He had mares so wild and strong that they had to be fastened with iron chains. Their fodder was chiefly hay; but strangers who had the misfortune to come into the city were thrown before them, their flesh serving the animals as food. When Hercules arrived the first thing he did was to seize the inhuman king himself and after he had overpowered the keepers, throw him before his own mares. With this food the animals were satisfied and Hercules was able to drive them to the sea. But the Bistonians followed him with weapons, and Hercules was forced to turn and fight them. He gave the horses into the keeping of his beloved companion Abderus, the son of Mercury, and while Hercules was away the animals grew hungry again and devoured their keeper. Hercules, returning, was greatly grieved over this loss, and later founded a city in honor of Abderus, naming it after his lost friend. For the present he was content to master the mares and drive them without further mishap to Eurystheus. The latter consecrated the horses to Juno. Their descendants were very powerful, and the great king Alexander of Macedonia rode one of them. The Legend of the Eighth Labor of Hercules, the Mares of Diomedes
