He had received the task to recover the herds of Geryon, which the shepherd Eurizione kept Eurizia island, bordering the West.
During the trip he had delivered to Libya by a multitude of monsters and, in memory of those companies, had erected two columns, on both sides of the Strait, Ceuta and on the opposite shore, near Gibraltar.
In fact, according to legend, when he passed from Africa to Spain and to the island of Cadiz, we built a high tower on which erected a statue facing east, with a key in his right hand as if opening a door on left hand engraved with the inscription "Here are the boundaries of Hercules" to indicate the limit of land impassable notes.
The ancient fables were greeted in cartography since the Middle Ages to the sixteenth century in many medieval planispheres the "pillars of Hercules" were located near the Strait, but as they penetrated the navigators in the Atlantic, the columns were moved up on the cards the lands reached for the latter, thus marking the boundaries of the known world.
