Uranus (IPA: /ˈjʊərənəs, jʊˈreɪnəs/) is the Latinize form of Ouranos (Οὐρανός), the Greek word for sky. In Greek mythology Uranus (often cited as Ouranos), Father Sky is personified as the son and husband of Gaia, Mother Earth (Hesiod, Theogony). Uranus and Gaia were ancestors of most of the Greek gods, but no cult addressed directly to Uranus survived into Classical times, and Uranus does not appear among the usual themes of Greek painted pottery. Elemental Earth, Sky and Styx might be joined, however, in a solemn invocation in Homeric epic.
