The Myth Behind the Constellation Ursa Minor

Ursa Minor, “The Little Bear” is often linked to Arcas, son of Zeus and Callisto.  To protect Callisto from the jealousy of Hera, Zeus disguises his paramour by turning her into a bear.  The boy is raised by Maia, the mother of Hermes.  Many years later Arcas has become a masterful hunter and comes upon his mother in bear form.  Callisto recognizes her son and tries to greet him but her words only come out as growls.  Arcus is about to kill her when Zeus, taking pity, turns him into a bear and places mother and son in the stars as Ursa Major and Ursa Minor.  In another version, Arcas is not turned into a bear and is placed in the sky as Boötes.
