THE MYTH OF URSA MINOR When Arcas, the son of Callisto was out hunting, he came across a bear. The bear looked Arcas straight in the eyes. Just as Arcas was about to kill the bear, Jupiter stopped him, claiming that the bear was his mother. Arcas was then transformed into a bear, and taken up into the sky with his mother. Angered by such an honor, Juno, the woman that made Callisto into a bear, went to Poseiden asking him to forbid the two from bathing in the sea. Because of Juno’s wish, Ursa Major, the mom, and Ursa Minor, Arcas, never dip below the horizon in the sky.
