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.

The Sea Peoples is the name given by modern scholarship to a group of allies who caused havoc among the nations of the Eastern Mediterranean including Egypt which they invaded at least twice in the 2nd millennium BC. The phrase ‘Sea Peoples’ was never used in any ancient accounts. The coining of the term in 1855 is now generally attributed to French Egyptologist, Emmanuel de Rougé who used the term peuples de la mer (literally “peoples of the sea”) in a description of reliefs at Medinet Habu. The phrase was later popularised by another French Egyptologist, Gaston Maspero (1846-1916). Eckart Kahlhofer has recently suggested that even earlier, J. F. Champollion (1790 –1832) employed an equivalent term gens navales to describe the occupants of the invading swan-necked boats. Just a few years after Maspero the German classical scholar, Wilhelm Christ, was probably the first to identify the invading Sea Peoples with the Atlanteans(p), predating Jürgen Spanuth’s theory by the better part of a century. Christ’s idea was also supported to varying degrees by Theodor Gomperz, Spyridon Marinatos, John V. Luce, Herwig Görgemanns and Ulrich Hofmann.
Cyprian Broodbank in The Making of the Middle Sea  argues that the Sea People “never actually existed as a single people. Instead small roving bands were a symptom of the collapse, not the cause, and they were blown out of proportion by Egyptian propagandists working for Ramasses III.” (ai)
The Sea Peoples’ exact origin continues to be a matter of intense speculation(ad). The debate regarding their true identity has been ongoing for a long time and will probably continue as long as the chronologies of the Middle East are not fully harmonised to the satisfaction of all. There is some agreement that the Sea Peoples mounted two separate invasion attempts on Egypt around 1208 & 1176 BC (Facchetti & Negri).
There is a claim that the Sea Peoples also attacked Mycenaean Greece on two occasions and that Athens survived both(ae). Contrast that with the contention that there was a Mycenaean group within the Sea Peoples. The confusion surrounding the Sea Peoples is exemplified by the response to a question on the quora.com website(af).
The earliest book devoted to the Sea Peoples, that I am aware of, was Immanuel Velikovsky’s Peoples of the Sea. However, Velikovsky was more concerned with revising the chronologies of the Middle East and so focused on dating the invasion of the Sea Peoples rather than identifying their origins.
The Oxford Companion to the Bible is certain that the Sea Peoples were originally Mycenaean, who moved south, following the collapse of their civilisation at the end of the Late Bronze Age. They were repelled by the Egyptians and then moved on to the Levant where they later became known as the Philistines. A paper(ab) that also links the Philistines with the Sea Peoples from a biblical perspective is available.
A more recent (2017) paper(aa) on a conservative website suggests that the Sea Peoples were ‘early Western Europeans’.
One website(h) describes the Sea People as groups of dispossessed raiders driven by hunger following crop failures resulting from climate change. The same idea is expanded on by Lu Paradise in an extensive article(v). In an April 2020 article by Mark Woolmer he notes(aq) that the ‘Amarna Letters’ “record that two groups of pirates, the Lukka and Sherden, were causing substantial disruption to regional commerce and security.” Woolmer also notes the ambiguous attitude to piracy at that period.
A different view was expressed by the Egyptologist Robert Anderson who commented “It would seem that, rather than bands of plunderers, the Sea People were probably part of a great migration of displaced people. The migration was most likely the result of widespread crop failures and famine.”(d)
Evidence is mounting that climate change played a significant part in the Late Bronze Age collapse of civilisations in the Eastern Mediterranean region. In fact there is a school of thought that believes that the widespread societal disintegration was more the result of environmental factors rather than the depredations of the Sea Peoples(ag).
The Malagabay website published a lengthy article(t) in July 2016, offering evidence along with some conjecture, supporting the radical idea that the Sea Peoples had originated in India and having migrated westward, some of them reached the Aegean and became known as Dorians! The author of the article appears to have followed the ideas of Edward Pococke published in his India in Greece.
Bob Idjennaden along with co-author, Mebarek S. Taklit, have produced The Mysterious Sea Peoples attack Egypt, which provides an overview of the various incursions against Egypt during the 2nd millennium BC. The prominent part played by the Berbers in varying alliances that constituted the Sea Peoples is highlighted.
Eberhard Zangger argues that the Sea Peoples were survivors of the Trojan War that fled to various parts of both central and eastern Mediterranean(g). He has written further on this identification and more on the Luwian Studies website(s). Zangger claims that the Sea Peoples were an alliance of Libyans and Western Anatolian (Luwian) states(s)(y), which seems odd since Plato describes the Atlanteans as mightier than Libya and Asia combined. If Zangger is correct in identifying Troy as Atlantis, he is also implying that a part (Troy) is greater than the whole (Libya and Asia combined), Troy being part of Asia! Something is clearly wrong with his theory.
Jürgen Spanuth,not surprisingly, referred to them as the North Sea Peoplesand offered a range of evidence from Egyptian inscriptions at Medinet Habu to support this idea. This evidence includes a variety of features that Egyptians used to portray the Sea Peoples such as types of swords, shape of ships, shields and helmets as well as hair, clothing and shaving fashions. He then identified these Scandinavians as Atlanteans who later attacked Egypt. His opinion in this regard was strongly supported by Felix R. Paturi[1339.218]. Quite recently Spanuth’s ideas have also been echoed by Walter Baucum in his Bronze Age Atlantis.
Prior to the development of these Bronze Age seafarers there was a history of Northern Boat-peoples who gradually expanded globally after the last Ice Age. A paper by Andres Pääbo charts their story(k). Zach Zorich is a freelance journalist and contributing editor at Archaeology magazine. In January 2016 he wrote an article(r) that would seem to contradict the idea of Northern European ‘Sea People’ invading Egypt, for the simple reason that sailing boats were not developed in Scandinavia until around the time of the Vikings! – “The plankboats and logboats being built in northern Europe were not the most advanced watercraft of their time. The Greeks, Egyptians, and other cultures around the Mediterranean Sea used sailing ships to conduct trade, and sails wouldn’t be used in Northern Europe until the Iron Age, during the seventh or eighth century CE.”
Quite a number of writers have identified the Atlanteans as the Sea Peoples whose invasion of the Eastern Mediterranean has been recorded in some detail by the Egyptians. One such high profile identification in the 20th century was by Spyridon Marinatos.
One of the latest to join this school is Dr. Rainer W. Kühne,who not only makes the same identification, but using satellite images, he believes that he has pinpointed the capital of Atlantis in Southern Spain. His website has a list of comparisons of Atlanteans and Sea Peoples(a) which is worth consideration.
Erick Wright, a regular contributor to Atlantis Rising forums, has now concluded(b) that Atlantis was located in modern southern Turkey and that Atlanteans were among the Sea Peoples who attacked Egypt in 1200 BC.
Another Atlantis Rising forum(e)on the subject is also worth a look as is another illustrated site(f) which includes a map of the homelands of the Sea People.
According to Raffaele D’Amato & Andrea Salimbeti [1152.20], the Denyen were one of the major groups of the Sea Peoples and have been known in ancient sources by different names; Danai, Danaoi, Danaus, Danaids, Dene, Danaids, Danuna. Other have linked them with the Danaan of Irish mythology. Velikovsky has an interesting footnote in his Peoples of the Sea [758.4], which reads; “When Ramses III speaks of ‘Peoples of the Sea’ he specifies the Tkeker, the Shekelesh, the Teresh, the Weshesh and the Sherden (or Sardan) ; he specifies the Denyen as ‘Peoples of the Isles.'”
In his book, The Luwian Civilisation [1217.20], Zangger makes the interesting point that “Sea Peoples with feather crowns bear the name Tekker, which is reminiscent of ‘Teucer’, a term commonly used for the Trojans after 1200 BCE.”
The Tuatha de Danaan invaded Ireland in prehistoric times. Having noted that Dan/Don/Danu were ancient words for water, it is not such a wild supposition that the Tuatha de Danaan were at least a constituent part of the Sea Peoples, an idea promoted by Leonardo Melis. On the other hand Egerton Sykes was of the opinion that the Tuatha de Danaan were refugees from Atlantis, an idea he expressed in his 1949 edition of Ignatius Donnelly’s Atlantis. He was convinced that Murias one of the legendary cities of the de Danann had been located in Bimini. This is highly speculative idea has failed to bear fruit as have all efforts to identify the location of the other three cities, Falias, Finias and Gorias.
Eric Cline has noted that the only member of the Sea Peoples alliance whose identity has been ‘firmly established’ is that of the Peleset who are accepted as Philistines. He also comments that identifying the Shekelesh with Sicily and the Shardana with Sardinia is based in part on the ‘consonantal similarities’[p.4]. In a separate paper he suggests that “the chaos and destructions wrought by the Sea Peoples may have created a power vacuum which allowed the Israelites to take over the land of Canaan.”
Joseph Morris in his thesis(m) presented to the Classics Department of Florida State University in 2006 defined the Sea Peoples as “a coalition consisting of the indigenous populations of Syria-Palestine led by the neo-Hittite states.”
Federico Bardanzellu offers a number of papers on his Museo dei Dolmen website(n) in which he suggests specific homelands for many of the members of the alliance(o).
Another unexpected twist is the claim, by the discoverer of the Phaistos Disk, Luigi Pernier, that the characters used on the Disk are similar to the representations of the Sea Peoples at Medinet Habu.
Also related to the carvings at Medinet Habu is an interesting study of the Sea Peoples’ ships depicted there, by the nautical archaeologist Professor Shelley Wachsmann(aj), who also offers evidence that at least some Mycenaeans were involved with the Sea Peoples(ak). Salimbetti’s website has a lengthy paper on Aegean Bronze Age ships(al) as well as the Sea Peoples(am) .
Another site(an) also describes the various ships of the period used by the Egyptians, Greeks and the Sea Peoples. One unusual suggestion on the same site is that some of the Sea Peoples, although allied with groups from across the Mediterranean, came from Britain and Northern Europe(ao)!
The most radical suggestion regarding the Sea Peoples has come from Jim Allen who has drawn attention to the similarity of their headgear with that of Amazonian ‘Indians’(c).
Speculation regarding the identity of individual tribes in the federation can be found on a number of websites(i)(j). One of the most comprehensive is provided by two Italians military historians, D’Amato & Salimbeti in a 2015 booklet and on the internet(l) and both are to be highly recommended. They highlight the complexities involved in definitively identifying the members of the varying alliances that were loosely described as the ‘Sea Peoples’ over a three hundred year period.
Trude & Moshe Dothan have added another valuable book to the Sea Peoples literature with their People of the Sea, which has the interesting sub-title of The Search for the Philistines. Related to their work, is the result of recent excavations at Ashkelon, an important Philistine city, which suggests that the city had received migrants from southern Europe during the Bronze Age, who may have constituted a component of the Sea Peoples(ah). Clearly further investigation wll be required to confirm these indications.
An extensive review of all the available material relating to the Sea Peoples was also published online in October 2015(q). The MalagaBay website has also a wide-ranging illustrated article(u) about the Sea Peoples, although without reaching any firm conclusions.
The most recent addition to our knowledge of the Sea Peoples appears to be imminent with the publication of a paper in the December 2017 issue of the journal Proceedings of the Dutch Archaeological and Historical Society. Written by Frederik Woudhuizen and Eberhard Zangger, the authors offer a translation of a 3200-year-old inscription That may refer to the Sea Peoples and linking them with western Turkey. You can read more, now, on the Livescience website(z) . In a 2006 paper(ac), The Ethnicity of the Sea Peoples, Woudhuizen included some groups from the Central Mediterranean as part of the Sea Peoples.>Woudhuizen added further commentary in a 2015 paper entitled The Sea Peoples: superior on land and at the sea(at).<
There is an extensive bibliography of books and papers relating to the ‘Philistines and other Sea Peoples’ available online (last updated 16.09.19)(ap). In addition there is a comprehensive compilation of all primary sources of references to the Sea Peoples and its constituent members also available(ar).

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)
