To shore up her legitimacy with her subjects, Berenice IV married Archelaos (reportedly a descendant of Mithridates VI of Pontus); however, the Romans— especially desperate financiers of Ptolemy XII such as Rabirius Postumus—were determined to restore Ptolemy XII. Pompey persuaded Aulus Gabinius, the Roman governor of Syria, to invade Egypt and restore Ptolemy XII, offering him 10,000 talents for the mission. Although it put him at odds with Roman law, Gabinius invaded Egypt in the spring of 55 BC by way of Hasmonean Judea; Hyrcanus II had Antipater the Idumaean, the father of Herod the Great, furnish the Roman-led army with supplies.
