Primordial personification of the Sky, born from and united with Gaia (Earth). Father of the Titans, Cyclopes, and Hecatoncheires, Uranus was castrated by his son Cronus, an act whose aftermath shaped the early generations of Greek gods.
Uranus was brought forth by Gaia alone, without a father, to be the starry Sky covering the Earth on every side. United with Gaia, he fathered the Titans, Cyclopes, and Hecatoncheires, but his cruelty toward these children led Gaia to arm Cronus with a sickle and have him castrate Uranus, ending his direct rule.
Uranus is the personified Sky, brought forth by Gaia alone to be her equal and to cover her on every side, providing "an ever-sure abiding-place for the blessed gods." United with Gaia, he fathered the twelve Titans, the three Cyclopes, and the three Hundred-Handed Ones, the Hecatoncheires.
