"... Sarmast said the search for Atlantis would be based on a series of clues left by Plato, including a very detailed description of the island as it was told by an ancient Egyptian priest to Solon, who in turn brought the story to Greece ..."Wow.
Is he referring to the "very detailed description" that included the phrase "beyond the Pillars of Heracles?"
Presumably. When that was said, I expect it would be the same as if we were to say today, "Just north of New York." (and, there will come a time when the exact location of New York isn't known)
This location is always said to be the area of Gibralter. Could it refer to somewhere else, perhaps something near Egypt?
