Geryon

Geryon was the son of Chrysaor and the Oceanid Callirrhoë. Geryon was the king of Erytheia (Cadiz), in Spain. Geryon was a man or monster with three bodies, joined at the waist.

Geryon was the owner of cattle which was placed in the care of Eurytion, his herdsman. Orthus, a two-headed hound, guarded them. Orthus was the offspring of Typhon and Echidna, and was closely related to the more famous hound, Cerberus.

As one of his labours, Heracles had to fetch the cattle of Geryon. Heracles killed Orthus and the herdsman, and drove off the cattle. When Geryon found out about the killing and theft, Geryon pursued Heracles. Heracles killed Geryon at the River Anthemus.
