Wall of Atlantis
Doug Fisher is the author of a forthcoming book The Atlantis Maps: The Rise of Atlantis and the Fall of a Paradigm in which he> identifies Atlantis as North and South America with the Plain described by Plato being the region of Mesopotamia, in northeast Argentina.< The book is still a work-in-progress, but four chapters are sometimes available online(a).
Fisher has published an illustrated paper on Graham Hancock’s website with the self-explanatory title of The Walls of Atlantis(b). His suggestion of a huge outer wall encircling the city of Atlantis has been disputed by Jim Allen, provoking further comments(c) from Fisher.
He has also criticised the methodology, which Allen used to place Atlantis on the Altiplano(d), while I question the credibility of both their theories.
Fisher’s book is now finished and due for publication in November 2018 with the new title of Maps, Myths & Paradigms. His old website is now closing and a new site(e) is in preparation to coincide with the publication of his book.
