Jason and the Argonauts sailed into the Black Sea which only about a century previously, at the time of Ogyges, had been joined by the risen world ocean (at the end of the Ice Age), the Argonauts having sailed up what was named the Dardanelles Strait, named after Dardanus, a greek king who helped found Troy, with his son Troas, but that city was not yet a major player when Jason sailed by, the city not even mentioned in that story from circa 1300 b.c.
When Troy was being built, so too was Kekropia, which later (circa 800 b.c.) would be named Athens, but known in the story of Jason and the Argonauts as Kekropia, the story mentioning the bronze age city, and the kekropian shore on the Aegean, but no mention of Athens, which Plato later would say was its name before the (end of ice age) Flood of Ogyges, that flood name not mentioned ‘though by Plato, but it was the same flood in reality of his Atlantis story, proven by the fact that he mentions Kekrops having been a “king of Athens” in the timeframe of the flooding of Atlantis (and much of Greece), when the Ice Age ended.
Plato aquiesced to the egyptian priests’ report to Solon that Atlantis (and much of Greece) went under 9,000 years before Solon’s time, but with Kekrops, Theseus, Erysichthon, and Erectheus, clearly indicated in the timeframe of his Atlantis story, I think he knew better, having also surely been aware of the tale of Jason and the Argonauts, when Athens was Kekropia, about a century after the Flood of Ogyges, of which he also was certainly aware. And how’d the Atlanteans and “Athenians” navigate during the Ice Age? See article #2 at http://IceAgeCivilizations.com, and http://genesisveracityfoundation.com.
