    September 2023. Hi Atlantipedes, At present I am in Sardinia for a short visit. Later we move to Sicily and Malta. The trip is purely vacational. Unfortunately, I am writing this in a dreadful apartment, sitting on a bed, with access to just one useable socket and a small Notebook. Consequently, I possibly will not […]Read More »

    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 »

Casey, Kevin A. & Patrick J.

Kevin A. & Patrick J. Casey are the American authors of a series of papers currently available on the academia.edu website(a), which are concerned with a globally catastrophic event that occurred 13,000 years ago. providing them with a title of ’13K Theory’. The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period.

They claim that this event wiped out the megafauna, altered the Earth’s axis and created our mountains, the Earth being generally flat before the dramatic episode! They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the conclusions of Richard Firestone and his colleagues.

Their final paper is entitled Atlantis Revisited(b), in which they nominate Rockall as being ‘by far’ the most likely location of Atlantis. They also claim that the war between the Atlanteans and the Greeks took place before the 13K Event! Enjoy.

Younger Dryas

Younger Dryas is also known as Dryas III was a mini Ice Age that lasted from around 10,700 BC until around 9600 BC. It is named after a wildflower called Dryas octopetala that flourished during this relatively short period. In Ireland, the period is known as the Nahanagan Stadial and in Britain as the Loch Lomond Stadial. For about thirteen hundred years the glaciers had been slowly retreating until within a short timespan temperature dropped and they began to advance again. The cause of this cooling is not entirely clear. One view is that a sudden release into the North Atlantic of vast quantities of freshwater that had been contained by huge ice dams is assumed to have closed down the Gulf Stream, resulting in a twelve-hundred-year lowering of global temperatures. There is evidence that the change only took one or two decades. The same threat is said to exist today with the possibility of the melting of the Greenland ice cap. It also seems that this YD cooling ended with the same rapidity.

In 2011 a paper by Nicholas Pinter et al offered a critical review of the evidence available at that time which, from their perspective, did not fully support the YDIH(z).

A recent application of archaeoastronomy by Martin Sweatman and Dimitrios Tsikritsis led them to conclude that the carved symbols at Göbekli Tepe recorded an encounter involving the explosion or impact of part of Encke’s Comet around 13,000 years ago, which triggered the Younger Dryas Event that provided the impetus for the Neolithic Revolution. Sweatman later expanded their work in his book Prehistory Decoded [1621] and an article on the Ancient Origins website(k). In June 2021, Sweatman had a paper entitled The Younger Dryas impact hypothesis: a review of the impact evidence’ published in the journal ‘Earth Science Review’ of the University of Edinburgh(u).

Kevin A. & Patrick J. Casey maintain that a globally catastrophic event occurred 13,000 years ago(j). The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period. They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the conclusions of Richard Firestone and his colleagues.

A completely different view is expressed in Rod (Carl) Martin’s latest book [1623], where he proposes that the Younger Dryas ended as a result of a catastrophic event. Is it possible that there were two cataclysmic episodes? John Ackerman, a keen follower of Immanuel Velikovsky claims that there were two such events related to “the capture of the Moon into its current orbit,” marking the beginning and the end of the Younger Dryas period(q).

A somewhat technical paper, published in July 2020, challenges the comet impact theory because of geochemical anomalies, Instead, they argue that the YD event was a consequence of volcanic activity(s), rather than an impact! Martin Sweatman refutes this in a paper on Graham Hancock’s website(i).

In 2015, a paper constraining the impact date to within 100 years using Bayesian statistical analyses, now proposed as 12,835 -12,735 years ago(h).

Coincidentally, Emilio Spedicato independently concluded that it was a cometary impact in the North Atlantic that was responsible for the Younger Dryas. Subsequently, when temperatures rose again it resulted in the flooding of vast areas of low-lying landmasses that in Spedicato’s opinion included Atlantis, which he locates in Hispaniola.

Conflicting evidence regarding the possibility of the Younger Dryas being caused by such an impact is impartially outlined on the internet(a).

The November 2013 issue of the BBC Focus magazine (p.30) had a brief article on the impact theory, noting that the northern hemisphere saw a drop of as much as 15°C around 11,000BC. In the absence of a suitable impact crater of the right age, there is still much scientific scepticism(b).

However, in early 2017, further possible evidence of an impact at the start of the Younger Dryas was offered by a team led by Christopher Moore of the University of South Carolina, when they identified a distinct layer of platinum in the soil that coincided with the start of YD. Commenting on this anomaly Moore noted that “Platinum is very rare in the Earth’s crust, but it is common in asteroids and comets.”(e) In 2019, Moore published further data(m) supporting the extraterrestrial impact theory, based on studies carried out on sediments, which date back 20,000 years, from White Pond Lake, situated in southern Kershaw County, South Carolina. “Other examples of excessive platinum grains have been found across Europe, western Asia, Chile, South Africa(r) and North America.” (n)

In early 2018, two papers were published online(i), reinforcing the YD impact theory and adding evidence that the event resulted in a conflagration that may have consumed ~10 million km2, or ~9% of Earth’s terrestrial biomass.” Related to this is a paper by Andrew Collins that draws attention to the ‘Usselo horizon’, a charcoal-rich layer of between 1 and 8 inches, found on all continents, indicating widespread fires, now dated to 12,900 years ago(l).>An additional paper by Hans Kloosterman offers additional background information on the charcoal-rich layer(ab).<

Ice cores from Greenland indicate a further cooling period circa 6200 BC that may be related to the abandonment of many Neolithic settlements during this period. Other periods of abrupt climate change have been identified from 3800 BC to 3500 BC and 2800 BC to 2000 BC.

The fact that Plato’s apparent date for the demise of Atlantis, circa 9600 BC, roughly corresponds with the current, best estimate for the date of the Younger Dryas is interesting but unfortunately not conclusive proof of any direct connection. In the absence of any supportive archaeological evidence, a linkage between Atlantis and the Younger Dryas will have to remain a matter of faith rather than fact. Interesting but inconclusive.

In 2017, Graham Hancock reviewed the Younger Dryas debate over the previous decade in a lengthy essay(v). This was prior to the publication of America Before. He finished with the following comment. Perhaps the lost civilization that I have spent the last quarter of a century trying to track down had its most significant outpost, possibly even its heartland, in North America in the period BEFORE the Younger Dryas cataclysms of 12,800 to 11,600 years ago?”  Hancock is inferring here that there was a single global civilisation, a hyperdiffusionist stance that I consider indefensible.

A short paper by John Patrick Hill offers a theory that requires more than faith to accept it; he wrote “Just over 12 thousand years ago, the world was struck by an immense meteor group. It destroyed all of North America and much of Europe and went weIl beyond……… I found proof to support that the creators of the Giza Three and Stonehenge used the Barringer Crater in Arizona as part of the geometry for their massive structures.”  Later he reveals that at “Giza, when one takes the distance between the outside corners of the three large pyramids there, that distance is equal to 0.72 miles, the exact distance (diameter) at Barringer.” An expanded version of his paper is available online(t).

In another paper Hill(aa) says that “the Younger Dryas Meteor Event struck 12.8 thousand years ago and it was so large, it is wrote down not only in geologic records but also in holy books, as Noah’s Flood.”

Recent discoveries in northern Sudan of dozens of skeletons, the majority of whom were killed by flint-tipped arrows, have led to the suggestion(c) they were the result of food shortages resulting from the Younger Dryas that in turn led to warfare over diminished food availability.

I note that Robert Schoch claims that there is no evidence to support the Younger Dryas impact theory, instead, he believes that “it was most likely due to reduced solar activity at that time, a solar shut-down.”(o) Schoch’s wide-ranging critique has been refuted by the Comet Research Group.(p)

In 2020, James Lawrence Powell (1936- ), a noted geologist, author, former college president and museum director entered the Younger Dryas debate with the publication of Deadly Voyager [1911]. In it, Powell offers wholehearted support to the Younger Dryas Impact Hypothesis (YDIH), understandably generating a favourable review from Graham Hancock(w).

>In 2020, Tony Petrangelo argued that the Younger Dryas event did not destroy Atlantis, but that it was more compatible with the story of Phaeton(ac).<

Even more important, is that Powell’s book induced a number of heavy-duty critics of YDIH, including Michael Shermer to change their opinion(x).

Powell offered a further review of the YD debates in a 2022 paper(y).

Rockall *

Rockall is an uninhabited islet in the North Atlantic, northwest of Donegal in Ireland. It appears to have been first marked on a map in 1640(c). It is first mentioned in literature in 1716 and referred to by locals as Rocabarraigh, which is also the name of “a mythical rock which is supposed to appear three times, the last being at the end of the world.”(m).

This ostensibly insignificant piece of stone is around 80ft by 100ft at the base and approximately

70ft in height. Nevertheless, its ownership is disputed by Ireland, Iceland, the Faroe Islands and the United Kingdom.

Rocabarraidh which was a mythic island referred to in the folklore of the Lordship of the Isles, a Scottish title, is generally accepted to be an early allusion to Rockall. The Atlantic rock is considered as part of the Hebridean parish of South Harris.

In June 1997, Greenpeace declared Rockall to be the independent state of Waveland(f).

Jean Deruelle credits Robert Graves with being the earliest, although only briefly, to consider the Rockall Bank as the location of Atlantis(e).

Recently, a new claim has been made in connection with Rockall, namely, that it is a remnant of the Atlantis highlands, with the plain so vividly described by Plato, now situated under the sea to the southwest of the rock. Two extensively illustrated French websites(a)(b) expound this theory. Which, however, are somewhat less than convincing. However, a 1938 newspaper report(d) suggests that a proposed linkage with Atlantis goes back much further!

In December 2016, Jonathan Northcote published 16.484ºW 58.521ºN, Atlantis, Found?[1369], in which he offers spirited support for this location using a mass of geological data and underwater topography. He also suggests that Gades may have been Ireland. In January 2019, Northcote revised his book with additional material and published this second edition with the title of Atlantis, Found? An investigation into ancient accounts, bathymetry and climatology [1611].

Stuart L. Harris, the prolific American researcher, has, in recent private correspondence with me, supported the vicinity of Rockall as the location of Atlantis, dating its demise to around 9577 BC. He later expanded on this in a highly speculative paper published on the Academia.edu website.

At the end of September 2018, the UK’s Daily Star, a well-known comic for adults, tried to revive the idea of Atlantis in Frisland(g). They based their brief article on the speculations of Matt Sibson, presented as an ‘expert’, who admits that “there are still some questions that need clearing up.” I would like to know why Frislanders in the middle of the last Ice Age would want to attack a non-existent Athens 4,000 km away. If Sibson is considered to be an expert historian, my cat is a brain surgeon. Jason Colavito had a few words to add regarding Sibson’s pathetic claims(h).

Incredibly, a week later the same ‘newspaper’ cited Sibson again, this time claiming that Rockall was the remains of Atlantis(i), an equally silly idea that is not new. The UK’s online Express recycled this nonsense in January 2020(k).

Kevin A. & Patrick J. Casey have published a series of papers on the Academia.edu website outlining a globally catastrophic event that occurred thirteen thousand years ago, which they refer to as the ’13K Event’, but is more popularly known as the onset of the Younger Dryas period. In February 2019, they published Atlantis Revisited (j), in which they claim that Rockall was the location of Atlantis. 

Less extreme is a claim by John Esse Larsen that in support of the theory that Homer’s Odyssey refers to adventures in the North Atlantic he suggests that Rockall is referenced in Odyssey 10.513(l).
