In "Greek mythology, Theia ("//; "Ancient Greek: Θεία Theía, sometimes rendered Thea, Théa or Thia), also called Euryphaessa "wide-shining", is a "Titaness. Her brother/consort is "Hyperion, a Titan and god of the "sun, and together they are the "parents of "Helios (the Sun), "Selene (the Moon), and "Eos (the Dawn).
The name Theia alone means simply "goddess" or "divine"; Theia Euryphaessa (Θεία Εὐρυφάεσσα) brings overtones of extent (εὐρύς, eurys, "wide", root: εὐρυ-/εὐρε-) and brightness (φάος, phaos, "light", root: φαεσ-).
"Hesiod's "Theogony gives her an equally primal origin, said to be the eldest daughter of "Gaia (Earth) and "Uranus (Sky). "Robert Graves also relates that later Theia is referred to as the cow-eyed "Euryphaessa who gave birth to "Helios in myths dating to "Classical Antiquity.
Once paired in later myths with her Titan brother "Hyperion as her husband, "mild-eyed Euryphaessa, the far-shining one" of the "Homeric Hymn to Helios, was said to be the mother of "Helios (the Sun), "Selene (the Moon), and "Eos (the Dawn).
"Mother of the Sun, Theia of many names, for your sake men honor gold as more powerful than anything else; and through the value you bestow on them, o queen, ships contending on the sea and yoked teams of horses in swift-whirling contests become marvels."
She seems here a goddess of glittering in particular and of glory in general, but Pindar's allusion to her as "Theia of many names" is telling, since it suggests assimilation, referring not only to similar mother-of-the-sun goddesses such as "Phoebe and "Leto, but perhaps also to more universalizing "mother-figures such as "Rhea and "Cybele.

Theia's mythological role as the mother of the Moon goddess "Selene is alluded to in the application of the name to a "hypothetical planet which, according to the "giant impact hypothesis, collided with the "Earth, resulting in the Moon's creation.
