In Greek mythology, Tethys was a Titanessess and sea goddess who was both sister and wife of Oceanus. Together, they had the three-thousand Oceanids.

During the war against the Titans, Tethys raised Rhea, her god-child.

Hera was not please with the placement of Callisto and Arcas in the sky, as the constellations Ursa Major and Ursa Minor, so she asked her nurse, Tethys, to help. Tethys, a marine goddess, cursed the constellations to forever circle the sky and never drop below the horizon, hence explaining why they are circumpolar.
