Baby Hercules wrestling serptents, while his step mother and father look on, and his biological mother is in the next room in bed with her husband, and someone heats milk over the fire. "Hercules, the Latin equivalent of Heracles, was the son of Jupiter and Alcmene. His jealous stepmother, Juno, tried to murder the infant Hercules by putting a serpent in his cradle. Luckily for Hercules, he was born with great strength and killed the serpent. By the time Hercules was an adult, he had already killed a lion. Eventually, Juno drove Hercules insane. Due to his insanity, Hercules killed his wife, Megara, and their three children. Hercules exiled himself because of the shame that he had brought on himself through his lack of sanity."
