7. A daughter of Ptolemy Physcon and Cleopatra [No. 6], married first her brother Ptolemy VIII. Lathyrus, but was divorced from him by his mother, and fled into Syria, where she married Antiochus IX. Cyzicenus, who was then in arms against his brother Grypus, about B. C. 117, and successfully tampered with the latter's army. A battle took place, in which Cyzicenus was defeated; and she then fled to Antioch, which was besieged and taken by Grypus, and Cleopatra was surrendered by him to the vengeance of his wife Tryphaena, her own sister, who had her murdered in a temple in which she had taken refuge. (Just. 39.3.)
