Heracles’ Stealing of the Flesh-Eating Mares of Diomedes
As his eighth labor, Heracles was sent to Thrace to capture the four man-eating mares of King Diomedes. After a fierce battle with the King's army and the tragic loss of his companion Abderus, Heracles tamed the beasts by feeding them their own cruel master. The hero then founded the city of Abdera in honor of his fallen friend before delivering the horses to King Eurystheus.
