Tethys vs Uranus

A Titaness, daughter of Gaia and Uranus and wife of her brother Oceanus. Hesiod makes her mother of the world's rivers and of the three thousand Oceanid nymphs; in the Iliad Hera calls her 'mother Tethys' and recalls being raised in her house.

Tethys was among the children Gaia bore to Uranus, the generation of Titans that preceded the Olympians. She married her brother Oceanus and bore him the rivers and the Oceanid nymphs.

Tethys is one of the twelve Titans born to Gaia and Uranus. Paired with her brother Oceanus, the great river that encircles the earth, she becomes in Hesiod's *Theogony* the mother of all rivers (Nile, Alpheus, Scamander, and many more) and of the Oceanids, the three thousand nymphs of springs and streams.

Primordial personification of the Sky, born from and united with Gaia (Earth). Father of the Titans, Cyclopes, and Hecatoncheires, Uranus was castrated by his son Cronus, an act whose aftermath shaped the early generations of Greek gods.

Uranus was brought forth by Gaia alone, without a father, to be the starry Sky covering the Earth on every side. United with Gaia, he fathered the Titans, Cyclopes, and Hecatoncheires, but his cruelty toward these children led Gaia to arm Cronus with a sickle and have him castrate Uranus, ending his direct rule.

Uranus is the personified Sky, brought forth by Gaia alone to be her equal and to cover her on every side, providing "an ever-sure abiding-place for the blessed gods." United with Gaia, he fathered the twelve Titans, the three Cyclopes, and the three Hundred-Handed Ones, the Hecatoncheires.
