Le Plongeon asserts, based upon the writings of Plutarch, that Psenophis and Sonchis—one a priest of Heliopolis, the other of Sais—told the Athenian legislator at Solon, that 9,000 years before his visit to Egypt, on account of the submergence of the Island of Atlantis (the Land of Mu) that all communications had been interrupted with the Western countries (the Mayas). The author explores the cosmological parallels between the monuments, language and writing systems of the Maya and the Egyptians.
