Uranus was the starry heaven, the canopy of the world, born of Gaia without father and made by her to be the cover under which she would bring forth the gods. Lying upon her, he begot upon her the twelve Titans, the three Cyclopes, and the three Hecatoncheires (the Hundred-Handed Ones). But Uranus hated his offspring, fearing them; as soon as each was born, he thrust them back into Gaia's body, that they might not see the light. Gaia groaned with the weight of her hidden children, and at last conspired with the youngest of the Titans, Cronus, to take revenge. She forged a sickle of grey adamant; she gave it to Cronus; and when Uranus next came down upon her in love, Cronus emerged from his hiding-place, cut off his father's genitals with the sickle, and threw them away into the sea behind him. The blood that fell upon the earth gave rise to the Erinyes, the Giants, and the ash-tree nymphs; the severed members, drifting on the sea, gave rise (in time and from the foam) to Aphrodite. So passed the first king of heaven, and Cronus assumed his father's throne; and Uranus, mutilated and unmanned, ceased to be a power in the world.

Curator’s note
What the sources say, and what later tradition added. The sources for this bay
Hesiod, Theogony 154–210, is the principal source. The myth of the castration of the sky-god by his son is one of the most striking in Greek tradition, and it has parallels — sometimes startlingly close — in the Hurrian-Hittite Song of Kumarbi (treated in Volume I), where Kumarbi castrates Anu the sky-god. The Hurrian source predates Hesiod by some six or seven centuries, and direct or indirect transmission through the Aegean contacts of the Mycenaean Bronze Age is the most plausible explanation; the case is one of the clearer instances of Near Eastern influence on early Greek cosmogony. Uranus had no cult in the Greek world; he was a cosmogonic figure only, the first king who ceded the throne and disappeared.
