A more interesting section happens in Chapter 10, which describes a short biography as well as his death after Lysias takes control of the Empire as regent and Gorgias is appointed the new governor of Coele-Syria: Ptolemy, who was called Macron, took the lead in showing justice to the Jews because of the wrong that had been done to them, and attempted to maintain peaceful relations with them.
Unable to command the respect due to his office, he took poison and ended his life.Some passages refer to a "Ptolemy son of Dorymenes", who some scholars suggest may be the same person.
2 Maccabees 4 recounts a story that the corrupt High Priest Menelaus paid a bribe to Ptolemy son of Dorymenes, one of the king's advisors, to avoid punishment for his misdeeds.
[6] According to 1 Maccabees 3:38-39, Lysias selected Ptolemy son of Dorymenes, Nicanor, and Gorgias as commanders of the Seleucid force that would eventually fight in the Battle of Emmaus (c. 165 BCE).
Terence Mitford cites that the story of 2 Maccabees of Menelaus being accused and then bribing Ptolemy son of Dorymenes seems to take place around 170 BCE, which is a bit too soon for Macron to have defected and for Cyprus to have been conquered.
Having a three year "cooling off" period while the Seleucids made sure he was not going to defect back to the Ptolemies would be a reasonable move to make before placing him in a high position worthy of his experience.
