Story Summary
Discover the eighth labor in Hercules and the Mares of Diomedes. Learn how the Greek hero tamed man-eating horses and delivered justice to a cruel Thracian king.
For his eighth labor, King Eurystheus commanded Hercules to capture the four savage mares of Diomedes, the King of Thrace. These were no ordinary horses; they were man-eating beasts, kept in iron chains and fed on the flesh of unsuspecting guests. Hercules sailed to Thrace with a small group of volunteers, including his young friend Abderus. They quickly overpowered the king's grooms and drove the horses toward the sea. However, Diomedes pursued them with an army. Hercules left Abderus to guard the mares while he went to fight the Thracians. During the battle, the mares tragically turned on Abderus and devoured him. Enraged by the loss of his friend, Hercules defeated the Thracian army and captured Diomedes. In a fit of poetic justice, Hercules fed the cruel king to his own horses. Once they had feasted on their master's flesh, the mares became strangely calm and docile. Hercules led them back to Tiryns to show Eurystheus, who eventually released them on Mount Olympus, where they were said to be killed by wild beasts.

“The cruel master was served as the final meal to the monsters he had made.”
Fun Fact
To honor his fallen companion Abderus, Hercules founded the city of Abdera in Thrace, which later became the home of the famous philosopher Democritus.
