Uranus was the first ruler of the Universe and the god of the Sky. Uranus was created by Gaia in order to surround and cover her, but soon he became her mate and together they produced the remaining twelve Titans, three Cyclops and three Hecatoncheires, hundred-handed creatures, which Uranus used to loathe.
Fearful of his children overthrowing him, Uranus he pushed his children back one by one into the womb of his wife Gaia. Every time this happened, Gaea was suffering over the loss of children more and more and felt outraged by this injustice; until one day, she decided to hand a sickle to her son Cronus, the youngest, but boldest of Gaea's children, giving him the order to castrate Uranus.
Cronus obeyed and at that night hid himself in his parents' bed; hence he managed to castrate his father while he was sleeping. The blood of Uranus then started splattering onto the earth, producing Erinyes (Furies), Giants, and Melian Nymphs. Afterwards Cronus threw his father's genitals into the sea of Paphos in Cyprus, around which foams developed, transforming slowly into Aphrodite, the greek goddess of Love.
