Plato wrote that Posidon’s son Gades was given the land nearest the Pillars of Hercules, that being the coastal region of Cadiz, and his brother Atlas based probably in the Atlas mountains of far northwestern Africa. Plato also wrote that the empire of Atlantis extended inside the Pillars of Hercules (Gibraltar) as far as Libya and the Tyrrhenian Sea (Italy/Atalya), outside too though not saying how far (actually up to the Dogger Bank in the North Sea where was the Frisians’ homeland Atland), so that he said that Atlantis was bigger than Libya and Asia combined meant the Mediterranean coastal sections of Libya and Asia, the coastal sections westward of Atlantis, plus the Atlantic coastal zones up to the North Sea.
