(Ἀρετή), daughter of the elder Dionysius and Aristomache. She was first married to Thearides, and upon his death to her uncle Dion, the brother of her mother Aristomache. After Dion had fled from Syracuse during the reign of the younger Dionysius, Arete was compelled by her brother to marry Timocrates, one of his friends; but she was again received by Dion as his wife, when he had obtained possession of Syracuse and expelled the younger Dionysius. After Dion's assassination, B. C. 353, Arete was imprisoned together with her mother, and brought forth a son while in confinement. Arete and Aristomache were subsequently liberated and kindly received by Hicetas, one of Dion's friends, but he was afterwards persuaded by the enemies of Dion to drown them. (Plut. Dio 6, 21, 51, 57, 58; Aelian, Ael. VH 12.47, who erroneously makes Arete the mother, and Aristomache the wife of Dion.)
