Talmudic literature, throughout all its chronological phases, relates to various Roman emperors. Nine emperors are mentioned explicitly by name, and among these are six who are especially notable, from three different periods. First, the period of the major Jewish revolts: Vespasian and Titus are mentioned for the War of the Destruction of the Temple, Trajan for the Diaspora revolts and Hadrian for the Bar Kochba Revolt. These are the “wicked” emperors of Talmudic literature, with Hadrian presented as the worst of all. Second, the golden age of relations between Judaea and Rome in the Severan period: “Antoninus,” usually identified with Caracalla, is presented as the “good” emperor par excellence. Finally, in the middle of the scale between the “wicked” and the “good” emperors we find Diocletian, the interesting emperor whose presence is strongly felt, as he was responsible for the development of the whole region.
