Diomedes of Thrace
In Greek mythology, King Diomedes of Thrace (Ancient Greek: Διομήδης) was the son of Ares and Cyrene. He lived on the shores of the Black Sea ruling the warlike tribe of Bistones. He is known for his man-eating horses, which Heracles stole in order to complete the eighth of his Twelve Labours, slaying Diomedes in the process.
