Enyo was one of the three sisters known as the Graeae. They shared one eye between them. When they briefly lost the eye and it was found by Hercules, the Graeae cast spells on Jason and Iolaus to try to convince Hercules to give the eye back. Jason was turned into a boar, and Iolaus was cursed to be attacked by all plants. Eventually, Hercules returned the eye to the sisters.
