Callisto

nymph
Καλλιστώ
Nymph transformed into the Great Bear

Callisto was a companion of Artemis who was seduced by Zeus and transformed into a bear — placed in the sky as Ursa Major, the Great Bear constellation.

The Myth

Callisto was a huntress devoted to Artemis's virginal band. Zeus, disguised as Artemis, seduced her. When her pregnancy was discovered, Artemis expelled her. Hera (or Artemis) transformed her into a bear. Her son Arcas, raised by others, nearly killed her while hunting. Zeus intervened, placing both among the stars: Callisto as Ursa Major and Arcas as Ursa Minor (or Arcturus). Hera, furious that her rival was honoured, asked Tethys to forbid the constellations from bathing in the ocean — which is why Ursa Major never sets below the horizon at Greek latitudes.
