Mythology

In both Greek and Roman mythology, Uranus was the god of the heavens. He was the father of the Titans and the grandfather of the Olympian gods. According to myth, he and his mate, Gaea, ruled the world until he was overthrown by his son, Cronus (Roman name: Saturn). Armed with a sickle, Cronus castrated his father and threw his genitals into the ocean, from which the goddess Aphrodite (Roman name: Venus) allegedly sprung. After his untimely sterilization, he was cast out by Cronus, who then became king of the Titans and ruler of the world until he himself was overthrown by his son, Zeus (Roman name: Jupiter).
