Theia, also known as Euryphaessa, was a prominent Titaness in Greek mythology associated with light, radiance, and heavenly brilliance. She was the daughter of Gaia (Earth) and Uranus (Sky) and embodied the divine power that gave precious metals, gemstones, and gold their shimmering luster. Theia's name itself reflects her connection to vision and illumination, symbolizing clarity and enlightenment.
Theia married her brother Hyperion, the Titan of light, and together they bore three celestial deities: Helios (the Sun), Selene (the Moon), and Eos (the Dawn). Through these children, Theia’s influence extended across the heavens, playing a key role in the cycles of day and night. Helios illuminated the world by day, Selene governed the night, and Eos heralded the coming of dawn.
Theia’s connection to light also extended to human perception. Ancient Greeks believed her divine essence granted the ability to see by allowing light to pass through the eyes, a concept tied to early ideas about vision. Additionally, her association with gold, silver, and gems reflected her role as a goddess of brilliance and wealth.
While Theia’s presence in mythological narratives is limited, her symbolic influence was significant. As a figure representing radiance, beauty, and the celestial order, Theia played an essential role in shaping Greek mythology’s understanding of light and its connection to divine power.
