    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.Read More »

Fundamentalist Atlantology

Fundamentalist Atlantology is a term that I use to describe the idea that everything written about Atlantis by Plato, must be taken at face value. In other words when he refers to 9,000 years, this along with all the other numbers he uses in relation to the dimensions of the plain of Atlantis, its structures or its military manpower should be accepted literally! Such an acceptance flies in the face of both common sense and science, particularly in the case of Plato’s dating of Atlantis, while the dimensions he has for the ditch surrounding the plain of Atlantis were deemed incredible (his word) by Plato himself (Crit.118c), he felt obliged out of deference to Solon’s reputation he recorded the details as he received them.

Without wishing to offend anyone, I believe that acceptance, for example, of Plato’s/Solon’s numbers is comparable with the belief of religious fundamentalists who hold that creation’took just six days.

Although it is understandable that researchers have accepted Plato’s details without question, there has been extensive research over the past century into seeking more rational explanations for many of those more difficult passages in the Atlantis narrative which has produced alternative explanations that are compatible with both science and common sense.

While Plato’s 9,000 years were initially, rather glibly dismissed as a transcription error and that hundreds and not thousands had been intended, it has been demonstrated that the ancient Egyptian priesthood used a lunar calendar so that the ‘ýears’ were in fact months, which was noted in the 4th century BC by Eudoxus of Cnidos and repeated by Manetho and Diodorus Siculus. This would reduce the timeline by a factor of twelve. Another explanation was put forward by Rosario Vieni who proposed that the ‘years’ actually referred to seasons of which there are three in the Egyptian solar year. These, as far as I am aware, are the principal alternatives suggested in place of a literal reading of 9,000 years. After all, neither Athens or Egypt was home to anything more than primitive societies 9,000 years before Solon’s visit.

A further example concerns the size of Atlantis, which Plato consistently referred to as an island and never a continent and is described by him as greater than Libya and Asia combined. Irrespective of how extensive in size the Libya and Asia in question were, the Greek word for greater – meizon, actually relates to greater in strength, power or influence not extent. A few years ago Thorwald C. Franke pointed out that the traditional enemies of Egypt came from Libya and Asia, so that to describe the threat from Atlantis as greater than Libya and Asia combined indicates how great the threat from Atlantis was.

The more contentious issue of the actual location of the Pillars of Heracles, I will not go into here, suffice it to say that a number of valid competing arguments have been put forward in favour of locations other than the Strait of Gibraltar. In fact all of them could have been correct at different times, changing their position as the Greek colonists and traders gradually moved westward. Eventually, I believe that at some point in time the term simply became a metaphor for the limits of the world as generally known to the Greeks.

My point is that understandable difficulties exist in the Atlantis texts and that a number of sensible alternative explanations have been put forward, which will be individually tried and tested until a consensus emerges, in the same way that the idea of a geocentric universe was gradually replaced by the simple fact that our little planet revolves around the sun.


Thera is an ancient name for today’s Aegean archipelago of Santorini, which are the remains of a volcanic island.

Only two of the islands are inhabited, the main island, Santorini and Therasia, which had been joined before the 16th century BC eruption. Recent excavations have revealed a pre-eruption settlement on Therasia(x).

Pre-eruption Thera

Pre-eruption Thera

Although it exhibited low-level activity in 1939-41 and 1950-51, it was in 1926 when it last erupted violently, destroying many hundreds of buildings in less than a minute. Eruptions of similarity intensity occurred in 1650, 1707 and 1866. It was also the site of probably the most powerful and destructive volcanic explosion in the Mediterranean during the Bronze Age. Although the exact date of this event is still the subject of some controversy, the most recent evidence(a) indicates a date around 1613 BC ±13years, while archaeologists are more supportive of a date circa 1500 BC.

Professor Floyd McCoy of the University of Hawaii has written and broadcast extensively on the matter of the Late Bonze Age eruption of Thera, including a paper delivered to the 2005 Atlantis Conference. In it, he noted that “New finds of tephra – ash and pumice – both on land and on the seafloor indicate a far larger eruption than previously assumed, suggesting a volume of at least 100 km3 of tephra (bulk volume) ejected, perhaps more. Such a volume ranks the eruption on the Volcanic Explosivity Index (VEI) at 7.0, equivalent or larger than the 1815 eruption of Tambora (‘the year without a summer’), ten times larger than the eruption of Krakatau in 1883, and approximately 100 times that of Mt. St. Helens in 1980.”[629.311]

The 1500 BC date was supported by David A. Warburton who edited the Acts of the Minoan Eruption Chronology Workshop in 2007(af). The workshop provided a good overview of the Theran eruption dating debates, Warburton’s own comments are to be found in the Epilogue.

There was clearly a series of eruptions that ended with a final enormous explosion that has been linked to the ending of Minoan civilisation on Crete, the Plagues of Egypt and agricultural failures throughout the Eastern Mediterranean. For a geologist’s view of the island’s dramatic history, Walter Friedrich’s book[428]is hard to beat. His book supports a 1640 BC date for the eruption although he has subsequently revised this to 1613 BC. Sturt W. Manning supports[957] a 1628 BC date and Mike Baillie has offered dendrochronological evidence for a 1628 BC eruption date at the 2011 Quantavolution conference in Athens(j). This converges with McCoy’s date above. However, the dating of the eruption continues to be controversial as this December 2012 link(i)demonstrates.  At the heart of the problem is that acceptance of an early 17th century BC date for the event conflicts with established Egyptian chronology. While the exact year of the eruption continues to be debated, there is now scientific evidence that it occurred in early summer(s).

A 2014 paper published in Antiquity by Paolo Cherubini would appear to confirm the 16th century BC as the date of the catastrophic eruption ruling out an earlier date as untenable(o). In the same year, the University of Birmingham published a report(u) that supported the 1625 BC date. The earlier Antiquity paper prompted a response by a group, led by Sturt Manning later in 2014(y).

In August 2018, an interdisciplinary group led by dendrochronologist Charlotte L. Pearson published a paper(ab)(ad), which concluded that the eruption of Thera took place in the 16th century BC. This conclusion was the result of using a combination of ‘dendro’ along with high-resolution radiocarbon dating methods. In April 2020, a new report in the journal Proceedings of the National Academy of Sciences explained how a new study of the wood of an ancient grove of juniper trees, which suggested that the volcano blew its top around the year 1560 B.C.”(ae)

October 2018 saw further evidence for an early 16th century BC date for the eruption emerge after the radiocarbon dating of some olive wood found on Therasia, one of the Santorini group(z). The same month saw the publication of a paper on the ResearchGate(aa)  website date the event to 1727-1600 BC!

The doctoral thesis of Dr. David Sewell explores the cultural effects of the Theran eruption and can be read online(h).

The volcanic ash deposited by the Theran eruption was centuries later to be used in huge quantities to manufacture cement for the construction of the Suez Canal. It was during the mining of this material that workmen encountered large stone blocks under the layers of pumice, indicating buildings of a great age.

Luana Monte has written a rather ‘forced’ argument in which she claims that Thera can be identified as biblical Tarshish(ac) .

It is claimed by many that a garbled Egyptian description of this devastating event was the basis for the story of the destruction of Atlantis. Louis Figuier was the first, in 1872, to publicly link the demise of Atlantis with the explosion on Thera. Opponents of this theory counter it by pointing out that Plato describes the inundation of an island much larger than Santorini or Crete, located in the Atlantic following an earthquake, not a volcanic eruption many thousands of years earlier. Various attempts have been made to reconcile the Minoan Theory with these apparent inconsistencies with Plato’s text. They are discussed separately under

It was announced at the end of February 2010 that the BBC was about to air a dramatisation of the Theran disaster as well as a documentary on the eruption as its influence on the development of Plato’s story of Atlantis. June 2010 saw the historian, Bettany Hughes, front a disappointing BBC Timewatch Special, which also promoted the idea of the eruption on Thera as the inspiration for Plato’s story of Atlantis. The material introduced as evidence was highly selective and, for me, unconvincing. A few parallels between Thera and Plato’s description were trotted out, while the more numerous differences were ignored!

Alain Moreau has written a highly critical review(v) of the idea that the island of Thera/Santorini had been home to Atlantis.

Dr. Dora Constantinidis who studied under Prof. Christos Doumas delivered a lecture in Melbourne on May 29th 2014 with the inviting title of Unravelling the Atlantis Myth at Akrotiri. However, the primary purpose of the talk was not to advance our knowledge of Atlantis but to encourage the sale of Bronze Age inspired merchandise(p).

Another twist on the Thera explosion is offered by Andis Kaulins who suggests that there is a connection Theran eruptionsbetween that event and the Biblical story of Sodom and Gomorrah(g), while Riaan Booysen has linked two separate Theran eruptions with two Exodus events in the Bible(k), offering as evidence, the existence of two distinct Theran ash fallout areas, caused by different wind directions at the time of the events.

Initially, it was thought that the collapse of the Theran caldera generated very destructive tsunamis, but new studies have concluded(w)  that instead that it was the violent entry of pyroclastic flows into the sea that triggered the tsunamis.

A further possible consequence of the Theran eruption(s)  was proposed after the discovery of the Nebra Sky Disk(n), which was buried about 3,600 years ago. This is suggested Nebra Sky Diskto have resulted from the volcanic ash generated by the eruption blotting out the sun for up to 25 years. It is thought that the Disk had been used to synchronise the lunar and solar calendars(l) and when this was no longer possible the Disk was buried as some form as offering. A contrary view is offered elsewhere on the Internet(m), as well as further controversy(t) led by Peter Schauer from the University of Regensburg.

Andis Kaulins has also written an extensive paper on the Nebra Sky Disk. A 2014 update(r) on the Disk was posted by Claudia Bracholdt.

>2020 brought further debate with the claim in an extensive paper that the date of the Disk should be brought forward to the 1st millennium BC(ag). This was followed by a shorter but vehement rebuttal(ah).<

An extensive bibliography of books and articles on the subject of Thera can be found on the Internet(b).
