بطليموس السادس
About 147 BC he returned to Syria with a force of Cretan mercenaries led by a man called Lasthenes, while Alexander Balas was occupied with a revolt in Cilicia. In 145 BC Ptolemy VI Philometor, king of Egypt, ostensibly in support of Alexander Balas, but he switched his support to Demetrius. Ptolemy sealed the alliance by divorcing his daughter Cleopatra Thea from Alexander and remarrying her to Demetrius. Shortly after, Antioch surrendered to the Egyptian forces and offered the kingship to Ptolemy VI. However, he insisted Demetrius would become king, believing that Rome would not tolerate the unification of Egypt and Syria. Ptolemy pledged to serve as "a tutor in goodness and a guide" to Demetrius II. He probably intended for Demetrius to serve as a puppet ruler.
