Theia

Theia is a name from Greek mythology, borne by a Titan associated with radiance and light. With Hyperion, she is the mother of Helios, Selene, and Eos, who represent the sun, moon, and dawn. That family places her within a mythological picture of the visible heavens and their changing light.

The name may be connected with the Greek word for goddess, though that derivation is not completely certain. Theia’s mythological identity is firmer than its exact etymology. The spelling also distinguishes it from Thea, which can follow several naming paths of its own. For parents drawn to Greek stories, Theia offers a specific figure and a rich celestial context rather than only a general classical sound.
