Phila (Greek: Φίλα; died 287 BC), daughter of Antipater, the regent of Macedonia, is celebrated by the ancient sources as one of the noblest and most virtuous women of the age in which she lived.
[3] Her marriage to Demetrius may have been as early as 319 BC;[4] according to Diodorus it had already happened in 315, when the remains of her previous husband were consigned to her care by Ariston, the friend of Eumenes.
She appears to have again returned to Cyprus, where, in 295 BC, she was besieged in Salamis by the king of Egypt Ptolemy I, and ultimately compelled to surrender, but was treated by him in the most honourable manner and sent together with her children in safety to Macedonia.
But when, in 287 BC, a sudden revolution once more precipitated Demetrius from the throne, Phila, unable to bear this unexpected reversal of fortunes and despairing of the future, took her own life at Cassandreia.
She left two children by Demetrius; Antigonus, surnamed Gonatas, who became king of Macedonia; and a daughter, Stratonice, married first to Seleucus I Nicator, and afterwards to his son Antiochus I Soter.
