Amastris

Amastris, also called Amastrine (Amastrine), the daughter of Oxyartes, the brother of Darius, was given by Alexander in marriage to Craterus. (Arrian. Anab. vii. 4.) Craterus having fallen in love with Phila, the daughter of Antipater, Amastris married Dionysius, tyrant of Heracleia, in Bithynia, B. C. 322. After he death of Dionysius, In B. C. 306, who left her guardian of their children, Clearchus, Oxyathres, and Amastris, she married Lysimachus, B. C. 302. Lysimachus, however, abandoned her shortly afterwards, and married Arsinoe, the daughter of Ptolemy Philadelphus ; whereupon Amastris retired to Heracleia, which she governed in her own right. She also founded a city, called after her own name, on the sea-coast of Paphlagonia. She was drowned by her two sons about B. C. 288. (Memnon, c. 4, 5 ; Diod. xx. 109.)
