Plato was told and wrote that the Strait of Hercules (Gibraltar) was impassable to ship traffic because the submergence of Atlantis had ostensibly blocked that shipping passage between the Atlantic and Mediterranean seas, but Herodotus had previously written that the Celts lived beyond the Pillars of Hercules, with shiptrade of southern Spain (Tartessos) at that time for copper, gold, and silver, of which Plato, two generations later, must surely have been aware, so he obviously had self applied blinders on when he recorded the story of Atlantis from his friends Critias and Timaeus, with much of that story contradicting what he surely must have already known about ancient greek history, such as that described by his famous predecesor, the ”father of history,” Herodotus.
