Uranus (mythology), in Greek mythology, the god of the heavens and husband of Gaea, who personified the earth. Uranus was the father of the Titans, the Cyclopes, and the 100-handed giants. The Titans, led by their ruler, Cronus, dethroned and castrated Uranus. From the blood that fell upon the earth sprang the three Erinyes, or Furies, who avenge crimes of patricide and perjury. The severed genitals of Uranus fell into the sea, and from them emerged the goddess Aphrodite. Although Uranus may have been worshiped as a god by earlier inhabitants of Greece, he was never an object of worship for the Greeks of the historical period.
