Source Verification: Theia
Every claim below is either what a named ancient source attests, in its own line or section, or a point where the sources themselves disagree.
What the Sources Attest
Who are Theia's parents and siblings?
Hesiod names her as one of the twelve Titans born to Ouranos and Gaia, making her a sibling of Kronos, Rhea, Oceanus, Hyperion, and the rest of that first generation, all born before the Olympians existed.
Source: Hesiod, Theogony 132-138
Who did Theia marry, and what children did she have?
She married her own brother, the Titan Hyperion, a common pattern among the first generation of Titans. Together they had three children who between them account for most of the sky's light: Helios the sun, Selene the moon, and Eos the dawn.
Source: Hesiod, Theogony 371-374
Does Theia have any myths of her own, separate from her children?
No meaningful ones survive. Every substantial reference to her in Hesiod exists to introduce Helios, Selene, and Eos - unlike Titans such as Kronos or Rhea, who act directly in the succession myth, Theia's entire recorded significance runs through what she gave birth to rather than anything she does herself.
Source: Hesiod, Theogony 371-374
Do other ancient sources besides Hesiod confirm Theia's place among the Titans?
Yes. Apollodorus's Library opens with its own summary of Ouranos and Gaia's children and names Theia directly among the Titan daughters, alongside Tethys, Rhea, Themis, Mnemosyne, and Phoebe, matching Hesiod's earlier list.
