Hercules the Hero
MythologyThis is an old constellation, the Phoenicians called it their god Melkarth, the Greeks called it the Phantom. We know it most commonly as Hercules, the hero who had 12 labors to perform to demonstrate his courage and heroism. Hercules death was a sad story, we are told that our hero put on a tunic that contained a deadly poison. So tortured by this he was that he climbed a mountain, built a funeral pyre and perished in its fires. Jupiter was so touched by this that he had a cloud descend to Hercules, pick him up and carry him to his place in the sky.
