    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.Read More »

Megalithic Yard, The

The Megalithic Yard is a controversial unit of measurement originally proposed by Alex Thom following a study of hundreds of megalithic sites in Britain and Brittany. Very many attempts have been made to verify his conclusions, but to no avail. Wikipedia(d) offers an interesting overview of the wide-ranging theories that the controversy has thrown up.

Humans have used their body parts as measuring tools right up to the present day, e.g. foot, finger or hand, so it was not surprising that the human pace provided a unit of measurement which has been suggested by many as the original megalithic ‘yard’.

Not unexpectedly, some researchers, such as Ulf Erlingsson(a), Sylvain Tristan(b) and Jim Allen(c) have endeavoured to link the megalithic yard with their interpretation of Plato’s Atlantis, sometimes with convoluted associations with ancient Egyptian and/or Sumerian metrics!

There is also an ancient unit of measurement known as the ‘long foot’ of 12.7 inches (32.2 cm). In early 2019, archaeologists from the University of Manchester and University College London concluded, after a study of three small carved chalk ‘drums’, that they “could be ancient replicas of measuring devices used for laying out prehistoric monuments like Stonehenge.” They found that “a string wound 10 times around the smallest of the drums would give a measure of exactly 10 long feet — a length used to lay out several ancient henge monuments(e).







Brittany in northwestern France is sometimes referred to as Little or Lesser Britain. It is one of the most exciting regions of Megalithic Europe. The stone rows of Carnac are unequalled, Le Grand Menhir Brisé was once the largest standing stone in Europe, while BrittanyMorbihan contains a huge number of dolmens and standing stones.2019 saw a report 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.” (b) Mike Parker Pearson, Stonehenge’s leading, authority, has endorsed this idea of a French origin for megalith building(c). 

The earliest suggestion that Atlantis may have been the connected with the Armorican peninsula came from François Gidon in the 1930’s when he proposed that Atlantis had been situated on an exposed Celtic Shelf stretching from Brittany to Ireland. Unfortunately, he dates the submergence of this land to between 3000 and 1200 BC, which was millennia after that part of the Celtic Shelf had been inundated by the Flandrian Transgression.

Jean Markle was convinced that the Carnac stone were connected with Atlantis. Recently, Sylvain Tristan followed the work of Jean Deruelle in supporting a megalithic Atlantis. Further support has come from Alfred deGrazia and Helmut Tributsch who saw Megalithic Europe as Atlantis with the island of Gavrinis in Brittany as its capital.

The American researcher, Hank Harrison, considers the Morbihan départment as a significant Atlantean location if not the home of its capital.

Reinoud deJonge proposes even greater significance for the Brittany megaliths with his claim that they record the Flood of Noah in 2344 BC(a).

Doggerland is a term applied to a shallow region (Fig.1) of the North Sea between Denmark and the North of England that covers area of around 10,000 sq. miles. The appellation was coined by Professor Bryony Coles in 1998. However, the name has been applied recently(f) to nearly the totality of the Celtic Shelf (Fig.2). Ulf Erlingsson who had promoted his theory(b) that Atlantis hDoggerland2ad been located in Ireland (with 98.9% confidence!) has explained that Egyptian story of Atlantis is the result of an account of megalithic Ireland conflated with a report of the inundation of Doggerland in 6200 BC resulting from a Norwegian storegga. In turn, this flooding may have been the inspiration behind the ‘impassable shoals’ described by Plato following the submergence of Atlantis.

However, it was Rachael Carson who was probably the first to suggest the Dogger Bank as the home of Atlantis in her 1951 book, The Sea Around Us[1267].  Later a Scandinavian writer, Nils Olof Bergquist, in his 1971 book, Ymdogat-Atlantis[785]. who appeared next to support this idea.   

Other writers such as Jean Deruelle(a), Sylvain Tristan(c) and Guy Gervis(d) have also linked the Dogger Bank with Atlantis. Gervis has written two related papers(k)(l) on the subject. The earliest suggestion of such a  connection was briefly supported by Robert Graves[342.39-3]. Rob Waugh, a British journalist, has offered an illustrated article(g) with the provocative title of Britain’s Atlantis found at the Bottom of the North Sea, in which he touches on some of the discoveries made on Doggerland.

Some have combined Doggerland with exposed land further north, now known as the Viking-Bergen Banks, as constituting the territory of Atlantis(x).

In 2009 a book[662] was published with the subtitle of The Rediscovery of Doggerland, based on the research of a team led by Professor Vincent Gaffney of the University of Birmingham. In July 2012 the UK’s Daily Mail published(h) an extensive article on Doggerland.

The flooding of the Dogger Bank has been attributed to a 6200 BC event apparently caused by either an outpouring of meltwater from Lake Agassiz in North America or a huge tsunami generated by a Norwegian storegga(e). This  event was covered in an extensive article in the November, 2012 edition of the BBC Focus magazine. The same article has a sidebar on Atlantis which suggests that there is “perhaps just one archaeological theory that has any serious claim on the myth.” Then, not for the first time, the BBC offered tacit support for the Minoan Hypothesis in spite of the fact that, at least ostensibly, it does not match Plato’s description of Atlantis in terms of either time, size or location and offers no rationale for its stance.

In December 2020, a degree of revisionism was offered in a New Scientist article, which suggested that storegga tsunami may have been less than previously thought. Furthermore, it proposes that parts of what is now the submerged Dogger Bank was not completely flooded by the tsunami, but that parts continued as dry land, perhaps for centuries!(y)

It has been estimated that over a period of a couple of hundred years the English Channel was also created in a comparable manner(n).

The December 2012 edition of National Geographic magazine has also published an informative article on Doggerland and the ongoing work by archaeologists in the region. It considers the Storegga or the Lake Agassiz meltwater to be the cause of Doggerland’s final inundation. For me it was interesting that a map in the article showed a small area around where I live as the last glaciated region of Ireland.

Alfred de Grazia’s online Q-Mag also published an overview of the Doggerland story in 2012(j) that was originally taken from the German magazine Der Spiegel. The same site has another paper(r) by Jean Deruelle in which he also argues that Doggerland was the location of the Great Plain of Atlantis that stretched from the east of the Dogger Bank and extended as far as what is now Denmark. Plato described the plain as being surrounded by a huge ditch. Then Deruelle, with a flash of ingenuity claims that it was not a ditch but instead was a dyke, designed to hold back the slowing advancing waters of the North Sea that were being fed by deglaciation. He endeavoured to reinforce this claim with the proposal that the Greek word for ditch, ‘taphros’ can also be used for dyke. This interpretation seems possible according to W.K. Pritchett, the distinguished historian [1622.52.5].

Robert John Langdon has proposed that megalith builders from Africa came to Doggerland as the Ice Age ended and when Doggerland submerged they migrated to what is now mainland Britain, eventually constructing Stonehenge(i).

A 2014 ‘Drowned Landscapes’ exhibition(m) organised by Dr Richard Bates of the Department of Earth Sciences at St Andrews University, reveals in greater detail the flora and fauna, as well as the lives of its inhabitants, of this submerged world. Much of the information was gleaned from data provided by oil and gas companies, combined with artifacts recovered from the seafloor.

Comparable discoveries have been made submerged deep under the waters of Hanö Bay near the coast of Havang, Sweden and dated to about 7000 BC(v).

In 2015 it was announced that €2.5 million funding from the European Union has enabled a number archaeologists from Britain’s top universities to team up for what will be the most intensive study of Doggerland so far(o)(q). Joined by experts from the University of Ghent and assisted by the Belgian Navy they located the first identifiable submerged settlements on the floor of the North Sea. Until now (2019) the only evidence of human habitation in the region were occasional artefacts caught up in fishermen’s nets.

In 2016, it was revealed(p) that the ancient footprints of both adults and children had been discovered off the coast of Northumberland, formerly a part of Doggerland. Their feet had apparently been shod.

On Sunday, January 13th 2019. the UK’s Sunday Express delighted its readers with two Atlantis stories(t)(u) . First, the online edition of the paper had a story by one of its reporters, with an ‘Atlantis Discovered’ headline claiming that the remains of an ancient 8,000-year-old city, home to ‘tens of thousands’ of people, had been discovered in the North Sea, in a huge region sometimes referred to as Doggerland. The reporter cites Dr.Richard Bates in support of this account. Unfortunately, the 2012 comments by Dr. Bates never mentioned ‘a city’, but a vast area occupied by ‘tens of thousands’ of people, presumably early farmers(s) . Then the same edition of the same paper by the same ‘reporter’ with another ‘Atlantis Found?’ headline, offered a video clip of the Maltese island of Filfla, while the commentator told us that Plato had said that a devastating earthquake had destroyed Atlantis it was finished off by an eruption. This is factually incorrect as Plato never mentioned an eruption. These two accounts are a sad reflection on the quality of media reporting today.

North Sea

The North Sea has been advocated by a variety of writers as the original site of Atlantis. Jürgen Spanuth specified his native Heligoland as its location in his well-researched work, Atlantis of the North[015]. >However, Spanuth was not the first to make this suggestion as Heinrich Pudor, had advocated Helgoland as Atlantis in the 1930’s [1693][1694], but was unreferenced by Spanuth.<

Robert Scrutton drew heavily on the contents of the controversial Oera Linda Book to support his view of an Atlantis or Atlantean colony in the Frisian Islands of the North Sea[117][118].

Georg Lohle in his book[446] on world history identifies a location between England and Denmark that was inundated about 2000 BC. He also makes extensive use of the Oera Linda Book. His German language website(a) has a wide range of photos and diagrams. Lohle daringly resurrects the old idea of the Earth being hollow and then combines it with another controversial concept, namely that it is still expanding(b).

In the middle of the 20th century we find Robert Graves and Rachel Carson were probably the first to suggest the Dogger Bank as the location of Atlantis. More recently Jean Deruelle(e), Sylvain Tristan(c) and Guy Gervis(d) have all opted for a location near the Dogger Bank, now more popularly known as Doggerland.

The most recent challenger for the Atlantis title is located in the vicinity of Rockall, an uninhabited islet north west of Ireland.

Identity of the Atlanteans (m)

The Identity of the Atlanteans has produced a range of speculative suggestions nearly as extensive as that of the proposed locations for Plato’s lost island. However, it is highly probable that we already know who the Atlanteans were, but under a different name.

The list below includes some of the more popular suggestions and as such is not necessarily exhaustive. While researchers have proposed particular locations for Atlantis, not all have identified an archaeologically identified culture to go with their chosen location. The problem being that most of the places suggested have endured successive invasions over the millennia by different peoples.

It would seem therefore that the most fruitful approach to solving the problem of identifying the Atlanteans would be to first focus on trying to determine the date of the demise of Atlantis. This should reduce the number of possible candidates, making it easier to identify the Atlanteans.

A final point to consider, is that the historical Atlanteans were a military alliance, and as such may have included more than one or none of those listed here. The mythological Atlanteans, who included the five sets of male twins and their successors would be expected to share a common culture, wheras military coalitions are frequently more disparate.

Deruelle, Jean

Jean Deruelle (1915-2001) was a French mining engineer, who identified Northern Europe as the cradle of technological development, preceding the great civilisations of the Middle East. He contends that the advances of Northern Europe diffused to the southern nations of the Mediterranean. Deruelle identified Imhotep as an Atlantean immigrant to Egypt, where he contributed to the advances of its civilisation during the 3rd millennium BC and became its chief architect.

More specifically, he places Atlantis in the North Sea, on the Dogger Bank, which is a shoal around 100 km off the northeast coast of England. He has written at least two books[278][279] on the subject of Atlantis.

Deruelle identified the megalith builders of western Europe as Atlanteans, an idea adopted by Sylvain Tristan.

A number of maps illustrating his theory are available on a French forum(a).

Fortunately, an English translation of his theory is available on the de Grazia website(b).

*Deruelle imaginatively proposed that great plain of Atlantis lay to the east of the Dogger Bank, stretching as far as what is now Denmark. Plato described the plain being surrounded by a huge ditch. Then Deruelle, with a flash of ingenuity claimed that it was not a ditch but instead was a dyke, designed to hold back the slowing advancing waters of the North Sea that were being fed by deglaciation. He endeavoured to reinforce this claim with the proposal that the Greek word for ditch, ‘taphros’ can also be used for dyke. This interpretation seems possible according to W.K. Pritchett, the distinguished historian [1622.52.5].*



Mermet, Roger (L)

Roger Mermet is one of a number of French researchers, including Jean Deruelle, Sylvain Tristan, who have opted for a North Sea location for Atlantis, following the work of Jürgen Spanuth. Mermet has written one book on ancient civilisations[664]  with the tempting title of Le Passé Antérieur – Lascaux l’Atlantide et l’Ile de Paques (The Past Background – Lascaux, Atlantis and Easter Island).

Tristan, Sylvain

Sylvain Tristan is young French researcher who has adopted the theories of Jean Deruelle, who advocated the idea that the sylvain tristanAtlanteans were in fact the Megalith Builders of the Bronze Age who left us a legacy of remarkable structures from Scandinavia, along the Atlantic seaboard including the British Isles and on down into the Mediterranean as far as Malta. Tristan also subscribes to Deruelle’s contention that the capital of this civilisation had been located on the Dogger Bank in the North Sea, between England and Denmark.

A second major influence on Tristan’s thinking was the writings of Alan Butler, who among other matters, has argued[623] for the use of 366-degree geometry by the Megalith Builders. Butler wrote the Foreword to Tristan’s Les Lignes d’or, it can be read on Tristan’s English language website(b), while the French text of the book is available online(e).

Tristan returned to the subject of 366-degree geometry in his latest book, Numbers of the Gods[1399].

Tristan has expanded on the work of his mentors in two books[624][625] .

An interview with Tristan can be accessed on the Internet(a). Unfortunately, his non-fiction output have only been published in French so far, but in 2012 he published, The Divine Number, in English, as a Kindle book(c). This novel is based on a series of secrets associated with the 366 degree geometry of Butler’s research. He introduces the book in a short YouTube clip(d).

Tristan’s idea of a megalithic Atlantis has been heavily criticised by Alain Moreau(f).
