predict this era as the time of the return of Quetzalcoatl aka the "civilizing ones". They are referring to Atlanteans. There are other prophecies of "returns" during our time. That's the primary reason that I'm thinking Quetzalcoatl = Atlantis rising. I don't know if Plato predicted a rising/return. Edgar Cayce did.
In those days, the "Atlantic" ocean was not named as it is today.
As so often happens, Prof Santos intended to prove Atlantis theory wrong. He ended up convincing himself.
*Prof. Arysio Nunes Santos is a Nuclear Physicist with a Ph. D. in Nuclear Physics and a Free-Docency in Physical-Chemistry. In the course of his protracted professional career as a scientist, Prof. Santos also worked as a geologist and climatologist, disciplines he came to master, making substantial contributions to Ice Age Theory, particularly in what concerns Catastrophism and the reality of the Flood, the cataclysm which ultimately led to the demise of Atlantis-Eden.
Prof. Santos also wrote several other books and articles on Science and Engineering, as well as on arcane subjects such as Symbolism, Alchemy, the Holy Grail, Comparative Mythology and Religion, etc.. Pursuing these studies with a multi-disciplinary approach based on both the Exact and the Human Sciences, as well as the more traditional disciplines, the author finally managed to discover Atlantis’ true location; to prove its identity with Eden and the other traditional Paradises, and to reconstruct in detail the secret history of the Lost Continent described by Plato and several other ancient sages.
A gifted amateur linguist, Prof. Santos masters several tongues, including Greek, Latin, Sanskrit and Dravida, which are essential for the understanding of the ancient myths on Paradise and its destruction by the Universal Flood. This knowledge has enabled him to decipher Etruscan and Pelasgian, the languages of the predecessors of the Greeks and the Romans in the Mediterranean region. Prof. Santos traced these languages back to Sanskrit and Dravida, establishing an ineluctable connection with the East Indies, the true site of Atlantis.
