Genealogy
Most Greeks considered Uranus to be primordial, and gave him no parentage, believing him to have been born from Chaos, the primal form of the universe. However, in Theogony, Hesiod claims Uranus to be the offspring of Gaia, the earth goddess. Alcman and Callimachus elaborate that Uranus was fathered by Aether, the god of heavenly light and the upper air. Under the influence of the philosophers, Cicero, in De Natura Deorum ("Concerning the Nature of the Gods"), claims that he was the offspring of the ancient gods Aether and Hemera, Air and Day. According to the Orphic Hymns, Uranus was the son of Nyx, the personification of night.
