Christopher Columbus (1451-1506) is not known to have made any specific statements regarding Atlantis, but a number of commentators have suggested that he was not only aware of Plato’s story but had consulted charts, such as Toscanelli’s(a), that depicted a mid-Atlantic island. De Gomara was insistent that Columbus had read Plato’s Timaeus and Critias, while the historian, Bartolomé de las Casas (1484-1566), claimed that Plato’s story inspired Columbus to embark on his voyages of discovery!
The Flem-Aths in their Atlantis Beneath the Ice, which is a 2012 revised version of When the Sky Fell, begin the book with a reference to a memorandum sent by Charles Hapgood to President Eisenhower. In it Hapgood sought the president’s assistance in locating a map used by Columbus, which he believed to still exist in Spanish archives. This map was apparently used to produce the famed Piri Reis Map that allegedly depicts an ice-free Antarctica. The Columbus map was not found.
