Hyperdiffusion with Atlantis at its centre was argued at great length by Ignatius Donnelly when he proposed Atlantis as the mother culture, located in the Atlantic. Through colonisation and migration, their civilisation was brought to the Americas and the Mediterranean, particularly Egypt. The idea received widespread support at the time and has persisted until today(a). A similar proposal was made by James Churchward in connection with his Pacific island of Mu.
>Angelo Mazzoldi expressed support for a form of regional hyperdiffusion that had his Italian Atlantis as the mother culture which seeded all the great civilisations of the eastern Mediterranean region.<
However, even earlier, in the seventeenth century, Olof Rudbeck “purported to prove that Sweden was Atlantis, the cradle of civilization, and Swedish the original language of Adam from which Latin and Hebrew had evolved.”(i)
Since Atlantis in the Atlantic is considered by many to be highly improbable and Mu only existed in Churchward’s imagination, a more likely explanation is that diverse ideas emerged independently in different locations, possibly around the same time. These developments then diffused through trade and migration in various directions, sometimes returning in an improved format. The result is that today we are finding that most ancient civilisations show evidence of cultural influences from more than one source.
>Lawrence Freeman is the American author of Beyond The Pillars: a search for Antediluvian civilizations(l) in which he reviews almost every civilisation and prehistoric mystery that you ever heard of. He refers to Atlantis throughout the book, but in rather sceptical tones, with the nearest to a conclusion being that – “Atlantis may well have never existed, but if it did exist, then it was likely only as part of a worldwide antediluvian civilization that is now coming to light.”<
Richard Cassaro and Jim Allen have both published online large collections of images(b)(c)(d) that clearly demonstrate widespread diffusion. This is particularly so in the case of South America where influences from both east and west are clearly evident. While it is regularly claimed that Egypt influenced South American civilisations it is obvious that Asian inspiration was equally, if not solely, at work. The existence of pyramids in both Egypt and Mesoamerica is put forward as evidence of contact between them. However, the problem is that the American pyramids were constructed hundreds if not thousands of years later than the Egyptian ones. However, in spite of this separation by time and distance, the Egyptians and the Aztecs also shared feathered-serpent deities(g)! What appears to be overlooked is the fact that the Chinese pyramids are more like Mesoamerican examples and are dated to the second half of the first millennium BC, again closer to the development of pyramids in Mesoamerica.
>Christian O’Brien contended that global cultural hyperdiffusion was centred in Southern Lebanon (the Garden of Eden) and was spread from there by ‘The Shining Ones’ leading to the establishment of some of the great civilisations of our ancient past!(m)<
An even more unusual hyperdiffusionist opinion was expressed by the Argentine palaeontologist, Florintino Ameghino (1854-1911), who thought that mankind originated in South America(h) and spread globally from there!
>In 2020, Anthony Woods  attempted to prove that Atlantis was Ireland and also the source of the mother culture for the entire world. As an Irishman, when reading this, I did not know whether to laugh or cry.<
>In March 2021, Hugh Newman published a paper drawing attention to the similarity of megalithic building techniques, using polygonal stones, found in America, Asia, Europe and Africa. He goes further, noting that “Peruvian relief carvings match those at Göbekli Tepe.” How much might be the result of coincidence or hyperdiffusion is a matter of opinion.(k)<
>Carl Feagans offers a paper that is highly critical of hyperdiffusion and its promoters, denouncing them as “willfully ignorant and grossly racist. Though they don’t say it directly, the message is still the same: “white people did it, not savages.”(j)<
A 1986 paper(f) by Ben Urish entitled Cultural Diffusion should be read in this connection.

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 the final days of Atlantis according to Plato. The building of megalithic structures in Western Europe appears to have ended just before the beginning of the Bronze Age – coincidence? Emmet Sweeney, however, contends that “the great Megalithic-building culture of Atlantic Europe and North Africa commenced around 1100 BC or perhaps a little earlier”! [700.208]
Proponents of the idea of a megalithic building in Atlantis see the location and extent of the megalithic structures as agreeing with Plato’s description, particularly his reference to Atlantis being ‘beyond the Pillars of Heracles’. However, the location of the ‘Pillars’ at the time of Solon’s visit to Egypt, is strongly disputed. In fact, the only territory unambiguously named by Plato as Atlantean was in southern Italy and North Africa along with several islands of which there are many in that region.
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 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 there is the possibility of a link between the Atlanteans and the megalith builders remaining.
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. When Doggerland was submerged they migrated to what is now mainland Britain, where they built Stonehenge as a memorial to Atlantis.
Megalith building in North Africa has been documented for over a century. The Hill of Graces by H.S. Cowper in 1897 concentrated on describing the megaliths in the region of Tripoli. The Mzora Stone Circle is a huge megalithic monument in Morocco and is considered to be the largest stone ellipse in the world. Further east the stone circle of Nabta Playa in Egypt had its importance further highlighted in a 2010 book by Robert Bauval & Thomas G. Brophy, Black Genesis. A 2012 illustrated paper reviews the range of megalithic monuments found across North Africa.(af)
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. More recently, Jean-Michel Hermans, a French ethnologist, also added support for a megalithic Atlantis. 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(ac).
Iberia is also home to very many megalithic structures of varying types. Recently, lower waters in a Spanish reservoir revealed once more the impressive 144-stone Dolmen-de-Guadalperal, situated roughly halfway between Madrid and the Portuguese border(z). Efforts are being made to ensure its preservation before the water levels rise again.
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, which seems consistent with a dearth of information regarding early history.
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? My opinion is that we are probably confronted with two unrelated mysteries – the disappearance of the megalith builders and the demise of Atlantis.
Parallel with the megaliths of the eastern Atlantic seaboard are the megaliths of North America(ab), particularly those of New England(ag). 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. Why would they even need such crude observatories if they had the technology and astronomical knowledge to travel across the cosmos?
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 at is that of Sjur C. Papazian(l). There is also a site(j) dealing specifically with the dolmens of Corsica and Sardinia.
In the Middle East dolmens stretch in a line from the Caucasus(s)(p) to Yemen with a remarkable concentration of them in modern Jordan(m), a fact which prompted a former Dutch ambassador to Jordan, Gajus Scheltema, to write Megalithic Jordan. 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).
A remarkable theory is presented by John M Jensen Jr to explain the function of dolmens throughout the globe, namely that they were constructed to protect from attacks by dinosaurs! This suggestion is part of a paper that claims that humans and dinosaurs co-existed(ad).
Another unusual claim comes from Yair Davidiy, a Brit-Am promoter, who wrote on their website – “Dolmens and Megalithic Monuments originated in Ancient Israel. Jeremiah 31:21 says that the Lost Ten Tribes will construct a trail of Megalithic Monuments from Israel to their places of exile and evidence of this path will enable them to return. Such a trail exists! It is the Trail of the Dolmens from the Middle East to the West.”(ae) As far as I’m aware Davidy has not explained the huge numbers of dolmens in places such as Korea and Japan!
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)
Some years ago, the renowned English archaeologist, Aubrey Burl, concluded after twenty years of study that French immigrants had built Stonehenge(aa). More recently, Mike Parker Pearson, a leading Stonehenge expert, has also endorsed this idea of a French origin for megalith building(x).
Archaeologist, Robert Hensey in his insightful First Light [1766.9] has also noted that “Construction of Breton passage tombs is likely to have ended by 3900 BC, almost certainly by 3800 BC, and the most recent evidence from Ireland suggests that passage tomb construction had not yet begun on this island by that time.”
Antequera is a city in Spain’s region of Andalucia. It is home to three megalithic structures (1) the “Dolmen de Menga”, (2)the “Dolmen de Viera” and (3) the “Tholos de Romeral” of which de Menga has been described as the largest and heaviest in Spain. They are collectively designated as a UNESCO World Heritage Site and described by that organisation as “These three tombs, buried beneath their original earth tumuli, are one of the most remarkable architectural works of European prehistory and one of the most important examples of European Megalithism.” The limited carbon dating that has been carried out would seem to indicate that construction took place sometime in the fourth millennium BC. Richard Cassaro has visited the site and posted an interesting report with many illustrations(ai).
The interesting claims of Schulz Paulsson, who places the origins of megalithic construction in 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 or south rather than from Ireland westward!
A number of megalithic sites situated around the world are reviewed on the illustrated megalithic builders website. Contributions from popular writers, such as Hancock, Bauval and Schoch are included(ah).
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).

Henriette Mertz (1898-1985) During World War II she worked as a code-breaker in the U.S. government’s cryptography department, while later she became an American patent lawyer in Chicago. Her interest in archaeology led her to be the first to propose that Odysseus, after wandering about the Atlantic, was the earliest European to set foot in America: an idea now taken up by others including Enrico Mattievich.
Mertz recognised that ancient America was host to guests if not residents from both east and west and has written in Pale Ink on the evidence for the existence of persistent pre-Columbian Chinese contacts. This book was later re-published as a paperback and retitled Gods from the Far East.
Her book The Mystic Symbol argues that some early Christians fled to America to escape persecution in the Roman Empire. Wayne N. May, the Mormon publisher of Ancient American, has also published a paper on the Mystic Symbol(b).
In a paper reprinted in the Ancient America website, Mertz decried the fact that thousands of inscribed artefacts recovered from mounds in the State of Michigan, between 1890 and 1920, were destroyed, in particular the controversial Newberry Tablet(c).
Her reputation as a serial heretic also forced her to privately publish a volume on Atlantis following rejection by twenty publishers. She gave a lecture on her views in London in 1964(d) and enjoyed extensive coverage in the Greek press including the serialisation of her book.
Her contention is that Atlantis was located in the southeast of the United States. She begins with the legend of the Seven Cities of Antillia and its depiction on the 1436 map of Andrea Bianco. A comparison of this map with a modern map of Florida convinced her that they referred to the same region. She discusses many aspects of Plato’s story and their compatibility with the archaeology, geography and legends of her chosen location. She also offers a map of Atlantis that encompasses the land bound by the Mississippi, Ohio and Potomac rivers as well as the Atlantic giving us the ‘island’ of Atlantis. To support this possibility she ingeniously suggests that Plato used the word ‘sea’ in the sense of being navigable and so was also applicable to rivers.
Mertz’s book, Wine Dark Sea, which claims that Homer’s Odyssey describes a very ancient trip to America, inspired the Austrian ethnologist, Christine Pellech, to expand on her work with a number of books on diffusionism together with a website on the subject. Unfortunately, Pellech’s books are only available in German but she has also established an English language magazine and website(a).>However, Pellech references Mertz’s theory but goes further with her contention that Homer’s Odyssey was a description of an ancient circumnavigation of the globe.(e)<
