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.

Stieglitz, Robert (N)

Robert Stieglitz is Professor Emeritus of Ancient Mediterranean Civilisations at Rutgers University. He is stieglitza specialist in ancient seafaring. He contends that the Sea Peoples included the Philistines(a).

He appeared on the BBC documentary, Helike – The Real Atlantis and while he is obviously an Atlantis sceptic, when pressed he responded that since “Helike was the only city to disappear without a trace in one night, so if there’s a grain of truth at all to the story of Atlantis it’s the disappearance of Helike which inspired in Plato to write the myth of Atlantis.”(b) He subsequently developed this idea into a lecture(c).




Hughes, Bettany (t)

Bethany Hughes

Bettany Hughes (1968- ) is a well-known historian with a high media profile. She has presented one major TV documentary on the subject of Atlantis, specifically supporting aspects of the Minoan Hypothesis. This was Atlantis: The Evidence (Timewatch BBC TWO, 2010)(a) and more recently she has been trotted out to promote a new drama series Atlantis (BBC 2013).

She wrote a preview of this BBC series, for The Telegraph(b), which together with her earlier documentary still raises questions for me about her competence to deal with this subject at all. In her article she refers to the Atlantis story as a moral fable, ignoring the fact that not only were the ‘wicked’ Atlanteans destroyed, but so also were the ‘good’ Athenians.

She then alludes to Plato’s mention of the use of red, black and white stone in Atlantis. It is well known that this combination is common in volcanic regions and has been noted at a number of proposed  Atlantis sites; The Canaries, Bolivia, Morocco, Azores, Sardinia and southern Spain.

Next, Hughes tries to explain away the navigation hazard described by Plato, identifying it as pumice. Plato clearly describes mud shoals as the barrier. This would be fine, except that Plato also tells us that the hazard still existed in his day, a thousand years after the eruption. It is improbable, to say the least that pumice would have lingered for a millennium!

These miserable attempts to link Thera and Atlantis are bad enough, Hughes does not explain how Plato repeatedly refers to the Atlantean invasion coming from their base in the the west (Tim.25b & Crit 114c), while Thera/Crete is north of Egypt and south of Athens. Where were the Pillars of Heracles and where were the Minoan elephants?

I would expect a professional like Hughes to offer a more comprehensive review of ALL the information provided by Plato and not dismiss whatever conflicts with her opinion as “sheer fantasy”. This picking and choosing from Plato’s text is not good enough without any justification for her selectivity.




Volcanism is not part of the Atlantis story as related by Plato. His narrative clearly attributes the destruction of Atlantis and the Athenians to flooding and earthquake. Admittedly, flooding can be the result of some volcanic activity, but in the absence of any evidence to support this view in the case of Atlantis, the idea is only supposition. While most accept that Atlantis was named after its first king, Atlas, Frank Joseph’s fertile imagination suggests[104] that ‘the island of Atlantis was named after its chief mountain, a dormant volcano’. For those that place Atlantis in the Atlantic the idea of volcanic or seismic activity as the cause of the flooding of Atlantis AND Athens are hard pressed to suggest a location for this activity that would explain two catastrophes two thousand miles or more apart.

However, the red, white and black stone that Plato may be related to volcanic eruptions that produce rock of tufa (red), pumice (white) and lava (black). Pumice has been found at various locations in Egypt and identified as originating not only from Thera, but also from eruptions on the Greek islands of Nisyros and Giali as well as the Italian Lipari Islands(o).

Jelle Zeilinga de Boer and Donald Sanders are the authors of Volcanoes in Human History[681] in which they support the idea that the eruption on Thera was a factor in the development of the Atlantis story and also suggest a link with the Flood of Deucalion.

Nevertheless, a recent book by William Lauritzen, The Invention of God[745], makes a convincing case for accepting volcanic activity as the inspiration behind some of the imagery of ancient mythologies and most major religions. A recent article(i) on the BBC website expanded on this further. Lauritzen also suggests that the pyramids were meant to represent volcanoes.



The most active volcanic region of Europe is to be found in Italy, where Etna and Stromboli have been continuously erupting for thousands of years(b).  There is a report that a 6000 BC extreme eruption of Etna resulted in a tsunami 130 feet in height which swept the Mediterranean(c). However, the most devastating prehistoric volcanic eruption discovered so far seems to have been in Siberia 252 million years, which may have led to the most extensive mass extinction of life on earth(e). This is now rivalled by Tamu Massif in the Pacific mentioned below.

The cataclysmic volcanic eruption of Thera in the second millennium BC has had a strong level of support as the cause of Atlantis’ collapse, a view endorsed by recent television documentaries and an IMAX film. The Greek volcanologist, George Vougioukalakis, whose research is featured in the aforementioned film, is convinced that the eruption of Santorini offers the most rational explanation for the truth behind Plato’s story(a). However, he dissents from the recently expressed view that pumice found on the Northern Sinai Peninsula was transported there by a tsunami generated by the eruption of Thera and prefers to believe their transportation there was by normal sea currents.

Apart from Santorini, Jim Allen had initially proposed the Andean village of Quillacas, which lies on top of a volcano, as the site of Atlantis, but later found that the nearby site of Pampa Aullagas had a greater correspondence with the description of Atlantis. More recently Richard W. Welch has suggested the eruption of a supervolcano in the Atlantic as the cause of Atlantis’ demise. And so the idea of a volcanic destruction of Atlantis still has some support!

Since January 2011, Santorini has shown some signs of a volcanic reawakening(d).

In September 2013 studies revealed(f) what may be the location of the largest volcano ever to have erupted on our planet. It would have been the size of the British Isles and situated underwater in the northwest Pacific and known as Tamu Massif. It would have rivalled the Olympus Mons on Mars, but fortunately has been dormant for 140 million years.

March 2014 saw a post on Dale Drinnon’s website(g) take the linkage between Atlantis and a volcano rather further with the suggestion that “the capital city of Atlantis in Plato’s description was built in the caldera of an extinct volcano and that many of the features of the description are volcanic in origin.The “Poseidon’ temple is the pyramidal volcanic neck, an erosional feature that stood out like a conical mound some hundreds of feet in diameter and possibly some hundreds of feet high on the outside. there was a tunnel bored through this aligned East and West, to allow the sunlight in at the beginning and the end of the day for certain rituals.”

In December 2014 a report from Princeton University revealed that a massive series of volcanic eruptions 66 million years ago can be aligned with the extinction of the dinosaurs and should be included as part of the cause of that extinction along with the Yucatan meteorite impact(h).

The Laki volcano in Iceland erupted in 1783 killing 9,000 local people but more dramatically causing the Nile Valley population to be cut by a sixth, according to a study published by scientists at Rutgers, The State University of New Jersey. “The study is the first to conclusively establish the linkage between high-latitude eruptions and the water supply in North Africa”(j).

A 2015 report(k) suggests that a series of North American volcanic eruptions in 536 AD had such a detrimental effect on the climate of Europe that contributed to the demise of the Roman Empire.

Furthermore, there is now evidence(m) that the eruption of El Chicon volcano in Southern Mexico around 540 AD led to the disruption of the Maya civilisation. Can there be a connection between these two events?

However, David Keys in his book, Catastrophe[1130], has proposed that a massive eruption of Krakatoa around 535 AD caused disruption on a global scale. Matthew Toohey from the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, has suggested the possibility of a double event involving both El Chicon and Krakatoa!

Recently the longest (1,200 miles) continental volcano chain was identified in Australia(l).

The BBC reported(n) in 2016 that Deep-sea volcanoes are so remote, until recently we did not even know they existed” and although “We do not see them erupt, yet more than half of the Earth’s crust can be attributed to their dramatic explosions” and “In fact, the mid-ocean ridges form the largest volcanic systems on Earth. But as they are largely hidden from sight, they have long remained elusive.” 

*In July 2017, the BBC offered an interesting article on the potential ongoing threat from supervolcanoes around our globe(p)  and the inevitability of a future eruption.*

Murex is the name of a family of sea snails that led to the murex[1]Phoenicians controlling the very lucrative trade in purple dyed silk(b). Some have attributed the origin of the name ‘Phoenicia’ to a Greek word meaning ‘purple’.

The dye had been extracted from the Murex snails and the resulting cloth was considered highly desirable to such an extent that in later years the colour was reserved for members of the Roman imperial family. It took 10,000 snails to produce one gram of dye, making it extremely expensive. Unfortunately, the process involved putrefaction and the use of urine, contributing to an extremely melodious operation.

Demand for this exclusive dye persisted for nearly 3,000 years. Purple was also the preserve of cardinals in the Roman Catholic Church, equating them with kings, until the 15th century when red was decreed for them, a situation that still pertains. Professor Maria Michaela Sassi of Pisa University has written an interesting paper(k) on the ancient Greek perception of colour, in the course of which she refers to the processing of the murex snail, noting that “Various nuances from yellow to green, to blue, to red could be obtained depending on how much water was added and when the boiling process was stopped

There is some suggestion that the Phoenicians were not the first to develop this process following the discovery of mounds of Murex shells on Crete dated to the early 2nd millennium BC. It is also claimed that the Italians of the same period also knew of the procedure(g) .

Over a century ago James Baikie noted[142] that “the dyeing of robes with the renowned ‘Tyrian purple,’ must be denied to them and claimed for the Minoans. In 1903, Messrs. Bosanquet and Currelly found on the island of Kouphonisi (Leuke), off the south-east coast of Crete, a bank of the pounded shell of the murex from which the purple dye was obtained, associated with pottery of the Middle Minoan period; and in 1904 they discovered at Palaikastro two similar purple shell deposits, in either case associated with pottery of the same date.”

It is difficult not to see a possible link between murex dye developed by the Phoenicians and the biblical injunction to Jews of the same region to wear blue (tekhelet) tassels (tzitziyots) from the corners of four-cornered garments. Recently, near the caves of the Dead Sea Scrolls a rare 2,000-year-old fragment of cloth  was discovered(c) that had been treated with the Murex dye.

Michael Hübner pointed out that that apart from Murex, Northwest Africa and the Canaries were home to the Indigo plant and Orseille lichen, which both can be used to produce blue dyes(h).

Frank Joseph notes that Berber village elders even today wear special dark blue robes when meeting in council. This is seen as an echo of the custom of the kings of Atlantis as recorded by Plato Critias (120b-c).

A similar purple dyeing process was discovered in Central America(a) adding to the suggestion of pre-Colombian contacts between Europe and the Americas. In September 2016, it was announced(e) that “a George Washington University researcher has identified a 6,200-year-old indigo-blue fabric from Huaca, Peru, making it one of the oldest-known cotton textiles in the world and the oldest known textile decorated with indigo blue.” Unfortunately, the source of the dye was not identified. Even today, in Oaxaca, Mexico, shellfish dyeing is still carried on, but using the milky liquid from the purpura patula, a marine mollusc(f), unlike the murex mollusc which is killed in the process of obtaining the ink, the purpura have always been milked alive and left to replenish their dye fluid for harvesting at another time.  A similar procedure is still employed by the Boruca people of Costa Rica (l). If there was a dyeing link between the Americas and the Mediterranean. in which direction did it initially travel?

Pliny the Elder noted that Uba, a Numidian king, intended to establish Murex farming on the Hesperides located 12,000 km from Cadiz. This comment has been linked with a mention by Diodorus Siculus regarding a large island know to the Phoenicians outside the Pillars of Heracles.  Advocates of an Atlantic location for Atlantis have seized upon these two references, although the linkage is somewhat tenuous.

There is an extensive online article(d) on the history and use of ‘Tyrian Purple’.

A few years ago the BBC published a short piece(i) on the chemistry behind the Tyrian Purple. In August 2018 they returned to the subject with a more extensive article(j) outlining the mythology and history associated with the dye.
