An A-Z Guide To The Search For Plato's Atlantis


Joining The Dots

Joining The Dots

I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato's own words, tempered with some critical thinking and a modicum of common sense.

Emilio Spedicato

Red Sea (m)

The Red Sea, also known as the Erythraean Sea lies between Egypt and Sudan in Africa and Saudi Arabia and Yemen in Asia.eafrica At the southern end lies the strait of Bab-el-Mandeb, considered by a few researchers as the location of the Pillars of Herakles.

The ‘Red’ is often attributed to the seasonal blooming of a red-coloured bacterium. Some academics think that the cardinal points were ascribed colours, ‘red’ being south! Emilio Spedicato, in his paper(a) on the location of the biblical Ophir, points out that pumice which is normal volcanic ejecta turns blood-red when mixed with seawater. Immediately to the south is the East Africa Rift, home to dozens of volcanoes, which when erupting may have had pumice dust blown towards the Red Sea!

*[Coincidentally, the presumed cradle of humanity is situated not too far from the Rift volcanoes and has drawn serious claims(b) that they may have had a part to play in the evolution of hominids!]*




Moon, The

The Moon has little connection with Plato’s Atlantis story apart from the more extreme speculations of some writers. One of the wildest is that the Atlanteans had established a research facility on the Moon(a), an idea rivalled by that of Alan Butler & Christopher Knight in their book, Who Built the Moon[0937], in which they propose that the Moon was ‘constructed’! This idea has now been revived by Rob Shelsky[1584].*In 1965, the Umland brothers[833] proposed that the Moon was a communications relay station for the Maya to make contact with their home planet!*

In 1970, Michael Vasin and Alexander Shcherbakov, of what was then the Soviet Academy of Sciences, advanced a hypothesis that the Moon is a spaceship created by unknown beings.(k) 

The idea that the Moon was to some extent hollow was given impetus in the 1970’s, when a study of moonquakes revealed that the Moon ‘rang like a bell’ (i). Now, nearly half a century later, Wallace Thornhill, a leading Electric Universe proponent, has endorsed the hollow Moon idea and seems sympathetic to the idea of a hollow earth. This was expressed at a recent EU conference and be viewed at the 40-minute mark of a YouTube video.(j)

The origins of the Moon have also been the subject of extensive controversy with one side claiming that it had been ‘captured’ moonby the earth, while the other extreme argues that it had been ‘expelled’ from our planet. The expulsion theory posits(b) that a collision with another celestial body tore material from the Earth, which in time became our Moon(h). Nils Olof Bergquist writing in the 1940’s supported the expulsion scenario and had his original Swedish book on the subject translated into English as The Moon Puzzle[0786].

The most radical of the captured moon school was Hanns Hörbiger, who proposed that there had been a series of Moon captures. Many of his ideas were adopted by H.S. Bellamy, who added that the capture of our current satellite had caused the destruction of Atlantis. Nikolay Bonev, the astronomer, caused a stir in 1961 when he expressed the view that our Moon had once been an independent planet(d) that had experienced violent volcanic eruptions that were powerful enough to have produced a ‘recoil’ effect, which nudged it towards our Earth’s orbit and was eventually captured as our satellite.

More recently Emilio Spedicato expressed similar ideas(c), claiming that material taken from another large extraterrestrial body around 9450 BC became our Moon, but that the event also led to the destruction of Atlantis.*Stuart L. Harris has proposed(m) that the planet Nibiru had a close encounter with our Earth in 9577 BC that resulted in the destruction of Atlantis, followed by another visit in 9417 BC during which it lost one of its satellites, which became our Moon!*

Gary Gilligan, the catastrophist, also supports the concept of moon capture but dated this event to as recent as 2000 BC(f) and then later advanced it to 1200 BC(g). Researcher, Mark Andrew commenting on Gilligan’s claims wrote that Although Gilligan promises more evidence to come, his theory has to contend with the varied evidence of an earlier Moon, including the earliest known written myth of the Moon’s death and rebirth, the epic poem Descent of Inanna (dating from 1750 BC), and also the oldest known map of the moon (dating from 2800 BC).”(l)

Unexpectedly, the orbital speed of the Moon appears to vary on its trip around the Earth(e).

*Italy seems to have an uncertain etymology; Thucydides claims that Italos, the Sicilian king gave his name to Italy, while more recently Emilio Spedicato(h) considers that ”the best derivation we believe to be the one proposed by the Italian nuclear engineer Felice Vinci (1998), in his monograph claiming a Baltic setting for the Homeric epic: he derives Italia from the rare Greek word aithalia, meaning the smoking one.” This is thought to be a reference to Italy’s many volcanoes.*

Italy today is comprised of territory south of the Alps on mainland Europe including a very large boot-shaped peninsula, plus Sicily, Sardinia and some smaller island groups, which along with the French island of Corsica virtually enclose the Tyrrhenian Sea.

The earliest proposal that Italy could be linked with Atlantis came from Angelo Mazzoldi in 1840 when he claimed that before Etruria, Italy had been home to Atlantis and dated its demise to 1986 BC. Mazzoldi expressed a form of hyperdiffusion that had his Italian Atlantis as the mother-culture which seeded the great civilisations of the eastern Mediterranean region(b).

Some of Mazzoldi’s views regarding ancient Italy were expanded on by later scholars such Camillo Ravioli, Ciro Nispi-Landi, Evelino Leonardi, Costantine Cattoi, Guido DiNardo and Giuseppe Brex. Ravioli sought to associate the Maltese island of Gozo with his proposed Atlantis in Italy.

The Italian region of Lazio, which includes Rome, has had a number of very ancient structures proposed as Atlantean; Monte Circeo (Leonardi), Arpino(a) (Cassaro). Another aspect of Italian prehistory is the story of Tirrenide, which was described as a westward extension of the Italian landmass into the Tyrhennian Sea during the last Ice Age, with a land bridge to a conjoined Sardinia and Corsica.. At the same time there were land links to Sicily and Malta, which were all destroyed as deglaciation took place.

Cent MedIt is surprising that so few researchers have commented on Italy’s part in Plato’s Atlantis narrative considering that he twice, without any ambiguity, informs us that the Atlantean domain extended as far as Tyrrhenia (modern Tuscany).

Crit.114c. So all these, themselves and their descendants, dwelt for many generations bearing rule over many other islands throughout the sea, and holding sway besides, as was previously stated, over the Mediterranean peoples as far as Egypt and Tuscany.    Tim.25a/b. Now in this island of Atlantis there existed a confederation of kings, of great and marvellous power, which held sway over all the island, and over many other islands also and parts of the continent; and, moreover, of the lands here within the Straits they ruled over Libya as far as Egypt, and over Europe as far as Tuscany. (Bury)

The quotation from Timaeus is most interesting because of its reference to a ‘continent’. Some have understandably but incorrectly claimed that this is a reference to America or Antarctica, when quite clearly it refers to southern Italy as part of the continent of Europe. Moreover, Herodotus is quite clear (4.42) that the ancient Greeks knew of only three continents, Europe, Asia and Libya.

Philo of Alexandria (20 BC-50 AD) in his On the Eternity of the World(g) wrote “Are you ignorant of the celebrated account which is given of that most sacred Sicilian strait, which in old times joined Sicily to the continent of Italy?” (v.139). The name ‘Italy’ was normally used in ancient times to describe the southern part of the peninsula(e). Some commentators think that Philo was quoting Theophrastus, Aristotle’s successor. This would push the custom of referring to Italy as a ‘continent’ back near to the time of Plato. More recently, Armin Wolf, the German historian, when writing about Scheria relates(f) that “Even today, when people from Sicily go to Calabria (southern Italy) they say they are going to the ‘continente’.” This continuing usage is further confirmed by a current travel site(d) and by author, Robert Fox[1168.141]. I suggest that Plato used the term in a similar fashion and can be seen as offering the most rational explanation for the use of the word ‘continent’ in Timaeus 25a.

When you consider that close to Italy are located the large islands of Sicily, Sardinia and Corsica, as well as smaller archipelagos such as the Egadi, Lipari and Maltese groups, the idea of Atlantis in the Central Mediterranean can be seen as highly compatible with Plato’s description.

If we accept that Plato stated unambiguously that the domain of Atlantis included at least part of southern Italy and also declared that Atlantis attacked from beyond the Pillars of Heracles, then this appellation could not be applied at that time to any location in the vicinity of the Strait of Gibraltar, but must have been further east, probably not too far from Atlantean Italy. This matches earlier alternative locations recorded by classical writers who placed the ‘Pillars’ at the straits of Messina or Sicily. I personally favour Messina, unless there is stronger evidence that some of the islands in or near the Strait of Sicily such as the Maltese or Pelagian Islands or Pantelleria were home to the ‘Pillars’.

Urban, Theodore L.,

Theodore L. Urban was the author of a paper(a) delivered to the Lancaster County Historical Society of Pennsylvania in 1897. In it he stated that “I not only advocate the Platonic theory of the island of Atlantis but claim that it had a veritable existence.” He then proceeded to deny that it had been completely destroyed and argued that the biblical Ophir was Atlantis, suggesting that it had been located in the Americas, which explained the three years that the round trip took.

*A few years ago Emilio Spedicato linked Ophir with an ancient gold mine in Tibet(b)!*

Casas, Bartolomé de las

BartolemeBartolomé de las Casas (1484-1566) was a Dominican friar who chronicled the excesses of the Spanish invaders of America. He renounced his earlier views about slavery and spent decades fighting it.

Casas was convinced of the reality of Atlantis, having being strongly influenced by Marsilio Ficino‘s commentary on Plato’s Atlantis narrative.

He also claimed that Columbus had been inspired by Plato’s story of Atlantis. However, S. P. Kershaw[1410.163] quoting from B. Keen[1500] notes that Columbus’ son, Ferdinand ”explicity stated that his father never showed any interest in Plato’s tale.”

Bartolomé himself saw America as Atlantis and in his History of the Indies (Historia de Las Indias)[1521] begun in 1527, he drew up a list of parallels to support his contention.

Emilio Spedicato, who supports Hispaniola as the location of Atlantis was struck by the fact that de la Casas’ description of island matched so many details in Plato’s depiction of Atlantis.



Nibiru was a Sumerian astronomical term used to describe a planetary body that periodically approached Earth. This account was hijacked by the late Zechariah Sitchin to construct his Planet X theory in which he claimed that this planet had an orbit which took it to the outer limits of the solar system returning every 3600 years to the vicinity of Earth. Sitchin claimed that during one of these visits some of its inhabitants came to earth and become the ‘gods’ of the Sumerians. However, Sitchin failed to explain how the inhabitants of this Planet X survived the lack of heat and light that it would have had to endure as it moved away from the proximity of the Sun. For us inhabitants of Earth a drop of just a few degrees is fatal.

However, Emilio Spedicato has a radically different and certainly more rational view of this Sumerian planet.  He ascribes a much shorter orbital period of 20 years to Nibiru and claims that close encounters with this planet as having had a dramatic physical effect on the prehistory of our planet including the capturing of our Moon, the destruction of Atlantis and later the biblical Exodus! His scenario has elements that can be traced to Velikovsky, Ackerman and Hörbiger.

Professor Spedicato’s November 2012 paper, From Nibiru to Tiamat, an Astronomic Scenario for Earliest Sumerian Cosmology, can be read or downloaded from the excellent Diffusion and Migration website(1). A number of his other papers can be found on the same website and are certainly worth studying.

In sharp contrast to the serious work of Spedicato, for the past couple of years we have been subjected to a barrage of silly articles(b) linking Nibiru with the promised 2012 global catastrophes ‘predicted’ by the Mayan calendar.

A debunking of both Sitchin’s scholarship and the existence of Nibiru has been offered by a number of sites(c).

*However, some people, such as David Meade (a pen-name) who describes himself as a ‘Christian numerologist’ predicted that Nibiru would collide with Earth on September 23, 2017! When this did not happen he moved the event to October, but again nothing happened. But he persisted and subsequently moved our demise to March 2018, then April, with a final suggestion for the year of between May and December(d).*







ROIPA is an acronym for the original Russian title of the Russian Society for the Study of Problems of Atlantis which is the leading association in the Russian Federation for the study of Atlantology.

It was formally established in 2003 although it has its roots in the early 1990’s. Since then it has organised three congresses of Atlantologists, published papers and books including its recent Cronos almanac. There is also an ongoing programme of lectures.

Alexander Voronin was the president of ROIPA and I had the pleasure of meeting him in Malta in 2011. Sadly, Alexander died November 6th 2012.

Membership of ROIPA is normally confined to Russian citizens, so I was greatly flattered when I was given honorary membership of the organisation in 2011.

In March 2014, I was contacted by the new president of ROIPA, George Nefediev, who informed me that the work of the society was back on track and has already held a conference in in December, 2013. They are currently developing a new website(a).

Later in 2014, ROIPA will publish the second edition of their Cronos ‘almanac’. It has a number of contributions by researchers frequently encountered in the pages of Atlantipedia, such as Emilio Spedicato and R. Cedric Leonard. Although it will be published in Russian, you can view the contents in English here. As you will see the subjects are wide-ranging and it is regrettable that the volume will not be available in English.

ROIPA is organising its fourth Congress on the 13-14 April 2015. All are welcome and contributions invited

(a) The theme of the Congress is Atlantology in the XXI century – Development Prospects and is seeking to have Atlantology recognised as a legitimate scientific discipline.

Italian Atlantology

Italian Atlantology can be traced back to the 16th century when Fracastoro, Garimberto and Ramusio, identified the Americas as Atlantis. In fact we should look to the 15th century when Ficino was the first to translate Plato’s entire works into Latin giving medieval Europe its first access to the complete Atlantis texts. Not much happened until 1788 when Carli attributed the destruction of Atlantis to a close encounter with a comet. In 1840, Angelo Mazzoldi proposed Italy as the location of  Atlantis and as the hyper-diffusionist mother culture of the great civilisations of the Eastern Mediterranean region. He was followed by others such as Giuseppe Brex(b).

Two years after Donnelly published his Atlantis in 1882  the Italian, D’Albertis followed him and opted for the Azores as the remains of Atlantis.

Not much developed in pre-war Italy apart from Russo’s journal which ran from 1930 until 1932. After the war other Atlantis journals was established by Gianni Belli in 1956 and Bettini in 1963. After that there was a wide range of theories advanced by Italian researchers. Spedicato located Atlantis in Hispaniola, Stecchini opted for São Tomé, Barbiero, who although Croatian by birth was an admiral in the Italian Navy nominated the Antarctic as the home of Atlantis before the Flem-Aths published their Antarctic ideas. Bulloni chose the Arctic, Pincherle identified the Mandaeans as the last of the Atlanteans and Monte links Thera with Tarshish.

In recent years the most widely reported Atlantis theory to emanate from Italy came from Sergio Frau who advocates Sardinia as the original Atlantis. However, this idea is not new having been promoted by Poddighe in 1982. Frau has subsequently been supported by other commentators such as Tozzi and Novo. I cannot help feeling that there might be a trace of nationalism underlying this theory, a suspicion that I have held regarding writers of other nationalities.

The latter end of the 20th century saw the development of the Internet which enabled the instant promotion of Atlantis theories, both silly and serious, to a global audience. Italy was no exception, where websites, such as Edicolaweb that are sympathetic to the exploration of historical mysteries emerged(a).

More recently, Marin, Minella & Schievenin had The Three Ages of Atlantis[972] published in 2014. This is an English translation of their original 2010 work. In it they suggest that Atlantis had originally existed in Antarctica and after its destruction survivors established two other Atlantises in South America and the Mediterranean. Perhaps more credible was the theory of Capuchin friar, Antonio Moro, who suggested in 2013 that Atlantis included Iberia, the south coast of France and the west coast of Italy!

Younger Dryas

Younger Dryas also known as Dryas III was a mini Ice Age that lasted from around 10,700 BC until around 9600 BC. It is named after a flower that flourished during this relatively short period. In Ireland the period is known as the Nahanagan Stadial and in Britain as the Loch Lomond Stadial. For about thirteen hundred years the glaciers had been slowly retreating until within a short time-span temperatures dropped and they began to advance again. The cause of this cooling is not absolutely clear. One view is that a sudden release into the North Atlantic of vast quantities of fresh water that had been contained by huge ice dams is assumed to have closed down the Gulf Stream, resulting in a twelve hundred year lowering of global temperatures. There is evidence that the change only took one or two decades. The same threat is said to exist today with the possibility of the melting of the Greenland ice cap.

The most recent theory, by Firestone, West and Warwick-Smith[110], links the onset of the Younger Dryas with the explosion of a comet over North America that led to the extinction of many species, the collapse of the Clovis culture(a)(b) as well as the creation of the Carolina Bays.

A 2014 paper(g) entitled Nanodiamond-Rich Layer Across Three Continents Consistent with Major Cosmic Impact at 12,800 Cal BP by Charles R. Kinzie et al, has developed further the idea of this event being associated with the Younger Dryas. In a similar vein is an article(h) from Megan Gannon.

*A recent application of archaeoastronomy by Martin Sweatman and Dimitrios Tsikritsis led them to conclude that the carved symbols at Göbekli Tepe recorded an encounter involving the explosion or impact of part of Encke’s Comet around 13,000 years ago, which triggered the Younger Dryas Event that provided the impetus for the Neolithic Revolution. Sweatman later expanded their work in his book Prehistory Decoded [1621].

Kevin A. & Patrick J. Casey maintain that a globally catastrophic event occurred 13,000 years ago(l). The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period. They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the work of Richard Firestone and his colleagues.

A completely different view is expressed in Rod (Carl) Martin’s latest book[1623], where he proposes that the Younger Dryas ended as a result of catastrophic event.*

In 2015 a paper constraining the impact date to within 100 years using Bayesian statistical analyses, now proposed as 12,835 -12,735 years ago(j).

Younger DryasCoincidentally, Professor Emilio Spedicato independently arrived at the conclusion that it was a cometary impact in the North Atlantic that was responsible for the Younger Dryas. Subsequently, when temperatures rose again it resulted in the flooding of vast areas of low-lying landmasses that in Spedicato’s opinion, included Atlantis, which he locates in Hispaniola.

Conflicting evidence regarding the possibility of the Younger Dryas being caused by such an impact is impartially outlined on the internet(c).

December 2014 saw Graham Hancock raising the issue of a cometary cause for the Younger Dryas and its possible association with ancient Egypt(f).

The November 2013 issue of the BBC Focus magazine (p.30) had a brief article on the impact theory, noting that the northern hemisphere saw a drop of as much as 15°C around 11,000BC. In the absence of a suitable impact crater there is still much scientific scepticism(d).

However in early 2017, further possible evidence of an impact at the start of the Younger Dryas was offered by a team led by Christopher Moore of the University of South Carolina, when they identified a distinct layer of platinum in the soil that coincided with the start of YD. Commenting on this anomaly Moore noted that “Platinum is very rare in the Earth’s crust, but it is common in asteroids and comets.”(i)

In early 2018, two papers were published online(k), reinforcing the YD impact theory and adding evidence that the event resulted in a conflagration that may have consumed ?10 million km2, or ?9% of Earth’s terrestrial biomass.”

Ice cores from Greenland indicate a further cooling period circa 6200 BC that may be related to the abandonment of many Neolithic settlements during this period. Other periods of abrupt climate change have been identified from 3800 BC to 3500 BC and 2800 BC to 2000 BC.

The fact that Plato’s apparent date for the demise of Atlantis, circa 9600 BC, roughly corresponds with the current, best estimate for the date of the Younger Dryas is interesting but unfortunately not conclusive proof of any direct connection. In the absence of any supportive archaeological evidence, a linkage between Atlantis and the Younger Dryas will have to remain a matter of faith rather than fact. Interesting but inconclusive.

Recent discoveries in northern Sudan of dozens of skeletons, the majority of whom were apparently killed by flint-tipped arrows, have led to the suggestion(e) they were the result of food shortages resulting from the Younger Dryas that in turn led to warfare over diminished food availability.

Spedicato, Emilio

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 Spedicato_foto_2004pursuits, 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 its demise of Atlantis with a direct asteroidal impact or a close encounter with a planet-sized body.

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?

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[326], 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.
