Uranus (Ouranos) is the ancient Greek deity of the Heavens, the personification of the sky, the earliest supreme god, who was the father of Cronus (Saturn) and of the Cyclopes and Titans (predecessors of the Olympian gods). Uranus was jealous of the future power of his children and feared he would lose his rulership to them. He threw his children in the underworld to prevent this. At the instigation of Gaia, her son Cronus castrated his father and dethroned him. Uranus is the sky god and first ruler. He is the son of Gaea, who created him without help. He then became the husband of Gaea and together they had many offspring, including twelve of the Titans. His rule ended when Cronus, encouraged by Gaea, castrated him. He either died from the wound or withdrew from earth
