Pausanias Description of Greece 1.6.8

[8] After the death of Antigonos, Ptolemy again reduced the Syrians and Cyprus, and also restored Pyrrhos to Thesprotia on the mainland. Cyrene rebelled; but Magas, the son of Berenikē (who was at this time married to Ptolemy) captured Cyrene in the fifth year of the rebellion. If this Ptolemy really was the son of Philip, son of Amyntas, he must have inherited from his father his madness [ tò epi-manes] for women, for, while wedded to Eurydikē, the daughter of Antipatros, although he had children he went into a state-of-passion [ erōs] for Berenikē, whom Antipatros had sent to Egypt with Eurydikē. Having conceived-a-passion [ erastheis] for this woman, he had children by her, and when his end drew near he left the kingdom of Egypt to Ptolemy (after whom the Athenians name their phulē) being the son of Berenikē and not of the daughter of Antipatros.
