Hercules Pillarsof

Hercules, Pillars of, were said to have been set up by that hero in the course of the travels that accompanied his tenth labour. They are said to have been at Calpe and Abyla, on the opposite sides of the Straits of Gibraltar, these being the limits of his western wanderings. Different stories are told of their origin, one being that he formed them by tearing asunder the rocks, another that he erected them to support a bridge for the passage of Geryon's flocks, another that he placed them to narrow the straits and keep sea-monsters out of the Mediterranean. Other pillars claim the name.
