The Periplus (Περίπλους) of Hanno the Navigator claims that he founded it on his journey of exploration beyond the Pillars of Hercules.
[3][4] The manuscript is a copy of another Greek work which translated the Punic original and is part of the Codex Palatines Graecus 398 which belongs to the Heidelberg University.
[3] According to Hanno, he founded the colony, the first of his journey, two days' sail past the Pillars of Hercules.
[5] Schoff, citing Karl Müller, identified it with the town of Mehedia, currently known as Mehdya.
[6] Hanno may have been deliberately vague about the location of colonies he founded to prevent enemies of Carthage from finding them.
