Sweden was claimed to be the location of Atlantis by Olaus (Olaf) Rudbeck in the 17th century. Before him another Swede, Johannes Bureus, expressed similar views. His friend Carl Lundius supported Rudbeck’s theories, but received none of the acclaim.
In the 18th century Carl Friedrich Baër was happy to follow a fashion, which placed Atlantis in the Holy Land. I am not aware of any major Swedish contribution to Atlantology in the 19th century.*However, the following century saw a number of Swedish researchers make valuable contributions to the subject.*
The discovery of the Mid Atlantic Ridge led René Malaise and Hans Pettersson to suggest the Azores as remnants of Atlantis, an idea still popular today. Around the same time Gunnar Rudberg proposed that Syracuse in Sicily had inspired some of Plato’s description of Atlantis. Arvid Högbom advocated the North Sea as the location of Atlantis in 1915, long before Jürgen Spanuth. In the same region Nils Bergquist opted for the Dogger Bank as has Ulf Erlingsson.
More recently, we seem to have come full circle as Bertil Falk has revived some of Rudbeck’s ideas(a) and a short illustrated 2007 paper (updated 2015)(b) by Robert Fritzius also added some additional modern support. However, for something quite different we have Carl Festin promoting a Mediterranean location.
*Nils-Axel Mörner and Bob Lind, two controversial researchers, have proposed, in a number of papers, that a Bronze Age trading centre existed in southeast Sweden, which had links with the Mycenaeans, Minoans and Phoenicians in the Mediterranean. They suggest that ancient references to Hyperborea may have been generated by this trade. However, although they do not associate Hyperborea with the story of Atlantis, they delivered their theories in papers presented to the Atlantis Conferences of 2008 [750.685] and 2011(c). They also touch on a number of other peripheral subjects including Cygnus, archaeoastronomy and amber. Similar views on early Baltic trade with the Mediterranean have been expressed elsewhere(d).*
Dr Nicola Russo was chairman of the Italian Atlantis Society of Bari and was also editor of and contributor to its journal Atlantide in Italia while it was issued between 1930 and 1932.>It was revived briefly again in 1958. Russo also contributed to Lewis Spence‘s Atlantis Quarterly in the 1930s.<
In 1976, Jürgen Spanuth pointed out [0015.249] that the Azores were not the mountain peaks of a sunken continent but instead are composed of volcanic rock created through eruption. He quotes similar sentiments expressed by Hans Pettersson.
>Among Russo’s other unconventional ideas is the view that “the Phoenician alphabet was derived from the Atlantean alphabet, which was taught to the Maya of Central America”!!(a)
The Azores (Açores) is a group of Portuguese islands in the Atlantic, situated 1,500 km from the mainland. The first recorded instance of their discovery is in 1427 by the Portuguese, although there is some evidence to suggest that the Norse reached the islands 700 years earlier(z). However, they were not the first as recent discoveries have shown clearly that megalith builders and others had occupied the archipelago’s island of Terceira long enough to construct a number of megalithic monuments(aa). Professor Felix Rodrigues has claimed that these structures were stylistically related to European megaliths. The island also has a number of cart ruts, a subject about which Rodrigues et al have published a paper(ad). The significance of the megaliths on Terceira is far greater than might be first thought. Received wisdom has it that apart from coastal hugging, ocean-going vessels were not available until the time of the Phoenicians. The Azorean megaliths suggest otherwise. Furthermore, it throws new light on the possibility of Neolithic and/or Bronze Age visits to America from the Old World. A BBC video(ab) has some interesting images, while for Portuguese speakers a RTP video(ac) has an interview with Professor Rodrigues, who has also written a paper on early Atlantic navigation(ae).
The earliest association of the Azores with Atlantis dates from 1499 when Maximillian I of the Holy Roman Empire (1459-1519) appointed Lukas Fugger vom Reh as the ‘titular’ king of Atlantis. The certificate of appointment nominated the Azores as the remnants of Atlantis. Markus Fugger a descendant of Lukas has published a 2013 paper defending this identification of the Azores with Atlantis(x).
In 2012, the president of the Portuguese Association of Archeological Research (APIA), Nuno Ribeiro, revealed(c) that rock art had been found on the island of Terceira, supporting his belief that human occupation of the Azores predates the arrival of the Portuguese by many thousands of years. A further article(a) in October 2016 expanded on this matter. Ribeiro’s research was trotted out in a more recent documentary from Amazon Prime with the tabloid title of New Atlantis Documentary – Proof that Left Historians Speechless(u), which explores the claim that the Azores are the mountain tops of sunken Atlantis!
However, the Portuguese authorities set up a commission to look into Ribeiro’s contentions and concluded(q) that any perceived remnants of an ancient civilization were either natural rock formations or structures of more modern origin. Nevertheless, as the Epoch Times reports(r) that “Antonieta Costa, a post-doctoral student at the University of Porto in Portugal, remained unconvinced and continued research into the hypothesis that the Azores were inhabited in antiquity and even in prehistory.” In 2013, Costa, published, in English, The Mound of Stones  about the megaliths of the Azores.
It seems to me that the research of Rodrigues, Ribeiro and Costa should be looked at again as a combined study so that the ancient history of the Azores can be more clearly understood and its mysteries resolved.
It is thought that the Phoenicians and Etruscans competed for control of the Azores in later years. In 2011, APIA archaeologists reported that they had discovered on Terceira island, a significant number of fourth-century BC Carthaginian temples. They believe the temples were dedicated to the ancient Phoenician/Carthaginian goddess Tanit(c). The Jesuit, Athanasius Kircher, in his 1665 book Mundus Subterraneus, was the first to propose that these islands were the mountain peaks of sunken Atlantis. This view was adopted by Ignatius Donnelly and developed by successive writers and is still supported by many today. The latest recruit is Carl Martin, who is currently working on a book locating Atlantis in the Azores and destroyed around 9620 BC. The late Christian O’Brien was a long-time proponent of the Atlantis in Azores theory. A bathymetric study of the area suggested to O’Brien that the archipelago had been a mid-Atlantic island 480 x 720 km before the end of the last Ice Age. Apart from the inundation caused by the melting of the glaciers, he found evidence that seismic activity caused the southern part of this island to sink to a greater degree than the north. O’Brien pointed out that six areas of hot spring fields (associated with volcanic disturbances) are known in the mid-Atlantic ridge area, and four of them lie in the Kane-Atlantis area close to the Azores.
Klaus Aschenbrenner was originally happy to consider the Azores as a possible location for Atlantis, but further research led him to conclude that this was unlikely(ag).
In 1982 Peter Warlow suggested  that a sea-level drop of 200 metres would have created an island as large as England and Wales with the present islands of the Azores as its mountains. However, Rodney Castleden contradicts that idea[225.187] saying that if the sea level was lowered by 200m “the Azores would remain separate islands.” Bathymetric maps of the archipelago, above and on the Internet(g), verify Castleden’s contention. This together with a 1982 paper from P.J.C. Ryall et al, demonstrates more clearly that the Azores are just the summits of volcanic seamounts that rise from an underwater plateau that is 1000 metres below sea level. Professor Ryall and his associates were dealing objectively with the geology of the area and were not promoting any view regarding Atlantis. The geological evidence supporting an Azorean Atlantis is therefore very weak, verging on non-existent.
Andrew Collins, the leading proponent of a Cuban Atlantis, has written a short review of the Azorean Hypothesis(h).
Frank Joseph has offered his views on Atlantis in the Azores in a YouTube video(l).
Nikolai Zhirov recounts in his book[458.363] how Réne Malaise wrote to him regarding a Danish engineer named Frandsen who identified a plateau, 2/3rds the size of Finland, south of the Azores, whose summits were 4,000-5,000m metres higher than it. Adding canals gave Frandsen a configuration that closely matched Plato’s description of Atlantis. Zhirov also noted[p403] that in 1957 a journal entitled Atlantida was published in the Azores.
In 1976, Jürgen Spanuth pointed out[015.249] that the Azores are not the mountain peaks of a sunken continent but are instead volcanic rock created through an eruption. He quotes similar sentiments expressed by Hans Pettersson. A 2003 paper(b) by four French scientists demonstrated that the Azores had been greatly enlarged during the last Ice Age. However, showing that the Azores were more extensive is not disputed, but it in no way demonstrates that it was the location of Atlantis. In fact, Plato’s description of the magnificent mountains to the north and the mud shoals that were still a hazard in Plato’s day do not match the Azores. The geologist, Darby South, strongly denied that the Azores could have been the location of Atlantis according to a couple of articles posted on the internet some years ago(a). However, natives of the archipelago are quite happy to assert a link with Atlantis, as travel writer David Yeadon found on a visit there(d).
Nevertheless, advocates of Atlantis in the Azores must accept that when the Portuguese arrived on the island in the 15th century they were found to be uninhabited and without any evidence of an earlier advanced civilisation there, such as described by Plato. Initially, the only hint of earlier visitors was some 3rd-century BC coins from Carthage discovered on the island of Corvo. However, in recent years Bronze Age rock art(f) and what is described as a Carthaginian temple(e) have both been discovered on the island of Terceira.
Otto Muck among others was certain that the enlarged Azores had deflected the Gulf Stream during the Ice Age, contributing to the extent of the Western European glaciation. However, a 2016 report(m) from the Center for Arctic Gas Hydrate, Climate and Environment (CAGE) offered evidence that the Gulf Stream was not interrupted during the last Ice Age, which would seem to undermine one of Muck’s principal claims.
Nevertheless, it is still far from clear what caused the ending of the last Ice Age. A number of writers including Muck speculated that an asteroidal impact in the Atlantic was responsible. When the Azores were discovered in the 15th century they were uninhabited and without any evidence of an earlier civilisation. It can be reasonably argued that since the Azores today are just the mountain peaks of a larger mainly submerged island, any remains would be more likely to be found on the plains and estuaries that are now underwater. One undeveloped theory is that the name ‘Azores’ might be linked to the ninth king of Atlantis, Azaes, listed by Plato. This idea is supported by the linguist Dr Vamos-Toth Bator. However, a Portuguese correspondent has pointed out that the Azores is named after a goshawk (Accipiter gentilis) commonly found on the islands and portrayed on the regional flag. The renowned writer, Dennis Wheatley, used the possibility of Atlantis being located in the Azores as a backdrop to his 1936 thriller, They Found Atlantis.
In August 2013 Portuguese American Journal reported that the many pyramidal structures on Pico are clear evidence of extensive human activity in the archipelago long before the arrival of the Portuguese(o). A YouTube video(p) offers some interesting views of the pyramids.>If these pyramid builders were capable of sailing from mainland Europe as far as the Azores, understandably, it has prompted some to question whether the same people were able to complete the journey to the Americas! In 2014, Dominique Görlitz gave a lecture on the pyramids(ai) and the Atlantisforschung website has an article on the debate between Nuno Ribeiro and Portuguese archaeologists regarding the authenticity of the pyramids(aj).<
The following month the same journal announced the discovery of a pyramidal structure 60 metres high at a depth of 40 metres off the coast of the Azorean island of Terceira(i). Shortly afterwards the Portuguese Navy denied the existence of any such structure(j). Not exactly a surprise! Nevertheless, an Italian website has attempted to breathe new life into the story by linking this underwater pyramid report with pyramidal structures found on the island of Pico(k).
Atlantisforschung published an article that included critical comments about the ‘pyramid’ from both Greg Little and Andrew Collins.“A Portuguese Navy commander states that there is a read error of the sonar data and that the alleged pyramid was a volcanic mound. Afterwards, the Portuguese Hydrographic Institute [also] stated that the “ Pyramid ” was a known volcanic mound and posted actual underwater bottom contours of the site obtained from a hydrographic survey.
For the Portuguese Navy and its officials (who were originally said to be excited and involved), that was the end of the matter. But allegations arose almost immediately that this was a cover-up. Apparently, there was a Pyramid of Atlantis there, some claimed, and for obscure reasons, the government didn’t want anyone to know about it. At least that’s what is claimed. But of course, none of the people claiming a cover-up will ever go there and dive or lower a camera themselves. It’s probably [from their point of view; much better to keep it alive as a mystery. At the end of the day, no one wants to admit the truth — or know the truth.”(z).
The Wikiversity website has an extensive article(s) on the location of Atlantis, which is focused on the Azores and the bathymetric evidence for that archipelago having been a large single landmass at the end of the last Ice Age when sea levels were much lower. However, it is based on the literal acceptance of Plato’s 9,000 years before Solon for the date of the Atlantean War.
April 2018, saw British tabloid interest in Atlantis revived with further speculation on the Azores as the location of Plato’s submerged island(t). However, the details of the claim were rejected by Dr Richard Waller a lecturer at Keele University. Not content with recycling the old Azores theory, The Star also throws in the even more nonsensical idea of an Antarctican Atlantis.
A paper by Gerard Janssen of Leiden University places Homer’s Ogygia in the Azores(v).
In 2019, Fehmi Krasniqi published a three-and-a-half-hour video on the building of the Egyptian pyramids. For Krasniqi, the Ancient Black Egyptians travelled to the Americas and many other parts of the world(af). He claims that these ancient Egyptians travelled to America using Atlantis, now the Azores as a stepping-stone. This is offered as an explanation for the huge Olmec stone heads with African features!
A recent (2021) advocate of Atlantis in the region of the Azores is Victor Staner(w). In the same year, I was made aware of the work of Matthew Chinn who also pinpointed a location (38° 32′ 06″ N, 29° 24′ 09″ W) in the Azores region as the site of Atlantis, using satellite imagery and bathymetric data.
My leading questions regarding the proposed Azorean location for Atlantis are (a) why and (b) how would Atlanteans situated in the middle of the Atlantic launch an attack on Athens or Egypt that were over 4,200 km away? Unless those two questions are satisfactorily answered the Azores fails as the home of Atlantis.

Professor Hans Pettersson (1888-1966), was a renowned Swedish scientist, who became the first full professor of oceanography in Sweden and in 1938 founded the Institute of Oceanography in Gothenburg.
Thorwald C. Franke has written a short paper(b) on Pettersson’s important contribution to the Atlantis debates, offering scientific reasons for dismissing the idea of Atlantis being located in the Atlantic. In the process he refuted the earlier theories of Pierre Termier and demolished the idea of transatlantic land bridges.
Although he has excluded the Atlantic, he is equally unhappy with a Mediterranean location, preferring not to accept the Atlantis story as history!
He published his views, in Swedish, in 1944 as Atlantis och Atlanten, which was subsequently translated into German by another physicist, Stefan Meyer, entitled Atlantis und Atlantik.
>An article on the Atlantisforschung website by Ferdinand Speidel offers a totally different view of Petterson’s Atlantis ‘scepticism’(c).<
Pettersson led the Swedish Albatross Expedition of 1947-1948 which surveyed the Atlantic. He subsequently spoke of finding evidence of “great catastrophes that have altered the face of the Earth”(a)
