For the fourth time the Jewish people seemed on the brink of extermination. Nebuchadrezzar, Antiochus, Titus, and Hadrian had successively exerted their utmost power to extinguish their existence as a separate people. Yet in less than sixty years after the war under Hadrian, before the close of the second century after Christ, the Jews present the extraordinary spectacle of two separate and regularly organised communities--one under the Patriarch of Tiberias, comprehending all of Isrælitish descent who inhabited the Roman Empire; the other under the Prince of the Captivity, to whom all the eastern Jews paid allegiance. By the mild temper of Antoninus Pius, the Jews were restored to their ancient privileges. Though still forbidden to enter Jerusalem, they were permitted to acquire the freedom of Rome, to establish many settlements in Italy, and to enjoy municipal honours. This gentle treatment assuaged the stern temper of the race. Awakened from their dream of prophecy and conquest, they assumed the behaviour of peaceable and industrious subjects. The worship of the synagogue became the great bond of racial union, and through centuries held the scattered nation in the closest uniformity. The middle of the third century beheld all Isræl incorporated into their two communities, under their patriarch and their caliphate. The Resch-Glutha, or Prince of the Captivity, lived in all the state and splendour of an oriental potentate, far outshining in his pomp his rival sovereign in Tiberias. The most celebrated of the rabbinical sovereigns was Jehuda, sometimes called the nasi or patriarch. His life was of such spotless purity that he was named the Holy. He was the author of a new constitution for the Jewish people, for he embodied in the celebrated Mischna all the authorised traditions of the schools and courts, and all the authorised interpretations of the Mosaic law. Both in the East and the West the Jews maintained their seclusion from the rest of the world. The great work called the Talmud, formed of the Mischna and the Gemara (or compilation of comments), was composed during a period of thirty years of profound peace for the masters of the Babylonian schools, under Persian rule. This remains a monumental token of learning and industry of the eastern Jewish rabbins of the third and fourth centuries.
