Hades was one of the many children of Cronus and Rhea. Because an oracle once predicted to Cronus that one of his offspring would defeat him and steal his throne, the Titan decided to swallow all of his children alive the moment they came into the world. Rhea who yearned for a baby of her own, soon grew tired of this and decided to fool her husband. After giving birth to her youngest son Zeus she wrapped a stone in a baby's blanket and gave it to Cronus to devour. She then quickly hid the infant safely away on the isle of Crete. Just as the Priestess promised, Zeus grew to manhood and returned to overthrow his father but not before giving him a potion that caused him vomit up the other siblings.
