Roman Civil War of Constantius Gallus In 350, Emperor
Constantius II was engaged in a campaign in the East against the
Sasanians. He was however forced to return to the West to counter the usurpation of
Magnentius, who had murdered Constantius' brother and colleague,
Constans. Constantius therefore appointed his cousin
Gallus Caesar of the East, on March 15, 351 at
Sirmium. Gallus arrived at
Antioch, his capital, on May 7 of that same year. During the period between the passage of Constantius in the West and the arrival of Gallus in the East, or immediately after the arrival of the Caesar in Antioch, the Jews revolted in
Palestine.
Hostilities in Galilee The rebellion was led by Isaac of Diocaesarea (also known as Isaac of Sepphoris), and had its epicentre in the town of
Diocaesarea (the Greco-Roman referent for Sepphoris).
Jerome records that the revolt began with a night assault on the Roman garrison, which was destroyed, and allowed the Jews to procure the necessary weapons. According to the 9th century author
Theophanes the Confessor subsequently the rebels killed the people of different ethnicities, pagan Greek
Hellenes and
Samaritans. He is the first author to make this claim.
Ursicinus' campaign In 351 or 352, Gallus sent his
magister equitum Ursicinus to forcefully put down the revolt.
Tiberias and
Diospolis, two of the cities conquered by the rebels, were almost destroyed, while Diocaesarea was razed to the ground.
Sozomen, when recalling these events, wrote: "The Jews of Diocæsarea (
Sepphoris) also took up arms and invaded the Roman garrisons in
Palestine and the neighboring territories, with the design of shaking off the Roman yoke. On hearing of their insurrection, Gallus Caesar, who was then in Antioch, sent troops against them, defeated them, and destroyed Diocæsarea." A
midrash suggests that Patricius was killed in the battle. ==Aftermath==
