Ivar Zapp is a former professor of design at the architecture school of Universidad de Costa Rica and co-author, with George Erikson, of Atlantis in America that links Atlantis with the ancient cultures of Central America.
Zapp gave a talk in 2005 in which he identified a location in southwest Costa Rica as the site of Plato’s Atlantis(b). The Amazon customer reviews are worth a look(a).
In 2012 Zapp revealed that he was planning to publish a second book, Babel Deciphered, which will reveal that a maritime civilisation existed globally thousands of years before the Greeks, Egyptians and Sumerians and that this civilisation created the world’s first language(c). It appears that so far he has not found a publisher.
Regarding Atlantis, the same report noted that Zapp commenting on the fall of Atlantis, “said that (it) was not the literal collapse of a continent into the ocean, but the collapse of knowledge that plunged the world into a dark age where people forgot the language and navigation techniques pioneered by a civilization in the Americas.”
