It is highly probable that the first Roman Catacombs were excavated by the Jews.[31] Many Hebrew captives graced the triumph of Pompey after his Syrian conquests, B. C. 62. The Jewish population increased by further voluntary accessions. They soon swarmed in that Trans-Tiberine region which formed the ancient Ghetto of Rome. They made many proselytes from paganism to the worship of the true God, and thus, to use the language of Seneca, “The conquered gave laws to their conquerors.”[32] All the national customs and prejudices of the Jews were opposed to the Roman practice of burning the dead, which Tacitus asserts they never observed;[33] and they clung with tenacity to their hereditary mode of sepulture. Wherever they have dwelt they have left traces of subterranean burial. The hills of Judea are honeycombed with 50 sepulchral caves and galleries. Similar excavations have been found in the Jewish settlements of Asia Minor, the Ægean Isles, Sicily, and Southern Italy.[34] So also in Rome they sought to be separated in death, as in life, from the Gentiles among whom they dwelt. They had their Catacombs apart, in which not a single Christian or pagan inscription has been found. Bosio describes one such Catacomb, which he discovered on Monte Verde, which was much more ancient than the Christian Catacomb of St. Pontianus in the same vicinity. It was of very rude construction, and contained not a single Christian monument, but numerous slabs bearing the seven-branched Jewish candlestick, and one inscription on which the word ϹΥΝΑΓΩΓ--Synagogue--was legible.[35] It was situated near that Trans-Tiberine quarter of the city inhabited at the period of the Christian era by the numerous Jewish population of Rome. It cannot now, however, be identified, having been obliterated or concealed by the changes of the last two centuries. Maitland gives the following Jewish inscription from a MS. collection in Rome. The figure to the left may be a horn for replenishing the lamp with oil. The letters at the right are probably intended for the Hebrew word שָׁלוֹם _Shalom_, or Peace, so common in its classical equivalent upon Christian tombs. The palm branch is a Pagan as well as Jewish and Christian symbol of victory. The central figure is a rude representation of the seven-branched candlestick which appears also in 51 bass-relief on the Arch of Titus at Rome. [Illustration: “Here lies Faustina.
