The supremacy was thus left in the hands of Hyrcanus, or rather of his minister Antipater, who really ruled in his name. With prudent alacrity the wily Idumæan completely changed his tactics, and did everything in his power to promote the cause of Cæsar. Resolved to settle the disputes concerning the succession to the throne of Egypt, and determined to uphold the claims of Cleopatra, who had completely won his heart, this general embarked in a war, in which for some time he was exposed to great danger on account of the small number of his troops. Antipater seized the opportunity of displaying a prudent activity on his behalf. He assisted his ally, Mithridates, king of Pontus, in marching to his relief, he contributed to the reduction of Pelusium, he conciliated the Jews in Egypt, who had espoused the cause of the opposite party, and received wounds in almost every part of his body[71], while fighting on his behalf. Cæsar was not slow to declare his gratitude. Having brought the Egyptian war to a close B.C. 47, he conferred upon his friend the privileges of Roman citizenship, and at the same time at his request confirmed Hyrcanus in the high-priesthood[72]. But Antigonus, son of Aristobulus, now appeared before him, and breaking forth into the fiercest accusations against Antipater, charged him with cruelty towards himself, oppression of the Jews, and an insincere friendship for his patron. The Idumæan was equal to the occasion. Throwing open his vest, he exposed the numerous wounds he had received in Cæsar’s cause, and protested his innocence and fidelity. The Dictator could not resist such an appeal, appointed him procurator of Judæa, and granted him permission to restore the ruined fortifications of Jerusalem[73]. Having made these arrangements Cæsar marched through Syria towards Pontus, to attack Pharnaces, the son of Mithridates the Great, who had defeated one of his lieutenants. Antipater conducted him beyond the Syrian frontiers, and returning to Jerusalem, commenced rebuilding the walls which had been overthrown by Pompey. He then set out on a tour through the country, suppressing tumults, and exhorting all to submit to the rule of Hyrcanus; soon waxing bolder, and taking advantage of the indolence of his nominal sovereign, he appointed his eldest son Phasael military governor of Judæa, and conferred the tetrarchy of Galilee on his younger son Herod, afterwards Herod the Great.
