Amastris

Amastris (in Greek Aμαστρις; 306 - killed 284 BC), also called Amastrine, was the daughter of Oxyathres, the brother of the Persian king Darius III, was given by Alexander the Great in marriage to Craterus. But Craterus decided to marry Phila, the daughter of Antipater.

Later Amastris married Dionysius, tyrant of Heraclea Pontica, in Bithynia, 322 BC. After the death of Dionysius, in 306 BC, who left her guardian of their children, Clearchus, Oxyathres, and Amastris, she married Lysimachus, 302 BC. Lysimachus, however, abandoned her shortly afterwards, and married Arsinoe, the daughter of Ptolemy I Soter, king of Egypt; whereupon Amastris retired to Heraclea, which she governed in her own right. She also founded shortly after 300 BC a city called after her own name Amastris, on the sea-coast of Paphlagonia, by the fusion (synoecism) of the four smaller towns of Sesamus, Cromna, Cytorus and Tium, by conquering them. One of these towns, Tium, later regained its autonomy, but the other three remained part of the city of Amastris' territory.

She was drowned by her two sons about 284 BC.
