Father of the Sun: Hyperion and the Line of Light-Bearing Titans

Hyperion was one of the twelve Titans, a son of Uranus and Gaia, and in Hesiod's Theogony he married his sister Theia and fathered three children who together governed the sky's light: Helios the sun, Selene the moon and Eos the dawn. His name is generally read as meaning something like the one who goes above or the high one, an apt title for a god whose whole identity is bound up with radiance and height rather than with any story of conflict or conquest. Hyperion himself has almost no independent narrative in surviving Greek literature. He does not feature as a combatant in the Titanomachy, he is given no separate cult story, and no surviving myth shows him acting on his own initiative the way Cronus, Oceanus or Themis each do in at least one episode. His entire mythological function is genealogical, explaining where the sun, moon and dawn came from by giving them a Titan father whose own defining trait, brightness, they each inherited and then, in the case of Helios especially, came to eclipse in every practical sense within Greek religious life. Later Greek astronomy occasionally preserved his name for the same reason, using Hyperionides, son of Hyperion, as a poetic patronymic for Helios well into the Hellenistic period, keeping the Titan present in literature purely as an ancestor's name attached to a far more actively worshipped son.
