Uranus ( or ;
Ancient Greek ,
Ouranos meaning "
sky" or "
heaven") was the primal
Greek god personifying the sky. His equivalent in
Roman mythology was
Caelus. In
Ancient Greek literature, Uranus or
Father Sky was the son and husband of
Gaia, Mother Earth. According to
Hesiod's
Theogony, Uranus was conceived by Gaia alone, but other sources cite
Aether as his father. Uranus and Gaia were the parents of the first generation of
Titans, and the 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.
