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.

Carolina Bays

Combes, Michel-Alain (L)

Dr Michel-Alain Combes (1942- ) is a French amateur astronomer with a PhD in astronomy from theCombes Université Pierre et Marie Curie (Paris VI). For forty years he has studied impact catastrophism and published his views in his book, La Terre Bombardée (The Bombarded Earth). His extensive website(a) endeavours to combine history, myth and science and includes a reference to Atlantis, as well as a kind mention of this site. His book can also be read on his site (French).

Combes delivered a paper in English(b) to a 2008 Conference in Paris entitled; The Apocalypse of the Year 10,000 BC – Myth or Reality? This encounter may have created the Carolina Bays and destroyed Atlantis as proposed by Otto Muck.

Furthermore, it has also been linked to the onset of the mini ice age known as the Younger Dryas as described by Firestone, West and Warwick-Smith in their book The Cycle of Cosmic Catastrophes[0110].

In 1992, Asteroid ‘3446 Combes’ was named in his honor.

Palmer, Trevor (L)

Trevor Palmer (1944- ) is an English Professor of Biology now living in Scotland. Apart from his day-job of enzymology and the study of genetic disorders, which led to an interest in evolution, which in turn brought him to research catastrophism, he has written a number of books on these subjects, including Perilous Planet Earth[888],  which places today’s “concern about the threat to Earth from asteroids and comets within an historical context.” He devotes two chapters of this comprehensive work to the subject of Atlantis, in which he reviews (chap.13) some of the late 19th and early 20th century theories as well as more recent developments (chap.28) exposing many of the weaknesses in the arguments on offer.

While Palmer does not express any personal views on the subject, it is noteworthy that he wrote an introduction to the 2005 Barnes & Noble edition of Lewis Spence’s The History of Atlantis. After a brief look at Spence’s life, Palmer gives an overview of the principal strands of Atlantology today and concluded that many of the issues debated 80 years ago are still unresolved and for that reason Spence’s book continues to be worth studying.

Palmer wrote a short paper(a) in 1987 which he was cautiously sceptical of the Atlantis story, particularly the possibility that it was destroyed during the Late Pleistocene era, with which I concur. He also touched on the subject of the Carolina Bays, apparently adding support to the now discredited idea that they were created by wind action. I expect that he may have modified his views by now.

Leonard, R. Cedric

R. Cedric LeonardR. Cedric Leonard (1934- ) is from Oklahoma and has worked as an electronic technician, initially in the U.S. Navy and later in private industry, from which he retired in 1990. He has studied Comparative Religion, Sanskrit and Classical Greek and has a B.A. in Anthropology from the University of Oklahoma. He is also self-taught in Egyptian, Canaanite and Phoenician inscriptions. He has also speculated on the possibility of the Phoenician alphabet having its origins in Atlantis and possibility of a connection with the Glozel Tablets(c).

His Sanskrit studies led him to investigate stories of the vimanas or ancient Hindu flying machines. He has produced several books[130][131]and scientific papers on the subject of Atlantis and ancient India. He has also written on the existence of UFO’s in ancient Egypt(d), Mesopotamia(h) and the Bible[132], particularly the Book of Ezekiel(e). He has also written a paper(f) about archaeological mysteries in general.

However, in his 1979 book, Quest for Atlantis[0130], Leonard has suggested that the Kings of Atlantis were human-alien hybrids and that humans are the result of alien genetic experiments!!

Although retired, he still maintains his very interesting Atlantis website(a), which covers a range of subjects including connections between Cro-Magnon Man and ancient Egypt with Atlantis.

He locates Atlantis along The Mid-Atlantic Ridge and offers geological, mythological, linguistic and paleontological evidence to support this idea and for its destruction following worldwide catastrophes around 10000 BC. He has also written a paper(g) on the asteroid/comet impact around the same time, which created the Carolina Bays and its possible connection with the destruction of Atlantis. This encounter was brought to the notice of a wide audience by Richard Firestone and his colleagues by their book, The Cycle of Cosmic Catastrophes[0110].

Leonard himself recognises that his belief in prehistoric flying machines may lead some readers to dismiss his carefully thought out theory on Atlantis, but he is adamant that both existed. Nevertheless, it is fair to say that Leonard is one of the few writers on the subject who has produced original material to support the idea of Atlantis’ existence.

Some of Leonard’s work can be found plagiarised on the Internet, most blatantly by the artist, Charles Alexander Moffat(b).

Firestone, Richard


Richard Firestone together with his co-authors Allen West and Simon Warwick-Smith have written one of the most impressive accounts[110] of a cosmic collision that led to the extinction in North America of large mammals such as the mammoth and sabre-toothed tiger and the concurrent disappearance of the Clovis people at the end of the last Ice Age. Their impact theory also offers a credible explanation for the Carolina Bays. However, they propose that this collision had catastrophic global consequences. The three scientists are prepared to consider the possibility that Plato’s Atlantis story, however garbled, is related to the same episode[0110.328]..

Since the publication of their book some evidence(a) has emerged that would appear to conflict with their core thesis. This criticism appears to be gaining support according to a May 2011 report(b)(d). However, in September 2012 it was reported that further intensive investigation has revealed flaws in the evidence gathering of Firestone’s critics(f). The interdisciplinary team of scientists from seven U.S. institutions concluded that “a disregard of three critical protocols, including sorting samples by size, explains why a group challenging the theory of a North American meteor-impact event some 12,900 years ago failed to find iron- and silica-rich magnetic particles in the sites they investigated.”

Strong resistence to the Firestone claims continued into 2013 when the Royal Holloway and the Sandia National Laboratories along with 13 other universities across the United States and Europe mounted further challenges(g).

The waters were muddied further when it was revealed that Allen West was formerly known as Allen Whitt, who was convicted in California of posing as a state-licenced geologist(b) and fined $4,500! He legally changed his name in 2006. His respected co-authors were apparently unaware of his history and as a consequence of West’s central role in the data gathering, the hypothesis is considered by some to be tainted. This may be a case of shooting the messenger instead of the message, a view discussed at length on the Internet(e).A spirited defence of both West in particular and the theory of the team in general has also been written(c) and should be read in order to get a more balanced view of this particular controversy.

The core debate has rumbled on ever since. In July 2015 the University of California, Santa Barbara, released the results(h) of research, led by James Kennett, which again supported the impact theory and has narrowed the date to a 100-year range, sometime between 12,835 and 12,735 years ago.” 

*The battle has continued, apparently inconclusively, with more papers being published by all sides. July 2018 saw an update of the controversy published on the Science News website(i), with no sign of the war ending.*

Inspiration resulting from an interview with Firestone led Kevin Curran to a study that ended with the publication of Fall of a Thousand Suns[1113], in which he investigates the effect of extraterrestrial encounters on the development of early religious beliefs.











Collins, Andrew

Andrew collinsAndrew Collins was born in England in 1957. Over the past twenty years he has been investigating the possible existence of ancient advanced civilisations. He has written three books on the subject of pre-history[072][073][074]. His volume on Atlantis has been well received as an example of how the subject should be researched. Although Collins initially thought that Antarctica had been home to Atlantis he eventually concluded that Cuba was its location and provided a wealth of evidence to support this view in his book, Gateway to Atlantis. David Rohl, wrote a sympathetic Introduction for the book and repeated and expanded on his expressed views at a subsequent lecture(h).

Collins has recently written another controversial book[075], on the place of the constellation Cygnus in prehistoric consciousness. Arising from this study, it appears that the position of the Cygnus stars correlate more accurately with the Giza pyramids than those of Orion, which was proposed some years ago by Robert Bauval. Incredibly, a fifteen-year-old Canadian boy has produced a comparable theory(e) involving Mayan cities and a star map. The site proposed by him has now been identified, by people who personally know the location, as either an abandoned cornfield or a marijuana crop(f).*In 2018, Gustavo Muniz posted a number of videos on YouTube suggesting an Orion connection with a site in the Amazon Basin(i)!*

However, Collins has not been completely seduced by Bauval’s discovery and prudently remarks that the correlation may be just coincidence. Jason Colavito has written a brief critique(b) of this book.

In 2005 Collins published The Cygnus Mystery[075]in which he explored the significance of the Cygnus constellation in the ancient cultures of America, Egypt and Britain. Furthermore, in August 2013 he published a paper(c) with Rodney Hale suggesting that the Göbekli Tepe site is probably aligned with the star Deneb in the Cygnus constellation. This idea has now been expanded on in Collins’ 2014 book, Göbekli Tepe: Genesis of the Gods[0983], although his treatment has been heavily criticised as pseudoscience(g).

Collins has made some dramatic claims regarding the significance of Cygnus including the proposal that The veneration of Cygnus as a bird associated with cosmic life and death goes back 17,000 years to when the constellation occupied pole position in the northen night sky” and perhaps even more extreme, the idea that “Cygnus is at the root of all the world’s religions.”

Collins continues with the Cygnus-Giza connection in a subsequent offering Beneath the Pyramids[631]. This book reveals the tunnels and chambers beneath the Giza pyramids and their possible connection with the “Hall of Records” predicted by Edgar Cayce to be located there and due for discovery.

In a paper(d), co-authored with Rodney Hale, published in April 2016, Collins returned to the theory of a Cygnus-Giza correlation based on a master plan that they claim can now be demonstrated mathematically.

Collins has now moved on to new ground with his Lightquest[895], in which he attempts to offer a new explanation for the UFO phenomena. He claims that what have been described as UFOs are “the product of sentient light forms and light intelligences that co-exist with humanity, and have done so since time immemorial.”

Nevertheless, Collins returns to the subject of Atlantis with a new book, Atlantis in the Caribbean[1197], which is a revised version of Gateway to Atlantis. In it he  follows some of Otto Muck’s ideas and Explains how Atlantis was destroyed by a comet, the same comet that formed the mysterious Carolina Bays“.

When the Denisovans were recently identified as an extinct species of hominid, related to the Neanderthals It did not take long for speculative history enthusiasts to jump onboard this new bandwagon. Andrew Collins has now prepared The Cygnus Key[1509] for publication in 2018, in which he claims to present “compelling evidence showing that the earliest origins of human culture, religion, and technology derive from the Denisovans, the true creators of the lost civilization long known to exist but never before proved.Prior to the identification of the Denisovans, Colin Wilson had claimed that the Neanderthals “were the civilising force behind Atlantis”![0336]*One cannot help wondering if another early hominid species is discovered, which is quite possible, will they also be claimed as the progenitors of this ancient lost civilisation?

In this new book Collins alsoexplains how the stars of Cygnus coincided with the turning point of the heavens at the moment the Denisovan legacy was handed to the first human societies in southern Siberia some 45,000 years ago, catalyzing beliefs in swan ancestry and an understanding of Cygnus as the source of cosmic creation.”   Hmm.

Andrew Collins maintains a useful website(a) that has plenty of information on his books and lectures.    











Catastrophism today is the name given to a school of thought that supports the idea that the history of the Earth has been punctuated by natural events such as floods, fires and asteroid strikes that have caused widespread if not global devastation and that some of these events occurred within the memory of man and are recorded in worldwide mythologies.

Georges Cuvier (1768-1832) is sometimes referred to as ‘the father of paleontology’ and an early exponent of catastrophism.

Worryingly, it is now more generally accepted that further catastrophes will occur as a result of future cometary/asteroidal strikes. One such close encounter, around 2800 BC, was considered by the christian catastrophist, Donald W. Patten, to have generated the Deluge of Noah(j) and was the source of the flood legends found around the world! Patten nominates Mars as the intruder(l), an idea also advocated by Elsar Orkan, who, however, proposes a date of around 8000 BC for this encounter[1442].

Some readers may think that the subject has no direct connection with Plato’s Atlantis, however, his text refers to a number of catastrophic events that clearly brought devastation to Athens, Atlantis and beyond. The Flood of Deucalion and earlier inundations, Phaeton and other cosmic encounters, plus conflagrations and earthquakes all point to periods of great instability in the early prehistory of the Aegean region and quite probably much further afield.

Jürgen Spanuth devotes chapter 4 of his Atlantis of the North[0015] to an examination of “the natural catastrophes of the 13th century BC” that deals with Phaeton and the blizzard of floods, earthquakes and eruptions that beset the Eastern Mediterranean at the end of the 2nd millennium BC. Some of these matters have been recently expanded upon by Nur & Cline(f)(g) and endorsed by Stavros Papamarinopoulos[0750.73].

August 2013 saw studies published(h) which pointed the finger at climate change as the cause of the widespread political instability in that region during the second millennium BC.

Claude Schaeffer, a celebrated French archaeologist, declared in 1948[0806] that on at least five occasions during the Bronze Age the Middle East had been subjected to widespread catastrophic destruction as a result of natural events rather than human activity.

Immanuel Velikovsky is arguably the best know of the 20th century catastrophists, who published two books[0037][0038] in the 1950’s that provoked widespread controversy that continues today. There is an interesting albeit a sceptical review of catastrophism in the last century by Patrick Moore & Bob Forrest in Chapter 14 of More Things in Heaven and Earth.(k)

 Rene Gallant

René Gallant

In 1964, the Belgian mathematician René Gallant (1908-1985) published Bombarded Earth[0748 which dealt in great detail with the consequences of meterorite impacts with the earth. Gallant, perhaps because of his amateur status as a geologist, never received the attention he deserved.

More recently Allan & Delair produced another book[0014] that identified 9500 BC as the date of a global catastrophe following an encounter with a comet. Their conclusions are at variance with Velikovsky’s, particularly regarding dates. Professor Mike Baillie of Queens University, Belfast is a well-known dendrochronologist who has recently entered the debate with his book, Exodus to Arthur[0111] that adds evidence from his discipline to support the theory of cometary or asteroidal impacts with the Earth. Unfortunately his work is confined to the last 4,500 years and so casts no further light on the 9,500 BC date apart from offering support for the possibility of extraterrestrial impacts.

However, Richard Firestone and his co-authors have researched[0110] an impact ‘Event’ the occurred 13,000 years ago and caused devastation in North America including the creation of the hundreds of thousands of Carolina Bays and some of the outbursts of Lake Missoula. Like Baillie, they claim that a memory of this event has been preserved in the folktales of many of the North American Indians. This book is a must-read for anyone interested in the latest developments in catastrophist research.

The destruction of Atlantis has been linked to a number of possible catastrophic events including earthquakes, volcanic eruptions, floods and asteroid strikes. Plato’s account cites a flood as the immediate cause of the disappearance of Atlantis. In the 18th century Giovanni Carli was probably the first to link a cometary encounter with the Earth as the cause of Atlantis’ demise. This idea has been supported by numerous writers ever since with Emilio Spedicato being one of its leading exponents today.

There are numerous sites on the Internet relating to catastrophism of which one(a) can be recommended as a good starting point for further study. Andy Blackard has listed(b) events connected with global upheavals around 3200 and 2000 BC. An Australian archaeologist, Peter Jupp, is the creator of the Ancient Destructions website(e) which deals with a number of historical mysteries including, Baalbek and Antarctica.

A more recent book by Robert Argod[0065] postulates that many of these historical catastrophes were caused by an irregular series of accelerated tectonic movements, although he does not offer a credible mechanism to explain the triggering of such upheavals. Is it possible that the strikes by or near misses with extraterrestrial objects, proposed by so many, generated the tectonic shifts proposed by Argod?

Professor Trevor Palmer has written a comprehensive history of catastrophes and catastrophism from the earliest times and its relevance today. His Perilous Planet Earth[0888] includes a couple of chapters in which he reviews Atlantis theories in the context of catastrophism.

Dr Michel-Alain Combes has a PhD in astronomy from the Université Pierre et Marie Curie (Paris VI). He has an extensive website(i) dealing with catastrophism, which translates quite well.

2012 was been promoted as the date of the next worldwide catastrophe based on a highly questionable interpretation of the Mayan calendar. New Age gurus were promising a change in global consciousness, whatever that means. If interested  you can read more of this nonsense online(c) or consider a more balanced view(d).

A huge catastrophist bibliography is available online(m)

Carolina Bays

The Carolina Bays are named after the bay trees found growing in the 500,000 mysterious oval shaped depressions located in Georgia, the Carolinas and Virginia.

Their characteristics have been presented as evidence of impact damage from a comet or asteroid. This view is hotly disputed, as is Carolinasthe idea that they are of relatively recent origin at the beginning of the Holocene. Emilio Spedicato is one proponent who considers that a relatively recent impact to have been a contributory fact to the ending of the last Ice Age leading to the demise of Atlantis.

In 1976, Otto Muck was probably the first to suggest a link between the Carolina bays and Atlantis [098.154-158].

A more mundane explanation has been recently offered by Jon Pelletier, assistant professor of geosciences at the University of Arizona in Tucson. He has just published a paper on a series of uniformly shaped and oriented lakes on North Slope of Alaska. Pelletier has offered a credible ‘thaw slumping’ rationalisation for their annual growth. However, I have not seen his explanation for their existence in the first place. Pelletier’s explanation(a) for the Carolinas is based on the dissolving of the underlying limestone in a manner that generated lakes with a uniform orientation. Although he admitted that at that time (2005) his solution is “very speculative”.

The cometary explanation was given additional support in 2007 when a team of researchers from Oregon University outlined evidence that included the Carolinas, for the disintegration of a comet over Eastern Canada around 10900 BC. They claim that apart from the initiation of the Younger Dryas period, it caused widespread destruction across North America and also led to the disappearance of the Clovis culture. Further evidence supporting this view(b) was advanced by other academics in 2008.

*Nevertheless, there is also evidence from optically stimulated luminescence (OSL) dating that the bays were formed 80,000 -100,000 years BP, which conflicts with the YD date! My layman’s view is that after 80,000 year I would expect the bays to be much more eroded than they appear to be.*

A more recent paper(e) by Antonio Zamora offers an important new concept, namely that the ‘bays’ were created by a meteorite striking the Laurentide Ice Sheet that existed in the Great Lakes region, during the last Ice Age, which in turn produced an enormous hail of ice ejecta which rained down on the eastern seaboard of what is now the United States. In his conclusion he claims “that  the new model of slow-velocity impacts from ice ejecta resulting from a meteorite impact on the Laurentide ice sheet explains many of the characteristics of the Carolina Bays, including the lack of shock metamorphism and meteorite fragments.” Zamora has also published in 2012 an ebook entitled Meteorite Cluster Impacts[1120](f), and in his 2015 book, Solving the Mystery of the Carolina Bays[1121], he expands on his theory that the ‘Bays’ were created as a result of an extraterrestrial impact with the Laurentide Ice Sheet. He describes in great detail the mathematical basis for his views.

Zamora, has now had a new paper on the ‘Bay’ published in the peer-reviewed journal, Geomorphology(i), which may help to rekindle discussion on the subject. Although, in my opinion, they are not directly related to the Atlantis narrative, the existence of the Carolina Bays provide very obvious evidence of our catastrophic past.

Ralph Ellis believes that Zamora’s ‘blocks of ice’ ejecta created by the impact should be thought of instead as being more akin to softer ‘slushballs’(g)(h).

The serial sceptic, Paul Heinrich, claims(d) that there is dating evidence, which indicates varying dates for the creation of different Carolinas. The most recent popular work to discuss comprehensively, the origin as well as the conflicting dating evidence for the Carolinas, is The Cycle of Cosmic Catastrophes by Firestone, West and Warwick-Smith. This is an important book that is primarily concerned with a cosmic catastrophe that wiped out the North American mammoth along with other large animals at the same time that the Clovis People disappeared 13,000 years ago. This was also the time of the colder Younger Dryas period.


When the Russian investigator Leonard Kulik studied the Tunguska River area, over which a meteor/asteroid exploded in 1908, he discovered a number of neat oval bog holes that might offer support for either the impact theory or more improbably the theories of Pelletier.

Now, over a century after the Tunguska event, an Italian research team have concluded that it was an asteroid that struck the earth and that nearby Lake Cheko is the impact crater(c).

*In 2013 Gernot Spielvogel co-authored Sonnenbomben[1582] in which it is suggested that the Tunguska event was caused by a solar plasma ‘bomb’.*

Nevertheless, various theories are still under investigation, including serious consideration of the possibility of an alien spaceship explosion!(j)

Atlantis of the North (L)

Atlantis of the North [015] was the third book written by Dr Jürgen Spanuth on the subject of Atlantis. His first work[016] published in German, led to court action by Spanuth after being labelled ‘a peddler of lies’. The matter ended when his detractors, ten professors, admitted that their objections to his work were groundless.

Spanuth’s book controversially locates Atlantis in the North Sea near Helgoland and attributes its destruction to the consequences of widespread natural catastrophes that the world experienced in the 13th century BC. These disasters led to large-scale migrations, one of which was from Scandinavia into the Mediterranean where Spanuth insists that the migrants were known as the ‘Sea Peoples’, or as he calls them ‘North Sea Peoples’ and portrayed on the walls of the temple of Medinet Habu. He claims that there is considerable agreement between Plato’s Atlantis story and the carvings at Medinet Habu.

Furthermore, Spanuth identifies a cometary impact with the Earth as the cause of these upheavals. He claims that this impact is preserved in mythology as Phaëton by the Greeks and others as Typhon, Sekhmet, Anat, and Tistrya etc. Incidentally, the Carolina Bays visible today have been linked with this event.

It has been pointed out that much of the material used by Spanuth seems to have been drawn from the research archives of the Nazi Ahnenerbe-SS. The result is a closely argued work that is worth reading, however unacceptable the Heligoland location is now seen.

In 2015, Spanuth entered the world of controversy again when The Mystery of Atlantis Unravelled[0127]  was published by Amazon’s self-publishing department, CreateSpace, with a new title The Mystery of Atlantis and the author’s name changed to ‘John Lock’! This is simply a badly scanned copy, blatant plagiarism and possibly breach of copyright as Spanuth only died in the 1998!

Gateway to Atlantis (L)

Gateway to Atlantis [072] by Andrew Collins is one of the better books on the subject. It is a fully indexed and referenced work that clearly indicates the effort and depth of research that went GatewayToAtlantisinto producing it.

Collins was originally inclined to believe that the Antarctic had been the home to Atlantis but has gradually come to focus his attention on the Caribbean. He has trawled the classical writers for any possible reference to Atlantis and has concluded that all their considerable evidence points to the Atlantic and in particular the Caribbean as the location of Atlantis.

In order to explain the sudden destruction of Atlantis, Collins discusses the possibility of some kind of cometary or asteroidal impact being the culprit. He is inclined to see the Carolina Bays as remnants of this collision. His conclusions are closely mirrored by the views of Emilio Spedicato. More details can be found on Collin’s website(a).

Paul Jordan, an Atlantis sceptic, has written a critical review of Collins’s book in his Atlantis Syndrome[418] , part of which is now available online, spread over four papers(b).




The Secret of Atlantis

The Secret of Atlantis [098], by Otto Heinrich Muck (1892-1956), was published posthumously, in German, in 1976, followed two years later by an English translation by Fred Bradley.
muckMuck was a resolute proponent of the theory that Atlantis existed in the Caribbean and was destroyed following an encounter with an asteroid. He identifies two large submarine holes near Puerto Rico as being possibly caused by the primary impact and adds the existence of the Carolina Bays as a possible secondary result.
He goes further and declares that this event took place at 8pm on June 5th, 8498 BC. He has arrived at this specific date following a close study of the Mayan calendar and in particular the presumed starting date of the so-called ‘Long Count’. As Zhirov pointed out ‘this means that one hypothesis is built on another”.

Muck contends, that prior to this collision, the glaciation of Europe would not have occurred as it did, had the Gulf Stream been able to operate as it does today. However, he postulates that a large island had existed in the Atlantic that prevented this from happening but it was destroyed by his suggested impact date of 8498 BC. This gave us the Gulf Stream circulation we now know and raised the temperatures in the north Western Europe. It is worth considering that scientists today are predicting the possibility of the warm Gulf Stream shutting down again due to the rapid melting of the Greenland Ice Cap, ironically as a consequence of global warming. The possible consequences of such an event would be catastrophic for parts of North-Western Europe.

Muck also attempted to bolster his destroyed Atlantic island theory with an explanation for the enigmatic migration habits of European eels.

Overall, this is an interesting, if flawed, work. Any criticism today should be tempered by the fact that was written without the benefit of the discoveries of the forty years since its publication. In that brief time span at least three of the mainstays of his theory, the Gulf Stream, the eel enigma and the Carolina bays have been potentially undermined with alternative explanations.

Egerton Sykes suspected that the impact theories of Muck were founded on those of Frank A. Melton and William Schriever of the University of Oklahoma and William F. Prouty all of whom proposed an extraterrestrial intrusion as the cause of the Carolina Bays.
