Mythology of the Ursa Major constellation
The constellation is linked to Greek mythology on the woman named Calisto. Once Hera, the wife of Zeus, found out about his recent crush, she became jealous and turned Calisto into a bear. Trapped inside the bearskin, it was quite impossible to recognize this woman and its beauty. That was especially the case when her son Arcas went looking for her. Arcas was a love child of the two, and in order to protect him, Zeus sends both him and his mother away. However, when Hera turned his mother into the beast, Arcas almost killed her by accident. In order to avoid tragedy, Zeus placed both of them as constellations in the sky.
