Uranus
Uranus was the first ruler of the Universe and the god of the Sky. Uranus was created by Gaea in order to surround and cover her, but soon he became her mate and together they produced the remaining twelve Titans, three Cyclopes and three Hecatoncheires, hundred handed creatures, which Uranus used to loathe.
Fearful of his children overthrowing him, Uranus pushed his children one by one back into the womb of his wife Gaea. Every time this happened, Gaea was suffering over the loss of children and feeling outraged by this injustice. Until one day, she decided to hand an unbreakable 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 he 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 intoAphrodite, the Greek goddess of Love.
Soon after Cronus drove his father from power, he brought back his brothers from the Tartarus and was crowned as the supreme ruler of the World.
