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.

Harris, Stuart L.

Stuart L. Harris is an American researcher, self-described as an linguist, historian and archaeologist. He has contributed over eighty papers to the Migration & Diffusion website(a) and dozens to the site(b). He has touched on a wide variety of subjects; from Comet Encke to Glozel and Newgrange to Noah’s Flood. Although I am not a linguist, I think that that Harris’ penchant for ‘finding’ evidence of the Finnish language in locations as far apart as Dacia, Gaul, Teotihuacan and Hawaii is highly questionable, but I shall leave it to others, more skilled than I, to comment.

Inspired by Felice Vinci, Harris has promoted the idea of Troy in Finland, but until lately he had not directly addressed the question of Atlantis, but in recent private correspondence with me, he has claimed that Plato’s lost island had been situated in the vicinity of Rockall and destroyed around 9577 BC.*He later published these ideas in a paper on the website(c) in which he proposed that a close encounter with Nibiru that resulted in a number of its satellites impacting the Earth, causing devastation which included the demise of Atlantis. The article contains a lot of wild speculations including the suggestion that Nibiru on a return to Earth in 9417 BC, lost another of its satellites, which became our Moon!*




Mzora Stone Circle

The Mzora Stone Circle is a huge megalithic monument in Morocco and is in fact the largest stone ellipse in the world. Mzora and the Egyptian Nabta Playa site are claimed to have used the same construction methods that Alexander Thom has shown to have been used by the British megalith builders.*A recent article by Sarah P. Young claims that “The circle is constructed using a Pythagorean right angled triangle with the ratios 12, 35, 37 and this is the same method used by 30 megalithic stone circles in Britain alone. Other similarities in construction and proportions exist such as the use of the so called ‘megalithic yard – a unit of measurement which seems to have been universally employed across Europe – and evidently even further afield” (g)*



Although no formal claim has been made for any connection with Atlantis, the supporters of the idea that the megalith builders were Atlanteans  see the complexity of the Mzora site as further justification for their opinion. A July 2018 paper(f) links the ancient Berbers with Mzora and as the Berbers occupied territory described by Plato as Atlantean (Timaeus 25a-b & Critias 114c), Mzora may also be legitimately described as Atlantean.

James Mavor, better known for his research at Santorini, surveyed the Mzora site in the 1970’s. Bob Quinn visited the site in 1982 and was struck by its similarity with Newgrange. Robert Temple discusses the site at length in his Egyptian Dawn[736]. Dale Drinnon has an illustrated blog on the subject(c).

John E. Palmer visited and surveyed the site in 1978 and subsequently wrote an article for Kadath magazine, unfortunately in French only. He reported that extensive damage was done to the site by ‘archaeologist’ César Luis de Montalban with excavations in 1935-6(d) and that many of the stones have been broken by ignorant Islamic extremists.

In 2011, Graham Salisbury gave coordinates for the site(b) and offers a history of Mzora in a longer article(e).

There is also a French site, which has a number of images of the Mzora site(a).

Vega, Manuel

Manuel Vega (1967- ) was born in Spain and studied Chemistry there and later worked as a research scientist in America and Japan. He travelled widely in the Far East before returning to the United States where he spent five years training a Buddhist monk before resuming a more secular life.

In 2012 he published Sailors of Stonehenge[868] in which he reviews the principal megalithic sites of Western Europe, including some interesting speculation. For example he describes the English Avebury complex as a site of ‘monarchical renewal’ and proposes related ceremonies at Stonehenge.  Another of what I consider his more fanciful ideas is his suggestion that Ireland’s Boyne Valley, which includes Newgrange, was used as a ‘royal funerary complex’ for dead English kings! He maintains that the location of many of these sites was determined by the position of astronomical features in the night sky.

Vega ends the book with a chapter on Atlantis, which he locates in the Atlantic and identifies the Atlanteans as the Megalith Builders. By the end of the 4th millennium BC they designed a huge celestial mirror over the Atlantic territories, which served to regulate themselves politically and religiously (implementing Heavens on Earth). The largest and most unique constructions, such as those at Carnac, Avebury, Stonehenge and Newgrange, were royal monuments erected at key sites of this celestial mirror according to a megalithic technology designed to attain the rebirth of the sacrificed kings again as princes, keeping an unbroken royal lineage.”

*   Vega returned to the subject of the megalith builders in 2015 with the publication of Voyage Zero[1443].  However, in 2017 he became even more contentious in Madrid is Atlantis[1444], which as the title implies, claims that Atlantis was located in the vicinity of the author’s native city.*

I found it very hard to accept most of his claims.

Those interested in reading more of Vega’s ideas can read his blogs(a).


Schoch, Robert M.

Robert M. Schoch is a Yale scholar, geologist and palaeontologist. At the invitation of John Anthony West he agreed to inspect robert schochthe Sphinx and offer an opinion of the nature of the erosion to be seen on it. He found that the cause of this erosion was due to precipitation rather than windblown sand. As Egypt has had an arid climate for many thousands of years, Dr Schoch reached the conclusion that at least the front of the Sphinx had been carved between 7000 and 5000 BC, when the climate had been considerably wetter.

In the same book, Voices of the Rocks[454], he endorsed (p.123) the conclusions of Mary Settegast[545] who claimed that Plato’s Atlantis story was a reference to the Magdalenian culture that inhabited the coastal regions of the Western Mediterranean during the 9th millennium BC. Schoch devotes a chapter to the subject of Atlantis and interestingly lists (p.87) a number of sites to which the Greeks applied the apellation ‘Pillars of Heracles’ apart from the Strait of Gibraltar.

In his Voyages of the Pyramid Builders he reiterates his conviction “that Plato’s story is, at least in part, a fictionalized account of a great Mediterranean war at a time of intense climatic change between the tenth
and eight millennia BC.”  A highly critical review of Schoch’s Book can be read online(n).

This 1990 declaration regarding the Sphinx generated an international reputation for Schoch. Such a controversial conclusion was obviously greeted warmly by the supporters of the 9,000 year old date for Atlantis allegedly given by the Egyptian priests to Solon. This accidental intervention by Schoch in the debate regarding the dating of Atlantis has unfortunately done nothing to resolve the issue. Fierce debate continues regarding the date of the Sphinx. However, there appears to be a gradual acceptance of Schoch’s views by other professional geologists such as David Coxhill. Another geologist, Colin Reader, while not accepting all of Schoch’s conclusions, believes that the Sphinx predates King Khufu, the father of Khafre, who has been traditionally accepted as the builder of the Sphinx, with the monument bearing his image.

It appears that Schoch’s experiences regarding the Sphinx has whetted Schoch’s appetite for prehistory as he has now written a further book[455], again with R.A. McNally about the origins of the pyramid builders. Unfortunately, he includes a reference to Ireland’s Newgrange as a form of ‘pyramid building’, an idea I reject since it shares neither form nor function with the Egyptian pyramids. Dr.Greg Little has written a very critical review of this book.

Schoch and McNally have recently dared to enter into the highly charged debate regarding the dating of the Great Pyramid at Giza[456][457].

Schoch appears to be venturing further and further from his natural comfort zone of geology. In 2007 he wrote an article on Telepathy(d) and was later due to address the Electric Universe Conference  in Las Vegas in 2012(c) and deliver a paper entitled The Catastrophic Termination of the Last Ice Age. In it, he will claim that that around 10,000 BC the earth underwent ‘dramatic catastrophic changes’ as a result of ‘our unstable Sun erupting at the end of the last Ice Age, melting the extensive glaciers and triggering climate warming. The full paper should be an interesting read.

His retreat from conventional science may be now complete as he delves into the strange world of lycanthropy (the study of werewolves)(o).

Schoch’s work is now promoted through his own website(b), which includes a wide range of articles. On it both he and his associate, Colette Dowell, have been very critical of the Bosnian pyramid claims of Semir Osmanagic following a visit there in 2006. However, in what appears to be an article(l) written in 2011 or 2012, Osmanagic responds with a scathing criticism of Schoch’s work.

Schoch has now turned his attention to the emergence and demise of very early civilisations, before that of dynastic Egypt or Sumeria. When he combined his early date for the Sphinx with other discoveries such as that of Nabta Playa and Göbekli Tepe and Gunung Padang(m), he concluded that the origins of civilisation go back much further than generally accepted. He then looked at the bigger and perhaps more important question of the cause of their collapse. In a 2009 special edition (N0.8) of New Dawn magazine he speculated on the possibility that the ending of such early civilisations was caused by the earth’s encounter with one or more asteroids or comets.

In his book(f), Forgotten Civilization[867],  Schoch claims that coronal mass ejections from the sun around 9700 BC devastated our planet with electrical discharges, the triggering of seismic and volcanic activity as well as ending the Ice Age with its consequent floods. All this ‘eradicated the civilisation of the time and set humanity back thousands of years, only to re-emerge around 3500 BC with scattered memories and nascent abilities.’ In an article written(g) in March 2012, Schoch wrote about the ‘Carrington Event’ of 1859 which resulted from a massive solar event that year.

*Schoch’s paper had the somewhat disturbing title of ‘Death Star’ and perhaps even more unsettling was the revelation in March 2019 that evidence of at least three major solar ‘proton attacks’ over the past 3,000 years. The suggestion being that these episodes are to be expected with some degree of regularity, which may create ever increasing disruption as our dependency on electricity expands. The recent report(q) indicates that the most powerful event identified so far, took place around 610 BC. Without power grids to damage at the time, we are unaware of what effect it had on the peoples of that time and I would hope that a review of the literature of that era might reveal some corroboration.*

A video clip is from his recent Las Vegas lecture is now available on YouTube(h). His talk is based on an article(i) in the July-August edition of New Dawn magazine, which is now available online and will play a large part in his Forgotten Civilization. He highlights some fascinating similarities between the Rongorongo script of Easter Island, the Nasca petroglyphs and the plasma figures of Dr. Anthony L. Peratt together with their possible association with the ending of the last Ice Age.

For me, the most disturbing aspect of Schoch’s book is his apocalyptic vision of global catastrophes that he anticipates  may turn the few survivors back into troglodytes!

However, Jason Colavito has reviewed Schoch’s claims relating to both the Rongorongo script(j) and Göbekli Tepe(k) and has found his ideas wanting. Colavito found further ammunition in the forthcoming book, Origins of the Sphinx[1374] which Schoch co-authored with Robert Bauval, describing it as ‘a virtual rewriting of’ Keeper of Genesis(p).

Quinn, Bob (t)

Bob Quinn (1935 – ) is an Irish filmmaker who was born in Dublin but now lives in Connemara in the west of Ireland. quinnbobAlthough he does not concern himself with demonstrating the reality of Plato’s Atlantis, he published a book[534] based on his four TV documentaries(a), which outline a wide range of ancient cultural connections between Ireland and North Africa, as well as other regions. The book and DVDs are a valuable source for those that see Atlantis as an echo of a prehistoric cultural ‘empire’ stretching along the North African coast and up the western seaboard of Europe. This would broadly coincide with those regions that are richest in megalithic remains.

Quinn visited the enormous stone circle at Mzora in Morocco and was struck by its similarity to Newgrange in Ireland(b).


Edo Nyland credits Quinn’s book as having provided some of the inspiration for his own Odysseus and the Sea Peoples[394].

Commencing Sept 27th 2011, the Irish TV channel TG4 broadcast a series of his documentaries every Tuesday, each one introduced by Quinn himself.

Quinn’s Atlantean documentary is available on YouTube(c).

Erlingsson, Dr. Ulf

Dr. Ulf Erlingsson is a Swedish geographer, geomorphologist and an expert in underwater mapping. In order to explain several puzzles regarding the Ice Age he developed The Captured Ice Shelf Hypothesis. He was the chairman of the Geographic Society of erlingssonUppsala, Sweden and 1991 he received the Linnaeus Prize from the Royal Society of Sciences in Uppsala.

Erlingsson is currently the American representative of AB Hydro consult(a), a spin-off from Uppsala University, Department of Physical Geography.

During the 1990’s while studying the geography of the Baltic region, Erlingsson obtained a set of Soviet maps, which greatly assisted the building of the database he was engaged in. However, these maps, which had been bought openly in Riga, outlined plans for a Russian invasion of Sweden in the event of a war in Europe with NATO(b).

Since moving to Florida, Erlingsson has been very involved politically with the ‘Progressive’ wing of the Democratic Party.

Erlingsson  recently identified the empire of Atlantis with the megalithic cultures of Western Europe and North Africa and suggested its capital may have been located in Ireland. His book[319] is interesting and contains a number of original ideas. However, as an Irishman, I am not convinced that our remarkable monuments in the Boyne Valley are the remains of or related to Atlantis. I will discuss this further in my review of his book. Erlingsson sees Atlantis everywhere, for example, in a carving on a stone basin in the Knowth passage tomb close to Newgrange. He has also suggested that the Irish authorities have deliberately made Newgrange inaccessible. This is total nonsense. As a regular visitor to the site over the years, I have witnessed nothing but every effort being made to maximise the throughput of visitors into the very confined space within our most famous national monument. The carved basin (see image) discovered near Newgrange, is perceived by Erlingsson as a replica of Plato’s Knowth stone basincircular city of Atlantis while I can see an early version of a Babylonian winged disk. In 2005, probably as a promotional ploy, he issued a challenge for an open debate on his theory.

Frank Joseph has related speculative ideas claiming that “the early date for New Grange, its circular construction, sophisticated solar orientation and mythic tradition all point to Atlantean origins.”[0636.70]

Erlingsson has more recently suggested that the ‘sunken’ island referred to by Plato was probably located in the vicinity of the southern end of the North Sea. He proposes that around 6100 BC a tsunami generated by a massive storegga off Norway reduced the then low-lying Dogger Bank to the impassable muddy shoals recorded by Plato!

Dr. Patrick Wallace, the Director of the National Museum of Ireland, declared that he was unaware of any archaeological evidence to support Erlingsson’s claims.

*Nevertheless, Erlingsson has produced some some interesting material on the bursting of glacial lakes or what are known in Iceland as jökulhlaups and their possible effect on the ending of the last Ice Age(c).





Concentric Rings

The Concentric Rings or other architectural features extracted by artists from Plato’s description of the capital of Atlantis have concentric circlescontinually fascinated students of the story and many have attempted to link them with similar ancient features found elsewhere in the world as evidence of a widespread culture. Stonehenge, Old Owstrey, Carthage and Syracuse have all been suggested, but such comparisons have never been convincing. Diaz-Montexano has recently published(a) an image of a fragment of pottery found near Seville in Spain that shows concentric circles and insists that it is a symbol of Atlantis. Ulf Erlingsson has made a similar claim regarding some concentric circles carved on a stone basin found at Newgrange in Ireland.

Less well-known are the concentric stone circles that are to be found on the island of Lampedusa in the Strait of Sicily(b).

In 1969 two commercial pilots, Robert Brush and Trigg Adams, photographed a series of large concentric circles in about three feet of water off the coast of Andros in the Bahamas. Estimates of the diameter of the circles range from 100 to 1,000 feet. Apparently, these rings are now covered by sand. It is hard to understand how such a feature in such very shallow water cannot be physically located and inspected. Richard Wingate in his book[0059] estimated the diameter at 1,000 yards. However, the rings described by Wingate were apparently on land, among Andros’ many swamps.

Two papers presented to the 2005 Atlantis Conference on Melos describe how an asteroid impact could produce similar concentric rings, which if located close to a coast could be converted easily to a series of canals for seagoing vessels. The authors, Filippos Tsikalas, V.V. Shuvavlov and Stavros Papamarinopoulos gave examples of such multi-ringed concentric morphology resulting from asteroid impacts. Not only does their suggestion provide a rational explanation for the shape of the canals but would also explain the apparent over-engineering of those waterways.

At the same conference the late Ulf Richter presented his idea, which also suggests that the concentric rings around the centre of the Atlantis capital had a natural origin. Richter has proposed that the Atlantis rings were the result of the erosion of an elevated salt dome that had exposed alternating rings of hard and soft rock that could be adapted to provide the waterways described by Plato.

Georgeos Diaz-Montexano has suggested that the ancient city under modern Jaen in Andalusia, Spain had a concentric layout similar to Plato’s description of Atlantis. In August 2016 archaeologists from the University of Tübingen revealed the discovery(i) of a Copper Age, Bell Beaker People site 50km east of Valencina near Seville, where the complex included a series of concentric earthwork circles.

Gilgal refai'm

*A very impressive example of man-made concentric stone circles, know in Arabic as Rujm el-Hiri and in Hebrew as Gilgal Refaim(a), is to be found on the Golan Heights. It consists of four concentric walls with an outer diameter of 160metres. It has been dated to 3000-2700 BC and reputed to have been built by giants! Mercifully, nobody, has claimed any connection with Atlantis.That is until 2018, when Ryan Pitterson made just such a claim in his book, Judgement of the Nephilim[1620].*

Jim Allen in his latest book, Atlantis and the Persian Empire[877], devotes a well illustrated chapter to a discussion of a number of ‘circular cities’ that existed in ancient Persia and which some commentators claim were the inspiration for Plato’s description of the city of Atlantis. These include the old city of Firuzabad which was divided into 20 sectors by radial spokes as well as Ecbatana and Susa, both noted by Herodotus to have had concentric walls. Understandably, Allen, who promotes the idea of Atlantis in the Andes, has pointed out that many sites on the Altiplano have hilltops surrounded by concentric walls. However, as he seems to realise that to definitively link any of these locations with Plato’s Atlantis a large dollop of speculation was required.

Rodney Castleden compared the layout of Syracuse in Sicily with Plato’s Atlantis noting that the main city “had seen a revolution in its defensive works, with the building of unparalleled lengths of circuit walls punctuated by numerous bastions and towers, displaying the city-state’s power and wealth. The three major districts of the city, Ortygia, Achradina and Tycha, were surrounded by three separate circuit walls; Ortygia itself had three concentric walls, a double wall around the edge and an inner citadel”.[225.179]

Dale Drinnon has an interesting article(d) on the ‘rondels’ of the central Danubian region, which number about 200. Some of these Neolithic features have a lot in common with Plato’s description of the port city of Atlantis. The ubiquity of circular archaeological structures at that time is now quite clear, but they do not demonstrate any relationship with Atlantis.

The late Marcello Cosci based his Atlantis location on his interpretation aerial images of circular features on Sherbro Island, but as far as I can ascertain this idea has gained little traction.

One of the most remarkable natural examples of concentric features is to be found in modern Mauritania and known as the Richat Structure or Guelb er Richat. It is such a striking example that it is not surprising that some researchers have tried to link it with Atlantis. Robert deMelo and Jose D.C. Hernandez(o) are two advocates along with George S. Alexander & Natalis Rosen who were struck by the similarity of the Richat feature with Plato’s description and decided to investigate on the ground. Instability in the region prevented this until late 2008 when they visited the site, gathering material for a movie. The film was then finalised and published on their then newly established website in 2010(l), where the one hour video in support of their thesis can be freely downloaded(m).

In 2008, George Sarantitis put forward the idea that the Richat Structure was the location of Atlantis, supporting his contention with an intensive reappraisal of the translation of Plato’s text(n). He developed this further in his Greek language 2010 book, The Apocalypse of a Myth[1470] with an English translation currently in preparation.

However, Ulf Richter has pointed out that Richat is too wide (35 km), too elevated (400metres) and too far from the sea (500 km) to be seriously considered as the location of Atlantis.

A dissertation by Oliver D.Smith has suggested(e) the ancient site of Sesklo in Greece as the location of Atlantis, citing its circularity as an important reason for the identification. However, there are no concentric walls, the site is too small and most importantly, it’s not submerged.*Smith later decided that the Atlantis story was a fabrication!(p)*

Brad Yoon has claimed that concentric circles are proof of the existence of Atlantis, an idea totally rejected by Jason Colavito(j).

In March 2015, the UK’s MailOnline published a generously illustrated article(g) concerning a number of sites with unexplained concentric circles in China’s Gobi Desert. The article also notes some Gobi Desertsuperficial similarities with Stonehenge. I will not be surprised if a member of lunatic fringe concocts an Atlantis theory based on these images. (see right)

This obsession with concentricity has now extended to the interpretation of ancient Scandinavian armoury in particular items such as the Herzsprung Shield(c).

In 2011 Shoji Yoshinori offered the suggestion that Stonehenge was a 1/24th scale model of Atlantis(f). He includes a fascinating image in the pdf.

For my part, I wish to question Plato’s description of the layout of Atlantis’ capital city with its vast and perfectly engineered concentric alternating bands of land and sea. This is highly improbable as the layout of cities is invariably determined by the natural topography of the land available to it(h). Plato is describing a city designed by and for a god and his wife and as such his audience would expect it to be perfect and Plato did not let them down. I am therefore suggesting that those passages have been concocted within the parameters of ‘artistic licence’ and should be treated as part of the mythological strand in the narrative, in the same way that we view the ‘reality’ of Clieto’s five sets of male twins or even the physical existence of Poseidon himself.

Furthermore, Plato was a follower of Pythagoras, who taught that nothing exists without a centre, around which it revolves(k). A concept which may have inspired him to include it in his description of Poseidon’s Atlantis.

Atlantis from a Geographer’s Perspective

Atlantis from a Geographer’s Perspective [319] by Dr. Ulf Erlingsson, a Swedish geographer and geomorphologist, endeavours to identify Ireland as the original Atlantis described by Plato. As an Irishman, I would be delighted to support this view, if the evidence was strong enough. Unfortunately, I cannot see Erlingsson’s book advancing the case for an Irish Atlantis. I am willing to accept that the megalithic cultures of Western Europe and North Africa were probably part of a loose confederation of societies that led to a later tale of a mighty empire, as its existence was relayed through the myths of succeeding civilisations. However, to claim that Topography_IrelandIreland was the centre of this civilisation is rather fanciful and unsubstantiated by anything other than the fertile imagination of Dr. Erlingsson.

Erlingsson refers to Henry O’Brien’s book, The Round Towers of Ireland[0124] as a sort of precursor of his own. In fact, O’Brien’s book was an attempt to link the Round Towers of Ireland with a pre-Christian period. O’Brien never referred to Plato or Atlantis at all. Now after more than a hundred and fifty years, no evidence to support O’Brien’s claim has been forthcoming. There is a consensus that the round towers date from the early part of the first millennium AD, but it must be admitted that with regard to their purpose, some mystery still exists.

The most glaring flaw in Erlingsson’s theory is his arbitrary use of the diagonal dimensions of Ireland in order to shoehorn it into Plato’s dimensions. Using the island’s latitudinal and longtitudinal dimensions, a much smaller figure would have resulted. However, his application of Plato’s 3,000 x 2,000 stadia (550 x 370 km) to the entire island, is dishonest as Plato’s figures only refer to the plain of Atlantis, whereas the Central Plain of Ireland would only occupy a fraction of that area.

Some of my other reasons for dismissing Dr. Erlingsson’s theory are:

  1. Ireland is too far north to have produced two crops annually and*was mainly covered in ice during the last Ice Age.*Furthermore;
  2. Ireland did not disappear beneath the sea
  3. Ireland has always been somewhat short of elephants
  4. Ireland does not have hot springs
  5. There is no evidence of any harbour in the immediate vicinity of Tara or Newgrange.
  6. Conventional archaeology indicates that Ireland did not have dressed stone structures until around 5th Century AD.

Obviously, Erlingsson must realise that he is on a loser with Ireland, as he now seems to have shifted his attention more fully to the Dogger Bank in the North Sea.

My final gripe with the book, or should I say booklet, as it contains just a hundred pages, is that it lacks an index, an irritating omission that a number of authors reviewed here have also been guilty of.

*On 19th August 2004, the respected The Irish Times newspaper, reported(c) that Erlingsson had appeared to backtrack on some of his initial claims when he said that The existence of Atlantis has never been proven” and that “the purpose of his book was to test Plato’s claim that he based the utopia on a real, historic place.”*


It’s over ten years since I read Erlingsson’s book and have only recently re-read it because the author wrote to me complaining that I had included inaccuracies in my original comments on his book. Having perused the first chapter again, I quickly realised that any shortcomings on my part were greatly exceeded by those of Erlingsson’s.

Firstly, he claims that Atlantis was Ireland, but the island which sank, referred to by Plato, was in the North Sea, part of Doggerland. He claims that the story of a sunken island was a tale from Atlantis, not about Atlantis! He attempts to explain this away by simply claiming that Solon/Plato made a mistake! It is far more likely that Erlingsson is making a mistake.

He then uses Doggerland to explain away the elephants that Plato said inhabited Atlantis, claiming that the remains of mammoths were reclaimed from the North Sea. However, he fails to record that the mammoths in question were dated at 40,000 BC(b), tens of thousands of years before Atlantis.

My second complaint is that he initially matches the dimensions of the entire island of Ireland with those of the plain of Atlantis given by Plato, namely 3000 x 2000 stadia. I have already pointed out that if you remove the mountains from the Ireland, the remaining plains of our island, if combined, might amount to a third of that of the plain of Atlantis(a). In order to shoehorn Ireland into his hypothesis he abitrarily chose to use a value of 166m to the stade, instead of the more generally accepted 185m. On top of that, as already noted, he measured Ireland diagonally rather than north-south and east-west.

Furthermore, speaking of mountains, the highest Irish peak is only 1,038m high. On the other hand, Plato describes the mountains of Atlantis being renowned for their number, size and beauty, which apart from beauty cannot be applied to the Irish mountain ranges. I would expect better from a geoghrapher.

The first chapter contains other errors, including the idea that the ancient Greeks knew of America. In fact they only knew of three continents, Europe, Asia and Libya (Africa). Herodotus, who flourished after Solon and before Plato, was quite clear that there were only three known to the Greeks. [Histories 4.42].

There are more speculative claims in this first chapter, but, at this point I could take no more and gave up, unwilling to waste any more time on this nonsense. Erlingsson claims that his hypothesis matches Plato’s Atlantis story with a probability of 99.98%. Hilarious.




Ó Síocháin, P. A. (L)

Padraig_A__O_SiochainPadraig A. Ó Síocháin (1905-1995) was an Irish barrister and author of a number of books on law and history. In addition, he has written about prehistoric Ireland[498] including a number of chapters linking Ireland or more particularly the story of the legendary Hi-Brasil with the Atlanteans.

He loved the Aran Islands where he perfected his fluency with the Irish language and about which he devoted another of his books[499].

He was firmly convinced that these islands had once been connected to the mainland and offers evidence in support of this view.

His sober account of Ireland’s possible links with Atlantis is, in my view, a valuable addition to Atlantean literature. It contains some fascinating details such as the designs incorporated into the famous Aran knitwear being a possible reflection of motifs found incised on the megaliths at Newgrange and elsewhere. On a less serious note he also recounts that the Celts introduced soap to the Romans and Greeks!

Megalith Builders

The Megalith Builders, who date mainly from the Neolithic Period, are frequently identified with Plato’s Atlanteans. Their remarkable structures were built between the middles of the fifth and second millennia B.C., a period that is compatible with final days of Atlantis according to Plato. Proponents of the idea of a megalithic building Atlantis see the location and extent of the megalithic structures as being in agreement with Plato’s description, particularly his reference to Atlantean influence extending as far as Tyrrhenia and Egypt.

However, there are many features in Plato’s narrative that do not conform to our current knowledge of the megalith builders. There is no evidence that they had writing, irrigation technology or the navigational skills to mount an attack on Egypt/Athens or any other characteristics ascribed to the Atlanteans by him.

On the other hand, if these attributes are just literary flesh applied to a skeleton of historical truth the possibility of a link between the Atlanteans and the megalith builders still remains.

Atlantis enthusiasts are quite happy to associate the megalith builders with Atlantis, as it provides something tangible to enhance the credibility of Plato’s narrative pointing to sites such as Stonehenge or the Maltese Temples. British researcher Robert John Langdon has gone further and proposed that the megalith builders originally came from Africa and settled in Doggerland at the end of the Ice Age, where they established Atlantis[919]. When Doggerland was submerged they migrated to what is now mainland Britain, where they built Stonehenge as a memorial to Atlantis.

Manuel Vega, who places Atlantis in the Atlantic has some novel ideas regarding Stonehenge as well as Ireland’s Newgrange [0868].

Paul Dunbavin in his Atlantis of the West[0099] promotes the idea of a megalithic Atlantis centred off the coast of Wales.

While not a new idea, a megalithic connection with Atlantis has recently been given further attention by the French writer Sylvain Tristan who was inspired by Jean Deruelle and Alan Butler. Alfred deGrazia also joined this club as well as the German author Helmut Tributsch who has added his support to the idea of a megalithic Atlantis, specifically locating its capital on the island of Gavrinis in Brittany. A similar claim has been made by Hank Harrison who also believes that the Morbihan region was an important Atlantean centre if not the location of its capital. Further support for a megalithic Atlantis has been given by Walter Schilling who places Plato’s city in the Bay of Cadiz. Robert Temple has recently offered grudging support for the concept of Atlantean megalith builders.

As far as I am aware classical writers make no obvious reference to the megalith builders, nor has this omission been commented on by modern writers. However, the numerous indirect references to Atlantis by the same ancient writers are deemed inadequate. This seems rather inconsistent to me.

It appears to me that other questions that have not been definitively answered relate to the identity of the megalith builders, why they stopped building and what happened to them. Another thought is that if the megalith builders lived at the same time as the Atlanteans, is it not strange that both disappeared around the same time, or did they?

Parallel with the megaliths of the eastern Atlantic seaboard are the megaliths of North America. Who built them and when? Are they evidence of very early pre-Columbian voyagers from Europe?(b)

An interesting article combining all the strange aspects of megalith building can be read online(c)  which certainly offers food for thought. A paper(d) published in September 2013 gives a good overview of megalithic studies during the past few decades. Walter Haug’s well illustrated website(k) offers a range of previously ignored megalithic sites in Germany.

Much nonsense has been written about the megalith builders, particularly on the Internet, where you find daft ideas such as attributing their construction to aliens(a). The suggestion that extraterrestrials had the technology to travel in space but when they land on earth they have to build observatories with stone is just silly.

A valuable website dealing with the global spread of megalithic monuments, is The Megalithic Portal established by Andy Burnham(g), which has regular updates. Other useful sites are Stone Pages(h) and Megalithic Ireland(i). Another site worth a look is from Sjur C. Papazian(l). There is also a site(j) dealing specifically with the dolments of Corsica and Sardinia.

In the Middle East dolmens stretch in a line from the Caucasus(s)(p) to the Yemen with a concentration in Jordan(m), a fact which prompted a former Dutch ambassador to Jordan, Gajus Scheltema, to write Megalithic Jordan[1206]. Jordan is also home to an ancient mysterious 150 km wall, which was 1-1.5 metres high.(u)

Dolmens are also found in more distant lands such as India(r), Korea(n)(v) and Japan(o). It is difficult to look at the worldwide distribution of dolmens and not consider the possibility of some form of global cultural diffusion! Rarely discussed are the widely dispersed megalithic remains found throughout the Pacific islands(q).

There is a well-illustrated website offering an overview of the megalithic culture of Western Europe and the Mediterranean(t).

In February 2019 the Smithsonian Magazine had a report telling us that Bettina Schulz Paulsson, an archaeologist at the University of Gothenburg, reexamined some 2,410 radiocarbon dating results that have been assigned to Europe’s megaliths and put them through a Bayesian statistical analysis. Based on the picture the data present, Schulz Paulsson believes that the megaliths were first constructed by dwellers of northwest France during the second half of the fifth millennium BC.” (w) Mike Parker Pearson, the leading Stonehenge expert, has endorsed this idea of a French origin for megalith building(x).

*The interesting claims of Schulz Paulsson, who place the origins of megalithic construction to Brittany in the fifth millennium BC, may be challenged by a little-known counterclaim that tombs in the Ox Mountains in the west of Ireland have been dated to the seventh millennium BC(y). However, my personal view is that it would be more likely that the practice of megalith building would have spread from the east rather than from Ireland westward!*

A rational explanation for the construction of cyclopean masonry has been offered by Professor of Architecture Jean-Pierre Protzen and demonstrated on a YouTube clip(f).
