Ptolemy V Epiphanes
From Seleucia on the Tigris he led a short expedition down the Persian Gulf against the Gerrhaeans of the Arabian coast (205 BC/204 BC). Antiochus seemed to have restored the Seleucid empire in the east, which earned him the title of "the Great" (Antiochos Megas). In 205/204 BC the infant Ptolemy V Epiphanes succeeded to the Egyptian throne, and Antiochus is said (notably by Polybius) to have concluded a secret pact with Philip V of Macedon for the partition of the Ptolemaic possessions. Under the terms of this pact, Macedon was to receive the Ptolemaic possessions around the Aegean Sea and Cyrene, while Antiochus would annex Cyprus and Egypt.
