Barsine was daughter of Artabazus, satrap of Hellespontine Phrygia, and wife of Mentor of Rhodes and after his death, Mentor's brother, Memnon. In 334 BC, the year of Alexander's invasion of Asia, she and her children were sent by Memnon to the king Darius III as hostages for his fidelity; and in the ensuing year, when Damascus was betrayed to the Macedonians, she fell into the hands of Alexander, by whom she became the mother of Heracles.
