Oronteus Finaeus (1494-1555) was a celebrated cartographer who produced a map in 1531 which is claimed by some that, like the Piri Reis Map, it depicts the coast of an ice-free Antarctica. Charles Hapgood rediscovered it in 1959(a) in the Library of Congress. This idea is then used to support the concept of the existence of a very early civilisation that was capable of sophisticated map making. It is then just a short step to name this civilisation ‘Atlantis’. Some, such as the Flem-Aths went further and actually nominated Antarctica as the home of Atlantis.
Robert Argod has used the Oronteus Finaeus Map to support his contention that the Polynesians had originated in Antarctica.
A more recent website(b), although not endorsing an Antarctic Atlantis, discusses some of these old maps in very great detail. The site is based on a number of chapters from a work-in-progress, The Atlantis Maps: The Rise of Atlantis and the Fall of a Paradigm by Doug Fisher. He identifies the Plain of Mesopotamia in Northern Argentina as the location of Atlantis.
