Tethys
The great Titaness of the sea who nursed Hera and whose union with Oceanus produced all the world's rivers and springs.
The Myth of Tethys
Tethys was the wife of Oceanus and together they produced the three thousand Oceanids and every river god in the Greek world. She was the great nurse and nourisher, embodying the life-giving properties of water. When Hera was an infant during the Titanomachy, Rhea entrusted her to Tethys and Oceanus for safekeeping — a gesture that preserved the future queen of the gods from the chaos of cosmic war. Homer refers to Tethys and Oceanus as the origin of all the gods, a statement some scholars interpret as preserving an older cosmogony predating Hesiod's Chaos-centered creation. Tethys also intervened in stellar mythology: she forbade the constellation Callisto (Ursa Major) from bathing in the ocean, which is why the Great Bear never sets below the horizon in Greek latitudes — a poetic explanation for a circumpolar constellation.
Fun Fact
The Tethys Ocean — the prehistoric sea between the ancient continents — was named after her by geologist Eduard Suess.
