Crisp, Dan
Dan Crisp is the author of a paper(a) on the Graham Hancock website in which he endeavours to indicate the location of Atlantis. Based on a number of assumptions he concluded that “the kingdoms of Atlantis stretched from southern Spain, at the Pillars of Heracles, northwards along the continental shelf, skirting around the British Isles, as far as Scandinavia; with the great plain and capital city on the Celtic Shelf.”
As I find it difficult to subscribe to all of his assumptions, I cannot agree with his conclusion. However, Crisp should be applauded for his logical approach to the Atlantis problem*but, his interpretation of Plato’s Atlantis location clues must be challenged.*
