THEIA

In Greek mythology, 'Theia' (also written 'Thea' or 'Thia'), also called 'Euryphaessa' ("wide-shining"), was a Titan. The name ''Theia'' alone means simply "goddess"; ''Theia Euryphaessa'' brings overtones of extent (''eury-'') and brightness. With her brother and husband Hyperion, "mild-eyed Euryphaessa, the far-shining one" (Homeric Hymn to Helios) was the mother of Helios (the Sun), Selene (the Moon) and Eos (the Dawn).
Pindar praises Theia in his Fifth Isthmian ode:
:"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 not only to similar mother-of-the-sun goddesses like Phoebe and Leto, but perhaps also to more universalizing mother-figures like 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.
''Euryphaessa'' has been adopted for a species of Australian leafhoppers ''Dayus euryphaessa'' (Kirkaldy, 1907).
