    September 2023. Hi Atlantipedes, At present I am in Sardinia for a short visit. Later we move to Sicily and Malta. The trip is purely vacational. Unfortunately, I am writing this in a dreadful apartment, sitting on a bed, with access to just one useable socket and a small Notebook. Consequently, I possibly will not […]Read More »

    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 »

Antikythera Mechanism *

AntikytheraThe Antikythera Mechanism is one of the most remarkable artefacts ever discovered. It was found by sponge divers off the coast of the Aegean island of Antikythera just over a century ago. The device consists of four fragments with a total of 30 bronze gears.

Very little intensive investigation was done until the early 1950s when Derek J. de Solla Price (1922-1983) a professor at Yale University undertook a study of the Mechanism. His conclusions were published in several papers including Gears from the Greeks, now available as a pdf file(r).

It was originally dated to the 1st century BC and had been ascribed by some to the Greek astronomer Hipparchos, but recent research by Professor Alexander Jones of New York’s Institute for the Study of the Ancient World has pushed this back to the 2nd century BC(b). Jones dismissed as ‘desperate’ a suggestion by Dr Jo Marchant, that the mechanism had been part of a timepiece that possibly controlled the sequential appearance of figures to indicate seasons. Marchant is the author of Decoding the Heavens: Solving the Mystery of the World’s First Computer[1460].

However, there is an inclination to look at the Antikythera in isolation and ignore the fact that as early as the 5th century BC “the Greeks were able to design and build self-directed machines. There is evidence that they built a bronze automaton of an eagle and a dolphin that were on display at the Olympic Games. Many of the automatons developed were only toys, such as the birds invented by Archytas (c. 428–347 BC). However, one inventor known as Philon of Byzantium (c. 280 BC–220 BC), invented a repeating crossbow.

It seems that in the Hellenistic period, developments in automation really advanced. In this period inventors used a complex system of levers, pulleys and wheels to build self-directed machinery. Rhodes became well known for its machine and there were two automatons in one of its main squares, to impress visitors.”(aq)  To me, it appears that Antikythera Mechanism is just a natural development of the mechanical skills that had emerged at that time and was also used later by the Romans, but not to the same extent.

“Mark Anthony had an automaton of Julius Caesar, made of wax, depicting Caesar rising from his deathbed and turning, slowly, to display his twenty-three bleeding wounds to the crowd. This started a riot and led to Brutus and the other killers of Caesar fleeing the city.” (aq)

Furthermore, we should not think that the Mechanism is unique as similar devices were referred to by the Roman orator Cicero (106-43 BC) in his De Re Publica 1.14.(ar)

A report(n) published in November 2014 revised further the date of the Mechanism’s creation back to 205 BC. Further research by the American historian James Evans led him to offer the claim that the mathematics on which this machine is based (more precisely the arithmetic) does not correspond to the Greek, but does to the Babylonian(ai). The level of ancient Greek celestial knowledge is also being reappraised in the light of a recent study of a decorated cup of a type known as a skyphos(o).

The superiority of Babylonian mathematics was supported by a recent study of a 3,700-year-old tablet known as Plimpton 322. The tablet was discovered around a century ago by Edgar J. Banks in what is now southern Iraq. Australian scientists from the University of New South Wales, Sydney have now demonstrated that the tablet is the world’s oldest and most accurate trigonometric table, predating the Greek astronomer Hipparchos by over a millennium(z).

The Mechanism is a clockwork device for calculating astronomical events. A number of models have been built(c), based on the evidence of the fragments discovered and further study is continuing. Even Lego was used by designer Andrew Carol to build a replica of the mechanism(e)(d). Furthermore, in November 2011 Hublot, the Swiss watch manufacturer, revealed(h)  that they had designed a wristwatch based on the Antikythera Mechanism.

In 2008, it was announced that writing engraved on the housing indicated the locations of athletic games; The Games dial shows six competitions, four Panhellenic (Olympics, Pythian, Isthmian, and Nemean) plus Naa (Dodona) and very probably Halieia (Rhodes)(w).

At the same time, a possible connection with the renowned Archimedes was posited by some commentators(f). An even more remarkable feature was the clever use of two gears, one positioned slightly off-centre in relation to the other, allowing the mechanism to track the apparent speeding up and slowing down of the moon each month, resulting from its elliptical rather than circular orbit(g).

The question that has now arisen is whether “It is possible that the mechanism is based on heliocentric principles, rather than the then-dominant geocentric view espoused by Aristotle and others.”(ab)

Dr Minas Tsikritsis, a Cretan researcher, maintains that an object from the Minoan Age discovered

Paleokastro Object

in 1898 in the Paleokastro site on Crete, was in fact “a cast for building a mechanism that functioned as an analog computer to calculate solar and lunar eclipses.”(i) This was nearly a millennium and a half before the Antikythera Mechanism was manufactured, which would make it Minoan.

Some commentators, such as David Hatcher Childress, see the Antikythera device as just another piece of evidence of more complex scientific knowledge among early cultures than is usually accepted and that by extension the possibility of a technologically advanced Atlantis[620].

In his 2014 book, The Stonhenge Codes[977], Professor David P. Gregg, has devoted an appendix to the sophistication of the mechanism, in which he discusses the functions of individual shafts and gears. His objective is to show that its complexity is comparable to that of Stonehenge and that our view of early Greek mathematics and astronomy requires revision. His book can be read online(j).

A January 2019 article elaborates further on the Mechanism’s function as a predictor of possible eclipses(ae). It may be worth recalling that in the 1960s, Gerald Hawkins suggested that the 56 Aubrey Holes at Stonehenge were also used as eclipse predictors [1613]+, an idea endorsed by Fred Hoyle [1614]+. John Edwin Wood in Sun, Moon & Standing Stones [1951.76] preferred Hoyle’s method over Hawkin’s. A 1999 paper has proposed a simpler method than those put forward by either Hawkins or Hoyle(ap). This matter is still the subject of debate(af).

More recently (Feb.2020), Alexander Jones, has offered a highly technical investigation((ag) of the possible date for the construction of the Mechanism and concluded that “while the dating of the eclipse series inscribed on the Mechanism’s Saros Dial taken by itself may suggest a dating of the Mechanism’s construction somewhere within the 76 years after 205/204 BCE, other considerations such as the archaeological context in which it was found, together with what is otherwise known of the development of Greek astronomy in the Hellenistic period, may outweigh this preference and favor a later date.”

Opus Gemini, a trilogy of novels by Andreas Möhn, based on the Antikythera Mechanism was published in the Kindle format in September 2013 and is also available in other formats. Further information and updates are available on his website(m).

The following website(a), will keep you up to date on related developments.

New Scientist announced on June 4th, 2014(k) that plans have been made to dive again to the Antikythera wreck in the hope of finding a second ‘mechanism’, using a ‘wearable submarine’. The Sept/Oct season of 2014 ended with evidence that the ship had been up to 50 metres long, making it the largest ancient shipwreck ever discovered(l).

The February 2015 edition of Smithsonian Magazine gives an up-to-date review of the scientific studies of the Mechanism(p). In June 2016 the Smithsonian returned to the subject with an article(u) devoted to the extensive writing, some less than a millimetre tall, revealed by CT scans on virtually every surface. This recent study indicates that the Mechanism also appears to have an astrological purpose! These investigations also pointed to the Aegean island of Rhodes as its place of manufacture.

In August 2016, further dives confirmed that “the ancient cargo in Antikythera, still full of goods, is located at a depth of around 60 metres, making the work of divers particularly difficult. They only have 20 minutes to explore the sea. To help them, a set of submarine drones are currently being developed for next year. They will detect metal and make real-time analyses of the data collected.”(v)

Another paper(t) in 2015 offers a more complete history of the Mechanism’s discovery and subsequent studies.

In 2017, further objects were recovered from the wreck, including parts of a metal statue, as well as compacted metal objects that have yet to be cleaned and separated. It seems that the site has not yielded all its secrets yet(aa). There are indications that there may be as many as nine statues still to be recovered, which are under huge boulders that overlie the metal objects and may have tumbled onto the wreck during a massive earthquake that shook Antikythera and surrounding islands in the 4th century AD.

A physically smaller but important discovery was that of the part of a gearwheel in Olbia, Sardinia in 2006. Giovanni Pastore, an Italian mechanical engineer, has studied the object and written an article(s) on it for the Ancient Origins website, where he informs us that it is dated between the mid-2nd century and the end of the 3rd century BC, has revealed a very important surprise: the teeth have a special curving which makes them extraordinarily similar to the mathematically perfect profile used in modern gears. Moreover, the unusual composition of the alloy (brass) was completely unexpected.”

Further important technical information about the Olbia gearwheel is available on the Italian website(ak). Pastore explained, “that those who made the Wheel of Olbia had very advanced knowledge, from mathematics to astronomy, so the manufacturer of the gear wheel of Olbia has anticipated the knowledge of almost 2000 years.” He concluded that the gearwheel indicates that there was a slow decay of scientific thought that lasted over time until the modern era.”

Inevitably, the suggestion has been made that first-century BC Greeks could not have created the Mechanism without alien assistance as the following quote shows; While many experts try to offer explanations for how this device could have been conceived, designed and built, all their concepts fail the tests of logic. There is only one possible explanation. Beings with advanced knowledge of astronomical bodies, mathematics and precision engineering tools created the device or gave the knowledge for its creation to someone during the first century B.C. But the knowledge was not recorded or wasn’t passed down to anyone else.(x) It is also humorously ‘suggested’ that the early Greeks had laptops!! (q)

For the technically minded, a clockmaker, known just as ‘Chris’, has an extensive website(y) where he has a number of videos illustrating how he has reconstructed copies of individual components of the Antikythera Mechanism.

In 2018, Charles River Editors have produced a fascinating volume [1585] that offers a valuable history of the Mechanism and the various efforts to determine its origin and purpose.

A few days ago (17.11.18) it was announced that a missing piece of the Mechanism had been found near the site of the original finds(ac). However, Smithsonian Magazine swiftly adopted a more cautious approach(ad), claiming that it was probably not a piece of the Mechanism! Watch this space.

In March 2021, further investigation revealed that the Mechanism also included “a complex planetarium on the ancient device’s face”, “that matches all the data and culminates in an elegant display of the ancient Greek Cosmos”, “showing the motion of Mercury, Venus, Mars, Jupiter, and Saturn—each represented by a small gem—along with the path of the Sun, the phases of the Moon, and the positions of the Zodiac constellations.”(ah)

The January 2022 edition of Scientific American has an article by Tony Freeth, in which he reviews the discovery and the gradual realisation of the purpose of the Mechanism, concluding with the following paragraph – “with the Antikythera mechanism, we are clearly not at the end of our story. We believe our work is a significant advance, but there are still mysteries to be solved. The UCL Antikythera Research Team is not certain that our reconstruction is entirely correct because of the huge loss of evidence. It is very hard to match all of the surviving information. Regardless, we can now see more clearly than ever what a towering achievement this object represents.” (al)

Tony Freeth et al published a paper(as) in August 2021 explaining how his team offered a reconstruction of the Mechanism designed to take account of the fact that it is “now split into 82 fragments, only a third of the original survives, including 30 corroded bronze gearwheels.

In April 2022, an article in Live Science reported that “The mysterious Antikythera mechanism, thought by some to be the world’s first computer, was first ‘started up’ on Dec. 22, 178 B.C., archaeologists have now found.” (am)

Work continues at the underwater site as part of a five-year project, coordinated by the University of Geneva. Since the ship was transporting the highest quality of luxury goods, there is a very real possibility of unimaginable finds, similar in importance to the Mechanism.”(an) In June 2022 the discovery of a marble head of Hercules was announced(ao).

Amazons is the name used by classical writers(k) to identify two matriarchal nations living near the Black Sea and in ancient Libya, but at apparently different periods. An extensive website on the subject associates the Amazons with three locations; Lake Tritonis(j) , the Greek island of Lemnos(i) and the River Thermodon, now known as Terme Çay, in northern Turkey(h).

Accounts relating to these remote times are understandably vague but one tale describes the Libyan Amazons as waging war against the Atlanteans, a race who lived in a prosperous country with great cities.

Attention has been drawn to the fact that the Berbers, also known as Amazigh in North-West Africa have a matriarchal culture. The possibility of an etymological connection between Amazon and Amazigh was suggested by Guy C. Rothery (1863-1940) in his 1910 book, The Amazons[1393]  , and recently endorsed by Emmet Sweeney in his Atlantis: The Evidence of Science[700]. In 1912, Florence Mary Bennett published Religious Cults Associated with the Amazons[1548], which has been republished in recent years.

Another matriarchal society in the same region has also been suggested for the Maltese Islands(h).

Sir John Chardin (1643-1713) a French-born traveller and merchant reported that a tribe of Amazons still existed in the Caucasus in the 17th century(d).

Although the idea may be seen as fanciful, recent archaeological discoveries have provided evidence of female warriors in ancient times in parts of the former Soviet Union. The archaeologist Jeannine Davis-Kimball has written of her investigations[045] into the subject. Peter James offers[046] a solution to the existence of two locations for the Amazons. He believes that the original Black Sea location is correct and that the transference of the story to North Africa was the result of the ‘libyanising’ intent of Dionysus of Miletus, who was later quoted by Diodorus Siculus in his account(f) of the Amazons.

. James offers this explanation as part of a larger relocation of mythologies to more westerly locations. Other interesting views of the Amazon mystery can be found on a number of websites(a)(b).

Lewis Spence advanced the imaginative view [259.49] that the Amazons were not women at all, but men whose appearance was considered effeminate by some commentators. A more rational explanation on offer is that the males of some peoples had little facial hair or shaved (such as the Hittites) and were possibly described by their more hirsute enemies as ‘women’.

The popular idea that the Amazons were single-breasted, man-hating warriors has recently been comprehensively debunked by Adrienne Mayor in her latest book, The Amazons[1043] .

>Even more eyebrow-raising is the suggestion that Amazon warriors existed in South America based on 16th century reports and modern research(c). Columbus, in a 1493 letter to Luis de Sant’angel, refers to an island named Matininó, which was inhabited only by women(m), armed with bows and arrows. Hernán Cortés also filed a similar report.<

The Smithsonian magazine published a useful overview(e) of the history of the Amazon story in the April 2004 edition and in September 2011 revealed the story of the little-known female warriors of Benin (formerly Dahomey), numbered in their thousands, who were active during the 17th, 18th and 19th centuries. The BBC published an article in August 2018 on their history and their modern day descendants(l) .















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 middle 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[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].

Megalith building in North Africa has been documented for over a century. The Hill of Graces[1566] 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[1508]. A 2012 illustrated paper reviews the range of megalithic monuments found across North Africa(af).

We must, of course, not omit the greatest megalithic monuments of all, namely, the Egyptian pyramids and particularly those at Giza. The apparent sophistication of their builders was greatly enhanced by the introduction of the Orion Correlation Theory (OCT) by Robert Bauval.

In a paper(at) published on Graham Hancock’s website in 2022, Freddy Silva proposed an additional OCT – in Scotland. He suggested that the Pyramids of Giza, and by extension, Orion’s Belt matched the layout of the three stone circles of Stenness, Brodgar and Bookan. In the same paper, he goes further identifying other megalithic monuments in Scotland with counterparts in Sardinia and Armenia! OCT is not without critics.

The megaliths of North Africa are not the only monuments to adorn that continent  Atlantisforschung drew my attention to a number of short articles by William Corliss (al)(am)(an) highlighting what has become known as the Senegambian Complex and are now a UNESCO World Heritage site(ak).

Paul Dunbavin in his Atlantis of the West [0099] and Towers of Atlantis [1627] promotes the idea of a megalithic Atlantis centred off the coast of Wales in what is now the Irish Sea. In 2022 Dunbavin recorded(ao) that “In a review of the “Pathways to the Cosmos” conference held at Dublin Castle in September 2018, Liz Henty makes some perhaps surprising comments. She notes that this is the first such conference where archaeologists and archaeoastronomers have combined to broadly agree that some Neolithic monuments in Britain and Ireland were astronomically aligned(ap).

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.

The most recent (2022) attempt at linking the megalith builders with Atlanteans has come from a disappointing book by Thomas Sheridan and Neil McDonald [2070], in which their starting point is the magnificent megalithic remains found in the Orkneys that are situated just north of the Scottish mainland.

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) Nobody seems to have put forward the idea that megalith building might have spread from America to Europe! Is it such a wild suggestion?

Johnni Langer has published a lengthy paper on the prehistoric megaliths of South America and in particular Brazil. Generally speaking references to South American megaliths focus on Tiwanaku or Cuzco, considered to be relatively recent. However, Langer’s article has drawn attention to structures further afield in Brazil that suggest astronomical alignments(ar). Brazil continues to reveal more megalithic structures, unfortunately, in some cases only because of deforestation(au). The Brazilian discoveries have only added to the who and when questions relating to megaliths generally and whether there is any possible connection between the megalith builders and Atlantis.

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[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).

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! Professor W.A. Liebenberg has written a longer piece(aq) on the ‘Lost Tribes’ as the builders of the megaliths. However, since the megalithic building period is generally accepted to have lasted from around 4000 BC until 1500 BC, this created a problem for Davidy and Liebenberg. The disappearance of the Lost Tribes is dated to around 700 BC leading to their dispersal and proposed megalith building as they travelled. D & L include Newgrange (3200 BC) among their monuments and that is where their difficulties begin. Both claim that before 700 BC the year was 360 days in length (after Velikovsky [037.128]) rather than our present 365 days. They argue that if Newgrange (among other monuments) had been built when we had a 360-day year the sun would not still light up the interior at the winter solstice. Therefore, they conclude that most megaliths were erected AFTER 700 BC!>An alternative conclusion is that the idea of a 360-day year is flawed and that a date BEFORE 700 BC must be correct!<

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 presents, 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.”

>Archaeologist Ashleigh Murzewski published a 2012 paper (av) on the significance of megalithic monuments in Atlamtis Europe and noted that “the construction of megalithic monuments in Atlantic Europe are not restricted to a single purpose, nor how they reflect one aspect of the community that built them.”<

Jean-Michel Hermans contends that the megalith builders of Brittany had originated in the Caucasus and after a sojourn in what is now Bulgaria moved to Brittany after 5000 BC(aj).

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).
