which is now lost, with MS. note by Ligorio, exists in Cod. Vat. 3439, fol. 46.
11 The temple of Castor is shown on two fragments of the marble plan, and its position is also indicated by the passage in the Man. Anc. quoted above (note 6).
a few remains 'of the earliest temple, built of blocks of grey-green tufa. Two fragments of mosaic, with simple lozenge pattern in white marble and basalt, still exist in the cella of this temple. The level of the mosaic, which probably belongs to the rebuilding of Tiberius, lies considerably below that of the later floor, which seems to date from Hadrian's reign. It has all the characteristics of early mosaic very small tesserae fitted with great accuracy, like the early mosaic in the Regia. The temple of Castor was often used as a meeting-place for the senate, and its lofty podium formed a tribunal for orations. 2 The Fons or Lacus Juturnae (see Ov. Fast. i. 705, and Dionys. vi. 13), at which the Dioscuri were fabled to have watered their horses, was beside their temple ; the precinct was discovered in 1900-1. The Lacus itself, a basin 16} ft. square and 6J ft. deep, is immediately opposite the three standing columns of the temple; in the centre is a base of opus reticulatum, which supported statues of the Dioscuri; an altar with reliefs, together with other sculptures, has been found close by, and a few yards off is a small chapel or aedicula, intended for a statue of Juturna, and in front of it a well-curb (puteal) of white marble, set up by the aedile M. Barbatius Pollio in the reign of Augustus.
Close to the temple of Castor, at the angle of the Forum, stood the arch of Augustus, set up in 20 B.C. to commemorate the recovery . . of the standards taken from Crassus by the Parthians.
Its foundations were discovered in 1888; it had three ' bays, and rested on the pavement of a street which before the time of Augustus formed the E. boundary of the Forum.
On the other side of the Sacra Via stand the remains of the temple of Divus Julius, erected by Augustus. Though little beyond its _ . concrete core is left, its plan can be fairly well made out f rom the voids in the concrete, which show the position of the tufa foundations under the walls and columns (as in the temple of Castor). The temple itself, a hexastyle prostyle building, with close intercolumniation (Vitr. iii. 2), stood on a lofty podium with a curved recess in the front between two flights of stairs (see Plate VIII.). The wall which now fills up the recess is a late addition. In 1898 the base of a large altar was discovered in the niche, doubtless that mentioned by Appian (Bell. Civ. ii. 148). The podium, which projects in front of the temple itself, was adorned with beaks from the ships taken at Actium (Dio Cass. li. 19), and hence it was called the Rostra Julia, to distinguish it from the other rostra described above. Both were used for the funeral orations in honour of Augustus (Suet. Aug. loo; see also Dio Cass. liv. 35). Besides the concrete core and the curved tufa wall ot the recess, little now exists except a small bit of the mosaic of the cella floor and some fragments of the cornice and pediment, of fine Greek marble. This temple is represented on coins of Augustus and Hadrian.
The temple of Vesta, founded according to tradition by Numa,* stands at the southern angle of the Forum on the ancient line of the Sacra Via (Ov. Trist. iii. I, 28). No shrine in Rome /emp/c wag e q ua i ; n sanctity to this little circular building, which 5 a * contained the sacred fire and the relics on which the welfare and even the existence of Rome depended. The original building was destroyed in 390 B.C. by the Gauls; it was burnt again in 241 B.C., again in the great fire of Nero's reign, and then in the reign of Commodus; after this it was rebuilt by Severus, to whose age belong the fragments of columns, cornice and other architectural features now lying around the ruined podium. With the aid of coins 4 and a relief preserved in the Uffizi at Florence 5 it is possible to make a sufficiently accurate restoration of the temple.' It consisted of a circular cella, surrounded by eighteen columns, with screens between them; the circular podium, about 10 ft. high, still exists, mainly of concrete with some foundations of tufa blocks, which may belong to the original structure. Recent excavations have disclosed a pit (favissa) in the middle of the podium, where the ashes of the sacred fire were temporarily stored. In the time of Pliny (H.N. xxxiv. 7) the tholus or dome over the cella symbolizing the canopy of heaven (Ov. Fast. vi. 276) was covered with Syracusan bronze. Its position near the temple of Castor is mentioned by Martial (i. 71-73).' The Regia, or office of the pontifex maximus, was on the Sacra Via, close by the temple of Vesta. It [also was traditionally founded by Numa, and used as his dwelling-house; it _ . Regia.

2 The front of the podium was decorated with ships' beaks. One of the mad acts of Caligula was to make the temple of Castor into the vestibule of his palace by breaking a door through the back of the cella (Suet. Cal. 22).

escaped. Ovid (Trist. iii. I, 28) describes this end of the Forum thus:
" Haec est a sacris quae via nomen habet, Hie locus est Vestae, qui Pallada servat et ignem, Hie fuit antiqui Regia parva Numae."
It was again damaged by fire in 148 B.C. and 36 B.C., after which it was rebuilt in marble by Cn. Domitius Calvinus. and its outer walls inscribed with the lists of consuls and triumphs (fasti consulares et triumphales) of which many fragments have been recovered. Recent excavations have brought to light the tufa foundations of the republican building, including a round substructure, which may have supported the sacrarium Martis, in which were preserved the ancilia or sacred shields and spears (Cell. iv. 6), and an underground cistern, which has been brought into connexion with the shrine of Ops Consiva (Varro, L.L. vi. 21). The official residence of the pontifex maximus was not the Regia, but the domus publica; when Augustus succeeded to the office, he conveyed a part of his residence on the Palatine to the state in order to satisfy the claims of tradition, and presented the domus publica to the vestals.
The excavations of 1883-84 laid bare remains of this very interesting building, and showed that it was a large house extending close up to the Atrium Vestae; its orientation corresponded with that of the Regia. The existing remains are of several dates first, walN of soft tufa, part possibly of the earliest building; second, walls of hard tufa, of rather later date; and lastly, concrete walls faced with brick, decorated with painted stucco, and columns of travertine, also stuccoed and painted, 8 with a large quantity of fine mosaic of that early sort which has very small tesserae put together with great accuracy. These valuable remains were preserved in spite of the erection of later buildings over them, because the levels of the later floors were higher than those of the Regia, and thus covered and protected the mosaics and lower parts of the walls and columns.
The Atrium Vestae, or house of the vestals, like the temple, wa* many times burnt and rebuilt; the existing building, which was excavated in 1883-84 and more completely in I9pi, seems . . to have been built after the great fire of A.D. 64, and to V, have been restored or enlarged several times by the Flavian emperors, who added the colonnade; Hadrian, who built the tablinum and other rooms at the end ;the Antonines, and Septimiu* Severus, who restored the whole after the fire of A.D. 192.' It consists of a large atrium or quadrangle with columns of cipollino. At one end is the tablinum, with three small rooms on each side of it probably for the six vestals. A bathroom, bakehouse, servants' offices, and some rooms lined with rich marbles extend along the south-west side. This extensive building is set against the side of the Palatine, which is cut away to admit the lower storey. Thus the level of the first upper floor is nearly the same as that of the Nova Via, on which it faces, about 23 ft. above the ground floor. 1 he upper floor is in part well preserved; it contains a large suite of bath and other rooms, which were probably the sleeping apartments of the vestals. All the better rooms and the baths are lined with polished marbles, many of great beauty and rarity; the floors are mostly mosaic of tessellated work. The paving of the tablinum was a beautiful specimen of inlay in porphyry and marble. In many places alterations and clumsy patchings of the 4th and 5th centuries are apparent. A number of statues of the chief vestal, or virgo vestalis maxima, with inscribed pedestals, were found in the atrium, mostly of the 3rd century, though a few are earlier; these are of especial interest as illustrating the sacerdotal dress of the vestals. 10 Nothing but the Nova Via separates the Atrium Vestae from the imperial palace (see Plin. Ep. vii. 19; Aul. Cell. i. 12), which extends over the site of the Lucus Vestae " qui a Palatii radice in Novam Viam deyexus est " (Cic. De Div. i. 45). A curious octagonal structure in the middle of the atrium looks very much like a border for flower-beds; and it is possible that this miniature garden was made by the vestals when the Lucus Vestae ceased to exist. By the main entrance from the Forum stood a small aedicula a large pedestal, at the angles of which were columns supporting an entablature." It no doubt contained a statue of Vesta, there being none within the temple. It is of the time of Hadrian. Gratian confiscated the house and endowments of the vestals in A.D. 382, but the atrium continued to be partly inhabited for many centuries later by imperial or papal officials. 11 In September 1884 a road was 8 The columns were crimson, the travertine rain-water gutter bright blue, and the inner walls had .simple designs in panels of leaf ornament and wreaths.
A full account of the Atrium Vestae and its successive restorations is given in Miss E. B. Van Deman's Atrium Vestae vi9og).
10 The most important of these have been removed to the Museo delle Terme.
11 The front is inscribed SENATVS . POPVLVSQVE . ROMANVS . PECVNIA .PVBL1CA . FAC1ENDAM . CVRAVIT.
12 In the excavations of December 1883 a pot was found in the north corner containing 830 silver pennies of English kings of the 9th and loth centuries Alfred the Great, Edward I., Aethelstan, Eadmund I., and others. A list of these is given by De Rossi in Lanciani's work, L'Atrio di Vesta (Rome, 1884). None are later discovered leading up past the tablinum end of the atrium front the Sacra Via to the Nova Via. In about the 4th century this roac appears to have been blocked up at the Nova Via end by a building which adjoined the Atrium Vestae.
At the north-east corner of the Forum stood the arch of p. Fabius Maximus, consul in 121 B.C., called Allobrogicus from his victory Arch of over the Allobroges (Schol. on Cic., In Verr., Actio i. 7) i Hhiux. Liv. Ep. Ivi. ; Plin. H.N. vii. 166). It marked the extreme limit of the Forum in this direction (Cic. Pro Plane, 7, 17), as the rostra did at the other end. Remains of this arch were dug up and mostly destroyed in 1546, near the temple of Faustina; on one of the fragments then discovered was inscribed Q.FABIVS.Q. F. MAXSVMVS.AED.CVR.REST. (Dessau Inscr. Lai. Sel. 430). About twenty-five other fragments were found in 1882.* The temple of Faustina the elder stands at the east angle of the Forum, facing the later line of the Sacra Via. It is prostyle hexa_ style, and has monolithic columns of cipolhno and a rich /emp/e of enta bl a ture of Greek marble, with graceful reliefs of Faustina. grifi j ns and candelabra on the frieze. 2 The walls are of massive peperino, once lined with marble. On the front is inscribed DIVO. ANTONINO. ET. DIVAE. FAVSTINAE. EX. S. C. This temple, built by Antoninus Pius in memory of his wife, who died in 141, was after his death dedicated also to him, and the first line was then added (Vita Ant. Pii, 6). In the Middle Ages it was consecrated as the church of S. Lorenzo in Miranda, and a great part of its cella has been destroyed. The front is now excavated to the original level. This temple is shown on the reverse of several coins of Antoninus Pius; some have the legend DEDICATIO. AEDIS.
The space between the north-west end of the Forum and the Tabularium is occupied by a range of important buildings (see Temple at Plate VIII.). The chief of these is the temple of Concord Concord. ( see Festus, ed. Miiller, p. 347) shown on a fragment of the marble plan, founded by Camillus in 366 B.C. (Plut. Cam. 42), and restored by Opimius after the death of C. Gracchus (121 B.C.). It was afterwards rebuilt by Tiberius out of the spoils gained in Germany; it was rededicated by Tiberius in A.D. 10 in his own name and that of his brother Drusus (who had died in B.C. 9) [Suet. Tib. 20; Dio. Cass. Iv. 25]. It is shown with unusual minuteness on the reverse of a first brass of Tiberius. The existing remains 3 are of the rebuilding by Tiberius, and show that it was unusual in plan, having a large cella much wider than its depth, and a very large projecting portico. Its construction is an interesting example of the Roman use of many different materials. The lower part of the walls was of massive tufa blocks, the upper part of the cella of travertine; and the inner low wall, which supported ranges of internal columns, was of mixed concrete, tufa and travertine. The whole was lined with marble, white outside, and rich oriental marbles inside (see fig. 4), which were also used for the pavement. The door-sill is made of enormous blocks of porta santa marble, in which a bronze caduceus (emblem of Mercury) was inlaid. Between the internal columns of the cella stood rows of statues; and the temple also contained a large collection of pictures, engraved gems, gold and silver plate, and other works of art, mostly the work of ancient Greek artists (see Plin. H.N. xxxiv. 19, xxxv. 36, 40, xxxvi. 67, xxxvii. 2). 'On the apex of the pediment was a group of three figures embracing; the tympanum was filled with sculpture; and statues were set in the open porch. Though now only the podium and the lower part of the cella wall exist, with foundations of the great flight of steps, many rich fragments both of the Corinthian entablature and of the internal caps and bases are preserved in the Tabularium; and some of the marble lining is still in situ. The Einsiedeln MS. gives part of the inscription of the front S.P.Q.R. AEDEM. CONCORDIAE. VETVSTATE. COLLAPSAM . IN.MELIOREM . FACIEM.OPERE . ET.CVLTV . SPLENDIDIORE. RESTITVERVNT (C.I.L. vi. 89).* than 946, and a bronze fibula inlaid with silver with the name of Pope Marinus II. (942-46) makes it seem probable that this hoard was concealed during his pontificate.
1 Not. degli Scavi (1882), p. 225.
1 This finely sculptured frieze is almost an exact copy of that on the temple of Apollo at Miletus.
* The size of the earlier and smaller temple is indicated by the rough blocks on the face of the wall of the Tabularium, close against which the temple stands. When the Tabularium was built it was not thought worth while to dress to a smooth face that part of its wall which was concealed by the then existing temple of Concord.
4 Little is known of the Basilica Opimia, which probably adjoined the earlier temple of Concord, and the existing building appears also to have occupied the site of the Senaculum (see Festus, ed. Muller, p. 347). For various exciting scenes which took place in the temple of Concord and on its steps, see Cic. Phil. vii. 8; Sallust, Bell. Cat. if). Another temple of Concord, built in 216 B.C., stood on the Capitoline Arx (Liv. xxii. 33, xxiii. 21); and a bronze aedicula of Concord in the Area Vulcani, which must have been close by the great temple. This was dedicated by Cn. Flavius, 305 B.C. (see Liv. ix. 46); according to Pliny (H.N. xxxiii. 19) it stood " in The temple of Vespasian stands close by that of Concord, abutting on the Tabularium in a similar way, and blocking up a doorway at the foot of a long flight of steps (see fig. i). It consists of a nearly square cella with prostyle hexastyle portico of ^ el "P' e * the Corinthian order; three of the columns are still standing, with their rich entablature, the frieze of which is > >ailtta ' sculptured with sacred instruments. The walls are of enormous blocks of travertine with strong iron clamps; the whole was lined with white Pentelic marble outside, and inside with coloured oriental marbles. There was an internal range of columns, as in the temple of Concord. This temple was begun by Titus in A.D. 80, in honour of his father Vespasian, and finished by Domitian, who dedicated it to Vespasian and Titus. The inscription on the entablature, given in the Einsiedeln MS., records a restoration by Severusand Caracalla DIVO. VESPASIANO. AVGVSTO.S.P.Q.R. 1MPP. CAESS. SEVER VS.ET.ANTONINVS. PII. FELIC. AVGG. RESTITVERVNT; part of the last word only now exists.
In the narrow space between the temples of Concord and Vespasian (only about 7 ft. in width) a small brick and concrete edifice stands against the Tabularium. In it was found an inscribed base dedicated to Faustina the younger by one of the viatores (messengers) of the quaestors, who probably had their office here.
The next building is the Porticus Deorum Consentium, a colonnade in two wings which join at the obtuse angle, with a row of small rooms or shrines partly cut into the tufa rock of the hill behind. This conjunction of twelve deities was of \ r Etruscan origin; they were six of each sex and were called Senatus Deorum (Varro, L.L. viii. 70, and De Re Ji Rust, i. i). 6 The columns are of cipollino with Corinthian caps; on the frieze is an inscription recording a restoration by Vettius Agorius Praetextatus, praefect of the city in A.D. 367. Under the marble platform is a row of seven small rooms, the brick facing of which is perhaps of the Flavian period.
The arch of Severus stands by the rostra, across the road on the north-east side of the Forum; the remains of the ancient travertine curb show that originally the road went along a rather different line, and was probably altered to make room Arch of for this great arch, which was accessible only by steps, Seyerus. and was not used for ordinary traffic. It was built in A.D. 203, after victories in Parthia, and was originally set up in honour of Severus and his two sons M. Aurelius Antoninus (Caracalla) and Geta. Caracalla, after murdering Geta, erased his name from all monuments to his honour in Rome. Representations of the arch on coins of Severus show that its attic was surmounted by a chariot of bronze drawn by six horses, in which stood Severus crowned by Victory; at the sides were statues of Caracalla and Geta, with an equestrian statue at each angle. The arch, except the base, which is of marble-lined travertine, is built of massive blocks of Pentelic marble, and has large crowded reliefs of victories in the East, showing much decadence from the best period of Roman art.
The central space of the Forum is paved with slabs of travertine, much patched at various dates; it appears to have been marked out into compartments with incised lines (see Plate VIII.), the use of which is not known. There are also square Central holes which probably held masts on which awnings could space of be spread. Numerous clamp-holes all over the paving Forum, show where statues and other ornaments once stood. The recorded number of these is very great, and they must once have thickly crowded a great part of the central area. Two short marble walls or plutei covered with reliefs, discovered in 1872, stand on the north side. The rough travertine plinth on which they have been set is evidently of late date. Each of these marble screens has (on the inside) reliefs of a fat bull, boar and ram, decked out with sacrificial wreaths and vittae the suovetaurilia. On the outside are scenes in the life of Trajan: in both cases the emperor is speaking from the rostra. On one we also see him seated on a suggestus instituting a charity for destitute children in A.D. 101 a scene similar to one shown in one of his first brasses with the legend ALIM[ENTA] ITALIAE; 6 at the other end the emperor stands on the rostra, on which the two tiers of beaks are shown; he is addressing a crowd of citizens. In the background is shown the long line of arches of the Basilica Julia, with (on the left) what is probably the temple of Castor and the arch of Augustus. On the right are the statue of Marsyas and the sacred fig-tree. 7 On the other slab a crowd of officials are bringing tablets and piling them in a heap to be burnt. This records the remission by Trajan of some arrears of debt due to the imperial treasury (Auspn. Grot. Act. 32). The background bere represents again the Basilica Julia, with (on the right) the Ionic :emple of Saturn and the Corinthian temple of Vespasian. Between them is an arch, which may be that of Tiberius. 8 On the left the jraecostasi, quae tune supra Comitium erat." Both these were Drobably only small shrines. 6 Twelve gilt statues are mentioned by Varro.

7 This is not the ficus ruminalis in the Comitium, but another mentioned by Pliny (H.N. xv. 20) in the middle of the Forum.
8 As it seems to be on a higher level, it may indicate the Tabularium.
fig-tree and the statue of Marsyas are repeated. Other explanations of these reliefs have been given, but the above appears the most probable. Towards the other end of the Forum are remains of a large concrete pedestal. It may possibly have supported an equestrian statue of Constantino, which was still standing in the 8th century. A smaller foundation, laid bare by Comm. Boni's excavations in 1905, is thought by him to have supported the equestrian statue of Q. Marcius Tremulus, the conqueror of the Hernici, set up before the temple of Castor in B.C. 305 (Liv. ix. 43). % The seven cubical brick and concrete structures, once faced with marble, which line the Sacra Via are not earlier than the time of Diocletian. They are probably the pedestals of honorary columns such as those shown in the relief on Constantine's arch, mentioned above. The column erected in honour of the tyrant Phocas by Smaragdus in the eleventh year of his exarchate (608) is still standing. It is a fine marble Corinthian column, stolen from some earlier building; it stands on rude steps of marble and tufa. The name of Phocas is erased from the inscription ; but the date shows that this monument was to his honour. In the 4th century, or perhaps even later, a long brick and concrete building faced with marble was built along the whole south-east end of the Forum, probably a row of shops. They were destroyed by Comm. Rosa's order. Two columns one of pavonazzetto, the other of grey granite were set up on two of the brick bases in 1899.
In 1902 a network of passages (cuniculi) was discovered about 3 ft. beneath the pavement of the Forum. These have tufa walls and concrete vaults; they are about 8 ft. high and 5 ft. broad. At the intersections of the passages are square chambers, in the centre of which are travertine blocks with sockets for windlasses. The construction of the passages seems to date from the time of Julius Caesar, and it is thought that they were used for scenic purposes when games were given in the Forum.
In 1903 a large concrete foundation was found, partly blocking the E. end of one of the cuniculi. There can be no doubt that this once supported the colossal equestrian statue of Domitian described by Statius (Silv. i. I, 21 ff.) which was destroyed after his murder. Embedded in the concrete was a cist of massive travertine blocks which was found to contain five archaic vases similar to those from the early necropolis (above, as init.). One held a nugget of quartz containing pure gold. It is uncertain whether these were buried here for ritual purposes or were the contents of an early tomb found in digging the foundations. Near this monument there were found in 1904 remains of an enclosure of irregular shape which once contained an altar. This must have been the altar which in imperial times represented the Lacus Curtius (Ov. Fast. vi. 403). Beside this were found some remains of a structure of imperial date which Comm. Boni identified with the Tribunal at which justice was administered by the emperors. 1 Palatine Hill or Palatium.
In addition to the early walls described above, only a few remains now exist earlier in date than the later years of the republic; these are mostly grouped near the Scalae Caci (see fig. 10, in Plan), and consist of small cellae and other structures of unknown use. 2 They are partly built of the soft tufa used in the " wall of Romulus," and partly of hard granulated tufa so called. Various names, such as the " hut of Faustulus " and the " Auguratorium," have been given to these very ancient remains, but with little reason. On thing is certain, that the buildings were respected and preserved even under the empire, and were probably regarded as sacred relics of the earliest times.
1 Authorities on the Forum ; For the earlier literature of the subject it will suffice to refer to Jordan, Topographic der Stadt Rom, i. 2, 195-429, and, in English, to Nichols, The Roman Forum (1877). By far the best account based on the recent discoveries of Comm. Boni is Huelsen, The Roman Forum (Eng. trans, from the 2nd German edition, by J. B. Carter, 1906), in which full references are given. The official reports of excavations by Comm. Boni appear at intervals in the Notizie degli Scavi, and are largely concerned with the ancient necropolis. Huelsen publishes reports in the Romische Mitteilungen which are of great value.
2 Our knowledge of these remains has been considerably increased by excavations in this region begun in 1907, which form the subject of a series of reports in the Notizie degli Scavi ; their significance is discussed by Pinza in the Annali delta Societa degli ingegneri ed architetti Italiani for that year, cf. Ashby in Classical Quarterly (1908), p. 145 ff. It is almost too much to hope that the difficult problems raised by these discoveries will ever be solved ; meanwhile it may be noted (i) that abundant traces of a primitive settlement (pottery, foundations of huts, etc.) have come to light near the W. angle of the hill ; (ii) that walls of various epochs have been found which may have belonged to a system of fortification, though this cannot be demonstrated; (iii) that beneath a piece of walling built with regularly laid tufa blocks was found an inhumation-grave containing pottery of the 4th century B.C.
Remains of more than one temple of the republican period exist near this west angle of the Palatine. The larger of these (see Plan) has been called conjecturally the temple of Jupiter Victor (Liv. x. 29; Ov. fast. iv. 621).' It stands on a levelled Temple of platform of tufa rock, the lower part of which is excavated Jupiter into quarry chambers, used in later times as water Vktor. reservoirs. Two ancient well-shafts lined with tufa communicate with these subterranean hollows. Extensive foundations of hard tufa exist in the valley afterwards covered by the Flavian palace (see Plan, " Foundations of the Domus Augustana "). The masonry is in parts of republican date, and was used to support the Flavian palace. Not far from the top of the Scalae Caci are the masMvc remains of a large cella, nothing of which now exists except the concrete core faced with opus incertum in alternate layers of tufa and peperino. It was probably once lined with marble. By it a noble colossal seated figure of a goddess was found, in Greek marble, well modelled, a work of the 1st century A.D. The head and arms are missing, but the figure is probably rightly called a statue of Cybele; and inscriptions dedicated to Magna Mater have been found close to the temple. Augustus in the Monumentum Ancyranum (4, 8) records AKDLM. MATRIS.MAGNAE.IN.PALATIO.FECI; and there can be little doubt that this is the temple in question. Some interesting early architectural fragments are lying near this temple; they consist of drums and capitals of Corinthian columns, and part of the cornice of the pediment, cut in peperino, and thickly coated with hard white stucco to imitate marble. Between this and the temple of Jupiter Victor are extensive remains of a large porticus, with tufa walls and travertine piers, also republican in date. The use and name of this building are unknown.
Remains of extensive lines of buildings in early opus reticulatum exist on the upper slopes of the Palatine, all along the Velabrum side, and on the south-west side as far as the so-called Paedagogium. These buildings are constructed on the ruins of the wall of Romulus, a great part of which has been cut away to make room for them; their base is at the foot of the ancient wall, on the shelf cut midway in the side of the hill; their top reached originally above the upper level of the summit. They are of various dates, and cannot be identified with any known buildings. Part is apparently of the time of the emperor Tiberius, and no doubt belongs to the Dpmus Tiberiana mentioned by Suetonius (Tib. 5; Tac. Hist. i. 27, iii. 71) ; this palace covered a great part of the west corner of the hill. Of about the same date is a very interesting and well-preserved private house built wholly of opus House at reticulatum, which formed part of the imperial property, Uvla. and was respected when the later palaces were built. The discovery of lead-pipes bearing the inscription IVLIAE . AVQ (C.I.L. xv. 7264) has led to the conjecture that the house was that bequeathed to Livia by her first husband, Tib. Claudius Nero. At the north-west end is a small atrium, out of which open three rooms commonly called the tablinum and aloe, as well as a triclinium, all decorated with good paintings of mythological and domestic scenes, probably the work of Greek artists, as inscriptions in Greek occur, e.g. EPMHC, under the figure of Hermes, in a picture representing his deliverance of lo from Argus. 4 This suite of rooms was a later addition to the house. The south-east portion was three storeys high, and is divided into a great number of very small rooms, mostly bedrooms. The house is built in a sort of hole against the side of an elevation, so that the upper floor behind is level with an ancient paved road. The dampness caused by this is counteracted and kept off the paintings by a lining of flange-tiles over the external walls, under the stucco, thus forming an air-cavity all over the surface. From the back of the house, at the upper level, along subterranean passage leads towards the Flavian palace, and then, turning at right angles and passing by the foundations of the so-called temple of Jupiter Victor, issues in the ancient tufa building mentioned above. Another crypto-porticus starts near this house and communicates with the long semi-subterranean passage by which the palaces of Caligula and Domitian are connected. It is ornamented with very beautiful stucco reliefs of cupids, beasts and foliage, once painted and gilt. Some hold that the house was that of Germanicus, into which the soldiers who killed Caligula in the long crypto-porticus escaped, as described by Josephus (Ant. Jud. xix. i ; see also Suet. Col. 58).
From the Summa Sacra Via a road led to the Area Palatina in the centre of the hill. Here was the sanctuary called Roma quadrate, containing the mundus, a pit in which the instruments used in the founding of the city were deposited. To the east was the Area Apollinis, the entrance of which led through lofty propylaea into a very extensive peristyle 'L w ai or porticus, with columns of Numidian giallo; the temple ' was of white Luna marble. In the centre of this enclosure stood the great octostyle peripteral temple of Apollo Palatinus. The splendour of its architecture and the countless works of art in gold, 8 It has recently been argued by Pinza that this is the temple of Apollo built by Augustus.

silver, ivory, bronze and marble, mostly the production of the best Greek artists, which adorned this magnificent group of buildings, must have made it the chief glory of this splendid city. This temple was begun by Augustus in 36 B.C.,' after his Sicilian victory over Sextus Pompeius, and dedicated on the 9th of October 28 B.C. 1 A glowing account of the splendours of these buildings is given by Propertius (ii. 2, iii. 31). Inside the cella were statues of Apollo between Latona and Diana by Scopas, Cephisodotus and Timotheus respectively (Plin. H.N. xxxvi. 24, 25, 32); beneath the base of the group were preserved the Sibylline books. The pediment had sculpture by Bupalus and Archermus of Chios (Plin. H.N. xxxvi. 13), and on the apex was Apollo in a quadriga of gilt bronze. The double door was covered with ivory reliefs of the death of the Niobids and the defeat of the Gauls at Delphi. The Ancyran inscription records that Augustus melted down eighty silver statues of himself and with the money " offered golden gifts " to this temple, dedicating them both in his own name and in the names of the original donors of the statues. 3 The Sibylline books were preserved under the statue of Apollo (Suet. Aug. 31); and within the cella were vases, tripods and statues of gold and silver, with a collection of engraved gems dedicated by Marcellus (see Plin. H.N. xxxvii. n, xxxiv. 14). In the porticus was a large library, with separate departments for Latin and Greek literature, 4 and a large hall where the senate occasionally met (Tac. Ann. ii. 37). Round the porticus, between the Numidian marble columns, were statues of the fifty Danaids, and opposite them their fifty bridegrooms on horseback (see Schol. on Pers. ii. 56). In the centre, before the steps of the temple, stood an altar surrounded by four oxen, the work of Myron (Prop. iii. 31, 5). In the centre of the Palatine stood the palace of Augustus, built in the years following 36 B.C., and renewed after a fire in A.D. 3. It contained a small temple of Vesta (C.I.L. i? p. 317), dedicated on the 28th of April 12 B.C., when Augustus was elected pontifex maximus. Augustus's building was completely transformed by later emperors, but the name domus Augustana was retained in official use. The Area Apollinis and its group of buildings suffered in the fire of Nero, and were restored by Domitian. The whole was finally destroyed in the great fire of 363 (Ammian. xxiii. 3, 3), but the Sibylline books were saved.
To the north-west of the Area Palatina stood the Domus Tiberiana, a palace built by Tiberius on substructures of concrete which crown the north-west slope of the hill and form a platform now occupied Tlbert ky *^ e Farnese gardens, overlooking the Clivus Victoriae.
Caligula is said to have added to this palace on the side towards the Forum, making the temple of Castor into a vestibule, and to have connected it with the Capitol by a bridge whose piers were found by the temple of Augustus and the Basilica Julia; but this was destroyed after his death. At a later time the palace was extended so as to include the northern angle of the Palatine, which had once been covered with private houses. Among these were the dwellings of Q. Lutatius Catulus, Q. Hortensius, Scaurus, Crassus (Plin. H.N. xxxvi. 3, 24), whose house was afterwards bought by Cicero. 6 Many other wealthy Romans had houses on this part of the Palatine. The part now existing is little more than the gigantic substructure built to raise the principal rooms to the level of the top of the hill. The lowest parts of these face the Nova Via, opposite the Atrium Vestae, and many storeys of small vaulted rooms built in mixed brick and opus reticulatum rise one above the other to the higher levels. 6 The palace extends over the Clivus Victoriae, supported on lofty arches so as to leave the road unblocked ; many travertine or marble stairs lead to the upper rooms, some starting from the Nova Via, others from the Clivus Victoriae. A large proportion of these substructures consist of dark rooms, some with no means ,of lighting, others with scanty borrowed light. Many small rooms and stairs scarcely 2 ft. wide can only have been used by' slaves. The ground floors on the Nova Via and the Clivus Victoriae appear to have been shops, judging from their wide openings, with travertine sills, grooved for the wooden fronts with narrow doors, which Roman shops seem always to have had very like those now used in the East. The upper and principal rooms were once richly decorated with marble linings, columns and mosaics; but little of these now remains. The upper part of the palace, that above the Clivus Victoriae, is faced wholly with brickwork, no opus reticulatum being used as in the lower portions by the Nova Via. This marks a difference of date, and this is confirmed by the occurrence of brick stamps of the 2nd century A.D.

6 At this point the Palatine is cut away into four stages like gigantic steps; the lowest is the floor of the Atrium Vestae, the second the Nova Via, the third the Clivus Victoriae, and the top of the hill forms the fourth.
The next great addition to the buildings of the Palatine was the magnificent suite of state apartments built by Domitian, over a deep natural valley running across the hill (see Plan). The valley was filled up and the level of the new palace . raised to a considerable height above the natural soil. '* Remains of a house, decorated with painting and rich marbles, exist under Domitian's peristyle, partly destroyed by the foundations of cast concrete which cut right through it. The floor of this house shows the original level, far below that of the Flavian palace. This building is connected with the palace of Caligula by a brandi subterranean passage leading into the earlier crypto-porticus. It consists of a block of state-rooms, in the centre of which is a large open peristyle, with columns of oriental marble, at one end of which is the grand triclinium with magnificent paving of opus sectile in red and green basalt and coloured marbles, a piece of which is well preserved; next to the triclinium, on to which it opens with large windows, is a nymphaeum or room with marble-lined fountain and recesses for plants and statues. On the opposite side of the peristyle is a large throne-room, the walls of which were adorned with rows of pavonazzetto and giallo columns and large marble niches, in which were colossal statues of porphyry and basalt; at one side of this is the basilica, with central nave and apse and narrow aisles, over which were galleries. The apse, in which was the emperor's throne, is screened off by open marble cancelli, a part of which still exists. It is of great interest as showing the origin of the Christian basilica (see BASILICA). 7 On the other side of the throne-room is the lararium, with altar and pedestal for a statue; next to this is the grand staircase, which led to the upper rooms, now destroyed. The whole building, both floor and walls, was covered with the richest oriental marbles. Outside were colonnades or porticus, on one side of cipollino, on the other of travertine, the latter stuccoed and painted. The magnificence of the whole, crowded with fine Greek sculpture and covered with polished marbles of the most brilliant colours, is difficult now to realize; a glowing description is given by Statius (Silv. iv. II, 18; see also Plut. Poplic. 15, and Mart. viii. 36). Doors were arranged in the throne-room and basilica so that the emperor could slip out unobserved and reach by a staircase (g on Plan) the crypto-porticus which communicates with Caligula's palace. The vault of this passage was covered with mosaic of mixed marble and glass, a few fragments of which still remain; its walls were lined with rich marbles; it was lighted by a series of windows in the springing of the vault. This, as well as the Flavian palace, appears to have suffered more than once from fire, and in many places important restorations of the time of Severus, and some as late as the 4th century, are evident. In 1720-28 extensive excavations were made here for the Farnese duke of Parma, and an immense quantity of statues and marble architectural fragments were discovered, many of which are now at Naples and elsewhere. Among them were sixteen beautiful fluted columns of pavonazzetto and giallo, fragments of the basalt statues, and an immense door-sill of Pentelic marble, now used for the high altar of the Pantheon ; these all came from the throne-room. The excavations were carried on by Bianchini, who published a book on the subject. 8 In the middle of the slopes of the Palatine, towards the Circus Maximus, are considerable remains of buildings set against the early wall and covering one of its projecting spurs, consisting in a series of rooms with a long Corinthian colonnade. The rooms were partly marble-lined and partly decorated with painted stucco, on which are incised a number of interesting inscriptions and rude drawings. Here, in 1856, was found the celebrated caricature of the Crucified Christ, now in the Museo Kircheriano. 9 The inscription CORINTHVS . EXIT . DE . PEDAGOGIC suggests that this building was at one time used as a school, perhaps for the imperial slaves. 10 A number of soldiers' names also occur, e.$. HILARYS . MI . V . D . N . (Hilarus miles vestitor domini nostri ?) ; some are in mixed Latin and Greek characters. After one pair of names is inscribed PEREG, showing that they belonged to the corps called frumentarii stationed in the Castra Peregrinorum on the Caelian. Most of these inscriptions appear to be as early as the 1st century A.D. " These interesting graffiti have in great part perished during the last few years. Some inscriptions found in the larger rooms seem to indicate that the imperial wardrobe found a place in them.
To the south of the Flavian state-rooms, on the side of the hill overlooking the Circus, was a building with a central peristyle (" Palace of Domitian " on Plan), which was excavated in 1775 and 7 The brick stamps on the tiles laid under the marble paving of the basilica have CN.DOMITI.AMANDI.

again partly laid bare in 1869 and the following years. This has often, but wrongly, been called the palace of Augustus; we should rather see in it the dwelling-rooms of the Flavian palace. Adjoining it is the so-called stadium of the Palatine (" Hippodromus" on Plan), begun by Domitian, enlarged by Hadrian, and much altered or restored by Severus. The greater part of the outer walls and the large exedra or apse at the side, with upper floor for the emperor's seat, are of the time of Hadrian, as is shown by the brick stamps, and the character of the brick facing, which much resembles that of the Flavian time (bricks ij in. and joints J in. thick). 1 The stadium is surrounded with a colonnade of engaged shafts, forming a sort of aisle with gallery over it. Except those at the curved end, which are of Hadrian's time, these piers are of the time of Severus, as are also all the flat piers along the outer wall, one opposite each of those in the inner line. Severus restored the galleries after the great fire of A.D. 191. This building was the hippodromus Palalii; the word here means, not a racecourse, but a garden (Plin. Epp. 5, 6, 19). In addition to the stadium, Hadrian built a number of very 1 In parts of the outer wall brick stamps of the Flavian period appear, e.g. FLAVI AVQ.L.CLONI " [A brick] of Flavius Clonus, freedman of Augustus" (C.I.L. xv. 1149).
handsome rooms, forming a palace on the south-east side and at the south-west end of the stadium. These rooms were partly destroyed and partly hidden by the later palace of Severus, the Hadrian'* foundations of which in many places cut through and palate. render useless the highly decorated rooms of Hadrian. The finest of these which is now visible is a room with a large window opening into the stadium near the south angle; it has intersecting barrel vaults, with deep coffers, richly ornamented in stucco. The oval structure shown in the plan (fig. 10), with other still later additions, belongs to the 6th century ; in its walls, of opus mixtum, are found brick stamps of the reign of Theodoric, c. 500.
The palace of Septimius Severus was very extensive and of enormous height; it extends not only all over the south angle of the Palatine but also a long way into the valley of the Circus P^KC o/ Maximus and towards the Coelian. This part (like Stvtm*. Caligula's palace) is carried on very lofty arched substructures, so as to form a level, uniform with the top of the hill, on which the grand apartments stood. The whole hejght from the base of the Palatine to several storeys above its summit must have been enormous. Little now remains of the highest storeys, except part of a grand staircase which led to them. Extensive baths, originally decorated with marble linings and mosaics in glass and marble, cover a great part of the top of the hill. These and other parts of the Palatine were supplied with water by an aqueduct built by Nero in continuation of the Claudian aqueduct, some arches of which still exist on the slope of the Palatine (" Aqtla Claudia" on Plan) (see Spart. Sept. Sev. 24). One of the main roads up to the Palatine passes under the arched substructures of Severus, and near this, at the foot of the hill, at the south angle, Septimius Severus built an outlying part of his palace, a building of great splendour called the Septizodium, 1 or House of the Seven Planets. Part of the Septizodium existed as late ^s the reign of Sixtus V. (1585-90), who destroyed it in order to use its marble decorations and columns in the new basilica of St Peter; drawings of it are given by Du Pe>ac, Vestigj di Roma (1575), pi. 13, and in other works of that century. 2 The name Palatium seems to have originally denoted the sou them height of the Palatine hill, while the summit overlooking the Vela- brum was called Cermalus, and the saddle connecting the e a an Palatine and the Esquiline on which the temple of Venus Cermalus. an( j R ome anc j (. ne ar ^ n o f Xitus now stand bore the name Velia.* It is evident that this was once higher than it is now; a great part of it was cut away when the level platform for the temple of Venus and Rome was formed. The foundations of part of Nero's palace along the road between this temple and the Esquiline are exposed for about 20 to 30 ft. in height, showing a corresponding lowering of the level here, and the bare tufa rock, cut to a flat surface, is visible on the site of Hadrian's great temple; that the Velia was once much joftier is also indicated by the story of the removal of Valerius Publicola's dwelling. 4 The arch of Titus, erected in memory of that emperor's subjugation of the Jews, but not completed until after his death, stands at the pcint where the Sacra Via crosses the Velia ; it is possible that it once stood farther to the east and was removed to its present position when the temple of Venus and Rome was built. The well-known reliefs of the archway depict the Jewish triumph and the spoils of the Temple. In the middle ages the arch was converted into a fortress by the Frangipani ; their additions were removed and the arch restored in its present shape in 1821.
On the Velia and the adjoining Summa Sacra Via were the temples of the Lares and Penates which Augustus rebuilt. 6 The " Aedes Sacra Larum " is probably distinct from the " Sacellum Lamm " V4j mentioned by Tacitus (Ann. xii. 24) as one of the points in the line of the original pomerium. The temple of Jupiter Stator, traditionally vowed by Romulus during his repulse Temple of ^ tne Sabines (Liv. i. 12), stood near the Porta Mugonia, Jupiter anc * tne r e f r e near the road leading up to the Palatine Stator. Sacra Via. 6 To the south-east of the arch of Titus (see Plan) are the remains of a concrete podium which may have belonged to this temple in its latest form; and Comm. Boni discovered (in 1907) some early tufa walling close to the abovenamed arch in which he recognized the foundations of the earlv Temple of tem P'. e - Augustus rebuilt the temple of Vicjory, which Victory gave its name to the Clivus Victoriae; this temple stood on the site of a prehistoric altar (Dionys. i. 32), and was more than once rebuilt, e.g. by L. Postumius, 294 B.C. (Liv. x. 33). In 193 B.C. an aedicula to Victory was built near it by M. Porcius Cato (Liv. xxxv. 9). Remains of the temple and a dedicatory inscription were found in 1728' not far from the church of S. Teodoro; the temple was of Parian marble, with Corinthian columns of Numidian giallo antico. The Sacra Via started at the Sacellum Streniae, an unknown point on the Esquiline, probably in the valley of the Colosseum (Varro, L.L. v. 47), in the quarter called Cerolia. Thence it probably (in later times) passed round part of the Colosseum to the slope leading up to the arch of Titus on the Velia ; this piece of its course is lined on one side by remains of private houses, and farther back, against the cliff of the Palatine, are the substructures of the Area Apollinis. From the arch of Titus or Summa Sacra Via the original line of the road has been altered, probably when the temple of Venus and Rome was built by Hadrian. Its later course passed at a sharp angle from the arch 1 The form Septizonium is also found.

Owing to the strength of its position this temple was more than once selected during troubled times as a safe meeting-place for the Senate; it was here, as being a " locus munitissimus," that Cicero delivered his First Catiline Oration (see Cic, In Cat. i. i).

of Titus to the front of Constantino's basilica, and on past the temple of Faustina. It is uncertain whether the continuation of this road to the arch of Severus was in later times called the Sacra Via or whether it rejoined its old line along the Basilica Julia by the cross-road in front of the Aedes Julii. Its original line past the temple of Vesta was completely built over in the 3rd and /j.th centuries, and clumsily fitted pavements of marble and travertine occupy the place of the old basalt blocks. 8 The course of the Nova Via' (see Plan) along the north-east slope of the Palatine 10 was exposed in 1882-84. According to Varro (L.L. vi. 50) it was a very old road. It led up from the Velabrum, probably winding along the slope of the Palatine, round the north angle above the church of S. Maria Antiqua. The rest of its course, gently ascending towards the arch of Titus, is now exposed, as are also the stairs which connected it with the Clivus Victoriae at the northern angle of the Palatine; a continuation of these stairs led down to the Forum."
The extent of the once marshy Velabrum (Gr. F Xos) is not known, though part of its site is indicated by the church of S. Giorgio in Velabro; Varro (L.L. vi. 24) says, " extra urbem antiquam v I - f uit, non longe a porta Romanula." It was a district full of shops (Plaut. Capt. 489; Hor. Sat. ii. 3, 30). The Vicus Tuscus on its course from the Forum to the Circus skirted the Velabrum (Dionys. v. 26), from which the goldsmiths' arch was an entrance into the Forum Boarium.
From the S.W. end of the Velabrum the Clivus Victoriae rose in a gradual ascent along the slope of the Palatine and ultimately wound round the northern angle.
Capitoline Hill 12 The Capitoline hill, once called Mons Saturnius (Varro, L.L. v. 42), consists of two peaks, the Capitolium and the Arx, 13 with an intermediate valley (Asylum). The older name of the Capitolium was Mons Tarpeius (Varro, L.L. v. 41). Livy (i. 10) mentions the founding of a shrine to Jupiter Feretrius on the Capitolium by Romulus; 14 this summit was afterwards occupied by the great triple temple dedicated to Jupiter, Juno Temple of and Minerva, a triad of deities worshipped under the Jupiter names of Tinia, Thalna and Menerva in every Etruscan Cap Halcity. This great temple was (Liv. i. 38, 53) founded to " s " by Tarquin I., built by his son Tarquin II., and dedicated by M. Horatius Pulvillus, consul suffectus in 509 B.C. U It was built in the Etruscan style, of peperino stuccoed and painted (Vitr. iii. 3), with' wooden architraves, wide intercolumniations and painted terra-cotta statues. 16 It was rebuilt many times; the original temple lasted till it was burnt in 83 B.C.; it was then refounded in marble by Sulla, with Corinthian columns stolen from the temple of Olympian Zeus in Athens (Plin. xxxvi. 4, 5), and was completed and dedicated by Q. Lutatius Catulus, whose name appeared on the front. Augustus, although he restored it at great expense (Man. Anc. 4, 9), did not introduce his name by the side of that of Catulus. It was again burnt by the Vitellian rioters in A.D. 70, and rebuilt by Vespasian in 7 1. 17 Lastly, it was burnt in the three days' fire of Titus's reign 18 and rebuilt with columns of Pentelic marble by Domitian ; the gilding alone of this last rebuilding is said to have cost 2^ millions sterling (Plut. Publ. 15). Extensive substructures of tufa have been exposed on the eastern peak; in 1875 a fragment of a fluted column was found, of such great size that it could only have belonged to the temple of Jupiter; and a few other architectural fragments have been discovered at different times. The western limit of the temple was determined in 1865, its eastern limit in 1875, and the S.E. angle in 1896.

It appears that the figures given by Dionysius (iv. 61) for the area are slightly too large. The true measurements were 1 88 X 204 Roman ft. 1 The temple is represented on many coins, both republican and imperial; these show that the central cella was that of Jupiter, that of Minerva on his right and of Juno on his left. The door was covered with gold reliefs, which were stolen by Stilicho (c. 400; Zosim. v. 38), and the gilt bronze tiles (cf. Plin. xxxiii. 57) on the roof were partly stripped off by Geiseric in 455 (Procop. Bell. Vand. i. 5), and the rest by Pope Honorius I. in 630 (Marliani, Topogr. ii. i). 2 Till 1348, when the steps up to Ara Coeli were built, there was no access to the Capitol from the back; hence the three ascents to it mentioned by Livy (iii. 7, v. 26-28) and Tacitus (Hist. iii. 71-72) were all from the inside of the Servian circuit. Even on this inner side it was defended by a wall, the gates in which are called " Capitolii fores " by Tacitus. Part of the outer wall at the top of the tufa rock, which is cut into a smooth cliff, is visible from the modern Vicolo della Rupe Tarpeia; this cliff is traditionally called the Tarpeian rock, but that must have been on the other side towards the Forum, from whence it was visible, as is clearly stated by Dionysius (vii. 35, viii. 78).' Another piece of the ancient wall has been exposed, about half-way up the slope from the Forum to the Arx. It is built of soft yellow tufa blocks, five courses of which still remain in the existing fragment. The large temple of Juno Moneta (" the Adviser ") on the Arx, built by Camillus in 384 B.C., was used as the mint; hence monela= " money " (Liv. vi. 20).
A large number of other temples and smaller shrines stood on the Capitoline hill.'a word used broadly to include both the Capitolium and the Arx. 4 Among these were the temple of Honos and Virtus, built by Marius,-and the temple of Fides, founded by Numa, and rebuilt during the First Punic war. Both these were large enough to hold meetings of the senate. The temples of Mars Ultor (Man. Anc. 4, 5) and Jupiter Tonans (Suet. Aug. 29; Man. Anc. 4, 3) were built by Augustus. Other shrines existed to Venus Victnx Ops, Jupiter Gustos, and Concord the last under the Arx (Liv. xxii. 33) and many others, as well as a triumphal arch in honour of Nero, and a crowd of statues and other works of art (see Plin. H.N. xxxiii. 9, xxxiv. 38, 39, 40, 43, 44, 79, xxxv. 69, ipo, 108, 157), so that the whole hill must have been a mass of architectural and artistic magnificence.
The so-called Tabularium 6 occupies the central part of the side towards the Forum; it is set on the tufa rock, which is cut away _ to receive its lower storey. It derives its name from an inscription which remained in situ until the 15th century ""' (C.I.L. vi. 1314); whilst all public departments had their tabularia, this was a central Record Office, where copies of laws, treaties, etc., were preserved. It was built by Catulus, who was also the dedicator of the great temple of Jupiter (Tac. Hist. iii. 72; Dio Cass. xliii. 14), consul in 78 B.C. Its outer .walls are of sperone, its inner ones of tufa; the Doric arcade has capitals, imposts and entablature of travertine. Above the arcade was a gallery or porticus, faced with a Corinthian colonnade, of which a few architectural members have been found. The columns appear to have belonged to the 1st century A.D. A road paved with basalt passes through the building along this arcade, entered at one end from the Clivus Capitolinus, and at the other probably from the Gradus Monetae, a flight of steps leading from the temple of Concord and the Forum up to the temple of Juno Moneta on the Arx. The entrance from the Clivus Capitolinus is by a wide flat arch of peperino beautifully jointed; the other end wall has been mostly destroyed. The back of this building overlooked the Asylum 1 See Bull. Comm. Arch. iii. (1875), p. 165; Man.

It has been recently proved to have decorated the Forum of Trajan (Wace in Papers of the B.S.R. iv. p. 240, pi. xx.). The front of the temple is shown on one of the reliefs of Marcus Aurelius now in the Palazzo dei Conservatori (Papers of the B.S.R. iii. pi. xx vi.).

or depression between the two peaks. From this higher level a long steep staircase of sixty-seven steps descends towards the Forum; the doorway at the foot of these stairs has a flat arch, with a circular relieving arch over it; it was blocked up by the temple of Vespasian. Great damage was done to this building by the additions of Boniface VIII. and Nicholas V., as well as by its being used as a salt store, by which the walls were much corroded. 8 The Imperial Fora.

II, Plan), with its central temple of Venus Genetrix, was begun, about 54 B.C., by Julius (who dedicated it in an unfinished state in 46 B.C.) and completed by forum Augustus. 7 Being built on a crowded site it was some- . .. what cramped, and the ground cost nearly a hundred million sesterces. 8 Part of its circuit wall, with remains of five arches, exists in the Via delle Marmorelle ; and behind is a row of small vaulted rooms, probably shops or offices. The arches are slightly cambered with travertine springers and keys; the rest, with the circular relieving arch over, is of tufa; it was once lined with slabs of marble, the holes for which exist. Foundations of the circuit wall exist under the houses towards S. Adriano, but the whole plan has not been made out. In the centre of the Forum stood the temple of Venus Genetrix, whose remains were seen and described by Palladio (Arch. iv. 31). This temple was vowed by Caesar at the battle of Pharsalus. 9 The forum of Augustus (see fig. n) adjoined that of Julius on its north-east side; it contained the temple of Mars Ultor, built to commemorate the vengeance taken on Caesar's murderers at Philippi; 42 B.C. (Oy. Fast, v. 575 seq.).' It was surrounded with a massive wall of peperino, over 100 ft. high, with travertine string-courses and cornice; a large piece of this wall still exists, and is one of the most imposing relics of ancient Rome. Against it are remains of the temple of Mars, three columns of which, with their entablature and marble ceiling of the peristyle, are still standing; it is Corinthian in style, very richly decorated, and built of fine Luna marble. The cella is of peperino, lined with marble; and the lower part of the lofty circuit wall seems also to have been lined with marble on the inside of the forum. The large archway by the temple (Arco dei Pantani) is of travertine. Palladio (Arch, iv.) and other writers of the 16th century give plans of the temple and circuit wall, showing much more than now exists. The temple, which was octastyle, with nine columns and a pilaster on the sides, occupied the centre, and on each side the circuit wall formed two large semicircular apses, decorated with tiers of niches for statues. 11 The Forum Pacis, built by Vespasian, was farther to the southeast; the only existing piece, a massive and lofty wall of mixed tufa and peperino, with a travertine archway, is opposite _ the end of the basilica of Constantine. The arch opened into the so-called Templum Sacrae Urbis, a rectangular building entered by a portico on its west side, whose north wall was decorated with a marble plan of the city of Rome (see below, p. 608). The original plan was probably burnt with the whole group of buildings in this forum in 191, in the reign of Commodus (Dio Cass. Ixxii. 24) ; but a new plan was made, and the building restored in concrete and brick by Severus. The north end wall, with the clamps for fixing the marble plan, still exists, as does also the other (restored) end wall with its arched windows towards the forum ; one hundred and sixty-seven fragments of this plan were found c. 1563 at the foot of the wall to which they were fixed, and are now preserved in the Capitoline Museum; drawings of seventy-four pieces now lost are preserved in the Vatican 12 (Cod. Vat. 3439). The whole of these fragments were published by Jordan, Forma Urbis Romae (Berlin, 1874). Other fragments have since been brought to light, and the whole series was rearranged in the Palazzo dei Conservatori in 1903. The circular building at the end facing on the Sacra Via is an addition built by Maxentius in honour of his deified son Romulus; like the other buildings of Maxentius, it was rededicated and inscribed with the name of his conqueror 6 The Porta Pandana (" ever-open gate ") gave access from the Area Capitolina, upon which the temple of Jupiter stood, to the Tarpeian rock.

Constantino. 1 The original building of Vespasian was probably an archive and record office; it was certainly not a temple. The fine bronze doors at the entrance to the temple of Romulus are much earlier than the building itself, as are also the porphyry columns and very rich entablature which ornament this doorway. Pope Felix IV. (526-30) made the double building into the church of SS. Cosmo e Damiano, using the circular domed temple of Romulus as a porch. 2 The chief building of Vespasian's forum was the Ternplum Pacis, 3 dedicated in 75, one of the most magnificent in Rome, which contained a very large collection of works of art.
The forum of Nerva (see fig. n) occupied the narrow strip left between the fora of Augustus and Vespasian; being little more than a richly decorated street, it was called the Forum Fon/m of fransitorium or Forum Palladium, from the temple to Minerva which it contained. It was begun by Domitian, and dedicated by Nerva in 97 (see Suet. Dom. 5; Mart. i. 2, 8). Like the other imperial fora, it was surrounded by a peperino wall, not only lined with marble but also decorated with rows of Corinthian columns supporting a rich entablature with sculptured frieze. Two columns and part of this wall still exist; on the frieze are reliefs of weaving, fulling and various arts which were under the protection of Minerva. A great part of the temple existed till the time of Paul V., who in 1606 destroyed it to use the remains for the building of the Acqua Paola.' In the reign of Scverus Alexander a series of colossal bronze statues, some equestrian, were set round this forum; they represented all the previous emperors who had been deified, and by each was a bronze column inscribed with his res gestae (Hist. Aug.; Sev. Alex. 28).
The forum of Trajan with its adjacent buildings was the last and, at least in size, the most magnificent of all ; it was in progress from 1 13 to 1 17, at least. A great spur of hill, which connected the Capitoline with the Quirinal, was cut away to make a irajaa. level site for this enormous group of buildings. It consisted (see fig. n) of a large dipteral peristyle, with curved projections, lined with shops on the side. That against the slope of the Quirinal, three storeys high, still partly exists. The main entrance was through a triumphal arch (Dio Cass. Ixviii. 29). Aurei of Trajan show this arch and other parts of his forum. 6 The opposite side was occupied by the Basilica Ulpia (Jordan, F. U.R. iii. 25, 26), part of which, with the column of Trajan, is now visible; none of the columns, which are of grey granite, are in situ, and the whole restoration is misleading. Part of the rich paving in oriental marble is genuine. This basilica contained two large libraries (Dio Cass. Ixviii. 16; Aul. Cell. xi. 17).

The Columna Cochlis (so caned trom its spiral stairs) is, including capital and base, 97 ft 9 in. high,' i.e. lop Roman ft.; its pedestal has reliefs of trophies of Dacian arms, and winged Victories. fralan'M On the shaft are reliefs arranged spirally in twenty-three co i um a. tiers scenes of Trajan's victories, containing about 2500 figures. Trajan's ashes were buried in a gold urn under this column (Dio Cass. Ixviii. 16); and on the summit was a colossal gilt bronze statue of the emperor, now replaced by a poor figure of St Peter, set there by Sixtus V.' Beyond the column stood the temple of Trajan completed by Hadrian; its foundations exist under the buildings at the north-east side of the modern f em nj e o / piazza, and many of its granite columns have been found, fralao. This temple is shown on coins of Hadrian. 8 The architect of this magnificent group of buildings was Apollodorus of Damascus (Dip Cass. Ixix. 4), who also designed many buildings in Rome during Hadrian's reign. 9 In addition to the five imperial fora, and the Forum Magnum, Holitorium and Boarium, mentioned above, there were also smaller markets for pigs (Forum Suarium), bread (Forum Pistorium) and fish (Forum Piscarium), all of which, with some others, popularly but wrongly called fora, are given in the regionary catalogues.
Other Temples, etc.
Besides the temples mentioned in previous sections remains of many others still exist in Rome. The circular temple by the Tiber, in the Forum Boarium (Plan, No. 5), formerly thought to be that of Vesta, is possibly that of Portunus, the god of the harbour (Varro, L.L. vi. 19). Its design is similar to that of the temple of Vesta in the forum (fig. 8), and, except the entablature and upper part of the cella, which are gone, it is well Other temples.
6 Its pedestal is inscribed, " Senatus Populusque Romanus Imp. Caesari Divi Nervae F. Nervae Trajano Aug. Germ. Dacico Pontif. Maximo Trib. Pot. XVII. [i.e. A.D. 113] Imp. VI. Cos. VI. P. P. ad dcclarandum quantae altitudinis mons et locus tantis operibus sit egestus." This would seem to indicate the height of the hill removed to form the site, and is so explained by Dion Cass. (Ixviii. 16). It is impossible that the saddle connecting the Quirinal with the Capitoline hill can have been too ft. in height (Brocchi, Suolo di Roma, p. 133), but it may be that the cliff of the Quirinal was cut back to a slope reaching to a point about 72 ft. high ; thus the statement of the inscription is much exaggerated. Comm. Boni has found the remains of a road beneath the pavement of the Forum, near the column, and believes that the inscription refers to the height of the buildings. Comparetti refers mons to the mass of marble quarried to build the Forum; Sogliano to the mass of ruins and rubbish carted away; Mau to the Servian agger between the Capitol and Quirinal (see Rom. Mitth., 1907, 187 ff.).

preserved. It may date from the 2nd century B.C. The neighbouring Ionic temple, popularly called of Fortuna Virilis, is of special interest from its early date, probably the end of the 3rd century B.C. The complete absence of marble and the very sparing use of travertine, combined with the simple purity of its design, indicate an early date. 1 It has a prostyle tetrastyle portico of travertine, and a short cella of tufa with engaged columns; the bases of these and of the angle columns are of travertine. The frieze has reliefs of ox skulls and garlands. The whole was originally stuccoed and painted so that the different stones used would not show. Fig. 12 gives the plan, showing the hard travertine used at the points of greatest pressure, while the main walls with the half columns are of the weaker and U softer tufa. The dedication of this temple is doubtful; but it is probably either that of Fortuna or of Mater Matuta, both of which were destroyed by fire in 213 B.C. and re- FIG. i2.-So-called Temple of Fortuna Virilis. red in the folThe black shows tufa; the shading travertine.
in Cosmedin contains some remains of a temple (Plan, No. 4) which has been identified with that of Hercules built by Pompey ad Circum Maximum (Vitr. iii. 2, 5; Plin. H.N. xxxiv. 57). The temple stands close to the carceres of the Circus Maximus, in the Forum Boarium. The columns built up in the church did not, however, belong to a temple, but to a pprticus. Within the walls of S. Niccolo in Carcere in the Forum Holitorium (Plan, No. 1 8) are preserved remains of three small hexastyle peripteral temples, two Ionic and one Tuscan, set close side by side. 2 A fragment of the marble plan includes part of this group. The Tuscan temple is built of travertine, the others of tufa and peperino, with travertine at the points of greatest pressure. They are probably those of Janus ad Theairum Marcelli, dedicated by C. Duilius in the First Punic War (Tac. Ann. ii. 49); of Spes, built by A. Atilius Calatinus, of about the same date (Tac. Ann. ii. 49); and of Juno Sospita, dedicated by C. Cornelius Cethegus in 197 B.C. (Liv. xxxiv. 53). Near the Forum Holitorium are extensive remains of the large group of buildings included in the Porticus Octaviae (Plan, No. 16), two of which, dedicated to Juno Regina and Jupiter Stator, with part o f the enclosing porticus and the adjoining temple of Hercules Musarum, are shown on a fragment of the marble plan. The Porticus Octaviae, a large rectangular space enclosed by a double line of columns, was built in honour of Octavia by her brother Augustus on the site of the Porticus Metelli, founded in 146 B.C. This must not be confounded with the neighbouring Porticus Octavia founded by Cn. Octavius, the conqueror of Perseus (Liv. xlv. 6, 42), in 168 B.C., and rebuilt under the same name by Augustus, as is recorded in the Ancyran inscription. The whole group was one of the most magnificent in Rome, and contained a large number of works of art by Pheidias and other Greek sculptors. The existing portico, which was the main entrance into the porticus, is a restoration of the time of Severus in 203. The church of S. Angelo in Pescheria and the houses behind it conceal extensive remains of the porticus and its temples (see Ann, Inst., 1861, p. 241, 1868, p. 108; and Contigliozzi, /. Portici di Ottavia, 1861).* Remains of a large peripteral Corinthian temple are built into the side of the Borsa (formerly the Custom House). Eleven marble columns and their rich entablature are still in situ, with the corresponding part of the cella wall of peperino; in 1878 a piece of the end wall of the cella was discovered, and, under the houses near, part of a large peri- bolus wall, also of peperino, forming an enclosure with columns all round the temple nearly 330 ft. square (see Bull. Comtn. Arch.
Rom. vi. pi. iv., 1878). This temple has commonly been identified with that of Neptune (Dio Cass. Ixvi. 24), built by Agrippa, and surrounded by the Porticus Argonautarum (Dio Cass. liii. 27; Mart. iii. 20, Ii); but it clearly dates, at least in its present form, from the 2nd century A.D., and is not improbably the temple of Hadrian, mentioned in the Notitia as being near this spot.
The temple of Venus and Rome on the Velia (see fig. 8) was the _ . . largest in Rome; it was pseudo-dipteral, with ten Corinlemnieot t j,; an co i umns o f Greek marble at the ends, and probRomc ' a b'y twenty at the sides; it had an outer colonnade round the peribolus of about 180 columns of polished granite. Of these only a few fragments now exist ; for several centuries 1 Fiechter (Rom. Mitth., 1906, pp. 220 ff.) has endeavoured to show that the temple in its present form dates from the 1st century B.C.
2 For drawings of them, see the list given by Huelsen in Jordan, Topographic, i. 3, 511, note II.
1 The remains of the Porticus Octaviae have been more completely exposed by the demolition of the Ghetto.
the whole area of this building was used as a quarry, while the residue of the marble was burnt into lime on the spot in kilns built of broken fragments of the porphyry columns. A considerable part of the two cellae with their apses, set back to back, still exists; in each apse was a colossal seated figure of the deity, and along the side walls of the cellae were rows of porphyry columns and statues in niches. The vault is deeply coffered with stucco enrichments once painted and gilt. The roof was covered with tiles of gilt bronze, which were taken by Pope Honorius I. (625-38) to cover the basilica of St Peter's. These were stolen by the Saracens during their sack of the Leonine city in 846. The emperor Hadrian himself designed this magnificent temple, which was partially completed in 135; the design was criticized severely by the architect Apollodorus (Dio Cass. Ixix. 4; Vita Hadr. 19). The temple was probably finished by Antoninus Pius; it was partly burned in the reign of Maxentius, who began its restoration, which was carried on by Constantine. The existing remains of the two cellae are mainly of Hadrian's time, but contain patches of the later restorations. Between the south angle of this temple and the arch of Constantine stand the remains of a fountain, usually known as the Meta Sudans. This was a tall conical structure in a large circular basin, all lined with marble. From its brick facing it appears to be a work of the Flavian period.
That part of the Caelian hill which is near the Colosseum is covered with very extensive remains a great peribolus of brickfaced concrete, apparently of Flavian date, and part of a BuUdlagt massive travertine arcade in two storeys, similar to that oa t fj e of the Colosseum; most of the latter has been removed caellaa, for the sake of the stone, but a portion still exists under Esqulllae the monastery and campanile of SS. Giovanni e Paolo. ant / There can be no reasonable doubt that these substruc- Qulrloal. tures carried the temple of Claudius, built by Vespasian (Suet. Vesp. 9).
The so-called temple of Minerva Medica (" Nympheum " on Plan) on the eastern slope of the Esquiline (so named fr.om a statue found in it), a curiously planned building, with central decagonal domed hall, probably belonged to the palace of Gallienus (263-68). Somewhat similar ruins beside the neighbouring basilica of S. Croce formed part of the Sessorium, a palace on the Esquiline. The remains on the Quirinal, in the Colonna gardens, of massive marble entablatures richly sculptured were formerly thought to belong to Aurelian's great temple of the Sun, but it now appears certain that they belong to the very extensive thermae of Constantine, part of the site of which is now occupied by the Quirinal palace and neighbouring buildings. 4 The excavations of recent years have brought to light, and in many cases destroyed, a large number of domestic buildings; these discoveries are recorded in the Notizie degli Scavi pri vate and the Bull. Comm. Arch. Rom. The extensive cutting bouses away of the Tiber bank for the new embankment exposed some very ornate houses near the Villa Farnesina, richly decorated with marble, fine wall-paintings, and stucco reliefs, equal in beauty to any works of the kind that have ever been found. These are now exhibited in the Museo delle Terme, but the houses themselves have been destroyed. The laying out of the new Quirinal and Esquiline quarters has also exposed many fine buildings. Some remains on the Esquiline have been supposed (without much probability) to belong to the villa of Maecenas. A very remarkable vaulted room, decorated with paintings of plants and landscapes, has been shown to be a greenhouse; 5 at one end is an apse with a series of step-like stages for flowers. This one room has been preserved, though the rest of the villa has been destroyed ; it is on the road leading from S. Maria Maggiore to the Lateran. The walls are a very fine specimen of tufa opus reticulatum, unmixed with brick, evidently of the early imperial period. Among the numerous buildings discovered in the Horti Sallustiani near the Quirinal was a very fine house of the 1st century A.D., in concrete faced with brick and opus reticulatum. It had a central circular domed hall, with many rooms and staircases round it, rising four storeys high. This house was set in the valley against a cliff of the Quirinal, so that the third floor is level with the upper part of the hill. It is nearly on the line of the Servian wall, which stood here at a higher level on the edge of the cliff. This park was laid out by the historian Sallust, and remained in the possession of his famijy until the reign of Tiberius, when it became imperial property; it was used as a residence by Nero (Tac. Ann. xiii. 47) and other emperors till the 4th century. 6 In 1884, near the Porta S. Lorenzo, a long line of houses was discovered during the making of a new road. Some of these were of opus reticulatum of the 1st century B.C.; others had the finest kind of 4 gee Palladio (Terme dei Romani, London, 1732), who gives the plan of this enormous building, now wholly hidden or destroyed.

The line of the street was parallel to that of the later Aurelian wall, which at this part was built against the back of this row of houses. At the same time, behind the line of houses were uncovered fine peperino and tufa piers of the aqueduct rebuilt by Augustus, one arch of which forms the Porta S. Lorenzo. These interesting remains have all been completely destroyed. A fine house of the end of the 1st century A.D., with richly decorated walls, was exposed in June 1884 against the slope of the Quirinal, near the Palazzo Colonna; it was immediately destroyed to make room for new buildings.
The praetorian camp was first made permanent and surrounded with a strong wall by the emperor Tiberius (Suet. Tib. 37). Owing .. to the camp being included in the line of the Aurelian wall, a great part of it still exists; it is a very interesting specimen of early imperial brick-facing. The wall is only 12 to 14 ft. high, and has thinly scattered battlements, at intervals of 20 ft. The north-east gate (Porta Principalis Dextra) is well preserved; it had a tower on each side, now greatly reduced in height, in which are small windows with arched heads moulded in one slab of terra-cotta. The brick-facing is very neat and regular, the bricks being about li in. thick, with i-in. joints. On the inside of the wall are rows of small rooms for the guards. Part of the Porta Praetoria also remains. This camp was dismantled by Constantine, who removed its inner walls; the outer ones were left because they formed part of the Aurelian circuit. The present wall is nearly three times the height of the original camp wall. The upper part was added when Aurelian included it in his general circuit wall round Rome. The superior neatness and beauty of Tiberius's brick- facing make it easy to distinguish where his work ends and that of the later emperors begins. Owing to the addition of the later wall it requires some care to trace the rows of battlements which belong to the camp.
The Pantheon is the most perfect among existing classical buildings in Rome. The inscription on the frieze of the portico (M . , . AGRIPPA . L . F . COS . TERTIVM . FECIT) refers to a build- ing erected by Agrippa in 27 B.C., consecrated to the divinities of the Julian house (Mars, Venus, etc.) under the name Pantheum (" all-holy "); cf. Dio Cass. liii. 27; Plin. H.N. xxxvi. 43. It was sometimes used as the meeting-place of the Fratres Arvales before they began to meet in the temple of Concord (C.I.L. v. 2041). Pliny mentions the sculpture by the Athenian Diogenes which adorned it, and its capitals and dome covering of Syracusan bronze (xxxiv. 7). It was long supposed that the present rotunda was the Pantheon of Agrippa; but this was destroyed in the great fire of A.D. 80 (Oros. 7, 12; Hieron. Abr. 2127); and recent investigations have shown that the rotunda is a work of Hadrian's reign, bricks of that period having been found in all parts of the building. Excavations have made it probable that the site of the rotunda was previously occupied by an open piazza, whose pavement of coloured marbles has been discovered beneath the flooring, and that Agrippa's Pantheon covered the present piazza and faced southward. The present portico has been reconstructed ; it is probable that Agrippa's portico had ten columns in the front. The ceiling of the portico too was of bronze, supported by hollow bronze girders, 1 which remained till Urban VIII. melted them to make cannon for S. Angelo; the bronze weighed 450,000 ft. The bronze tiles of the dome were stolen long before by Constans II., in 663, but on their way to Constantinople they were seized by the Saracens. The portico has eight columns on the front and three on the sides, all granite monoliths except the restored ones on the east side, sixteen in all. The capitals are Corinthian, of white marble; the tympanum (&tr6s) of the pediment was filled with bronze reliefs of the battle of the gods and the giants. 2 The walls of the circular part, nearly 20 ft. thick, are of solid tufa concrete, thinly faced with brick. The enormous dome, 142 ft. 6 in. in span, is cast in concrete made of pumice-stone, pozzolana and lime; being one solid mass, it covers the building like a shell, free from any lateral thrust at the haunches. On the face of the concrete is a system of superimposed relieving arches in brick. These no longer possess any constructive value, but were designed to preserve the stability of the dome whilst the concrete became firmly set. Round the central opening or hypaethrum still remains a ring of enriched mouldings in gilt bronze, the only bit left of the bronze which once covered the whole dome. The lower storey of the circular part and the walls of the projecting portico were covered with slabs of Greek marble ; a great part of the latter still remains, enriched with Corinthian pilasters and bands of sculptured ornament. The two upper storeys of the drum were covered outside with hard stucco of pounded marble. Inside the whole was lined with a great variety of rich oriental marbles. This magnificent interior, divided into two orders by an entablature supported on columns and pilasters, has been much injured by 1 A drawing of this interesting bronze work, by G. A. Dosio, is preserved in the Uffizi at Florence (No. 1021).

alteration.' About 608 the Pantheon was given by Phocas to Boniface IV., who consecrated it as the church of S. Maria ad Martyres. In 1881-82 the destruction of a row of houses TA behind the Pantheon exposed remains of a grand hall with . ' richly sculptured entablature on Corinthian columns, part Alai ooa of the great thermae of Agrippa, which extend beyond the ' Via della Ciambella. A great part of the thermae appears from the brick stamps to belong to an extensive reconstruction in the reign of Hadrian 4 (see BATHS).
Close by the Pantheon is the church of S. Maria sopra Minerva, which stands (as its name records) on or near the site of a temple to Minerva Chalcidica (Plan, No. 12), probably founded by Pompey the Great, c. 60 B.C. (Plin. H.N. vii. 97), and restored by Domitian. Adjoining this were temples to Isis and Serapis, a cult which became very popular in Rome in the time of Hadrian; large quantities of sculpture, Egypto-Roman in style, have been found on this site at many different times. 6 Several of the barracks (excubitoria) of the various cohorts of the vieiles or firemen have been discovered in various parts of Rome. That of the first cohort (Plan, No. 29) is buried under the Palazzo Savorelli; that of the second (Plan, No. 30) was on the Esquiline, near the so-called temple of Minerva Medica; that of the third (Plan, No. 31) was near the baths of Diocletian. The most perfect is that of the seventh cohort (Plan, No. 34), near S. Crisogono in Trastevere, a handsome house of the 2nd century, decorated with mosaic floors, wall-paintings, etc. 6 The excavations made in exposing the ancient church of S. Clemente brought to light interesting remains of different periods; drawings are given by Mullooly, St Clement and his Basilica (1869), and De Rossi, Bull. Arch. Crist. (1863), 28.
Some remains exist of the Golden House of Nero, which, including its parks, lakes, etc., covered an incredibly large space of ground, extending from the Palatine, over the Velia and the site of the temple of Venus and Rome, to the Esquiline, filling the great valley between the Caelian and the Esquiline where the Colosseum stands, and reaching far over the Esquiline to the great reservoir now called the " Sette Sale." No other extravagances or cruelties of Nero appear to have offended the Roman people so much as the erection of this enormous palace, which must have blocked up many important roads and occupied the site of a whole populous quarter. It was partly to make restitution for this enormous theft of land that Vespasian and Titus destroyed the Golden House and built the Colosseum and Thermae of Titus on part of its site. Adjoining the baths of Titus were those built on a much larger scale by Trajan. Under the substructions of these extensive remains of the Golden House still exist; 7 and at one point, at a lower level still, pavements and foundations remain of one of the numerous houses destroyed by Nero to clear the site. The great bronze colossus of Nero, 120 ft. high (Suet. Nero, 31), which stood in one of the porticus of the Golden House, was moved by Vespasian, with head and attributes altered to those of Apollo (Helios), on to the Velia; and it was moved again by Hadrian, when the temple of Rome was built, on to the base which still exists near the Colosseum. Several coins show this colossus by the side of the Colosseum.
Under the Palazzo Doria, the church of S. Maria in Via Lata, and other_ neighbouring buildings extensive remains exist of a great porticus, with long rows of travertine piers; this building, is designated on fragments of the marble plan with the words SAEPT . . . LIA. This must be the Saepta Julia, begun by Julius Caesar, and completed by Agrippa in 27 B.C., as the voting place for the Comitia Centuriata, divided into compartments, one for each century. The building contained rostra, and was also used for gladiatorial shows. Under the later empire it became a bazaar and resort of slave-dealers.
That curiously planned building on the Esquiline, in the new Piazza. Vit. Emmanuele, where the so-called trophies of Marius once were placed (see Du P6rac, Vestigi, pi. 27), is one of the numerous castella or reservoirs from which the water of the various aqueducts was distributed in the quarters they were meant to supply, and may perhaps be identified with the Nymphaeum Alexandri built Saepta Julia.
3 The bronze door is not in its present form antique, having been recast by order of Pius IV.

The Circus Maximus (see CIRCUS) occupied the Vallis Murcia 2 between the Palatine and the Aventine. Its first rows of seats, Circuses which were of wood, are said to have been made under the Tarquins (Liv. i. 26, 35; Dionys. iii. 68). Permanent carceres were set up in 329 B.C. and restored in 174 B.C. (Liv. viii. 20, xli. 27). In the reign of Julius Caesar it was rebuilt with (for the first time) lower seats of stone (Plin. H.N. xxxvi. 102), the upper being still of wood (Suet. Caes. 39) ; Dionysius (iii. 68) describes it as it was after this rebuilding. 1 1 was further ornamented with marble by Augustus, Claudius and other emperors. The wooden part was burnt in the great fire of Nero, and again under Domitian; it was considerably enlarged by Trajan, and lastly it was restored by Constantino. In its later state it had a marble facade with three external tiers of arches with engaged columns, and (inside) sloping tiers of marble seats, supported on concrete raking vaults (Plin. Paneg. 51). A great part of these vaults existed in the 16th century, and is shown by Du Perac. It is said by Pliny (H.N. xxxvi. 102) if the text be not corrupt to have held 250,000 spectators, while the Regionaiy Catalogues give the number of seats as 485,000; but Huelsen has shown (Bull. Comm. Arch., 1894, 421 ff.) that the figures are much exaggerated and must, moreover, be interpreted, not of the number of spectators, but of the length of the tiers expressed in feet. The end with the carceres was near the church of S. Maria in Cosmedin. 3 Some of its substructures, with remains of very early tufa structures on the Palatine side, still exist below the church of S. Anastasia (see Plan of Palatine). The obelisk now in the Piazza del Popolo was set on the spina by Augustus, and that now in the Lateran piazza by Constantius II. The Circus Flaminius in the Campus Martius was built in 221 B.C. by the C. Flaminius Nepos who was killed at the Trasimene Lake in 217 B.C.; remains of the structure existed until the 16th century, when they were destroyed to build the Palazzo Mattei. In the middle ages its long open space was used as a rope-walk, hence the name of the church called S. Caterina dei Funari, which occupies part of its site. 4 The circus of Caligula and Nero was at the foot of the Vatican Hill (Plin. H.N. xxxvi. 74). The modern sacristy of St Peter's stands over part of its site. The obelisk on its spina remained standing in situ till it was moved by Fontana 6 for Sixtus V. to its present site in the centre of the piazza. The great stadium, foundations of which exist under most of the houses of the Piazza Navona (Agonalis), and especially below S. Agnese, is that built by Domitian and restored by Severus Alexander. That it was a stadium and not a circus is shown by the fact that its starting end is at right angles to the sides and not set diagonally, as was always the case with the carceres of a circus; nor is there any trace of foundations of a spina. The best preserved circus is that built by Maxentius in honour of his deified son Romulus, by the Via Appia, 2 m. outside the walls of Rome. It was attributed to Caracalla till 1825, when an inscription recording its true dedication was found. 6 The first permanent naumachia was that constructed by Augustus between the foot of the Janiculan hill and the Tiber. The naumachia of Domitian was pulled down and the materials used to restore the Circus Maximus (Suet. Dom. 5) ; it was perhaps restored by Trajan, for the remains of a naumachia built of opus reticulatum mixed with brick have been discovered near the mausoleum of Hadrian.
The first stone theatre in Rome was that built by Pompey in 55-52 B.C. (see THEATRE: Roman) ; it contained a temple to Venus Theatres Victrix, and in front of it was a great porticus, called Hecatostylum from its hundred columns. This is shown on the marble plan. 7 Considerable remains of the foundations exist between the Piazza dei Satiri, which occupies the site of the 1 See Bruzza, in Ann. Inst. (1870), and Lenormant, Trophies de Marius, Blois (1842). This once magnificent building, with the marble trophies in their place, is shown with much minuteness on a bronze medallion of Severus Alexander (see Froehner, Medaillons de I'empire, Paris, 1878, p. 169).

3 Part of it is shown on a fragment of the marble plan (see Jordan, F.U.R.); it is represented on a bronze medallion of Gordian III., with an obelisk on the spina and three metae at each end ; in front are groups of wrestlers and boxers (see Grueber, Rom- Med. pi. xli., London, 1874).

scena, and the Via.de" Giubbonari and Via del Paradiso. Adjoining this was the porticus Pompeiana, which contained the curia of Pompey, where Caesar was murdered, after which it was walled up. The colossal statue, popularly supposed to be that of Pompey, at the feet of which Caesar died, 8 now in the Palazzo Spada, was found in '553 n ar the theatre. This theatre was restored by Augustus (Man. Anc. 4, 9) ; in the reign of Tiberius it was burnt, and its rebuilding was completed by Caligula. The scena was again burnt in A.D. 80, and restored by Titus. According to Pliny (H.N. xxxvi. 115), it held 40,000 spectators; the Regionary Catalogues give the number 17,580. Huelsen estimates its capacity at 9000- 10,000 spectators. In 1864 the colossal gilt bronze statue of Hercules, now in the Vatican, was found near the site of the theatre of Pompey, carefully concealed underground. The theatre of Marcellus is much more perfect; complete foundations of the cunei exist under the Palazzo Savelli, and part of the external arcade is well preserved. This is built of travertine in two orders, Tuscan and Ionic, with delicate details, very superior to those of the Colosseum, the arcade of which is very similar to this in general design. This theatre was begun by J. Caesar, and finished by Augustus in 13 B.C., who dedicated it in the name of his nephew Marcellus.' It was restored by Vespasian (Suet. Vesp. 19). Foundations also of the theatre dedicated by Cornelius Balbus in 13 B.C. (Suet. Aug. 29; Dio Cass. liv. 25) exist under the Monte dei Cenci; and in the Via dei Calderari there is a small portion of the external arcade of a porticus (Plan, No. 42) ; the lower storey has travertine arches with engaged columns, and the upper has brick-faced pilasters. This has been supposed to be the Crypta Balbi mentioned m the Regionary Catalogues, but is more probably the Porticus Minucia, built in 110 B.C. An interesting account of the temporary theatre of M. Aemilius Scaurus, erected in 58 B.C., is given by Pliny (H.N. xxxvi. 5, 113). The same writer mentions an almost incredible building, which consisted of two wooden theatres made to revolve on pivots, so that the two together made an amphitheatre; this was erected by C. Curio in 50 B.C. (H.N. xxxvi. 116).
The first stone amphitheatre in Rome was that built by Statilius Taurus in the reign of Augustus. (For the Colosseum and Amphlthe Amphitheatrum Castrense, see AMPHITHEATRE; for theatres. the Baths, see that article.)
Arches, Columns, Tombs and Bridges.
The earliest triumphal arches were the two erected by L. Stertinius (196 B.C.) in the Forum Boarium and in the Circus Maximus, out of spoils gained in Spain. 10 In the later years of the Arcbe* empire there were nearly forty in Rome. The arch of Titus and Vespasian on the Summa Sacra Via was erected by Domitian to commemorate the conquest of Judaea by Titus in his father's reign. Reliefs inside the arch represent the triumphal procession Titus in a chariot, and on the other side soldiers bearing the golden candlestick, trumpets and table of prothesis, taken from the Jewish temple. The central part only of this monument is original; the sides were restored in 1823." Another arch in honour pi Titus had previously been built (A.D. 80) in the Circus Maximus ; its inscription is given in the Einsiedeln MS. (C.I.L. vi. 944). A plain travertine arch near the supposed palace of Commodus on the Caelian is inscribed with the names of the Consul Publius Cornelius Dolabella (A.D. 10) and of the flamen martialis, C. Junius Silanus. It may have originally been used to carry the Aqua Marcia; in later times the Aqua Claudia passed over it. The socalled arch of Drusus by the Porta Appia also carries the specus of an aqueduct that built by Caracalla to supply his great thermae. Its composite capitals show, however, that it is later than the time of Drusus, and it was very possibly the work of Trajan. Adjoining the church of S. Giorgio in Velabro a rich though coarsely decorated marble gateway with flat lintel still exists built, as its inscription records, in honour of Severus and his sons by the argentarii (bankers and silversmiths) and other merchants of the Forum Boarium in 204. It formed an entrance from the Forum Boarium into the Velabrum. The figure of Geta in the reliefs and his name have been erased by Caracalla; the sculpture is poor both in design and execution (see Bull. Inst., 1867, p. 217, and 1871, p. 233). Close by is a quadruple arch, set at the intersection of two roads, such as was called by the 8 See Fea, Rom. Ant. Ixviii. 57, for an account of its discovery.

[me]i . esset." The temple of Apollo here named was one of the most ancient and highly venerated in Rome; it was dedicated to the Delphic Apollo in 431 B.C. by Cn. Julius (Liv. iv. 25); meetings of the Senate were held in it; and it contained many fine works of art an ancient cedar- wood statue of Apollo (Plin. H.N. xiii. n) and the celebrated statues of the slaughter of the Niobids by Praxiteles or Scopas (Plin. H.N. xxxvi. 28), of which many ancient copies exist.

11 This arch is the earliest known example of the so-called Composite order, a modification of Corinthian in which the capitals combine Ionic volutes with Corinthian acanthus leaves; in other respects it follows the Corinthian order.
(TOMBS AND BRIDGES Romans an arch of Janus Quadrifrons. Though partly built of earlier fragments, it is late in style, and may be the Arcus Constantini mentioned in the Xlth region. The finest existing arch is that by the Colosseum erected by Constantine. It owes, however, little of its beauty to that artistically degraded period. Not only most of its reliefs but its whole design and many of its architectural features were stolen from an earlier arch erected by Trajan as an entrance to his forum (see above). The arch of Claudius, built in 43 to commemorate his supposed victories in Britain, stood across the Via Lata (modern Corso) in the Piazza Sciarra. Its exact position is shown in Bull. Comm. Arch. Rom., 1878, pi. iv. Its remains were removed in the middle of the 16th century, 1 and nothing now is left but half its inscription, preserved in the garden of the Barberini palace. It is shown on both aurei and denarii of Claudius, with an attic inscribed DE BRITANNIS, and surmounted by a quadriga and trophies. A little to the N. of the Piazza Colonna was an arch popularly called the Arco di Portogallo, destroyed in 1665, whose reliefs are now in the Palazzo dei Conservatori. They appear to date from the reign of Hadrian, but may have been used at a later time to decorate this arch. An arch also stood opposite S. Maria in Via Lata until 1498, which was probably erected by Diocletian in A.D. 303. The central part of the once triple arch of Gallienus still exists on the Esquiline; it took the place of the ancient Porta Esquilina of the Servian wall. It is built of travertine, is simple in design, with coarse details, and has an inscription on its attic. The two side arches and pediment over the centre existed in the 16th century, and are shown in the Mantuan oil-painting of Rome, 2 and in several antiquarian works of the 16th century. The inscription (C.I.L. yi. 1106) records that it was erected in honour of Gallienus and his wife Salonina by Aurelius Victor. 8 The column of Antoninus Pius was a monolith of red granite, erected after his death by his adopted sons M. Aurelius and L. Verus. One fragment of it is preserved in the Vatican Columns. w ; t jj an j n t cres tj n g quarry incription, recording that it was cut in the ninth year of Trajan's reign, under the supervision of Dioscurus and the architect Aristides. The rest of its fragments were used by Pius VI. to repair the obelisk of Monte Citorio, set up by Augustus in the Campus Martius as the gnomon of a sundial (Plin. H.N. xxxvi. 72). The marble pedestal of the Antonine column is now in the Vatican; it has reliefs representing the apotheosis of Faustina and Antoninus Pius, and the decursio equitum which formed part of the funeral ceremony. This and the column of M. Aurelius were both surmounted by colossal portrait statues of gilt bronze. The column of M. Aurelius is very similar in size and design to that of Trajan. Its spiral reliefs represent victories in Germany from 171-175, arranged in twenty tiers. Like the column of Trajan, it is exactly 100 Roman ft. high, without the pedestal. The pedestal was originally much higher than at present, but is now partly buried; it is shown by Gamucci, Du Perac and other 16th-century writers. This column stood in front of a temple to M. Aurelius, and within a great peribolus, forming a forum similar to that of Trajan, though much smaller; the remains of this temple, amongst other buildings, probably form the elevation nw called Monte Citorio. 4 For the catacombs, see CATACOMBS; for obelisks, see OBELISK and Egypt.
The prehistoric cemeteries of Rome are described above (Prehistoric Rome). Few tombs exist of the Roman period earlier than the 1st _ . century B.C., probably owing to the great extension of the city beyond the Servian limits, which thus obliterated the earlier burial-places. The tomb of the Cornelii Scipiones is the most important of early date which still exists. It is excavated in the tufa rock at the side of the Via Appia, outside the Porta Capena. Interments of the Scipio family went on here for about 400 years, additional chambers and passages being excavated from time to time. The peperino sarcophagus of Lucius Cornelius Scipio Barbatus (Liv. x. 12, 13), consul in 298 B.C., is now in the Vatican; its inscription, in rude Saturnian verse, is one of the most important existing specimens of early Latin epigraphy. Many other inscribed slabs were found in the 17th century, covering the loculi in which lay the bodies of later members of the family. Those now existing in the tomb are modern copies. 5 This burial-place of the Scipios is unlike those of other families, owing to the gens Cornelia keeping up the early custom of interment without burning; thus stone sarcophagi or loculi (rock-cut recesses) were required instead of mere pigeonholes to hold the cinerary urns.

discovered during the destruction of the Aurelian towers at the Porta Salara, date from about the middle of the 1st century B.C., as does also the curious tomb of the baker Eurysaces outside the Porta Maggiore. In 1863 an interesting tomb of the Sempronia gens' was discovered on the Quirinal, below the royal palace, near the site of the Porta Salutaris. It is of travertine, with a rich entablature and frieze sculptured with the Greek honeysuckle ornament (see Bull. Comm. Arch., 1876, 126, pi. xii.). This also isof the last years of the republic.
The mausoleum of Augustus, built 28 B.C., stood in the north part of the Campus Martius, between the Tiber and the Via Flaminia. It is a massive cylindrical structure of concrete, faced with opus reticulatum ; according to Strabo, this was faced with " tttusolea - " white stone," i.e. travertine; inside was a series of radiating chambers, in plan like a wheel. On the top was a great mound of earth, planted with trees and flowers (Tac. Ann. lii. 9). In the middle ages it was converted into a fortess by the Colonna, which was destroyed in 1167. In the 16th century the central portion was occupied by a garden. 7 Only the bare core exists now, with its fine opus reticulalum, best seen in the court of the Palazzo Valdambrini. The inside is concealed by modern seats, being now used as a concert-hall (Anfiteatro Chorea). The sepulchral inscription in honour of Augustus, engraved on two bronze columns at the entrance, is preserved to us by its copy at Ancyra (q.v.). It records an almost incredible amount of building: in addition to the long list of building mentioned by name Augustus says, DVO. ET. OCTAGINTA. TEMPLA . DEVM . IN .VRBE . CONSVL . SEXTVM . REFECI. The first burial in the mausoleum of Augustus was that of M.Claudius Marcellus (died 23 B.C.), and it continued to be the imperial tomb till the death of Nerva, A.D. 98, after whose interment there was no more room.
The mausoleum of Hadrian, built by that emperor as a substitute for that built by Augustus, and dedicated in A.D. 138 by his successor, was a large circular building on a square podium; its walls, of enormous thickness, were of tufa fared with Parian marble and surrounded by a colonnade with rows of statues, a work of the greatest magnificence. The splendour of the whole is described by Procopius (Bell. Goth. i. 22), who mentions its siege by the Goths, when the defenders hurled statues on to the heads of the enemy. In the 7th century the church of S. Angelus inter Nubes was built on its summit, and all through the middle ages it served as a papal fortress. The interior chambers are still well preserved, but its outside has been so often wrecked and refaced that little of the original masonry is visible. 8 Several of the grander sepulchral monuments of Rome were built in the form of pyramids. One of these still exists, included in the Aurelian wall, by the Porta Ostiensis. It is a pyramid of concrete, 118 feet high, faced with blocks of white marble, Se P ul ~ and contains a small chamber decorated with painted c '"" a ' stucco. An inscription in large letters on the marble Py ramlds - facing records that it was built as a tomb for C. Cestius, a praetor, tribune of the people, and septemvir of the epulones (officials who supervised banquets in honour of the gods). It was erected, according to Cestius's will, by his executors, in the space of 330 days. It dates from the time of Augustus 9 (see Falconieri, in Nardini, Roma Antica, iv. p. i, ed. 1818-20). Another similar pyramid, popularly known as the tomb of Romulus, stood between the mausoleum of Hadrian and the basilica of St Peter. It was destroyed at the close of the 15th century, during the rebuilding of the long bridge which connects the former building with the Vatican.
The earliest bridge was a wooden drawbridge called the Pens Sublicius from the piles (sublicae) on which it was built. The river being an important part of the defence of Rome from the Aventine to the Porta Flumentana (see plan of Servian wall, fig. 8), no permanent bridges were made till the Romans were strong enough not to fear attacks from without. The Pons Sublicius had a sacred character, and was always restored in wood, even in the imperial period. 10 Its exact site is doubtful, but it must be placed some distance below the Ponte Rotto. The first stone bridge was begun in 179 B.C. and completed in 142 B.C., when the conquest of Etruria and the defeat of Hannibal had put an end to fears of invasion ; it was called the Pons Aemilius, after the pontifex maximus 11 M. Aemilius Lepidus, its founder. It was also called Pons This is shown by an inscription (C.I.L. vi. 26152) found on the site in the 17th century.

8 On the mausoleum of Hadrian, see Borgatti, Castel S. Angela (1890).
9 Near the tomb of Cestius is that extraordinary mound of potsherds called Monte Testaccio. These are mostly fragments of large amphorae, not piled"* up at random, but carefully stacked, with apertures at intervals for ventilation. It has been shown by Dressel (Ann. dell' Inst., 1878, 118 ff.; C.I.L. xv. p. 492) that damaged or imperfect vessels were thus disposed of.
"See Varro, L.L. v. 83; Ov. Fast. v. 622; Tac. Hist. i. 86; Vila Antonini Pii, 8.

Lapideus, to distinguish it from the wooden Sublician bridge. The modern Ponte Rptto represents this bridge ; but the existing arches are mainly medieval. An ancient basalt-paved road still exists, leading to the bridge from the Forum Boarium. The Pons Fabricius united the city and the island (Insula Tiberina). 1 The bridge derived its name from L. Fabricius, a curator viarum in 62 B.C ; its inscription, twice repeated, is L, . FABRICIVS . C . F . CVR . VIAR . FACIVNDVM . COERAVIT. Like the other existing bridges, it is built of great blocks of peperino and tufa, with a massive facing of travertine on both sides. Corbels to support centering were built in near the springing of the arches, so that they could be repaired or even rebuilt without a scaffolding erected in the river-bed. The well-preserved Pons Cestius, probably named after L. Cestius, praefectus urbi in 46 B.C., unites the island and the Janiculan side; on the marble parapet is a long inscription recording its restoration in 370 by Gratian, Valentinian, and Valens. 2 The next bridge, Ponte Sisto, is probably on the site of an ancient bridge called in the Notitia Pons Aurelius. Marliano gives an inscription (now lost) which recorded its restoration in the time of Hadrian. About lop yards above this bridge have been found the remains of sunken piers, which are proved by an inscription (C.I.L. vi. 31545) to have belonged to the Pons Agrippac, not otherwise known. The Pons Aelius was built in 134 by Hadrian, to connect his mausoleum with the Campus Martius; it is still well preserved, and is now called the Ponte S. Angelo (see Dante, Inferno, xviii. 28-33). It had eight arches, of which the three in the centre were higher than the rest, so that the road sloped on both sides. The material is peperino, with travertine facings. Its inscription, now lost, is given in the Einsiedeln MS. IMP . CAESAR . Divi . TR AIANI .
PARTHICI . FILIVS .DIVI- NERVAE. NEPOS . TRAIANVS . HADRI- ANVS AVG . PONT . MAX . TRIB . POT . XVIIII . COS . Ill . P . P . FECIT. The Pons Aelius is shown on coins of Hadrian. A little below it are the foundations of another bridge, probably the Pons Neronianus of the H^irabilia, called also Vaticanus, built probably by Nero as a way to his Vatican circus and the Horti Agrippinae. At the foot of the Aventine, near the Marmorata, are the remains of piers which seem to have belonged to the Pons Probi, mentioned in the Notitia. It is uncertain whether this bridge is to be identified with the Pons Theodosii, which was built in A.D. 381-387 (Symm. Ep. 4, 70, 2; 5, 76, 3), and is mentioned in the Mirabilia. 1 Regiones of Augustus.
In spite of the extensive growth of the city under the republic no addition was made to the four regiones of Servius till the reign of Augustus, who divided the city and itssuburbs into fourteen regiones. The lists in the Notitia and Curiosum are the chief aids in determining the limits of each, which in many cases cannot be done with any exactness (see Preller, Die Regionen der Stadt Rom (1846) and Urlich's Codex Topographicus (Wtirzburg, 1871)). Each regio was divided into vici or parishes, each of which formed a religious body, with its aedicula larum, and had magistri victorum. The smallest regio (No. II.) contained seven vici, the largest (No. XIV.) seventy-eight.
The list is as follows :
I. Porto, Capena, a narrow strip traversed by the Appian Way ; it extended beyond the walls of Aurelian to the brook Almo. II. Gaelemontium, the Caelian Hill.
III. Isis et Serapis, included the valley of the Colosseum and the adjoining part of the Esquiline.
IV. Templum Pads, included the Velia, part of the Cispius, most of the Subura, the fora of Nerva and Vespasian, the Sacra Via, and also buildings along the north-east side of the Forum Magnum.
V. Esquiliae, north part of the Esquiline and the Viminal. VI. Alto, Semita, the Quirinal as far as the praetorian camp. VII. Via Lata, the valley bounded on the west by the Via Lata, and by the neighbouring hills on the east. VIII. Forum Romanum, also included the imperial fora and the Capitoline hill. IX. Circus Flaminius, between the Tiber, the Capitol, and the Via Flaminia.
X. Palatium, the Palatine hill. XI. Circus Maximus, the valley between the Palatine and the Aventine, with the Velabrum and Forum Boarium. XII. Piscina Publica, the eastern part of. the Aventine, and the districts south of and beyond the Via Appia, including the site of Caracalla's thermae.
1 Livy (ii. 5) gives the fable of the formation of this island from the Tarquins' corn, cut from the Campus Martius and thrown into the river.

Trans Tibenm, the whole district across the river and the Tiber Island. 4 The walls of Aurelian (see fig. 7), more than 12 m. in circuit, enclosed almost the whole of the regiones of Augustus, the greater part of which were then thickly inhabited. This enormous work was begun in 271, to defend Rome against sudden *"""" attacks of the Germans and other northern races when the " great armies of Rome were fighting in distant countries.' After the death of Aurelian the walls were completed by Probus in 280, and about a century later they were restored and strengthened by the addition of gate-towers under Arcadius and Honorius (A.D. 403). in place of the earlier gateways of Aurelian; this is recorded by existing inscriptions on three of the gates. 8 At many periods these walls suffered much more from the attacks of the Goths (Procop. Bell. Goth. iii. 22, 24), and were restored successively by Theodonc (about 500), by Belisarius (about 560), and by various popes during the 8th and gth centuries, and in fact all through the middle ages. A great part of the Aurelian wall still exists in a more or less perfect state; but it has wholly vanished where it skirted the river, and a great part of its trans-Tiberine course is gone. The best-preserved pieces are between Porta Pinciana and Porta Salaria (in which breaches have lately been made for streets), and between the Lateran and the Amphitheatrum Castrense. The wall, of concrete, has the usual brick-lacing and is about 12 ft. thick, with a guard's passage formed in its thickness. Fig. 13 shows its plan: on the inside the FIG. 13. Aurelian's Wall; plan showing one of the towers and the passage in thickness of wall.
passage has tall open arches, which look like those of an aqueduct, and at regular intervals of about 45 ft. massive square towers are built, projecting on the outside of the wall, in three storeys, the top storey rising above the top of the wall. The height of the wall varies according to the contour of the ground; in parts it was about 60 ft. high outside and 40 inside. Necessaria, supported on two travertine corbels, projected from the top of the wall on the outside beside most of the towers. The Einsiedeln MS. gives a description of the complete circuit, counting fourteen gates, as follows:
Porta S. Petri (at the Pons Aelius, destroyed); P. Flaminia (replaced by P. del Popolo) ; P. Pinciana (in use) ; P. Salaria (now P. Salara); P. Nomentana (replaced by P. Pia); P. Tiburtina (now P. S. Lorenzo) ; P. Praenestina (now P. Maggiore) ; P. Asinaria (replaced by P. San Giovanni); P. Metrovia or Metroni (closed); P. Latina (closed) ; P. Appia (now P. S. Sebastiano) ; P. Ostiensis (now P. S. Paolo). On the Janiculan side, P. Portuensis ( destroyed); P. Aurelia (now Porta San Pancrazio). Besides these there was a gate, now closed (Porta Chiusa), to the south of the Castra Praetoria ; and in all probability a gate on the right bank of the Tiber, replaced by the modern Porta Settimiana.
These existing gates are mostly of the time of Honorius; each is flanked by a projecting tower, and some are double, with a second pair of towers inside. Several have grooves for a portcullis ( cataracta) in the outer arch. The handsomest gate is the P. Appia, with two massive outer towers, three stages high, the upper semicircular in plan. Many of the gates of Honorius have Christian symbols or inscriptions. The general design of all these gates is much the same a central archway, with a row of windows over it and two flanking towers, some square, others semicircular in plan. In many of the gates older materials are used, blocks of tufa, travertine, or marble. The doors themselves swung on pivots, the bottom ones let into a hole in the threshold, the upper into projecting corbels.
At many points along the line of the Aurelian wall older buildings form part of the circuit near the Porta Asinaria a large piece of 4 The text of the Regionary Catalogues is printed by Richter, Topographic der Stadt Rom? pp. 371 ff.

the Domus Lateranorum, a house of the 3rd century which gave its name to the Lateran basilica, and a little farther on, by S. Croce in Gerusalemme, the Amphitheatrum Castrense; the latter, of about the end of the 1st century A.D. , has two tiers of arches and engaged columns of moulded brick on the outside. Between the P. Praenestina and the P. Tiburtina comes a large castellum of the Aqua Tepula. The Praetorian Camp forms a great projection near the P. Nomentana. -Lastly, the angle near the Porta Flaminia, at the foot of the Pincian Hill, is formed by remains of a lofty and enormously massive building, faced with fine opus reticulatum of the 1st century B.C. Owing to the sinking of the foundation this is very much out of the perpendicular, and was known as the " murus tortus " at a very early time. 1 What this once important building was is uncertain. Two archways which form gates in the Aurelian wall are of much earlier date. The Porta Maggiore consists of a grand double arch of the aqueducts Anio Novus and Claudia built in travertine. The Porta S. Lorenzo enclosed a single travertine arch, built by Augustus where the aqueduct carrying the Aqua Marcia, Tepula, and Julia crossed the Via Tiburtina. The inner gateway, built of massive travertine blocks by Honorius, was pulled down by Pius IX., in 1868. 2 Bibliography of Ancient Roman Topography. Amongst ancient writers special mention is due to Varro (De Lingua Z,o/iKa),Dionysius of Halicarnassus (Antiquitates Romanae), Ovid (Fasti), Vitruvius (De Architectura) , Pliny the Elder (Naturalis Historia), Frontinus (De Aquis) and the remains of ancient commentaries on Virgil, Horace, etc. The inscriptions found in the city of Rome are contained in vol. VI. of the Corpus Inscriptionum Latinarum. Many of them are of the highest importance for Roman topography, e.g. the Basis Capitolina, preserved in the Palazzo dei Conservator!, a pedestal which once supported a statue of Hadrian, dedicated in A.D. 136 by the vicomagistri of five regions; on the sides are inscribed the names of the vici and their officials. Vol. XV. of the C.I.L. contains the inscriptions stamped on tiles and water-pipes, which are likewise of great importance. The Monumentum Ancyranum (Res gestae dim Augusti, ed. 2 Mommsen, 1883) reproduces the bronze tablets set up by Augustus on his mausoleum at Rome, and contains a list of the buildings which he erected or restored. The marble plan of Rome (Forma urbis Romae, ed. Jordan, 1874; the more recently discovered fragments have only been published in periodicals) dates from the reign oiSeptimius Severus, who restored the building to which it belonged after the fire of 191 B.C. The plan which it replaced was executed by order of Vespasian. The scale was generally l: 250; it was oriented with S.E. at the top, N.W^ at the bottom. Buildings are of course frequently represented on coins and works of art, and these may often be identified with existing remains.
In the reign of Constantine the Great there was compiled a catalogue of the principal buildings of Rome, arranged according to the fourteen regions of Augustus. This has been preserved in two recensions, one made in A.D. 334 and known as the Notitia, the second in or about A.D. 357, and known as the Curiosum urbis Romae. These are called the Regionary Catalogues, and contain, besides lists of buildings, statistics as to the number of vici, domus, insulae, etc., in each region, which are of great value. (See Preller, Regionen der Stadt Rom, Jena, 1846.)
In the middle ages, guide-books were written for the use of pilgrims visiting Rome. Besides giving the routes for the principal churches and cemeteries, they mention ancient buildings and give current legends regarding them. The earliest is the Itinerary of Einsiedeln, a MS. of the 8th century preserved in the monastery of Einsiedeln in Switzerland (see C. Huelsen, L'ltinerario di Einsiedeln, 1908). In the 12th century was compiled the Mirabilia urbis Romae, which became the foundation of later guide-books. The last recension is contained in a MS. of the early 15th century. These and other medieval documents are printed in Urlichs' Codex Topographicus urbis Romae (1871). The Ordo Benedicti Canonici (see Jordan, Topographie, II. I, 646, and Lanciani, Monumenti Antichi, I. 437), which gives the route of papal processions, belongs also to the 12th century, and was perhaps written by the author of the Mirabilia. The Liber Pontificalis (ed. Duchesne, Paris, 1886; ed. Mommsen, in Monumenta Germaniae historica, vol. i.), which gives the biographies of the early popes and was continued throughout the middle ages, is of value as illustrating the transition from pagan to Christian Rome.
Several early views and plans of Rome exist, beginning with the painting by Cimabue in the upper church of S. Francesco at Assisi (1275). A collection of these was published by De Rossi, Piante icnografiche e prospettiche di Roma anteriori al secolo XVI. (1879). Many others have since come to light. (See Huelsen in Bull. Comm. Arch., 1892, p. 38).
In Italian and other libraries are preserved large numbers of 1 Cf. Procop. Bell. Goth. i. 23.

plans and drawings from ancient remains by the architects of the 15th and later centuries, e.g. Bramantino, Fra Giocondp, the members of the families of Sangallo and Peruzzi, Pirro, Ligorio, Palladio, etc. These are of immense value, since the monuments which they drew have to a large extent been destroyed. Unfortunately they are not always trustworthy, especially those of Ligorio. The drawings at Florence have been indexed by Ferri; amongst recent publications may be noted those of the Codex Escortalensis by Egger (Vienna, 1905), and of a sketch-book, probably by A. Coner, in the Soane Museum by Dr Ashby, in Papers of the British School at Rome, vol. ii. (1903). Amongst the printed works of the early Italian architects may be named Palladio, Architettura (Venice, 1542), and Terme dei Romani (London, 1732), Serlio, Architettura (Venice, 1545), and Labacco, 'Architettura ed Antichita, (Rome 1557). Engravings of ancient remains in Rome have been published in great numbers since the 16th century; the most important of the earlier collections are the Speculum Romanae Magnificentiae,a. series extending over many years in the 16th century, and Du Perac's Vestigj di Roma (1575). To the 18th century belong the etchings of Piranesi, published in several volumes, and still reproduced from the copper-plates by the Calcografia.
The literature of Roman topography would in itself form a large library; the best bibliographical guide is Mau's Katalog der Bibliothek des k. deutschen archdologischen Instiluts in Rom (1900). The earliest modern work which can be called scientific is Flavio Biondo's Roma instaurata, written under Eugenius IV. (1431-1447), first dated edition, 1479. Biondo's work was based on the study of ancient literary authorities; he was followed in his method and results by the scholars of the 15th and early 16th centuries, e.g. Pozzo, Leo Battista Alberti and Andrea Fulvio. In the 16th century the study of ancient remains took its place beside that of ancient literature. Marliani, who had followed Biondo in the first edition of his Antiquae urbis Romae topographia (1538), issued a second edition in 1544, which contained plans and illustrations. For more than a century his book formed the foundation upon which such writers as Fauno, G. Fabricius, Mauro, Panvinius, etc., raised their works. Unfortunately the Regionary Catalogues were largely interpolated during this period, and published in this form by Panvinius. In 1666 Famiano Nardini's Roma antica appeared, based upon the interpolated version of the Regionary Catalogues; this was productive of disastrous errors, many of which remained uncorrected until our own time. Nardini was followed in the 18th century by such writers as Ficoroni and Vertuti; the most important works of this period were those produced by excavators such as Bianchini (// palazzo dei Cesari, 1738), or independent students of the monuments such as Raphael Fabretti (De Columna Trajana, 1683; De Aquis et Aquaeductibus,_ 1680). In the 18th century Winckelmann revived interest in ancient, including Roman, art (especially by his Geschichte der Kunst des Alterthums, 1764), and his follower, Carlo Fea, inaugurated the era of systematic and scientific excavation, especially in the Forum. In 1829 there was founded the international Institute di Corrispondenza Archeolpgica (which in 1874 became the Kaiserlich deutsches archdologisches Institut); in 1830-42 was issued the Beschreibung der Stadt Rom, by Bunsen and others, in which the grosser errors which had passed current since Nardini's time were corrected. To the same period belong the magnificently illustrated works of Luigi Canina ( Indicaziorx di Roma antica, 1830; Esposizione topografica, 1842; Architettura antica, 1834-44; F ro Romano, 1845; Edifizj di Roma antica, 1848-56), the value of which is impaired by their inaccuracy and the imaginative character of the restorations.
The books on Roman topography written in the early 19th century, such as those of Antonio Nibby, still pursued the uncritical methods of Nardini; from 1830 onwards, however, we find a series of writers whose work shows the influence of the new criticism. Such were Becker (Topographie der Stadt Rom, 1843), Sir Wm. Cell (Rome and its Vicinity, 1834; rev. ed. E. H. Bunbury, 1846), Braun (Ruinen und Museen Roms, 1854), Reber (Die Ruinen Roms, 1862) and T. H. Dyer (The City of Rome, 1864).
Since 1861, when excavations were begun on the Palatine at the instance of Napoleon III., under the direction of P. Rosa, the discovery of ancient remains has made constant progress, and the results have been incorporated in a number of works, of which only the most important can be named here. These are: Jordan, Topographie der Stadt Rom im Alterthum, of which three yols. (Ii, 12, and II.) appeared in 1871-85, and a third (13) was written after Jordan's death by C. Huelsen and published in 1907; Gilbert, Geschichte und Topographie der Stadt Rom im Alterthum (3 vols., 1883-90); the works of Lanciani, especially Ruins and Excavations of Ancient Rome (1897) and Storia degli Scavi (in progress); O. Richter, Topographie der Stadt Rom (ed. 2, 1901); Middleton, The Remains of Ancient Rome (2 vols., 1892). A short handbook may be found in S. B. Platner's Topography and Monuments of Ancient Rome (Boston, 1904). For the study of recent discoveries (besides the special works referred to in the course of this article) the following periodicals are the most important: Notizie degli Scavi, published by the Accademia dei Lincei since 1876; Buttettino delta Commissions Archeologica comunale di Roma (from 1872) ; Mittheilungen des k. deutschen archdologischen Instituts (from 1886) ; Papers of the British School at Rome (from 1903). Brief reports of discoveries are published by Dr T. Ashby in the Classical Review.
AH previous archaeological maps of Rome have been superseded by Lanciani's Formae urbis Romae, in 46 sheets (Milan, 18931902). The best recent maps are those in Kiepert's Formae orbis antiqui, sheets 21 and 22. Kiepert and Huelsen's Formae urbis Romae antiquae date from 1896; they are accompanied by a Nomenclator topographicus. Homo, Lexique de topographie romaine (1900), is also useful. (J. H. M.; H. S. J.)
