This fertile sky god is said to have descended nightly upon mother earth (Gaia) to impregnate her. For fear of being overthrown by his offspring, he would return them to Gaia's womb as soon as they were born. Finally, tired of unending childbirth, Gaia conspires with her son, Cronos, to fix old Uranus. Cronos hid within Gaia's vagina (Is this Freudian or what?) and waited for that evening's mating. When the opportunity arrived, he castrated his father with a sickle! The testicles, in turn, were thrown into the sea where, by one account, they begot the goddess of love, Aphrodite. (In case you haven't gotten the message, these folks were the original dysfunctional family!)
