Princess of Argos; Zeus fell in love with Io and seduced her. To try to keep Hera from noticing he covered the world with a thick blanket of clouds. This backfired, arousing Hera's suspicions. Zeus did some quick thinking and changed Io's form from being a lovely maiden. So as the clouds dispersed Hera found Zeus standing next to a cow. Hera, knowing that this was a lie, asked to have the cow as a present. If Zeus had turned the offer down, he knew that it wouldve given up the truth. After giving the cow to Hera, she sent the cow away and arranged Argus Panoptes to watch over it. Since Argus had a hundred eyes and could have some of them sleep while others were awake. Despewrately needing to get Io back, Zeus sent Hermes to get her. After using his story telling skill to put Argus to skleep, he killed Argus and returned Io to Zeus.

Origin and Family

Io’s father is Peiren in the Catalogue of Women. Io also may be identical to Callithyia; who is the daughter of Peiranthus. This means that Io also may be the daughter of Peiranthus. After many years of wandering as a cow, Io was changed back into a human and she bore a child named Epaphus.



Io does not have any special powers but does have numerous landmarks named after her. There is the Ionian Sea and the Bosphorous Straight ( which means ford of the cow).
