Martin Pepper is an American geologist who is intent on demonstrating that Santorini was the site of Atlantis, claiming to have new supportive evidence. He had his ideas revealed in a History Channel programme, Atlantis Found, first aired on October 19th 2015(a) as part of their How the Earth Works series.
I found it interesting that the advertising blurb for the show never once mentions Plato!
Unsurprising, Jason Colavito, an Atlantis sceptic, offers a scathing critique of the two-hour show (b). However, the German website, Atlantisforschung, criticises(c) the selective manner in which Pepper chose excerpts from Plato, ignoring details that might conflict with Santorini being Atlantis.
For my part, I cannot accept the Santorini/Thera theory without a convincing explanation for where, in the 2nd millennium BC, the military of over a million, plus a civilian population lived, not to mention the elephants. There is also a small matter of a plain of Atlantis, 370x550km (230×345 miles); where was that? Then, for good measure we are missing “the mountains which surrounded it (that) were at that time celebrated as surpassing all that now exist in number, magnitude and beauty.” (Critias.118b). I think Pepper should try again.
