<Tr> <Th> Parents </Th> <Td> Gaia (Hesiod) or Aether and Gaia or Aether and Hemera or Nyx </Td> </Tr> <Tr> <Th> Roman equivalent </Th> <Td> Caelus </Td> </Tr> <P> Uranus (/ ˈjʊərənəs / or / jʊˈreɪnəs /; Ancient Greek Οὐρανός, Ouranos (oːranós) meaning "sky" or "heaven") was the primal Greek god personifying the sky . His name 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 . </P> <P> The most probable etymology traces the name to a Proto - Greek form * worsanós (Ϝορσανός) enlarged from * ṷorsó - (also found in Greek ouréō' to urinate', Sanskrit varṣá' rain', Hittite ṷarša -' fog, mist'). The basic Indo - European root is * ṷérs -' to rain, moisten' (also found in Greek eérsē' dew', Sanskrit várṣati' to rain', Avestan aiβi. varəšta' it rained on'), making Ouranos the' rainmaker' . A less likely etymology is a derivative with meaning' the one standing on high' from PIE * ṷérso - (cf . Sanskrit várṣman' height, top', Lithuanian viršùs' upper, highest seat', Russian verx' height, top'). Georges Dumézil's equation of Ouranos' name with that of the Vedic deity Váruṇa (Mitanni Aruna), god of the sky and waters, is etymologically untenable . </P>
