4. Daughter of Antipater, and wife of Ptolemy, the son of Lagus. The period of her marriage is not mentioned by any ancient writer, but it is probable that it took place shortly after the partition of Triparadeisus, and the appointment of Antipater to the regency, B. C. 321. (See Droysen, Gesch. d. Nachfolger, p. 154.) She was the mother of three sons, viz. Ptolemy Ceraunus, Meleager, who succeeded his brother on the throne of Macedonia, and a third (whose name is not mentioned), put to death by Ptolemy Philadelphus (Paus. 1.7.1); and of two daughters, Ptolemais, afterwards married to Demetrius Poliorcetes (Plut. Demetr. 32, 46), and Lysandra, the wife of Agathocles, son of Lysimachus. (Paus. 1.9.6.) It appears, however, that Ptolemy, who, like all the other Greek princes of his day, allowed himself to have several wives at once, latterly neglected her for Berenice (Plut. Pyrrh. 4); and it was probably from resentment on this account, and for the preference shewn to the children of Berenice, that she withdrew from the court of Egypt. In 287 we find her residing at Miletus, where she welcomed Demetrius Poliorcetes, and gave him her daughter Ptolemais in marriage, at a time when such a step could not but be highly offensive to Ptolemy. (Plut. Demetr. 46.)
