Hide this area Mythology

Callisto was a nymph who was associated with the goddess of the hunt, Artemis.

Callisto caught the eye of Zeus. Knowing that the maiden had taken a vow of chastity, Zeus resorted to deception to get at Callisto. He came to her disguised as Artemis. Seizing the opportunity Zeus raped her. The son of Callisto was named Arcas, meaning "bear", and he grew up to be a fine hunter himself.
