The Myth of Callisto
Callisto was originally one of the nymphs with Artemis. Unfortunately for her, one night after a hunt she became pregnant with a child of Zeus. Despite her attempts to conceal this fact, Artemis eventually found out about it anyway. She was furious with Callisto, and proceeded to exile her from her band. When Callisto's son, Arcas, was born, Hera learned what her husband had done and changed Callisto into a bear. Eventually, Callisto was shot by her own son and became the Ursa Major constellation.
