Hughes, Bettany (t)

Bethany Hughes

Bettany Hughes (1968- ) is a well-known historian with a high media profile. She has presented one major TV documentary on the subject of Atlantis, specifically supporting aspects of the Minoan Hypothesis. This was Atlantis: The Evidence (Timewatch BBC TWO, 2010)(a) and more recently she has been trotted out to promote a new drama series Atlantis (BBC 2013).

She wrote a preview of this BBC series, for The Telegraph(b), which together with her earlier documentary still raises questions for me about her competence to deal with this subject at all. In her article she refers to the Atlantis story as a moral fable, ignoring the fact that not only were the ‘wicked’ Atlanteans destroyed, but so also were the ‘good’ Athenians.

She then alludes to Plato’s mention of the use of red, black and white stone in Atlantis. It is well known that this combination is common in volcanic regions and has been noted at a number of proposed  Atlantis sites; The Canaries, Bolivia, Morocco, Azores, Sardinia and southern Spain.

Next, Hughes tries to explain away the navigation hazard described by Plato, identifying it as pumice. Plato clearly describes mud shoals as the barrier. This would be fine, except that Plato also tells us that the hazard still existed in his day, a thousand years after the eruption. It is improbable, to say the least that pumice would have lingered for a millennium!

These miserable attempts to link Thera and Atlantis are bad enough, Hughes does not explain how Plato repeatedly refers to the Atlantean invasion coming from their base in the the west (Tim.25b & Crit 114c), while Thera/Crete is north of Egypt and south of Athens. Where were the Pillars of Heracles and where were the Minoan elephants?

I would expect a professional like Hughes to offer a more comprehensive review of ALL the information provided by Plato and not dismiss whatever conflicts with her opinion as “sheer fantasy”. This picking and choosing from Plato’s text is not good enough without any justification for her selectivity.




Volcanism is not part of the Atlantis story as related by Plato. His narrative clearly attributes the destruction of Atlantis and the Athenians to flooding and earthquake. Admittedly, flooding can be the result of some volcanic activity, but in the absence of any evidence to support this view in the case of Atlantis, the idea is only supposition. While most accept that Atlantis was named after its first king, Atlas, Frank Joseph’s fertile imagination suggests[104] that ‘the island of Atlantis was named after its chief mountain, a dormant volcano’. For those that place Atlantis in the Atlantic the idea of volcanic or seismic activity as the cause of the flooding of Atlantis AND Athens are hard pressed to suggest a location for this activity that would explain two catastrophes two thousand miles or more apart.

However, the red, white and black stone that Plato may be related to volcanic eruptions that produce rock of tufa (red), pumice (white) and lava (black). Pumice has been found at various locations in Egypt and identified as originating not only from Thera, but also from eruptions on the Greek islands of Nisyros and Giali as well as the Italian Lipari Islands(o).

Jelle Zeilinga de Boer and Donald Sanders are the authors of Volcanoes in Human History[681] in which they support the idea that the eruption on Thera was a factor in the development of the Atlantis story and also suggest a link with the Flood of Deucalion.

Nevertheless, a recent book by William Lauritzen, The Invention of God[745], makes a convincing case for accepting volcanic activity as the inspiration behind some of the imagery of ancient mythologies and most major religions. A recent article(i) on the BBC website expanded on this further. Lauritzen also suggests that the pyramids were meant to represent volcanoes.



The most active volcanic region of Europe is to be found in Italy, where Etna and Stromboli have been continuously erupting for thousands of years(b).  There is a report that a 6000 BC extreme eruption of Etna resulted in a tsunami 130 feet in height which swept the Mediterranean(c). However, the most devastating prehistoric volcanic eruption discovered so far seems to have been in Siberia 252 million years, which may have led to the most extensive mass extinction of life on earth(e). This is now rivalled by Tamu Massif in the Pacific mentioned below.

The cataclysmic volcanic eruption of Thera in the second millennium BC has had a strong level of support as the cause of Atlantis’ collapse, a view endorsed by recent television documentaries and an IMAX film. The Greek volcanologist, George Vougioukalakis, whose research is featured in the aforementioned film, is convinced that the eruption of Santorini offers the most rational explanation for the truth behind Plato’s story(a). However, he dissents from the recently expressed view that pumice found on the Northern Sinai Peninsula was transported there by a tsunami generated by the eruption of Thera and prefers to believe their transportation there was by normal sea currents.

Apart from Santorini, Jim Allen had initially proposed the Andean village of Quillacas, which lies on top of a volcano, as the site of Atlantis, but later found that the nearby site of Pampa Aullagas had a greater correspondence with the description of Atlantis. More recently Richard W. Welch has suggested the eruption of a supervolcano in the Atlantic as the cause of Atlantis’ demise. And so the idea of a volcanic destruction of Atlantis still has some support!

Since January 2011, Santorini has shown some signs of a volcanic reawakening(d).

In September 2013 studies revealed(f) what may be the location of the largest volcano ever to have erupted on our planet. It would have been the size of the British Isles and situated underwater in the northwest Pacific and known as Tamu Massif. It would have rivalled the Olympus Mons on Mars, but fortunately has been dormant for 140 million years.

March 2014 saw a post on Dale Drinnon’s website(g) take the linkage between Atlantis and a volcano rather further with the suggestion that “the capital city of Atlantis in Plato’s description was built in the caldera of an extinct volcano and that many of the features of the description are volcanic in origin.The “Poseidon’ temple is the pyramidal volcanic neck, an erosional feature that stood out like a conical mound some hundreds of feet in diameter and possibly some hundreds of feet high on the outside. there was a tunnel bored through this aligned East and West, to allow the sunlight in at the beginning and the end of the day for certain rituals.”

In December 2014 a report from Princeton University revealed that a massive series of volcanic eruptions 66 million years ago can be aligned with the extinction of the dinosaurs and should be included as part of the cause of that extinction along with the Yucatan meteorite impact(h).

The Laki volcano in Iceland erupted in 1783 killing 9,000 local people but more dramatically causing the Nile Valley population to be cut by a sixth, according to a study published by scientists at Rutgers, The State University of New Jersey. “The study is the first to conclusively establish the linkage between high-latitude eruptions and the water supply in North Africa”(j).

A 2015 report(k) suggests that a series of North American volcanic eruptions in 536 AD had such a detrimental effect on the climate of Europe that contributed to the demise of the Roman Empire.

Furthermore, there is now evidence(m) that the eruption of El Chicon volcano in Southern Mexico around 540 AD led to the disruption of the Maya civilisation. Can there be a connection between these two events?

However, David Keys in his book, Catastrophe[1130], has proposed that a massive eruption of Krakatoa around 535 AD caused disruption on a global scale. Matthew Toohey from the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, has suggested the possibility of a double event involving both El Chicon and Krakatoa!

Recently the longest (1,200 miles) continental volcano chain was identified in Australia(l).

The BBC reported(n) in 2016 that Deep-sea volcanoes are so remote, until recently we did not even know they existed” and although “We do not see them erupt, yet more than half of the Earth’s crust can be attributed to their dramatic explosions” and “In fact, the mid-ocean ridges form the largest volcanic systems on Earth. But as they are largely hidden from sight, they have long remained elusive.” 

*In July 2017, the BBC offered an interesting article on the potential ongoing threat from supervolcanoes around our globe(p)  and the inevitability of a future eruption.*



















Allen, J.M.

J.M. Allen, a Scotsman, worked in the 1970’s as an expert in satellite mapping with the British Royal Air Force. He was also a researcher of ancient measuring systems. The combination of these two interests led to a Jim Allenconviction that Plato’s Atlantis could be matched with a site in the Altiplano of Bolivia,which he outlined in his book Atlantis: The Andes Solution[0040].  Coincidentally, in the same year, Tony Morrison published an article entitled The Bolivian Atlantis(k-n).

Allen’s case is primarily based on the discovery of a vast canal network in the region together with aerial photography indicating concentric rings on the ground. His chosen site of Pampa Aullagus contains red, white and black rock reminiscent of the Atlantean masonry described by Plato.

In a TV documentary that focused on his theory it was suggested that the other nine kingdoms that comprised the Atlantean domain were probably to be found in South America.

Allen has also written Decoding Ezekiel’s Temple(a), which discusses ancient measuring methods.

In 2008 Allen delivered three papers to the 2nd Atlantis Conference[750] in Athens. All three papers are available online in pdf format(g)(h)(i).

2009 saw the publication of a second book, Atlantis: Lost Kingdom of the Andes[207] designed to reinforce his original thesis of Atlantis on the Altiplano of Bolivia. A trilogy was completed in 2010 with the publication of The Atlantis Trail (Kindle)which records his travels in the Andes in search of Atlantis(b). A small hotel is now being built in Pampa Aullagus to cater for increased number of tourists, no doubt in response to the work of Jim Allen.

In 2012, Allen published Atlantis and the Persian Empire, which is available to download as a free pdf file(c). This work is really just a reprise of his earlier writings. In this somewhat provocatively titled book he claims that Plato took the geography of the Atlantis story from the Andes, a theme he has been promoting since 1998.

However, he also maintains that the military history in Plato’s narrative was based on the war between Athens and the Persian Empire in the 5th century BC. Another of his more exotic claims is that the Sea Peoples were from South America. Allen devotes a considerable part of the book to ancient South American metrology and ends with a comparison of relative merits of the Altiplano versus Santorini as the inspiration behind Plato’s Atlantis story.

An extensive critique of Allen’s theories is offered by Timothy J.Stephany on his website(e). Nevertheless, although I consider Allen’s basic theory regarding Atlantis unacceptable, I find that part of his website showing images(f) of an extensive range of artifacts demonstrate most eloquently that South American civilisation was heavily influenced by distant cultures, both east and west.

Support for Allen’s views has continued into 2013(d), despite those elements that still conflict with Plato’s narrative: dating, dimensions and the improbability of an invasion of the eastern Mediterranean by a force from the west coast South America! However, I have found that in 1900, Peter de Roo devoted chapter seven of his History of America before Columbus[890.v1] to a review of the idea that at various times native Americans travelled eastward and among other things were responsible for the settling of Egypt!

Allen’s site offers an extensive article on the life and research of Posnansky, including excerpts from his work(j).
















Hübner, Michael

Michael Hübner (1966-2013) was a German researcher who presented to the 2008 Atlantis Conference in Athens, a carefully reasoned argument for placing Atlantis in North-West Africa on the Souss-Massa plain of Morocco. He had gathered and organised a range of geographical details and other clues contained in Plato’s text, which he maintained lead inexorably to Morocco. His paper is now available on the Internet(a) and a fuller exposition of his hypothesis has now been published in book form[632], in German, as Atlantis?:Ein Indizienbeweis, (Atlantis?: Circumstantial Evidence).

Hübner also published a number of video clips on his website in support of his theory. He begins with a lucid demonstration of a Hierarchical Constraint Satisfaction approach to solving the mystery. These clips offer a body of Sous Massaevidence which are perhaps the most impressive that I have encountered in the course of many years of rsearch. He matches many of the geographical details recorded by Plato as well as clearly showing rocks coloured red, white and black still in use in buildings in the same area. Hübner also shows possible harbour remains close to Cape Ghir (Rhir), not far north from Agadir (Plato’s ‘Gadeiros’). Although there are still some outstanding questions in my mind, I consider Hübner’s hypothesis one of the more original on offer to date.

However, I perceive some flaws in his search criteria definitions, which in my opinion, have led to an erroneous conclusion, although I think it possible that his Moroccan location may have been part of the Atlantean domain. Furthermore, I consider that his conclusions also conflict with some of the geographical clues provided by Plato.

Nevertheless, I am happy to promote Hübner’s website as a ‘must see’ for any serious student of Atlantology and I had looked forward to the publication of his book in English. In the meanwhile a video on YouTube(b) gives a good overview of his theory.

The 2011 Atlantis Conference saw Hübner present additional evidence(c) in support of his theory in which he translated his HCS method into a series of mathematical formulae.

Tragically, Michael Hübner died in December 2013 as a result of a cycling accident. However, he left a valuable contribution to Atlantis studies.

Mark Adams met Hübner shortly before his death, so in March 2015 when Adams’ book, Meet me in Atlantis, was published, the ensuing media attention probably gave Hübner’s theory more publicity than when he was alive!

Although I have always been impressed by Hübner’s methodology, my principal objection to his conclusions is based on the fact that all early empires expanded through the invasion of territory that was contiguous or within easy reach by sea. This was a logical requirement for pre-invasion intelligence gathering and for the invasion itself, but also for effective ongoing administrative control. Agadir in Morocco is 2000 miles from Athens and so does not match Hübner’s very first ‘constraint’, which requires that “Atlantis should be located within a reasonable range from Athens.”

He arbitrarily decided that ‘a reasonable range’ was within a 5,000 km radius based on the fact that the campaigns of Alexander the Great reached a maximum of 4,700 km from Macedonia. However, he seems to have missed the point that Alexander began his attack on the Persian Empire by crossing the Hellespont (Dardanelles), which is less than a mile wide at its narrowest. As is the case with all ancient empires, Alexander expanded his Macedonian empire incrementally, always advancing through various adjacent territories. Alexander’s aim was to conquer the Persian Empire and having done that, he continued with opportunistic expansionism into India. My point being, that ancient land invasions were always aimed at neighbouring territory, then, if further expansion became possible, it was usually undertaken immediately beyond the newly extended borders. Alexander, did not initially set out to conquer India, but, as he experienced victory after victory, his sense of invincibility grew and so he pushed on until the threat of overwhelming odds ahead and opposition within his own army persuaded him to return home.

Similarly, naval invasions are best carried out over the shortest distances for the obvious logistical reasons of supplies and the risk of inclement weather and rough seas. There are many extreme Atlantis location theories, such as America, Antarctica and the Andes, from which it would have idiotic to launch an attack on Athens, in excess of 3,000 years ago, particularly as there were more attractive and easier places to invade, closer to home, rather than Athens, from where up-to-date pre-invasion military intelligence would have been impossible. Hübner’s Agadir location being 3,300 km from Athens is not as ridiculous as the Transatlantic suggestions, but it is still far too great a distance to make it practical. If expansion had been necessary, nearby territory in Africa or Iberia would, in my opinion, have offered far better targets!

*If I’m asked to say what I consider a ‘reasonable striking distance’ for a naval invasion to be, I would hazard a layman’s guess at less than 500 km. When the Romans wiped out Carthage, the used Sicily as a stepping-stone and then had to travel less than 300 km to achieve their goal. But there are many variables to be considered; weather, time of year, terrain and the opposing military, which I think should be left to experts in military history and tactics. However, I must reiterate that 3,300 km is not credible.*

My second criticism of Hübner’s presentation is his claim that Plato described Atlantis as being ‘west’ of Tyrrhenia, which is based on his assumption that Atlantis was situated on the Atlantic coast of Morocco and consequently believed that Atlantean territory extended from there westward until it met Tyrrhenia. In fact what Plato said, twice, was that Atlantis extended as far as Tyrrhenia (Timaeus 25b & Critias 114c), The implication being that Tyrrhenian territory, which was situated in central Italy, was adjacent to part of the Atlantean domain, which, I suggest, was located in southern Italy. This would have left the Greek mainland just over 70 km away across the Strait of Otranto, well within striking distance. I think that it is safer to think of the Atlantean alliance having a north/south axis, from Southern Italy, across the Mediterranean, including Sicily together the Maltese and Pelagian Islands and large sections of the Maghreb, including Tunisia and Algeria.

A graphical demonstration of how HCS works is available on a YouTube clip(d).

Red, White and Black (m)

The Red, White and Black stone which Plato said had adorned the buildings of its port city, have led Atlantis seekers to eagerly follow up this apparently obvious clue. However, as with so many aspects of the Atlantis story, this particular detail does not provide us with anything like a clear pointer to any specific location.

Jürgen Spanuth relates[015.125] how the ancient Canarians decorated their temple with red, white and black rock, the colours of tufa, pumice and lava. The cliffs of Santorini are also known to display red, white and black rock. These three materials are frequently found in the vicinity of volcanoes(b) and may be considered a valuable clue to the location of Atlantis.*[However, this combination of rock colours is not exclusive to volcanic localities as Jim Allen has demonstrated at Pampa Augallas in the Andes and Peter Daughtrey at his Silves site in Portugal[0893.120].]*

Although Atlantis was destroyed by an earthquake, volcanoes are often located in the same general region such as in the Central Mediterranean which is both seismically and volcanically very active and, in my opinion, the prime candidate as the home of Atlantis. This view is endorsed by Plato himself who twice (Tim.25b & Crit.114c) told us that the territory of the Atlantean alliance stretched from North Africa as far as Tyrrhenia in Italy. I further propose that this was on a north/south axis.

Jim Allen has found the same three rock colours at his Bolivian site and further afield, Ian Wilson points out[185] that red, white and black bricks were used extensively in Çatal Hüyük. Not to be excluded, Diaz-Montexano has produced photos on his website of pre-Roman structures near Gibraltar that incorporate red, white and black blocks in their construction. Jonas Bergman has indicated that similarly coloured stone is to be found in Morocco. Other locations include the Azores, Algeria and Sardinia.

Some(a) have sought to link the red, white and black of the Nazi swastika with Plato’s reference.




Sardinia is a region of Italy and after Sicily is the second largest island in the Mediterranean. Before the end of the last Ice Age, Sardinia had been joined to the European mainland because of the lower sea levels, which provided an easy access route for early settlers. Recent genetic studies revealed an exceptionally high proportion of the population is seemingly descended from people who have occupied it since the Neolithic and Bronze Age, between 8,000 and 2,000 years ago.”(al)


Known to the Greeks as ‘Hyknusa’, during its long history, Phoenicians, Etruscans, Greeks and Romans have all left their mark on Sardinia. Before that, the megalith builders(j) were active on Sardinia and Corsica. A comprehensive history of Sardinia from the time of Atlantis is available online, in Italian and English(m). There is a tradition that Sardinia got its name from Sardus, son of Hercules(aa).

Sardinia’s important position in the ancient world was suggested by Mark McMenamin, a geologist at Mount Holyoke College in Massachusetts, who announced in Numismatist Magazine in November 1996, that he believed that the Carthaginians produced gold coins, between 350 and 320 BC, depicting small maps of the Mediterranean world with India to the east and America to the  west(e). When computer enhancement was applied to the images on some of those coins, he was amazed to note how the strange markings on them resembled maps made by Ptolemy, the Greek astronomer and geographer. The maps show what appears to emphasise the Mediterranean region, with Sardinia as a dot in the centre. The north coast of Africa appears at the bottom with Europe at the top, above the Phoenician homeland and India. The Strait of Gibraltar lies to the west; after that is the landmass of America. Some sceptics have been convinced of the correctness of McMenamin’s interpretation after seeing the enlarged images.

It has been suggested(p) that the ancient city (2000-1400 BC) of Nora, just south of today’s Pula, was thriving long before the arrival of the Phoeniciansin the 8th cent. BC.. It appears that contact between Sardinia and its trading partners suddenly ceased around 1400 BC, until the arrival of the Phoenicians. Phoenician inscriptions, one dated to the 11th century BC, were been found at Nora(q) in 1773. These inscriptions refer to Pygmalian, King of Tyre and to a battle between Sardinians and Phoenicians at Tarshish!

It has been postulated that the Shardana, one of the Sea Peoples of the 2nd millennium BC, gave their name to Sardinia and were probably the builders of the hundreds of Nuraghi there. Leonardo Melis, a native Sardinian, has studied and written at length on the subject. David Rohl, the archaeologist and advocate of revising generally accepted ancient chronologies, has argued[0232] that the Shardana were in fact originally from Sardis in ancient Anatolia and that they migrated westward to Sardinia following the collapse of the Hittite Empire.

Apart from the enigmatic remains of the nuraghic period, Sardinia has presented archaeologists with a greater mystery in the form of a structure at Monte d’Accoddi that closely resembles a Mesopotamian ziggurat. The earliest parts of the monument have been dated to circa 3000 BC – the same period during which comparable step pyramids were being built in Mesopotamia. Leonardo Melis has speculated that the name of the site, Accoddi, may be connected to the Akkadian civilisation. Step pyramids are also found on Sicily(c) and additionally the Le Barnenez cairn(ad) (4500-4700 BC), in Brittany, has a superficial resemblance to some of the Western Mediterranean ‘pyramids’.

sardinia mapRecent discoveries of statue menhirs on Sardinia have suggested that in the 4th millennium BC the island was part of a culture which spread from the Black Sea to the Atlantic(f).

Statue menhirs are also found on adjacent Corsica.

The end of the 18th and the beginning of the 19th centuries saw Antoine Court de Géblin and Delisle de Sales suggesting Sardinia as a remnant of Atlantis. However, the first person in more recent times to promote a Sardinian Atlantis was Paolo Valente Poddighe, who did so in 1982, but, it was 2006 before he published a book[711] supporting this claim.

It was nearly another twenty years before Robert Paul Ishoy was the first to have a website(a) that promoted Sardinia as the site of Atlantis. His contention is that Atlantis was a powerful state based in Sardinia that controlled most of the western Mediterranean and was at its peak between 2000 BC and 1400 BC. Ishoy further contends that the Keftiu, Atlantean and Nuraghi cultures were all one. He contends that they made attempts to conquer the principal civilisations of eastern Mediterranean including the Minoans, Athenians and Egyptians. During one of these attacks the Athenians with the unexpected support of floods and earthquakes defeated the Atlanteans. Ishoy has been planning an expedition to Sardinia to seek further evidence in support of his thesis.

In 2002, the Italian journalist, Sergio Frau, published a book[302], in Italian, which firmly located Atlantis just south of Sardinia, where it is now covered by water(ah). He argued that the Pillars of Heracles were at one time located as a boundary marker at the Strait of Sicily and later moved to Gibraltar as the Greek awareness of the western Mediterranean developed with expanded trade. Frau attributes this change of location to the geographer Eratosthenes who flourished more than a century after Plato. Understandably, his theory has been greeted with the usual hail of criticism but was given support by UNESCO when it organised a symposium on the theory in Paris in 2005 followed by an exhibition in Rome the following year. In the interest of balance, Thorwald C. Franke’s critique(n) of Frau’s work is required reading, as well as a 21-point refutation of his book signed by 71 Sardinian historians, geologists and archaeologists(w).

In June 2015 Frau together with number of Italian scientists joined him when he visited Sardinia(x). They included historian Mario Lombardo; archaeologist Maria Teresa Giannotta; Claudio Giardino, a specialist in ancient metallurgy; cartographer Andrea Cantile; archivist Massimo Faraglia; and Stefano Tinti, a geophysicist and expert on tidal waves. Their objective was to study the evidence for a huge tsunami inundating the southern part of the island in ancient times.

A report in The Guardian (15/8/15) noted(y) that “Professor Tinti explained that until the 1980s no one was aware that tidal waves had occurred in the Mediterranean. But since 2004 scientists have identified 350 events of this type over a 2,500-year period,” and regarding the Sardinian tsunami “So what would have been required in our case?” he then asked. “We’re talking about a huge volume of water, some 500 metres high [the elevation up to which the nuraghi were affected]. Only a comet could do that, if the impact occurred very close to the coast and in a very specific direction,” he asserted. An event of this sort may have occurred near Cagliari, with the resulting wave devastating the plain of Campidano.”

Afterwards, Frau’s claim was given further attention(u) when an exhibition in the museum in Sardara, which focused on that catastrophe which hit the island around 1175 BC. This cataclysm mainly effected the southern portion of Sardinia covering it with a layer of mud. A geophysicist, Stefano Tinti, claims that the most likely cause of such an incursion would be an enormous tidal wave resulting from the impact of a comet in the Mediterranean. It was not surprising that Jason Colavito debunked(v) any linkage of Sardinia with Atlantis as well as the claim of a cometary impact, but avoided offering any explanation for the layer of mud.

A French website offers an interesting titbit regarding the extent of the mud, noting that A nuraghe was discovered not far from the Sardinian town of Barumini.Les archéologues ont mis 14 ans pour ôter les 12 mètres de boue qui recouvraient ce monument. The archaeologists took 14 years to remove the 12 meters of mud that covered this monument”.

An alternative view of Sardinia and its nuraghi was offered(z) by Brian Cairns on the Thunderbolts website, where he claimed that the nuraghi were constructed to offer protection from cosmic electrical strikes. In his conclusion he states that “while the evidence above is circumstantial, it seems that Sardinia had a very active electric environment.”

The late Vittorio Castellani who had advocated locating Atlantis in the British Isles was so impressed by Frau’s book that he changed his mind and supported the idea of a Sardinian Atlantis. Another keen supporter of Frau is Mario Tozzi who has also suggested that if Sardinia was Atlantis that the mysterious Etruscans may have been Sardinians(r)(s). Further support has come from Mario Cabriolu and architect Paolo Macoratti, who identifies the Plain of Campidano with the Plain of Atlantis and locates the Atlantean capital further south in the Gulf of Cagliari, illustrated on a map on the site(t).

As Sardinia is still very much above water, it might seem an unlikely choice as the location of Atlantis. However, if it is accepted that the Pillars of Heracles were in fact situated at the Strait of Sicily, there are a number of features on Sardinia that would support the theories of Ishoy and Frau. There is evidence that the large plain of Campidano was inundated, from the south, by a tsunami, following an earthquake, in the Central Mediterranean in the 2ndmillennium BC. Professor Mauro Perra has argued against this(o) using extensive stratigraphic evidence. However, this tsunami also covered Punic and Roman remains indicating a much later date.

Furthermore, there are mountains protecting the plain from cold northern winds and rich mineral deposits are also found in the locality. Sardinia was well-known in ancient times as a source of silver as well as copper, iron and lead(af). There is also some evidence that a small but important quantity of tin was available on the island according to Stephen L. Dyson and Robert J. Rowland jnr., in their recent history of Sardinia[1530]. The excellent website comments that Sardinia can scarcely have been occupied by the Phoenicians for anything but its metals. The southern and south-western parts of the island, where they made their settlements, were rich in copper and lead; and the position of the cities seems to indicate the intention to appropriate these metals.

In 2010, Giuseppe Mura published a book of nearly 600 pages, in which he identifies the Gulf of Cagliari as the location of the Pillars of Heracles that previously led to a channel which gave access to the Plain of Campidano, which he claims(g)(h) was the Plain of Atlantis described by Plato.

Furthermore, another young Sardinian has recently pointed out that colours associated by Plato with Atlantis, namely red, white and black, are found naturally on the island as well as excavated buildings of the Nuraghic period being painted in red and black stripes. The Sardinian regional flag also uses these colours.

We can expect that the future will see further development of the Sardinian Theory, which shows more promise than many of the other suggested locations.

For those interested in reading more about the history of Sardinia from its prehistory until the present should visit Claudio de Tisi’s website(i) (In Italian and English). It includes a review of Sergio Frau’s book on Atlantis. In 2011, travel writer Angela Corrias wrote a two-part article)(ab)(ac), which also includes a review of Frau’s theory.

There would appear to be growing support from local researchers on the island for the a Sardinian Atlantis . One of the more recent is Giorgio Valdés who equates Sardinia with Tartessos and Atlantis. This idea of Sardinia and Tartessos being identical goes back to the middle of the 20th century, when Wikipedia(k) tells us “that W.F. Albright (1941) and F.M. Cross (1972) suggested Tarshish was Sardinia because of the discovery of the ‘Nora Stone’ or ‘Nora Fragment’.” An extensive article(l) on the Nora Stele, in Italian, was written in January 2014, based on a translation by Jose Stromboni.

In 2013, Marin, Minella & Schievenin stated[972.43] that Sardinia was called Tartessos in ancient times, unfortunately, without providing any references.

In August 2016, Frau’s theory received a further spurt of publicity with an interview in Sputnik News, which was followed a few days later by the announcement that National Geographic was planning a documentary, co-produced by James Cameron and Simcha Jacobovici, based on Robert Ishoy’s Atlantis in Sardinia theory(ae).

However, Diaz-Montexano is also certain that the documentary will focus on his theory(ai). In the end, both theories featured in what turned out to be a disappointing documentary.

Perhaps more noteworthy is also a local wine entitled Critias – Atlantis Terre di Sardegna!
