An A-Z Guide To The Search For Plato's Atlantis


Joining The Dots

Joining The Dots

I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato's own words, tempered with some critical thinking and a modicum of common sense.

Mark Adams


Pythagoras (c570 – c495 BC) was a Greek philosopher and mathematician and probably best known today for the theorm relating to right-angled triangles that is named after him. However, it has been shownpythagoras-statue that it was known at least a thousand years earlier in Egypt, Babylon and China(a).

Although born in Samos he eventually moved to Croton in Magna Graecia, now southern Italy. There, he established a quasi-religious sect of what were

in effect were number worshippers.

Wikipedia notes(c) that “Aristotle claimed that the philosophy of Plato closely followed the teachings of the Pythagoreans, and Cicero repeats this claim: Platonem ferunt didicisse Pythagorea omnia (“They say Plato learned all things Pythagorean”). Bertrand Russell, in his A History of Western Philosophy, contended that the influence of Pythagoras on Plato and others was so great that he should be considered the most influential of all Western philosophers.”

Mark Adams in his Meet Me in Atlantis[1070] has touched on the possible Pythagorean influence on Plato’s use of numbers in his Dialogues. With this in mind, Adams visited the late Ernest G. McClain the author of a highly original idea, namely that details contained in Plato’s Atlantis story can be explained in terms of mathematical/musical theory. This was expressed in his 1978 book, The Pythagorean Plato[1082], which can be read online(b), but, be warned, most will find this very technical offering rather heavy going.

*In 2010, Dr. Jay Kennedy, an American at the University of Manchester, also claimed to have found evidence of Pythagorean influence in Plato’s dialogues claiming that they contain a regular mathematical structure which relates them to an ancient 12-note musical scale. “Kennedy’s breakthrough, published in the journal Apeiron this week, is based on stichometry: the measure of ancient texts by standard line lengths. Kennedy used a computer to restore the most accurate contemporary versions of Plato’s manuscripts to their original form, which would consist of lines of 35 characters, with no spaces or punctuation. What he found was that within a margin of error of just one or two percent, many of Plato’s dialogues had line lengths based on round multiples of twelve hundred.”(e) A critique(f) of Kennedy’s theory by Professor Andrew Gregory of University College London should be read for balance.*

An example of Plato’s regard for specific numbers is his idea that 5,040 is a perfect number and is the ideal population for a polis (city). It is a number divisible by all integers from 1 to 10, which would have had even greater significance prior to the invention of decimals. Some of the other factoids claimed for this number are really scary or at least thought-provoking(d).

Adams, Mark

Mark Adams is an American writer from New York State with the best-selling Turn Right at Machu Picchu[976] to his credit. He Mark-Adams-350x350has spent recent years researching the subject of Atlantis, travelling extensively in the process. One of his trips took him to Ireland where I had the pleasure of meeting him and having many discussions on the subject.

His book, Meet me in Atlantis[1070], gives readers an up-to-date overview of modern Atlantis theories that is both comprehensive and fair. I am aware of the amount of research that Adams has put into this work, interviewing a wide range of individuals, including myself, on both sides of the Atlantic. He has an easy-to-read style and while I do not agree with all of his views, I sincerely believe that this book should be compulsory reading for anyone with a serious interest in the subject.

Following the initial publication of his book Adams gave a number of promotional media interviews and in May 2016, following the publication of the paperback edition, he wrote an article(a) listing three ‘problems’ that he believes should be kept in mind when embarking on a search for Atlantis;

    “1. Every Single Reliable Clue We Have about Atlantis comes from Plato

  1. Plato Was a Pythagorean
  2. Plato Was a Philosopher, not a Historian”

For my part, I do not see these as problems, just matters for consideration rather than concern.



Machu Picchu

Machu Picchu is generally accepted to have been an Incan retreat, built in the middle of the 15th century on a barely accessible mountaintop of Peru about fifty miles northwest of Cuzco. It was apparently abandoned a century later and only brought to the attention of the outside world in 1911, when it was rediscovered by Hiram Bingham.

machu picchu

Mark Adams, the American writer, wrote an account of his retracing of Bingham’s journey to Machu Picchu[976]. Along with the narrative of his pilgrimage, Adams has also interwoven a valuable history of the region.

In 2013, a Polish-Peruvian team, while exploring a previously unexcavated building on the site, claimed to have discovered that the structure was astronomically aligned(a).  The following year saw a newly discovered section of the Inca Road, which leads to Machu Picchu, announced by the Andina News Agency(c).

In July 2016, it was reported that what are considered pre-Inca petroglyphs were discovered in the Machu Picchu region(d)(e). Research is proceeding.

*It was revealed in 2019 that work had commenced on the building of a new interational airport to service Machu Picchu, a development has been vigorously opposed as a threat to the already fragile site. It is worth noting that in 2017, 1.5 million visitors, nearly twice the limit recommended by UNESCO, came to Machu Picchu(g).*

Some pathetic attempts have been made to link Machu Picchu with Atlantis. One of them claims that “This was the (summer?) residence of the continental governor, who at the time of the destruction of Atlantis was a woman.”(b) Others, such as Rand Flem-Ath along with the late Colin Wilson[063], as well as Jim Alison, have included the Andean site in proposed global grids linking prehistoric sites.

A less-known Inca site is that of Choquequirao(f), sometimes referred to as the ‘sister’ of Machu Picchu. Only a third of the site has been excavated so far.










North Africa

North Africa has received considerable attention as a possible location for Atlantis since the beginning of the 19th century. Gattefosse and Butavand are names associated with early 20th century North African theorists. They, along with Borchardt, Herrmann and others have proposed locations as far west as Lixus on the Atlantic coast of Morocco, on through Tunisia and Libya and even as far east as the Nile delta.

One of the earliest writers was Ali Bey El Abbassi who discussed Atlantis and an ancient inland sea in the Sahara. The concept of such an inland sea, usually linked with Lake Tritonis, has persisted with the Chotts of Tunisia and Algeria as prime suspects. There is acceptance that a seismic/tectonic convulsion in the vicinity of the Gulf of Gabés cut off this inland sea from the Mediterranean. Diodorus Siculus records this event in his third book dating it to around 1250 BC. If such an event did not occur, how do we explain the salt laden chotts? However, proving a connection with Atlantis is another matter.

Whether this particular geological upheaval was related to the episode that destroyed parts of ancient Malta is questionable as the Maltese event was one of massive subsidence.

It should be kept in mind that Plato described the southern part of the Atlantean confederation as occupying North Africa as far eastward as Egypt (Tim.25b & Crit.114c). This of course conflicts with the idea of the Atlanteans invading from beyond ‘Pillars of Heracles’ situated at Gibraltar since they apparently already controlled at least part of the Western Mediterranean as far as Italy and Egypt.

*One of the principal arguments against Atlantis being located in North Africa is that Plato clearly referred to Atlantis as an island. However, as Papamarinopoulos has pointed out that regarding the Greek word for island, ‘nesos’ “a literary differentiation between ‘island’ and ‘peninsula’ did not exist in alphabetic Greek before Herodotus’ in the 5th century BC. Similarly, there was not any distinction between a coast and an island in Egyptian writing systems, up to the 5th century BC.” In conversation with Mark Adams[1070.198] Papamarinopoulos explains that in the sixth century BC, when Solon lived, nesos had five geographic meanings. “One, an island as we know it. Two, a promontory. Three, a peninsula. Four, a coast. Five, a land within a continent, surrounded by lakes, rivers or springs.”

Personally, from the context, I am quite happy to accept that the principal city of the Atlantean alliance existed on an island as we understand the word. This was probably north of Tunisia, where a number of possible candidates exist. However, it may be unwise to rule out a North African city just yet!

Another argument put forward that appears to exclude at least part of North Africa is that Plato, according to many translations, he refers to Atlantis as ‘greater’ than ‘Libya’ and ‘Asiacombined, using the Greek word, ‘meizon‘, which had a primary meaning of ‘more powerful’ not greater in size. Atlantis could not have been situated in either Libya or Asia because ‘a part cannot be greater than the whole’. However, if Plato was referring to military might rather than geographical extent, as seems quite likely, North Africa may indeed have been part of the Atlantean alliance, particularly as Plato describes the control of Atlantis in the Mediterranean as far Tyrrhenia and Egypt.*


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 *eastward* 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.

Papamarinopoulos, Stavros

Stavros Papamarinopoulos is Professor of Applied Geophysics at the University of Patras in Greece. In 2003 he led a team from his university in an attempt to locate the tomb of Alexander the Great in the cemetery quarter of Alexandria.

papamarinopoulos2Papamarinopoulos was one of the organisers of the Atlantis Conferences of 2005[629], 2008[750] and 2011. He was also the editor of the published proceedings of those conference. Furthermore, he delivered a number of papers to all three conferences.

*Mark Adams, author of Meet Me in Atlantis[1070] describes Papamarinopoulos as “the world’s most respected Atlantis expert”(h).*

In his paper A Bronze Age Catastrophe in the Atlantic Ocean?, he points out some of the pitfalls associated with the interpretation of prehistoric events when using the language of 4th century B.C. “For instance, a literary differentiation between ‘island’ and ‘peninsula’ did not exist  in alphabetic Greek before Herodotus’ in the 5th century B.C. Similarly, there was not any distinction between a coast and an island in Egyptian writing systems, up to the 5th century B.C.” Papamarinopoulos maintains that a lack of knowledge of such linguistic shortcomings has been used unwittingly by many who deny the existence of Atlantis.

Papamarinopoulos personally supports the idea of an Iberian Atlantis(f)(g). He presented this view in a series of six papers(b)presented to a 2010 International Geological Congress in Patras, Greece. Papamarinpoulos has written a number of other papers including one which discusses Phaeton as a comet and its possible coincidence with the Trojan War(a).

Papamarinopoulos is also co-author with John S. Kopper of a paper(c) which concluded that  there is “a strong correlation between times of abrupt physical and cultural changes in man and reversals of the earth’s magnetic field.”

In 2012 Papamarinopoulos et. al published a paper(d)(e) that carefully analyses astronomical data enabling them to conclude that a solar eclipse of 30th October 1207 BC occurred just five days after Homer’s Odysseus returned to Ithaca.

Island, Peninsula or Continent?

Island, Peninsula or ContinentAdvocates of a continental rather than island identification for Atlantis have to contend with the fact that Plato never referred to Atlantis as a continent instead he used the Greek words for island, namely ‘nesos’ and ‘neson’. Their line of argument is that these words in addition to ‘island’ or ‘islands’ can also mean “islands of an archipelago” or “peninsula”. Furthermore it is claimed that the ancient Greeks had no precise word for ‘peninsula’.

Gilles le Noan[912], quoted by Papamarinopoulos[629.558], has offered evidence that there was no differentiation in Greek between ‘island’ and ‘peninsula’ until the time of Herodotus in the 5th century BC. In conversation with Mark Adams[1070.198] he explains that in the sixth century BC, when Solon lived, nesos had five geographic meanings. “One, an island as we know it. Two, a promontory. Three, a peninsula. Four, a coast. Five, a land within a continent, surrounded by lakes, rivers or springs.”

   Robert Bittlestone, in his Odysseus Unbound [1402.143] also notes that “nesos usually means an island whereas cheronesos means a peninsula, but Homer could not have used cheronesos when referring to the peninsula of Argostoli for two very good reasons. First, it cannot be fitted into the metre of the epic verse and second, the word hadn’t yet been invented: it doesn’t occur in Greek literature until the 5th century BC.”

Another researcher, Roger Coghill, echoed the views of many when he wrote on an old webpage that “To the Greeks peninsulae were the same as islands, so the Peloponnesian peninsula was “the island of Pelops” and the Chersonnese was to them “the island of Cherson”. Similarly in describing a place found after escaping the Pillars of Hercules, Plato quite normally describes the Lusitanian coast (modern Portugal) as an “island”, reached, he clearly says, after passing Cadiz”.

Johann Saltzman claimed that ‘nesos’ did not mean ‘island’ or ‘peninsula’ but ‘land close to water’. However I would be happier sticking to the respected Liddell & Scott’s interpretation of island or peninsula. If Saltzman is correct, what word did the Greeks use for island?

The Modern Greek word for peninsula is ‘chersonesos’ which is derived from ‘khersos’ (dry) and ‘nesos’ (island) and can be seen as a reasonable description of a peninsula. It is worth noting that the etymology of the English word ‘peninsula’ is from the Latin ’paene’ (almost) and ’insula’ (an island).

Jonas Bergman maintains that the Greek concept of ‘island’ is one of detachment or isolation. He also points out that the original Egyptian word for island can also mean lowland or coastland, because the Egyptians had a different conception of ’island’ to either the ancient Greeks or us. Some commentators have claimed that the Egyptians of Solon’s time described any foreign land as an island.

Eberhard Zangger offers another correction of the Atlantis mystery: If one compares the land- / sea-distribution in Egypt and in the Aegean Sea, it becomes obvious why the Egyptians used at that time the expression “from the islands”. While today the word “island” has a clear meaning, this was not the case at the late Bronze Age. For the Egyptians more or less all strangers came from the islands. As there had been practically no islands in Egypt, the ancient Egyptian language did not have any special character for it. The hieroglyphic used for “island” was also meaning “sandy beach” or “coast” and was generally used for “foreign countries” or “regions on the other side of the Nile”.

A contributor to the Skeptic’s Dictionary(b) has added “I remind you that the Greek definition of “island” paralleled that of “continent.” To the Greeks, Europe was a continent. West Africa was an island, especially since it was cut off from the rest of what we now call “Africa” by a river that ran south from the Atlas mountains and then west to what is now the Western Sahara. This now dry river was explored by Byron Khun de Prorok in the 1920’s.”

Reginald Fessenden wrote: “One Greek term must be mentioned because it has given rise to much confusion. The word ‘Nesos’ is still translated as meaning ‘island’ but it does not mean this at all, except perhaps in late Greek. The Peloponnesus is a peninsula. Arabia was called a “nesos” and so was Mesopotamia”. This ambiguity in the written Greek and Egyptian of that period was highlighted at the 2005 Atlantis Conference by Stavros Papamarinopoulos.

Werner Wickboldt pointed out at the same conference that Adolph Schulten in the 1920’s referred to a number of classical writers who used the term ‘nesos’ in connection with the Nile, Tiber, Indus and Tartessos, all of which possessed deltas with extensive networks of islands.

To confuse matters even further, there have been a number of theories based on the idea that the ‘island’ of Atlantis was in fact land surrounded by rivers rather than the sea. These include Mesopotamia in Argentina proposed by Doug Fisher, the Island of Meroë in Sudan suggested by Thérêse Ghembaza and a large piece of land bound by the Mississippi, Ohio, Potomac rivers offered by Henriette Mertz. However, none of these locations match Plato’s description of Atlantis as a maritime trading nation with a naval fleet of 1200 ships, nor do any of them explain how they controlled the Mediterranean as far as Egypt and Tyrrhenia.

The waters around Plato’s island are indeed muddy!
