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.

Tuttle, Robert J.

Robert J. Tuttle (1935- ) is an American nuclear engineer and the author of The Fourth Source: Effects of Tuttle, R.J.Natural Nuclear Reactors[1148], which is a ground-breaking review of “how the effects of nature’s own nuclear reactors have shaped the Earth, the Solar System, the Universe, and the history of life as we know it.”


This large volume (580 pages) challenges many accepted theories, such as glaciation, evolution, and mass extinctions and offers new ideas that will undoubtedly raise eyebrows(a).*The first 25 pages can be downloaded as a free pdf file.*

Surprisingly, Tuttle also tackles the question of Atlantis (p.301) suggesting the possibility that when sea levels were lower, the Balearic Islands in the Western Mediterranean were more extensive and possibly the home of Atlantis. He takes issue with Bury and Lee who refer to the ‘Atlantic Ocean’, which he claims should read as the ‘Sea of Atlantis’ and locates the ‘Pillars of  Herakles’ somewhere between Tunisia, Sicily and the toe of Italy.


Krystek, Lee

Lee Krystek is on the staff of The College of New Jersey and is also the owner of the ‘unmuseum’ website(a).lee-Krystek His site includes a section on Atlantis(b) which is fair and objective.

Krystek is not convinced by Donnelly’s Atlantic location and seems to think that the Minoan Hypothesis is the best theory current available, noting that “Not everyone accepts the Minoan Crete theory of the story of Atlantis, but until a convincing case can be made for some other place, it, perhaps, remains science’s best guess.”

As if hedging his bets, he concludes(c) his Atlantis comments with a link to Robert Ishoy’s Sardinian theory!




Yefremov, I. A.

YefremovI. A. Yefremov (1908-1972) was a well-known Russian scientist and science-fiction writer.  Nikolai Zhirov quotes[458.83] Yefremov, who saw the Mediterranean as the “cradle of all the great civilisations of antiquity such as those of Egypt and Atlantis” and believed that “it is not at all necessary to consider that the existence of an island in the Atlantic explains the continuity between the Mediterranean and American cultures.”

Atlantis II Deep (l)

Atlantis II Deep is the name of the largest submarine basin in the Red Sea reaching a maximum depth of 7,160 feet where hot brine is produced at 56°C. The Red Sea is an extension of the Rift Valley and is in a tectonically active region.

Atlantis II Deep

Gene Matlock quotes Rajeswar Gupta(a), the Bengali historian, who states that the Red Sea and the Mediterranean had in earlier times been connected by a strait. Coincidentally, the controversial Oera Linda Book supports this contention(b).




Armorica was the Latin name given by the Romans to what we know today as the Brittany peninsula. The region contains some of the most remarkable monuments created by the megalith builders, such as those found at Carnac and Morbihan,

ArmoricaPlato described the influence of Atlantis reaching as far as Italy and Libya (Tim. 25b). In Europe megalithic structures have been found extending all along the Atlantic seaboard and into the Mediterranean as far east as Italy(a) and all across North Africa including modern Libya and Egypt, it was understandable when some commentators concluded that these megalithic monuments were a cultural expression of the Atlanteans. The evidence available indicates that the spread of megalithic building was effected by a maritime based society. How much of this spread was brought about through military or trade expansion or just migration  is not known.

A number of French and German researchers have identified Brittany as the power centre of the Atlantean ‘confederation’, while the American writer Hank Harrison is working on a book in which he will nominate Morbihan as a possible capital of Atlantis. R. Cedric Leonard has also written an interesting article(b) on the megalithic monuments of Brittany.

While megaliths are also found in the Middle East and across Asia as far as Japan, their greatest concentration is in Western Europe with a suggested focal point in Armorica. The legendary sunken city of Ys, often associated with Atlantis, is reputedly located off the coast of Armorica.

Mediterranean Sea Level

Mediterranean Sea Level. There is general acceptance that, on more than one occasion, the Strait of Gibraltar was closed completely. Tectonic plate movement, worldwide sea level drops due to the onset of Ice Age glaciation or a combination of both, could have caused this. There is also clear undisputed evidence that the Mediterranean Sea has dried out completely on a number of occasions. What is not clear is when the last desiccation or partial drying-out of the Mediterranean ended. The conventional date given for the last breaching of a Gibraltar Dam is 5 million years ago. However, there is a small but growing opinion that there was a more recent breach of a dam within the memory of modern man and preserved in history and myth.

bathymetric medWhere one theory on the location of Atlantis is concerned, the existence of a Gibraltar dam before the end of the last Ice Age is critical, namely that Atlantis was situated near modern Cyprus. The site chosen by author Robert Sarmast is 1650 metres beneath the present level of the Mediterranean. His theory is totally dependent on proving the existence of this dam. It would seem prudent to have carried out a more detailed study of the evidence for a relatively recent removal of the dam before engaging in a very costly exploration over a mile under the eastern Mediterranean.

There are a number of facts that appear to suggest a more recent Mediterranean inundation but even collectively they do not offer any more than circumstantial evidence.

(i) The Mediterranean sea level must have dropped by as much as from 150 to 300 meters or more. Several years ago, by chance divers found submerged entrances (below sea level) in Southern France, which subsequently led them to discover the now famous prehistoric cave paintings there. There are many man-made stone structures around the Mediterranean that are now under water as well.

Cosquer Cave, near Marseilles, has its entrance 37 metres underwater. It contains several dozen works painted between 25000-17000 BC. The opening was once several miles inland until about 10000 BC when the sea began to rise at the end of the last Ice Age. It has been estimated that that it was originally at a height of 80 metres above sea level, according to anthropologist, James Q. Jacobs(a).  This cave art depicts the Auk, which had never been found this far north.

(ii) Submerged Maltese structures, although their inundation may have been caused by local seismic activity rather than global sea level changes.

(iii) H. S. Bellamy claimed[091] that ancient geographers hinted at the non-existence of the Strait of Gibraltar within human memory.

(iv) A modern Guide to Provence(b) also claims a relatively recent removal of the Gibraltar land bridge.

(v) Medieval Arab writers such as Al-Biruni, Al-Idrisi and Al-Mas’udi suggest the existence of a Gibraltar landbridge, again within the memory of man.

(vi) The sunken port of ancient Syedra in Turkey.

Mediterranean Sea

The Mediterranean Sea is at the heart of the Atlantis story. Solon brings the tale back from Egypt to Athens and relates how the Atlanteans controlled the Mediterranean as far as Tyrrhenia and Egypt. The Atlanteans attack Athens and Egypt. Although the Pillars of Heracles are now generally believed to have been located at the Strait of Gibraltar, a number of other locations in the Mediterranean are known to have been similarly designated at different periods. As I have argued elsewhere, the Pillars of Heracles were undoubtedly a designation for the Strait of Gibraltar from the time of Eratosthenes, there is clear evidence that it was applied to other locations in earlier ages and probably over time, it became a metaphor for the limits of Greek maritime knowledge.


I may be the first to claim here that modern studies of Homer’s Odysseus offer a possible argument in favour of a Central Mediterranean Atlantis. Armin Wolf, the German historian, has made a 40-year study of 80 theories regarding the route taken by Odysseus. Around 30 of these included maps, a number of which are included in Wolf’s book, Homers Reise: Auf den Spuren des Odysseus[669], a shorter version in English, including maps, is also available as a pdf file(a). It is obvious that although a reasonable degree of agreement exists between many of the theories regarding the position of the twelve specific locations recorded by Homer, those that confine the ‘wanderings’ to the Mediterranean, consistently keep all locations in the eastern basin and Central Mediterranean with the sole exception of the inclusion of Gibraltar which looks out of place on maps, with nothing on the way there or on the return trip. Wolf’s carefully thought out route does not include Gibraltar and in my opinion is a better reflection of actual Greek seafaring knowledge and naval capabilities at that time and adds a further suggestion, however inconclusive, that the Pillars of Heracles were situated in the Central Mediterranean.*Wolfgang Geisthövel follows Wolf’s conclusions in Homer’s Mediterranean[1578].*

Today’s leading theories regarding the location of Atlantis are virtually all related to the Mediterranean region. Between Morocco in the west and the Black Sea in the east there is an embarrassment of suggested locations.

The principal objection to a Mediterranean location for Atlantis is the extent of the island as described by Plato, which if accepted as written, could not have fitted anywhere in that body of water. He gives us measurements for the plain adjacent to the city as being 240×360 miles. However, it is widely agreed that most of Plato’s dimensions are highly suspect and exaggerated by as much as a factor of ten.

On the other hand if Atlantis had been located outside the Mediterranean it is difficult to understand how the disaster that destroyed Atlantis could also have devastated Athens and its hinterland when the two locations would have been over 1700 miles apart.*No single known natural disaster, such as an earthquake, could have affected the two cities at the same time. So if they were destroyed concurrently we must conclude that the two locations were situated in the same region and since Athens was clearly in the Mediterranean so must Atlantis. However, Plato does not explicitly say that the two armies were destroyed at the same time, although it seems to be implied.*

As stated in the Invasion entry, all ancient empires expanded through the invasion of adjacent territories and so there is no good reason to think that Atlantis’ attack was not launched against an Athens that was within easy striking distance. This proximity could possibly explain the inference that Atlantean and Athenian armies were destroyed simultaneously by some natural catastrophe!

Finally, please consider the following facts;

(1) Herodotus tells us that the ancient Greeks only knew of three continents, Asia, Europe and Libya (Africa) (Hist.4.42).

(2) Plato never called Atlantis a continent but consistently referred to it as an island.

(3) Finally, Herodotus also describes Sardinia as “the biggest island in the world.” (Hist.6.2)**, *confirming a lack of knowledge of the world beyond the Mediterranean.*

These three details taken together offer a compelling argument in favour of a Mediterranean Atlantis.

** Sicily is in fact larger in terms of area (25,708 v 24,090 km2). However, the coastal length of Sardinia is much greater than Sicily’s (1843 v 1115 km). Felice Vinci recently explained[019] how ancient seafarers measured territory by its coastal perimeter rather than by its area, as we do today. So Herodotus was correct according to the conventions of his day.


Hébert, Jacques (L)

Jacques Hébert is the author of Atlantide: La Solution Oubliee[373] concerning Atlantis. As a former Parisian police jhebert, Jacqueschief, he claims to have applied his skills in that field to solving the mystery of Plato’s island. He critically re-examines the original text and offers an interpretation that he believes provides a more rational and harmonious reading of the narrative. His conclusion is that Atlantis lay in the Indian Ocean and that its culture was derived from the Indus valley. He specifically identifies the Yemeni island of Socotra as part of the Atlantean civilisation

Hébert postulates that this empire had at least trade connections in the eastern Mediterranean and quite possibly had a colony in the region that produced the predecessors of the Phoenicians.

Hébert identifies Bab el Mandeb as Plato’s Pillars of Heracles, by assuming that Solon mistook the description of that strait, given to him by the priests of Sais, with the Strait of Gibraltar, which has similar features. The earthquake that destroyed Atlantis is attributed by him to a close encounter with an extraterrestrial body.

A 2004 interview with Hébert can be read online(a).

Flora and Fauna of Atlantis

The Flora and Fauna of Atlantis is mentioned by Plato in Critias;

“Besides all this, the earth bore freely all the aromatic substances it bears today, roots, herbs, bushes and gums exuded by flowers or fruit. There were cultivated crops, cereals which provide our staple diet. And pulse (to use its generic name) which we need in addition to feed us; there were the fruits of trees, hard to store but providing the drink and food and oil which gives us pleasure and relaxation and which we serve after supper as a welcome refreshment to the weary when appetite is satisfied – all these were produced by that sacred island, then still beneath the sun, in wonderful quality and profusion.” (115a-b)

James Bramwell noted how Leo Frobenius was convinced that his chosen Atlantis location of Yorubaland in Nigeria was reinforced by Plato’s description of the flora of his disappeared island[0195.119].

The lack of sufficient detail in the extract from Critias has led to a variety of interpretations. Jürgen Spanuth in support of his North Sea location for Atlantis has claimed[015.68] that during the Bronze Age the snow line in that region was higher than at any other time since the last Ice Age at 1,900 metres. He claims that as a result, grapes and wheat were cultivated there during that period.

The existence of the same species plants and animals on both sides of the Atlantic has been noted for some time, so when the Mid Atlantic Ridge (MAR) was discovered in the 19th century and subsequently combined with the realisation that sea levels had dropped during the last Ice Age, it was thought that a stepping stone, if not an actual landbridge, between the continents had been identified. This idea was popular with many geologists and botanists at the beginning of the 20th century, such R.F. Scharff and H.E. Forrest, both of whom also saw the MAR as the location of Atlantis, an idea that still persists today. Emmet Sweeney is a modern writer who also sees the earlier exposed MAR as an explanation for the shared transatlantic biota and is happy to identify the Azores as the last remnants of Atlantis[0700].

Andrew Collins has attempted to squeeze a reference to coconuts out of this text to support his Caribbean location for Atlantis. However, coconuts were not introduced into that region until colonial times(c)Ivar Zapp & George Erikson, driven by similar motivations had made the same claim earlier. My reading of the text is that Plato is describing food with which he is personally familiar.

Mary Settegast points out that around 7300 BC there is evidence of crop rotation including cereals at the Tell Aswad site in Syria.

The olive tree thrives best in the regions with a Mediterranean climate. Olive trees are mainly found between 25° and 45° N. latitude and, as for France, only in the Mediterranean area.

Ignatius Donnelly devoted Chapter VI(a) of his Atlantis tome to a review of the Atlantean flora and fauna. The print media at the start of the 20th century kept the general public aware of these theories(b).


(b) discovered&searchLimits=



The term ‘Continent’, is derived from the Latin terra continens, meaning ‘continuous land’ and in English is relatively new, not coming into use until the Middle English period (11th-16th centuries). Apart from that, it is sometimes used to imply mainland. The Scottish island of Shetland is known by the smaller islands in the archipelago as Mainland, in fact its old Norse name is Megenland, which means mainland. In turn the people of Mainland, Shetland, will apply the same title to the Britain, who in turn apply the term ‘continuous land’ or continent to mainland Europe. Consequently it is clear the term is clearly relative.

The term has been applied arbitrarily by some commentators to Plato’s Atlantis, usually by those locating it in the Atlantic. In fact Plato never called Atlantis a continent, but instead as the sixteen instances below prove, he consistently referred to it as an island, probably the one containing the capital city of the confederation or alliance!

[Timaeus 24e, 25a, 25d  Critias 108e, 113c, 113d, 113e, 114a, 114b, 114e, 115b, 115e, 116a, 117c, 118b, 119c]

A number of commentators have assumed that when Plato referred to an ‘opposite continent’ he was referring to the Americas, however Herodotus, who flourished after Solon and before Plato, was quite clear that there were only three continents known to the Greeks, Europe, Asia and Libya [4.42]. In fact prior to Herodotus only two landmasses were considered continents, Europe and Asia, with Libya sometimes considered part of Asia. So when Plato does use the word ‘continent’  [Tim. 24e, 25a, Crit. 111a] we can reasonably conclude that he was referring to one of these landmasses, and more than likely to either Europe or Libya (North Africa) as Atlantis was in the west, ruling out Asia.

Philo of Alexandria (20 BC-50 AD)  in his On the Eternity of the World(b) wrote “Are you ignorant of the celebrated account which is given of that most sacred Sicilian strait, which in old times joined Sicily to the continent of Italy?” (v.139). It would seem that in this particular circumstance the term ‘Sicilian Strait’ refers to the Strait of Messina, which is another example of how ancient geographical terms often changed their meaning over time (see Atlantic & Pillars of Herakles).

The name ‘Italy’ was normally used in ancient times to describe the southern part of the peninsula(d). Some commentators think that Philo was quoting  Theophrastus, Aristotle’s successor. This would push the custom of referring to Italy as a ‘continent’ back to the time of Plato,*who clearly states (Tim. 25a) that the Atlantean alliance “ruled over all the island, over many other islands as well. and over sections of the continent.” (Wells). The next passage recounts their control of territory in Europe and North Africa, so it naturally begs the question as to what was ‘the continent’ referred to previously? I suggest that the context, had a specific meaning, which, in the absence of any other candidate and the persistent usage over the following two millennia can be reasonably assumed to have been southern Italy.*

Centuries later, the historian, Edward Gibbon (1737-1794) refers at least twice[1523.6.209/10] to the ‘continent of Italy’. More recently, Armin Wolf (1935- ), the German historian, when writing about Scheria relates(a) that “Even today, when people from Sicily go to Calabria (southern Italy) they say they are going to the “continente.” This continuing usage is confirmed by a current travel site(c) and by author, Robert Fox in The Inner Sea [1168.141].

I suggest that Plato used the term in a similar fashion and can be seen as offering a more rational explanation for the use of the word ‘continent’ in Timaeus 25a, adding to the idea of  Atlantis in the Central Mediterranean.

*Giovanni Ugas claims that the Mediterranean coast of southern Spain and France, along with the Italian peninsula constituted the ‘true continent’ (continente vero) referred to by Plato. (see below)*


Furthermore, the text informs us that this opposite continent surrounds or encompasses the true ocean, a description that could not be applied to either of the Americas as neither encompass the Atlantic, which makes any theory of an American Atlantis more than questionable.

Modern geology has definitively demonstrated that no continental mass lies in the Atlantic and quite clearly the Mediterranean does not have room for a sunken continent .
