Kevin Christopher is a confirmed sceptic, whose paper, Atlantis: No way, No How, No Where (a), is widely available on the internet. It is a lightweight offering, frequently quoting two of the most extreme location theories, such as, Bolivia and Antarctica as justification for his view that the Atlantis story is ‘entirely fictional’.
Christopher also questions the chain of transmission of the story, describing it as ‘tenuous’. But as I have pointed out elsewhere, if Plato had simply concocted the Atlantis tale, it is reasonable to expect that he would also have invented a more straightforward provenance. Consequently, any perceived difficulties in this regard, actually enhance the credibility of the narrative.
