'OMAR KHAYYAM [in full, Ghiyathuddin Abulfath 'Omar bin Ibr.ahim al-Khayyami], the great Persian mathematician, astronomer, freethinker and epigrammatist, who derived the epithet Khayyam (the tentmaker) most likely from his father's trade, was born in or near Nishaptir, where he is said to have died in a.h. 517 (a.d. 1123). At an early age he entered into a close friendship both with Nizam-ul-mulk and his schoolfellow Hassan ibn Sabbah, who founded afterwards the terrible sect of the Assassins. When Nizam-ul-mulk was raised to the rank of vizier by the SeljUk sultan Alp-Arslan (a.d. 1063-1073) he bestowed upon Hassan ibn Sabbah the dignity of a chamberlain, whilst offering a similar court office to 'Omar Khayyam. But the latter contented himself with an annual stipend which would enable him to devote aU his time to his favourite studies of mathematics and astronomy. His standard work on algebra, written in Arabic, and other treatises of a similar character raised him at once to the foremost rank among the mathematicians of that age, and induced Sultan Malik-Shah to summon him in A.H. 467 (a.d. 1074) to institute astronomical observations on a larger scale, and to aid him in his great enterprise of a thorough reform of the calendar. The results of 'Omar's research were - a revised edition of the Zij or astronomical tables, and the introduction of the Ta'rikh-i-Malikshahl or Jalali, that is, the so-called JalaUan or Seljuk era, which commences in a.h. 471 (a.d. 1070, isth March).
"Omar's great scientific fame, however, is nearly eclipsed by his still greater poetical renown, which he owes to his rubd'is or quatrains, a collection of about 500 epigrams. The peculiar form of the ruba'i - viz. four lines, the first, second and fourth of which have the same rhyme, while the third usually (but not always) remains rhymeless - was first successfully introduced into Persian literature as the exclusive vehicle for subtle thoughts on the various topics of Sufic mysticism by the sheikh AbQ Sa'ld bin Abulkhair,' but 'Omar differs in its treatment considerably from Abu Sa'ld. Although some of his quatrains are purely mystic and pantheistic, most of them bear quite another stamp; they are the breviary of a radical freethinker, who protests in the most forcible manner both against the narrowness, bigotry and uncompromising austerity of the orthodox ulema and the eccentricity, hypocrisy and wild ravings of advanced Siifis, whom he successfully combats with their own weapons, using the whole mystic terminology simply to ridicule mysticism itself. There is in this respect a great resemblance between him and Hafiz, but 'Omar is decidedly superior. He has often been called the Voltaire of the East, and cried down as materialist and atheist. As far as purity of diction, fine wit, crushing satire against a debased and ignorant clergy, and a general sympathy with suffering humanity are concerned, "Omar certainly reminds us of the great Frenchman; but there the comparison ceases. Voltaire never wrote anything equal to 'Omar's fascinating rhapsodies in praise of wine, love and all earthly joys, and his passionate denunciations of a malevolent and inexorable ' Died Jan. 1049.

fate which dooms to slow decay or sudden death and to eternal oblivion all that is great, good and beautiful in this world. There is a touch of Byron, Swinburne and even of Schopenhauer in many of his rubd'is, which clearly proves that the modern pessimist is by no means a novel creature in the realm of philosophic thought and poetical imagination.
The Leiden copy of 'Omar Khayyam's work on algebra was noticed as far back as 1742 by Gerald Meerman in the preface to his Specimen calculi fluxionalis ; further notices of the same work by Scdillot appeared in the Nouv. Jour. As. (1834) and in vol. xiii. of the Notices et extrails des MSS. de la Bibl. roy. The complete text, together with a French translation (on the basis of the Leiden and Paris copies, the latter first discovered by M. Libri, see his Histoire des sciences mathemaliques en Italic, i. 300), was edited by F. Woepcke, L'Algebre d'Omar Alkhayydmi (Paris, 1851). Articles on 'Omar's life and works are found in Reinaud's Geographie d' Abonlfeda, pref., p. loi ; Notices et extrails, ix. 143 seq.; Garcin de Tassy, Note siir les Rubd'iyat de 'Omar Hhaiyam (Paris, 1857); Rieu, Cat. Pers. MSS. in the Br. Mus., ii. 546; A. Christensen, Recherches sur les Ruba'iyat de 'Omar IJayyani (Heidelberg, 1905); V.

Browne, Literary History of Persia, ii. 246. The quatrains have been edited at Calcutta (1836) and Teheran (1857 and 1862); text and French translation by J. B. Nicolas (Paris, 1867) (very incorrect and misleading); a portion of the same, rendered in English verse, by E. FitzGerald (London, 1859, 1872 and 1879). FitzGerald's translation has been edited with commentary by H. M. Batson (1900), and the 2nd ed. of the same (1868) by E. lieron Allen (1908). A new English version was published in Triibner's " Oriental " series (1882) by E. H. Whinficld, and the first critical edition of the text, with translation, by the same (1883). Important later works are N. H. Dole's variorum edition (1896), J. Payne's translation (1898), E. Heron Allen's edition (1898) and the Life by ]. K. M. Shirazi (1905); but the literature in new translations and imitations has recently multiplied exceedingly. (H. E. ; X.)
