Callisto
Stop thinking about the hot chick from Xena. Callisto was a nymph of Artemis in Greek myth. She was one of Artemis’ favoured hunting companions, and was eventually turned into a bear and placed in the night sky.
As a follower of the virgin Artemis, Callisto vowed to remain celibate like her leader; if that isn’t commitment, what is? Zeus apparently took the nymph’s vow of celibacy as a personal challenge. In an attempt to bang the nymph and thus put the “nymph” in “nympho,” Zeus took on the appearance of Artemis. He lured Callisto into a hug and raped her. As soon as it was discovered that Callisto was preggers, Artemis, though initially livid, was able to eventually stay her wrath and forgive Callisto, as she couldn’t be held responsible for the King of the Gods’ almost cartoonishly-villainous lust. Hera, who was always pissed with her husband, convinced Artemis to punish Callisto by turning her into a bear. Many years later Callisto’s son Arcas was hunting and ran across his mother, still in bear form. Just before he killed her, Zeus plucked both mother and son and placed them in the sky. Hooray for… happy… endings?
Greek myths are my favorite.
