The name Thea is also of Greek origin. Thea (also written Theia) is the Greek goddess of light. She is the daughter of Ouranos (heaven) and Gaia (earth), the wife of Hyperion (Titan god of light), and mother of Helios (the sun), Eos (the dawn), and Selene (the moon). The name has two meanings because the English translation, Thea, is the same for both the Greek word “èÝá” which means “sight” and “èåÜ” which means “goddess.”.
