Name and Etymology

The name “Theia” is derived from the ancient Greek word Θεία, which translates to “goddess” or “divine.” It’s a fitting title for a deity who personifies the divine light that illuminates the world. In some texts, she’s also referred to as “Euryphaessa,” a name that means “wide-shining.” This epithet further underscores her association with brilliance and luminosity.

In Roman mythology, there isn’t a direct counterpart to Theia. While the Romans had their own pantheon of gods and goddesses, not every Greek deity had a Roman equivalent. Theia’s unique position in Greek mythology, particularly her association with the celestial luminaries, sets her apart.

Her titles and names emphasize her radiant nature. As the mother of the Sun, Moon, and Dawn, Theia’s legacy is intrinsically tied to the cycles of day and night, light and darkness. Her influence is felt every time the sun rises, casting its golden hue, and every time the moonlight bathes the world in its silvery glow.

Theia’s Family and Childhood

Born to the primordial deities Uranus (Sky) and Gaia (Earth), Theia was one of the twelve Titans, a group of elder gods that preceded the Olympians. The Titans were the second generation of divine beings, coming after the primordials and before the Olympian gods and goddesses. Growing up, Theia was surrounded by her Titan siblings, each holding dominion over various aspects of the cosmos.

Her union with her brother Hyperion, the Titan of heavenly light, produced three significant offspring: Helios (the Sun), Selene (the Moon), and Eos (the Dawn). This union fortified Theia’s association with light and brightness, as her children became the primary luminaries that governed the day and night.

Not much is detailed about Theia’s childhood or early years in most ancient texts. However, given her lineage and the prominence of her siblings and offspring, it’s clear that she held a significant position within the Titan hierarchy. Her legacy, as we’ll see, is deeply intertwined with the celestial dance of light and darkness.

Theia’s Lovers and Relationships

The most notable relationship of Theia is with her brother Hyperion. Their union is a testament to the ancient practice among gods to marry close relatives, ensuring that their divine attributes and powers remained within the family. This relationship was not only significant in terms of their offspring but also symbolized the union of different aspects of light, with Theia representing the clear blue sky’s shining light and Hyperion embodying the light of the heavens.

Their bond was one of mutual respect and shared responsibilities. While Theia was the embodiment of the sky’s light, Hyperion was often depicted as the pillar of the east, holding the sky aloft. Together, they ensured that the world was illuminated, bringing forth the day and retreating for the night.

Theia’s Offspring

Theia’s union with Hyperion produced three iconic figures in Greek mythology: Helios, the sun god, Selene, the goddess of the moon, and Eos. Each of these deities played a pivotal role in the ancient Greeks’ understanding of time, light, and the celestial cycles.


Helios, often depicted with a radiant crown, was the personification of the Sun. Every morning, he would ride his golden chariot across the sky, bringing daylight to the world. In the evening, he would descend into the west, making way for the night. Helios was not just a passive sun-god; he was also a witness to events on Earth, often invoked by mortals and gods alike for his all-seeing nature.


Selene, goddess of the Moon, was often shown with a crescent moon crown, driving a silver chariot with white horses. She governed the night, her soft luminescence contrasting with the bright light of her brother Helios. Selene had several love interests and children. However, perhaps her most famous tale is her love for the mortal Endymion, The Mortal Loved by the Moon Goddess. She wished eternal sleep for him, so she could watch over him every night, leaving him sadly trapped in a never ending slumber.


Eos, the rosy-fingered goddess of the Dawn, heralded the arrival of her brother Helios each morning. She would rise from the east, casting away the darkness and bringing forth the first light. Eos had a penchant for falling in love with mortals, leading to several tales of passion and heartbreak.
