Giovanni Francesco Gemelli Careri (1651-1725) was a famous Italian ‘adventurer’ who travelled the world using public transport. After his first trip across Europe, he later decided to undertake an around-the-world journey, which took him five years and was recorded in a six-volume work entitled Giro Del Mondo. Volume VI is concerned with Mexico where Careri studied its pyramids that led to his conclusion that the early inhabitants of America and the ancient Egyptians were both descended from inhabitants of Atlantis. A 1700 edition of Volume VI is available online(a).
Emilio Spedicato (1945- ) was born in Milan. He graduated in physics and is now working in numerical analysis and applied mathematics. He has held a full professorship at Bergamo University since 1984. In addition to his more conventional academic pursuits, he also researches ‘non-standard models of planetary evolution and non-standard interpretation of myth and ancient religions.’
Spedicato has developed a list(a) of ‘54 theses for reconstructing Earth and human history during the catastrophic period 9500 to 700 BC’. This list is partly based on the work of Velikovsky, DeGrazia and Ackerman and is intended to be the basis of a larger work in book form. Some of his ideas will be seen as highly controversial such as the genetic manipulation of humans by extraterrestrial visitors. He locates the Garden of Eden and the ‘creation’ of Adam and Eve in the Hunza valley of modern Pakistan(e).
He ventured into further controversial territory with his support for an updated version of Hörbiger’s moon capture theory(f) and endorsement for pole shifts(g) after long periods of stability following encounters with large extraterrestrial bodies. He considers the last of these to have taken place in the 10th millennium BC.
Spedicato, in a series of papers delivered to the Atlantis Conference on Melos in 2005, linked the biblical Exodus with the Flood of Deucalion, which he dates as 1447 BC(d). He contended that these events were connected with the explosion of a large extraterrestrial body over Southern Denmark remembered in Greek tradition as Phaëton.
Atlantis has not escaped Spedicato’s attention and he has put forward the Caribbean island of Hispaniola as the home of Atlantis(b), specifically suggesting that Lake Enriquillo in the Cul-de-Sac Depression, which runs from Haiti across the border into the Dominican Republic. Spedicato accepts the possibility of the destruction of Atlantis around 9600 BC and has written an interesting paper(c) that links the demise of Atlantis with a direct asteroidal impact or a close encounter with a planet-sized body. Not without significance is the fact that Hispaniola is not submerged, in spite of the sea level rising hundreds of feet since the very early date proposed by Spedicato for the destruction of Atlantis, which should have sent it even deeper beneath the waves of the Caribbean.
Furthermore, leaving aside the question of submergence altogether, Spedicato does not explain how an Atlantis in the Caribbean could, in 9600 BC, have attacked Greece or Egypt, which did not exist as structured societies at that time.
Even more intriguing is why they would plan such a venture, considering a distance of 10,000 kilometers lay between them.
Spedicato has contributed at least a dozen papers to the Migration and Diffusion website including one on a possible Indian inspiration behind the Giza pyramid complex(h) as well as a paper(i) on the planet known to the Sumerians as Nibiru and today sometimes referred to as Planet X. He controversially claims that a close encounter with Nibiru around 9500 BC ended the last Ice Age and brought about the demise of Atlantis! A difficulty with that idea, is that if the encounter with Nibiru destroyed Atlantis AND ended the Ice Age how could the location where Atlantis was submerged still be marked by mud shoals 9,000 years later when sea levels had risen by 300-400 feet, as confirmed by Plato in Timeaus 25d?
*Another radical idea put forward by Spedicato was expressed in a paper delivered to the 2005 Atlantis Conference [629.411], in which he claimed that what he called ‘the ancestors of the Greeks’ had visited Canada. Based on his interpretation of excerpts from the writings of Plutarch, he specifies a region at the mouth of the St. Lawrence River as the point of contact. Manolis Koutlis goes further, suggesting that the Greeks had colonies there from 1500 BC until 1500 AD. Then in his book In the Shadow  he adds the even more extraordinary claim that Atlantis had been situated on an island at the entrance to the St. Lawrence!*
In 2010, Spedicato published Atlantide e L’Esodo (Atlantis and Exodus) which is currently being translated into English.
In February 2015 Spedicato published another paper(j) with the radical proposal that the alignment of the three main Giza pyramids was not intended to be a reflection of the three stars in Orion’s belt, as proposed by Gilbert & Bauval, but instead were more closely matched to the arrangement of three volcanoes on Mars! He claims that these volcanoes were visible from Earth during Mars periodic close encounters with our planet between 7000 BC and 700 BC, during a 54-year cycle.
Later in 2015 the prolific Spedicato published another paper(k) in which he linked Mayan catastrophes with those of Hesiod, Plato and the Bible.
Adrian Gilbert (1949- ) is the well-respected author of a number of books and television documentaries on what are considered ‘fringe’ subjects. He is probably best known for The Mayan Prophecies co-authored with Maurice Cotterell as well as The Orion Mystery co-authored with Robert Bauval. He has also studied connections between the Bible and astrology.
Influenced by the ‘prophecies’ of Edgar Cayce he believes that Atlantis, or at least part of it, had existed in the West Indies near Bimini and that following its final inundation around 10,500 BC he claims that refugees fled to the Yucatan Peninsula where they developed the Mayan civilisation. Gilbert’s principal interest is the Mayan calendar and the fact that it will reset to zero at midnight on the 21st December 2012. This coincides with the earlier views of the American archaeologist, Michael D. Coe, who wrote about the significance of 2012 as early as 1966 in his book, The Maya. However, he has suggested three different dates between Dec. 24 2011 and Jan 11 2013 in various editions of his book(c).
It is claimed that this date will coincide with catastrophic events that occur cyclically every 5,000 years. Many authors, such as Patrick Geryl have speculated on the nature of the calamities that this date may bring.
The Identity of the Atlanteans has produced a range of speculative suggestions nearly as extensive as that of the proposed locations for Plato’s lost island. However, it is highly probable that we already know who the Atlanteans were, but under a different name.
The list below includes some of the more popular suggestions and as such is not necessarily exhaustive. While researchers have proposed particular locations for Atlantis, not all have identified an archaeologically identified culture to go with their chosen location. The problem being that most of the places suggested have endured successive invasions over the millennia by different peoples.
It would seem therefore that the most fruitful approach to solving the problem of identifying the Atlanteans would be to first focus on trying to determine the date of the demise of Atlantis. This should reduce the number of possible candidates, making it easier to identify the Atlanteans.
A final point to consider, is that the historical Atlanteans were a military alliance, and as such may have included more than one or none of those listed here. The mythological Atlanteans, who included the five sets of male twins and their successors would be expected to share a common culture, wheras military coalitions are frequently more disparate.

When the Sky Fell: In Search of Atlantis , by Rand & Rose Flem-Ath, astounded the world when first published, with its bold claim that Antarctica was the home of Atlantis. The Flem-Aths were inspired by the analysis of ancient maps carried out by Charles Hapgood and his students, combined with his theory of earth crustal displacement, which they refer to as ‘mantle’ displacement. It prompted them to look again at Plato’s Atlantis tale in the light of an ice-free Antarctica. They studied the extinction of species around 9600 BC in addition to the high altitude development of agriculture around the planet at approximately the same time. They perceived clear evidence of a global catastrophe in the tenth millennium BC in worldwide myths. Taking Posnansky’s studies at Tiahuanaco and Schoch’s investigation of the Sphinx together with views of Bauval and Gilbert’s dating of the orientation of the Giza pyramids, the Flem-Aths feel that there is a prima facie case for claiming the existence of an advanced civilisation at least as early as the 10th millennium BC. However, it must be mentioned that the dating conclusions of Posnansky, Schoch, Bauval and Gilbert are all hotly disputed.
In 2009, When the Sky Fell was revised and republished as an e-book(a) with a modified sub-title. A new revised and expanded hardcopy edition, entitled Atlantis Beneath the Ice, was published in April 2012.
In November 2009, news came from Sweden(b) that the remains of ancient settlements had been discovered in the far north of the country near the border with Finland, that were radiocarbon dated to 9000 BC. This is totally at variance with accepted theory, which has the region completely covered by ice at that time. However, this new discovery would appear to support the idea of earth crustal displacement at the end of the last Ice Age as described by the Flem-Aths in their original book.
However, we must keep our feet on the ground and realise that while this new discovery may be evidence for crustal displacement, it does not add to the concept of Atlantis in Antarctica. I think we will have to find settlements in the southern polar region to confirm that theory.
*Subsequently, Rand teamed up with the late Colin Wilson as co-authors of The Atlantis Blueprint . The book only dealt with the idea of Atlantis in Antarctica in the first couple of chapters. , but then generally wandered off into other areas for the rest of the book. Some time later, Wilson abandoned his support for the Antarctic location and opted instead for Sarmast‘s proposed site off Cyprus.
