He was to go to savage Thrace and there destroy the man-eating horses of King Diomedes; afterward he was to go amongst the dread women, the Amazons, daughters of Ares, the god of war, and take from their queen, Hippolyte, the girdle that Ares had given her; then he was to go to Crete and take from the keeping of King Minos the beautiful bull that Poseidon had given him; afterward he was to go to the Island of Erytheia and take away from Geryoneus, the monster that had three bodies instead of one, the herd of red cattle that the two-headed hound Orthus kept guard over; then he was to go to the Garden of the Hesperides, and from that garden he was to take the golden apples that Zeus had given to Hera for a marriage gift--where the Garden of the Hesperides was no mortal knew. So Heracles set out on a long and perilous quest. First he went to Thrace, that savage land that was ruled over by Diomedes, son of Ares, the war god. Heracles broke into the stable where the horses were; he caught three of them by their heads, and although they kicked and bit and trampled he forced them out of the stable and down to the seashore, where his companion, Abderus, waited for him. The screams of the fierce horses were heard by the men of Thrace, and they, with their king, came after Heracles. He left the horses in charge of Abderus while he fought the Thracians and their savage king. Heracles shot his deadly arrows amongst them, and then he fought with their king. He drove them from the seashore, and then he came back to where he had left Abderus with the fierce horses. They had thrown Abderus upon the ground, and they were trampling upon him. Heracles drew his bow and he shot the horses with the unerring arrows that were dipped with the gall of the Hydra he had slain. Screaming, the horses of King Diomedes raced toward the sea, but one fell and another fell, and then, as it came to the line of the foam, the third of the fierce horses fell. They were all slain with the unerring arrows. Then Heracles took up the body of his companion and he buried it with proper rights, and over it he raised a column. Afterward, around that column a city that bore the name of Heracles's friend was built. Then toward the Euxine Sea he went. There, where the River Themiscyra flows into the sea he saw the abodes of the Amazons. And upon the rocks and the steep place he saw the warrior women standing with drawn bows in their hands. Most dangerous did they seem to Heracles. He did not know how to approach them; he might shoot at them with his unerring arrows, but when his arrows were all shot away, the Amazons, from their steep places, might be able to kill him with the arrows from their bows.
