The end of Atlantis?
That's what I was thinking.
It does make sense. If Pato or the ones who told him the story of Atlantis were off a few thousand years, then that would put the eruption on Santorini right in the time frame for the destruction of Atlantis.
It just makes sense.
If only the Greek government would permit an archeological research in the area. There may be lots to find underwater near Santorini.
Plato clearly puts Atlantis outside the Gates of Hercules and demonstrated a knowledge of true continents beyond Atlantis i.e. North America. This knowledge came from the priests of Eygpt according to him.
