Hercules had a number of myths that were distinctly Roman. One of these is Hercules' defeat of Cacus, who was terrorizing the countryside of Rome. The hero was associated with the Aventine Hill through his son Aventinus. Mark Antony considered him a personal patron god, as did the emperor Commodus. Hercules received various forms of religious veneration, including as a deity concerned with children and childbirth, in part because of myths about his precocious infancy, and in part because he fathered countless children. Roman brides wore a special belt tied with the "knot of Hercules", which was supposed to be hard to untie.
