ROCK, DANIEL (1790-1871), English Roman Catholic priest and ecclesiologist, was born at Liverpool on the 313! of August 1799, and educated at St Edmund's College, Ware, Herts, and at the English College, Rome. He was ordained priest in 1824 and successively appointed chaplain to the 16th earl of Shrewsbury at Alton Towers, Staffordshire, and priest in charge of the Roman Catholic congregation at Buckland, near Faringdon in Berkshire. After trie re-establishment of the Roman Catholic hierarchy in England, in which he had taken an active part, Rock was elected a canon of St George's Cathedral, Southwark. He was greatly interested in medieval art, and, having gone to live at South Kensington in 1864, in order to be near the museum, was of great assistance to the authorities there. He died on the 28th of November 1871.
Rocks principal works are: Hierurgia, or the Holy Sacrifice of the Mass expounded (London, 1833; revised edition by VV. 11. f Weale, 1893), an exhaustive account of the Eucharistic rites in the Latin, Greek and Oriental Churches, and illustrated from early paintings, sculptures and inscriptions; The Church of Our Fathers as seen in St Osmund's Rite for the Cathedral of Salisbury, with Dissertations on the Belief and Ritual in England before the Coming, of the Normans (3 vols., 1849-54; new edition by G. W. Hart anc W. H. Frere, London, 1903).
See the Memoir prefixed to Hart & Frere's edition of The Church of Our Fathers by the Rev. B. VV. Kelly; a full list of his writings is given in J. Gillow's Btbl. Diet, of the Engl. Catholics, vol. v. p. 436 ROCK (O.Fr. roke, Sp. roca, Ital. rocca; possibly from a Lat form rupica, from rupes, rock), in geology a mass of the mineral matter of which the crust of the earth is composed (see PETROLOGY and GEOLOGY). In more general usage a " rock " is a large mass of this mineral matter, as distinguished from smaller pieces which are termed " stones."
From this word must be distinguished the verb " to rock " to swing an object to and fro, particularly of a cradle in which a child is rocked to sleep, the original meaning. The O.Eng. word is rocctan, and is cognate with many words in Teutonic languages, e.g. Du. rukkea, Dan. rykke, Ger. rilcken, to pull, tug, push.
