Theia

Theia (not to be confused with Thea) was a Titaness, the daughter of Uranus and Gaia. She is said to have borne Helios, Eos and Selene to Hyperion, and to have been the mother of the Cercopes by Oceanus.

Her name most obviously means 'goddess', but it could also mean 'swift', from theo, 'to fly', 'run'. Both interpretations would be suitable for her. She features in some stories as Euryphaëssa.
