Many great and wonderful deeds are recorded of your state in our histories. But one of them exceeds all the rest in greatness and valour. For these histories tell of a mighty power which unprovoked made an expedition against the whole of Europe and Asia, and to which your city put an end. This power came forth out of the Atlantic Ocean, for in those days the Atlantic was navigable; and there was an island situated in front of the straits which are by you called the Pillars of Heracles; the island was larger than Libya and Asia put together, and was the way to other islands, and from these you might pass to the whole of the opposite continent which surrounded the true ocean; for this sea which is within the Straits of Heracles is only a harbour, having a narrow entrance, but that other is a real sea, and the surrounding land may be most truly called a boundless continent.
Now in this island of Atlantis there was a great and wonderful empire which had rule over the whole island and several others, and over parts of the continent, and, furthermore, the men of Atlantis had subjected the parts of Libya within the columns of Heracles as far as Egypt, and of Europe as far as Tyrrhenia. This vast power, gathered into one, endeavoured to subdue at a blow our country and yours and the whole of the region within the straits; and then, Solon, your country shone forth, in the excellence of her virtue and strength, among all mankind. She was pre-eminent in courage and military skill, and was the leader of the Hellenes. And when the rest fell off from her, being compelled to stand alone, after having undergone the very extremity of danger, she defeated and triumphed over the invaders, and preserved from slavery those who were not yet subjugated, and generously liberated all the rest of us who dwell within the pillars. (Timaeus)
The story is reminiscent of what Athens did against the Persians in the early 5th century BCE, but the battle with Atlantis allegedly took place in the 8th or 9th millennium BCE. It would not take much of a historical scholar to know that Athens in 9,000 BCE was either uninhabited or was occupied by very primitive people. This fact would not have concerned Plato's readers because they would have understood that he was not giving them an historical account of a real city. To assume, as many believers in Atlantis do, that there is a parallel between Homer's Iliad and Odyssey and Plato's Critias and Timaeus is simply absurd. And those who think that just as Schliemann found Troy so too will we someday crack Plato's code and find Atlantis are drawing an analogy where they should be drawing the curtains. Plato's purpose was not to pass on stories, but to create stories to teach moral lessons. What can we expect next from these lost scholars? A search for the grave of Cecrops, the serpent-tailed first king of Athens? The discovery of the true trident of Poseidon?
Different seekers have located the mythical place in the mid-Atlantic, Cuba, the Andes, and dozens of other places. Some have equated ancient Thera with Atlantis. Thera is a volcanic Greek island in the Aegean Sea that was devastated by a volcanic eruption in 1625 BCE. Until then it had been associated with the Minoan civilization on Crete.
To many, however, Atlantis is not just a lost continent. It is a lost world. The Atlanteans were extraterrestrials who destroyed themselves with nuclear bombs or some other extraordinarily powerful device. Atlantis was a place of advanced civilization and technology. Lewis Spence, a Scottish mythologist who used "inspiration" instead of scientific methods, attributes Cro-Magnon cave paintings in Europe to displaced Atlanteans (Feder, 130). Helena Blavatsky and the theosophists of the late 19th century invented the notion that the Atlanteans had invented airplanes and explosives and grew extraterrestrial wheat. The theosophists also invented Mu, a lost continent in the Pacific Ocean. Psychic healer Edgar Cayce claimed to have had psychic knowledge of Atlantean texts which assisted him in his prophecies and cures. J.Z. Knight claims that Ramtha, the spirit she channels, is from Atlantis.
The serious investigator of the myth of Atlantis must read Ignatius Donnelly's Atlantis: the Antediluvian World (1882). In the spirit of von Däniken, Velikovsky and Sitchin, Donnelly assumes that Plato's myth is true history. Much of the popularity of the myth of Atlantis, however, must go to popular writers such J.V. Luce (The End of Atlantis, 1970) and Charles Berlitz, the man who popularized the Bermuda Triangle and the discovery of Noah's Ark. His Doomsday, 1999 A.D. (1981) comes complete with maps of Atlantis and drawings by J. Manson Valentine. Graham Hancock is doing much to keep alive this tradition of "alternative" and "speculative" history and archaeology which seeks a single source for ancient civilizations. Scientists and the BBC don't think too highly of Mr. Hancock's efforts.
These "alternative" archaeologists have credited the Atlanteans with teaching the Egyptians and the Mesoamericans how to build pyramids and how to write, etc., arguing similarly to von Däniken that ancient civilizations burst on the scene in a variety of different places on earth and have a common source. Atlanteans or aliens, either way the case can be made for a common source for ancient civilizations only if one selectively ignores the gradual and lengthy development of those societies. One must also ignore that the writing of the Egyptians is no clue to the writing of the Mayans, or vice-versa, and that the purpose of their pyramids was quite different. The Mesoamericans rarely buried anyone in their pyramids; they were primarily for religious rituals and sacrifices. The Egyptians used pyramids exclusively for tombs or monuments over tombs. Why would the aliens or Atlanteans not teach the same writing techniques to the two cultures? And why teach step building in Mesoamerica, a technique not favored by the Egyptians? If you ignore the failures of the early pyramid builders and ignore their obvious development over time, including the development of underground tombs with several chambers, then you might be able to persuade uncritical minds that Giza couldn't have occurred without alien intervention.
Finally, one should wonder, I suppose, if the Atlanteans were such technological geniuses who shared their wisdom with the world, why did Plato depict them as arrogant warmongers?
Unfortunately for the New Age Atlanteans, there is no credible and convincing archaeological or geological evidence for either Atlantis or Mu. That has not stopped hundreds of people from concocting theories to the contrary. To paraphrase Whitehead, the belief in Atlantis, the ancient and great civilization, is another footnote to Plato.
