A triple-headed1 or triple-bodied2 giant, the king of Hesperia, who lived on the mythical island of Erytheia. He is the son of Chrysaor and Callirrhoe. Geryon possessed a fabulous herd of red oxen, which fed together with those of Hades, and which were guarded by the shepherd Eurytion and a two-headed dog named Orthrus.
Heracles, on the tenth of his Twelve Labors, killed all three and made off with the herds. See Cattle of Geryon.
