().
1. Ruler or dynast of the city of Amastris on the Euxine, contemporary with Antiochus Soter.
The citizens of Heracleia wished to purchase from him his sovereignty, as Amastris had
formerly belonged to them; but to this he refused to accede. He, however, soon after gave up
the city to Ariobarzanes, king of Pontus. (Memnon, 16, ed. Orelli.) Droysen (Hellenismus, vol. ii. p. 230) supposes this Eumenes to be the nephew of Philetaerus,
who afterwards became king of Pergamus [EUMENES I.]; but there do
snot seem any sufficient grounds for this identification.
