In Greek mythology the sun was personifie as Helios (pronounced /ˈhiliˌɑs/) (Greek: Ἥλιος, Latinized as Helius). Homer often calls him simply Titan or Hyperion, while Hesiod (Theogony 371) and the Homeric Hymn separate him as a son of the Titans Hyperion and Theia (Hesiod) or Euryphaessa (Homeric Hymn) and brother of the goddesses Selene, the moon, and Eos, the dawn. The names of these three were also the common Greek words for sun, moon and dawn.
