Greek and Roman history recounts that Antiochus Epiphanes plotted deceit against Ptolemy Philopator, the son of Cleopatra his sister, of whom he was the uncle, and deprived him of the kingdom of Egypt; and after the death of Cleopatra, when Alanicus the eunuch, the tutor of Philometor, and Leneus governed Egypt and sought to recover Syria, which Antiochus had seized by betrayal, a battle arose between the uncle and the boy Ptolemy. And when they engaged between Pelusium and Mount Casius, the leaders of Ptolemy were defeated; but Antiochus, sparing the boy and pretending friendship, went up to Memphis, and there, according to the custom of Egypt, received the kingdom, and claiming to provide for the boy's affairs, with a small force he subdued all Egypt, and entered the abundant and most fertile cities, and did what neither his fathers nor his forefathers had done, as it is written of him in Daniel. For no one in the kingdom of Syria had so devastated Egypt, and he scattered all their wealth, and was so cunning that he overthrew by his deceit the wise counsels of those who were the boy's leaders.
