Leo is the Nemean Lion, which was killed by Hercules on one of the 12 labors he had to perform for killing his family. According to Greek mythology, the lion that terrorized the citizens had a hide that could not punctured by iron, bronze or stone. Having broken all of his weapons fighting the man-eating lion, Hercules finally strangled it to death and placed it in the heavens as one of his conquests.
