There is an Irish tradition that names Murias as one of the four cities of the Tuatha dé Danaan(b), who came to Ireland a thousand years before the Celts.
The pre-Hellenic Greeks were known as the Danai and were, according to an Egyptian source, the descendants of Danaus. Furthermore, the Danai have been linked with the legendary Tuatha dé Danaan of Ireland as well as the Shardana of Sardinia, who are thought to be part of the Sea Peoples.
A popular belief is that the Tuatha dé Danaan were descendants of the Hebrew tribe of Dan. Walter Baucum(c) and in particular Yair Davidiy(d) have written extensively on the people of Dan and their possible migration routes.
(a) Atlantis, A New Concept. Pt.1, Atlantis May-June, 1974
Horned Helmets have been worn by various warrior groups from ancient times but , in spite of popular belief, not by the Vikings. Jürgen Spanuth, the leading proponent of a North Sea Atlantis, has identified the Sea Peoples who attacked the Egyptians as North Sea Peoples. The attack was recorded by the Egyptians on the walls of Medinet Habu and where they depicted some of the invaders with horned helmets. Spanuth claimed that “The only known Bronze Age horned helmets come from north Europe”[0015.55]. The illustrations from the Danish National Museum used by Spanuth[0015.31] were more likely to have been for ceremonial use and show no signs of having been used in battle. A January 2018 article highlights a horned figure on the so-called Oseberg Tapestry, who appears to be leading a religious procession, contributing to the theory that the few horned helmets found so far were probably used for ceremonial purposes(e). Another textile fragment found at the same site also depicts a horned person, which to my mind is more reminiscent of a nordic shaman than a warrior.
>Baruch Halpern in a footnote in his paper(f) on the Sea Peoples informed us that “Sherden-like horned helmets have also been found along the northern shore of the Black Sea and on statuettes in Sardinia, but that these lack the central disks, and may reflect coincidence, appropriation, trade or migration rather than indicate a place of origin. The iconographic connections of the horns and disk would suggest devotion to a lunar god; see Bernett and Keel (1998).”<
Furthermore, he was incorrect in claiming that horned helmets were only used in northern Europe during the Bronze Age. Archaeologist Roger Grosjean (1920-1975) has demonstrated(a) that the Torreans of Corsica did use such helmets during that period. The Sherden/Shardana, considered to be one of the Sea Peoples depicted at Medinet Habu are shown as wearing horned helmets and in every instance, except three, they include a round additional piece on the crest. The Shardana are generally accepted to be from Sardinia and are possibly related to the Torreans on neighbouring Corsica. However, the Sardinian examples do not appear to have the accoutrement at the helmets’ crest depicted at Medinet Habu.
In conclusion, I think Spanuth’s horned helmet evidence is flawed but also that the Sardinian theory is not watertight. Furthermore, his core claim of an invasion from the North Sea into the Eastern Mediterranean is equally untenable. Bronze Age territorial expansion was always into adjacent or nearby territory. A journey of over 4,000 miles from Heligoland to attack Egypt makes no sense.

Giovanni Ugas is an archaeologist at the University of Cagliari, Sardinia, who has written extensively about the Shardana, their name, origin and language(c). The Shardana are usually counted as one of the Sea Peoples.
He has also touched on the subject of Atlantis, describing it as “a fabulous story with a political message, but this does not preclude the existence of a physical and historical substratum on which the myth is built. The task of tracing the shreds of history and geography of this story is fraught with pitfalls.”
He also claims that the Mediterranean coast of southern Spain and France, along with the Italian peninsula was the ‘true continent‘ referred to by Plato (Timaeus 25a).

Eckart Kahlhofer (1936- ) is a German entertainer(a) and Atlantis researcher who has recently added his support to the concept of Atlantis in North-West Europe echoing some of the ideas of Jürgen Spanuth. He identifies the invasions of the Sea Peoples with that of the Atlanteans during the 12th century BC. Like Spanuth he also equates orichalcum with amber. Among his more creative ideas is to identify the Shardana as coming from Sweden and similarly argues that the Philistines came from northwest Europe.
Additionally, he contends that the elephants referred to by Plato were in fact deer, claiming that a scribal error resulted in the Greek word elaphos (deer) being transcribed as elephas (elephant).
He strongly rejects the commonly accepted interpretation of Caphtor, contending that the term refers to the ‘pillar of heaven’ in the North Sea holding up the sky and personified by Atlas.(See: Archive 2809)
Publication of his book, Atlantis in the Third Millennium, was imminent and due to have been available in English and German. However, he has now published an ebook with the title of Mit Atlantis–die andere Dimension (Atlantis: The Other Dimension) in German.
In October 2013, Kahlhofer published an English translation of a sample of his work. His latest book Der Atlantis Codex is now available as a free pdf file(b).
He updated his website(c) and the English translation of Der Atlantis Codex in December 2019.>Further amendments were added in January 2021(d)<

The Philistines are often claimed as having been one of the Sea Peoples described in the Egyptian records and frequently linked with the Peleset, one of the alliance. The idea seems to have originated with Jean-François Champollion, the renowned Egyptologist, who was probably the first to identify the Philistines with the Sea Peoples. His views had general acceptance, but the inevitable dissenting voices have made this is another controversial area for historians and archaeologists to squabble over.
Trude (1922-2016) & Moshe Dothan (1919-1999) in their People of the Sea identify the Philistines as part of the ‘Aegean Sea Peoples’, but with regard to the Shardana, they paint a more complex picture, noting that they were one of the Sea Peoples who settled on the coast of Caanan[p.214]. . However, it seems that they were not only part of the attack on Egypt, but at different times performed as mercenaries[p.213] for the Egyptians!
*In July 2019, a report was published offering DNA evidence that the Philistines had come from Europe(a).*
Even more contentious are the views of Jürgen Spanuth who claimed that what he calls the North Sea Peoples took control of what had been the coastal land of what was to become Lebanon and Palestine and were then known as the Philistines. He claimed that these Philistines later integrated with the Caananites to become the highly successful Phoenicians.
Dr Jürgen Spanuth (1907-1998) was born in Austria and studied theology and archaeology at university. He became pastor of Bordelum in Northern Germany. His first book Das Entraselte Atlantis was published in 1953, following excavations near Heligoland. It was later published in English and is now available to read on the Internet(a). His basic thesis was that following a major catastrophe in the North Sea around 1250 BC, the Mediterranean experienced an invasion of Scandinavians, whom he referred to as the ‘North Sea Peoples’. Part of the physical evidence he produced was the horn-helmeted Sea Peoples depicted at Medinet Habu. Since we are all used to seeing Vikings depicted with horned helmets, many are surprised to find that it is a late 19th-century invention(e)(f).
Spanuth’s theory implies that such helmets had been a standard army issue in the region for over a millennium. In fact the Vikings used rather plain helmets which they did not manufacture themselves but traded for them from other Germanic peoples on mainland Europe(d). On the other hand, one of the Sea Peoples, the Shardana, generally believed to have come from Sardinia, did use horn-helmets. However, there are aspects of this claim that are the subject of continuing debate, but the suggestion of a North Sea connection has weakened considerably.
Spanuth considered Basileia, the royal island of Atlantis, to have been located near Heligoland. He produced a mass of evidence to support his views but found his book under severe attack by many academics, which, in general, had the support of the public. After being publicly labelled, among other things, a liar, Spanuth was forced to challenge his detractors in the courts. After some six years, he was vindicated when ten professors withdrew their plea, admitting that their arguments against the pastor were untenable. Felix R. Paturi has more information[1339.215] on this disgraceful episode, as well as a note of scientists who supported Spanuth.
A study of Spanuth’s references would suggest that he had access to the prehistoric research archives of the Ahnenerbe and has successfully collated and analysed a lot of this extensive material in his books. Vidal-Naquet bluntly labels him a Nazi[580.124], although his publisher, Wolfram Zeller, denied it. It may be relevant to mention that in the 1930s, Heinrich Pudor an avowed German anti-Semite also proposed Helgoland as Atlantis, but I have been unable to find any reference to Pudor by Spanuth!
The German Wikipedia claims that Spanuth was a member of the NSDAP (Nazi Party) from 1933 until 1945. Similar claims that he had been in the SS have also been refuted(c). In 2002, Frank Doenenburg, on his website(b)discussed Spanuth’s politics at length. In my view, all these matters, however unsavoury, risk distracting us today from discussing dispassionately the merits or otherwise of Spanuth’s Atlantis theories.
Spanuth’s second book had a much better reception. His final offering was Die Atlanter(1976), which was also published in English, however, this is really just a revised and expanded version of his 1965 book.
Spanuth has still a lot of supporters and is constantly referred to, particularly by German investigators such as Arn Strohmeyer and Gerhard Herm. Felice Vinci, who strongly favours a Northern European origin for Homer’s epic tales, also places Atlantis in a northern context. The Danish writer, Kirsten Bang, published a short book in which she also placed Atlantis in the Wadden Sea where Helgoland is located. She also supports a date of 1300 BC for its destruction.
Another recent supporter of Spanuth’s Atlantis theory is Holger Kalweit who has written a trilogy, the first of which is Irrstern über Atlantis. This initial volume is concerned with the destruction of Atlantis by a comet (Phaeton) in 1222 BC, leaving Helgoland as a remnant. Refugees fled south to the Eastern Mediterranean leaving their cultural imprint on the region. Unfortunately. this huge 700-page book is to be followed by two more in which the author moves on to expand on the subject of ‘lizard people’, which for me has him as a fully paid-up member of the lunatic fringe.

The Shardana (or Sherden) is usually accepted as another name for one of the groups that comprised the maritime alliance of Sea Peoples. The earliest reference to the Shardana is in the Amarna Letters (1350 BC). However, they are also recorded as mercenaries in the Egyptian army. Since a number of writers have linked the Sea Peoples with the Atlanteans, the Shardana may be legitimately included in any comprehensive search for the truth of the Atlantis story.
The Shardana do appear to have a more complicated history than we are initially led to believe. They are first mentioned in the Amarna Letters (14th century BC.) where they are depicted as part of an Egyptian garrison, after that, some of them were part of the personal guard of Rameses II, later still they are listed as part of the Sea Peoples. A subsequent reference describes them occupying part of Phoenicia.
They are generally identified with the ancient Sardinians, who were the builders of the Nuraghi. Leonardo Melis, a Sardinian, has written extensively on the subject. Links have also been proposed between the Shardana and the lost tribe of Dan and even the Tuatha De Danaan who invaded Ireland.
Trude & Moshe Dothan in their People of the Sea identify the Shardana as part of the ‘Aegean Sea Peoples’, who settled on the coast of Caanan[p.214]. They also note that “There was as well linguistic and archaeological evidence connecting them with the island of Sardinia, where Mycenaean IIIC:1b pottery was found. Sardinia may have been either their original homeland or, more probably, one of their final points of settlement.”
D’Amato & Salimbeti concluded that ” on the basis of the combined evidence from Corsica and Sardinia, it is difficult to conclude with any confidence if the Sherden originated from or later moved to this part of the Mediterranean.” They find the second theory “more reasonable.”[1152.17]
*David Rohl has suggested that the Shardana had originated in Sardis in Anatolia, but “ended up settling in the western Mediterranean, first on the Italian coastal plain west of the Apennines and then in Sardinia – which is, of course, named after them – and Corsica. Their name was clearly pronounced ‘Shardana.'” [229.410]*
DNA testing has shown links between Sardinia and Anatolia in Turkey. The late Philip Coppens also noted that the Sardinians are genetically different to their neighbours on Corsica and the mainland of Europe and suggested an Eastern Mediterranean origin for them.(a)
Giovanni Ugas an archaeologist at the University of Cagliari has written extensively on the subject of the Shardana, who he claims were the builders of the nuraghi. Ugas has also touched on the subject of Atlantis, which he locates in northwest Africa(b), across Morocco, Algeria and Tunisia.
Obviously further research is required to try to establish with greater certainty the exact origins of the Shardana and their links, if any, with Sardinia and/or Atlantis.

Leonardo Melis (1949- ) was born in Sardinia. He has written extensively on the Shardana, one of the Sea Peoples, who are usually accepted as coming from Sardinia. It is to be hoped that Melis’ book will be published in English before long. Melis also links the Shardana with the lost tribe of Dan and also the Tuatha DeDanaan who invaded Ireland in the dim and distant past. Melis continues to have his books supported by a website(a) with an English translation.

Sardinia is an autonomous 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(ar), 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, who lived around 500 years later. 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.
However, in 2000, McMenamin was obliged to confirm that the coins in question were fakes(as) as revealed in his book, Phoenicians, Fakes and Barry Fell .
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 Phoenicians in 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 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.
Angelo Paratico also proposed a connection between the Lydian capital Sardis and Sardinia in a lecture delivered in Hong Kong in 2004(an). Wikipedia includes the following information “According to Timaeus, one of Plato’s dialogues, Sardinia and its people as well, the “Sardonioi” or “Sardianoi”, might have been named after “Sardò”, a legendary woman from Sardis, capital of the ancient Kingdom of Lydia in Anatolia.”(ao)
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’.
The ancient-wisdom.com website, in a well-illustrated aericle, has drawn attention to the fact that the nuraghi, while very numerous are not the only distnct form of megalithic monument on the island, but there are two others known as ‘Tombes Gigantes’ (Giants Tombs) and ‘Domus de Janas’ (Spirit Homes).(ap)
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 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, 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). However, others such as Silvio Diego Novo have followed Frau’s lead(aq), while Aldo Bonincontro has also nominated Sardinia as Atlantis, which he did in a 2007 article, but without any reference to Frau!
In June 2015 Frau together with a 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 sardolog.com 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. The excellent phoenicia.org 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 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 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.
In late 2016, Nicola Betti, Luciano Melis & Alessandro Mugria published Il mare addosso. L’isola che fu Atlantide e poi divenne Sardegna  in which they add their support to the idea of Atlantis in Sardinia. They believe “with reasonable certainty that a large area of south-west Sardinia was hit by a swarm of iron meteorites in a period between 11,000 and 9000 BC,” which would have caused a catastrophic mega-tsunami.(am)
