Mariolakos, Ilias D.

Ilias D. Mariolakos is professor emeritus of Geology and Palaeontology at Athens University. In 2010 he presented a paper(a) to the 12th International Congress of the Geological Society of Greece, in which he concluded that the prehistoric Greeks were quite familiar with the Atlantic and its Gulf Stream. He also identifies Iceland as Ogygia, based on his interpretation of the writings of Plutarch.

Mariolakos further maintains that the ancient Greeks*exploited the Michigan copper mines to supply the needs of their bronze industry. Their expertise was accumulated between the beginning or end of the 3rd millennium BC until shortly after the conclusion of the Trojan War towards the close of the Mycenaean period at the end of the 1st millennium BC. The onset of the ‘Dark Ages’ saw this maritime knowledge ‘forgotten’ until the ensuing Archaic Period when Greek civilisation revived.

Jason Colavito has accused Mariolakos of borrowing heavily, without attribution from the work of Wilhelm Christ who associated Atlantis with the SeaPeoples(c).

Mariolakos bases his conclusions on the works of Homer, Hesiod, Orphic poetry and Plutarch as well as the 20th century writer Henriette Mertz.

Homer (c. 8th cent. BC) is generally accepted as the author of the Iliad and the Odyssey, regarded as the two greatest epic poems of ancient Greece. A recent study of the Greek used by Homer has enabled scientists from the University of Reading to confirm that the language used is compatible with that used in the 8th century BC, in fact dating it to around 762 BC(i).

It should also be noted that over 130 quotations from the Illiad and Odyssey have been identified in Plato’s writings(s). George Edwin Howes (1865-1942), an American classicist, produced a dissertation[1458] on Homeric quotations in Plato and Aristotle.

Almost nothing is known of his life. He has been variously described as mad, blind and even mythical. Andrew Dalby, the English linguist, has gone so far as to claim[0591] that the author of the two famed epics was in fact a woman! While in 1897 Samuel Butler, the novelist, was even more specific when he proposed that Homer was a Sicilian woman(j).

For centuries it was assumed that the content of these Homeric poems was the product of his imagination, just as the historical reality of Homer himself has been questioned. In 1795, F.A. Wolf, a German academic declared that ‘Homer’ was in fact a collective name applied to various homerpoets whose works were finally combined into their present form in the 6th century BC. Wolf’s ideas sparked furious argument among Greek scholars that still resonates today. Now (2015), historian, Adam Nicholson has claimed that the author ‘Homer’ should not be thought of as a person but instead as a ‘culture’(o).

The identification of the site at Hissarlik in modern Turkey as Troy by Heinrich Schliemann led to a complete re-appraisal of Homer’s work and, of course, further controversy. Homer’s Iliad is the story of the Trojan War and it has been suggested that in fact he had compressed three or more Trojan wars into one narrative. What is not generally known is that there are also ancient non-Homeric accounts of the Trojan War(q).

Kenneth Wood and his wife Florence have built on the research of his mother-in-law, the late Edna Leigh, and produced, Homer’s Secret Iliad[391], a book that attempts to prove that the Iliad was written as an aide memoire for a wide range of astronomical data.

Allied to, but not directly comparable with, is the astronomical information identified in the Bible by the likes of E. W. Maunder (1851-1928)[1137].

Guy Gervis has adopted some of their work and specifies a date of around 2300 BC for the events described in the Iliad and Odyssey, based on an analysis of this astronomical data(n)Harald A.T. Reiche held  similar views which followed some of the ideas expressed in Hamlet’s Mill[0524]  by Santillana & Dechend who were colleagues of Reiche at M.I.T. They also claimed that “myths were vehicles for memorising and transmitting certain kinds of astronomical and cosmological information.”

Much has been written about the historicity of Homer’s epic accounts, including a good overview on Wikipedia(ab). Many have concluded that Homer did use real events, even if they were frequently dressed in mythological clothing compatible with the literary conventions of his day. I consider Plato to have treated the story of Atlantis in a similar manner.

A recent study of solar eclipses recorded in Odyssey using data from NASA has apparently confirmed that Odysseus returned to Ithaca on 25th of October 1207 BC(r).

Scholars have generally supported the idea that Homer’s works have a Mediterranean backdrop with regular attempts to reconcile his geography with modern locations, such as the claim in 2005 by Robert Brittlestone, a British investigator to have located the site of Ithaca, the homeland of Odysseus, on the Greek island of Cephalonia. This popular idea should be put alongside the views of Zlatko Mandzuka who maintains[1396] that all the locations mentioned in the Odyssey can be identified in the Adriatic.

Nevertheless, there has been a growing body of opinion that insists that this Mediterranean identification is impossible. A range of alternative regions has been proposed(f) as the setting for the epics, which extend from Portugal as far northward as the Baltic.

In his Odyssey (VII: 80), Homer wrote about the island of Scheria in the western sea. His description of the island has been compared with Plato’s description of Atlantis and has led to the theory that they refer to the same place. There is little doubt that both the detailed geography and climatic descriptions given by Homer cannot be easily reconciled with that of the Mediterranean. Consequently, the Odyssey has had many interpretations, ranging from Tim Severin’s conclusion[392] that it refers entirely to the Eastern Mediterranean to Iman Wilkens’ book, Where Troy Once Stood[610], that has the voyage include the west coast of Africa, then across to the West Indies and following the Gulf Stream returns to Troy which he locates in Britain.

Location is not a problem exclusive to the writings of Plato. Wilkins claims are a reflection of similar ideas expressed by Théophile Cailleux[393] in the 19th century. Gilbert Pillot has also argued for voyages of Ulysses having taken him into the North Atlantic[742]. A Spanish review of Pillot’s book is available(ag). In 1973, Ernst Gideon (? – 1975) wrote in a similar vein in Homerus Zanger der Kelten, reprinted later as Troje Lag in Engelan[1643].

It is worth noting that Bernard Jones has recently moved [1638] Troy to Britain, probably in the vicinity of Cambridge, a location also preferred by Wilkens! Like many others he argues that Homer’s Iliad and Odyssey were not set in the Mediterranean as so many of the details that he provides are incompatible with the characteristics of that sea. However, Jones has gone further and claimed that there are details in Virgil’s Aeneid, which are equally inconsistent with the Mediterranean [p.6-10], requiring a new location!

An interesting overview of the various attempts to transfer the Odyssey from the Mediterranean to Northern Europe is available(w). Damien Mackey has also endorsed the idea of a Northern European backdrop to Homer’s Odyssey(aa).

Another researcher who places all of Odysseus’ travels in the eastern Atlantic is Gerard. W.J. Janssen of Leiden University on the website(v).

The idea of an Atlantic backdrop to the Homeric epics will not go away. The Dutch researcher, N.R. De Graaf(ae). continues to write extensively on his Homeros Explorations website(ad)(x) regarding many of the specifics in Homer’s accounts. He has proposed Lanzarote in the Canaries as the location of Scheria, which concurs with the views of Wilkens and Janssen. Other specifics are that Ithaca was near Cadiz and that the Sparta was Cordoba, while the ancient city of Carmona on the plains of Andalucia are, for De Graaf, Mycenae!(af)

E.J. de Meester also argued(ac) for the British Isles as the location of many of Homer’s references. It struck me as quite remarkable that the level of debate regarding the date, source and geographical details of Homer’s works is rather similar to the controversy surrounding Plato’s Atlantis in Timaeus and Critias. The late Edo Nyland was another researcher who had also opted for a Scottish backdrop to the Odyssey and had recently published his views[394].

Felice Vinci also supports[019] a Northern European background to the Iliad and Odyssey. However, in Vinci’s case, Scandinavia, and in particular the Baltic Sea, is identified as the location for the adventures in Homer’s classic. An English language synopsis of his book is available on the Internet. The persuasiveness of Vinci’s argument has recently renewed interest in the idea of a Baltic Atlantis. The assumption being that if Troy could be located in the Baltic, so might Atlantis. Vinci’s views are comparable with those of J. Rendel Harris expressed in a lecture delivered in 1924(p)  in which he claims that we are entitled to take Homer and his Odysseus out of the Mediterranean or the Black Sea, and to allow them excursions into Northern latitudes.

However, a scathing review of Vinci’s book can be found on the Internet(d) and in issue 216 (2006) of Fortean Times written by Marinus Anthony van der Sluijs.

Further support for a Northern European Troy has come from the historian Edward Furlong, a former naval navigation officer, who has advocated for over twenty years that the journey of Odysseus went as far north as Norway. His particular views are outlined on the Internet(c) .

Other writers, such as the late Henrietta Mertz [0396/7], have suggested that Homer’s epic refers to a trip to North America. Professor Enrico Mattievich Kucich of Lima University is also certain that the ancient Greeks discovered America America[400]. However revolutionary this idea may seem it shows how this particular subject is growing and would probably justify a reference book of its own.

The idea of an Atlantic backdrop to the Homeric epics will not go away. The Dutch researcher, N.R. De Graaf, continues to write extensively on his Homeros Explorations website(x) regarding many of the specifics in Homer’s accounts.

In 1973, James Bailey proposed in his well-received The God-Kings and the Titans[149] that the Odysseus recorded a trans-Atlantic trip. Evidence exists for large-scale mining in the Americas as early of the 5th millennium BC. Bailey maintained that the Europeans imported enormous quantities of copper and tin from Central and South America to feed the demands of the Old World Bronze Age, an idea that was later heavily promoted by Frank Joseph and in great, if overly speculative, detail by Reinoud de Jong(y).

Finally, the Atlantis connection with this entry is that if, as now appears to be at least a possibility, Homer’s Odyssey was about a journey to the North Sea then the possibility of a North Sea setting for the Atlantis story is somewhat reinforced.

A recent book[395] by Steven Sora has developed the Atlantic notion further with the suggestion that not only was Troy located outside the Strait of Gibraltar but that both Homer’s Trojan war and Plato’s Atlantean war are two versions of the same war with the understandable distortions and embellishments that can occur with a narrative, probably involving some degree of oral transmission and then written down hundreds of years after the events concerned.

Ukraine is soon to be added to the growing list of alternative locations for the setting of Homer’s epics with the publication of Homer, The Immanent Biography, a book by A.I. Zolotukhin(g). He claims that Homer was born in Alibant (Mykolayiv, Ukraine) on September 14, 657 BC(t). He follows the views of Karl Ernst von Baer (1792-1876) who believed that most of Odysseus’s travels took place in the Black Sea rather than the Mediterranean. Additionally, he locates Atlantis in the western Crimean area of Evpatoria(l). His 60-page book is available on his website(m).

An interesting paper(e) by the German historian, Armin Wolf, relates how his research over 40 years unearthed 80 theories on the geography of the Odyssey, of which around 30 were accompanied by maps. One of the earliest maps of the travels of Odysseus was produced by Abraham Ortelius in 1597(u) , in which the adventures of Odysseus all take place within the Central and Eastern Mediterranean, arguably reflecting the maritime limits of Greek experience at the time of Homer or his sources! Another website(z) by Jonathan S. Burgess, Professor of Classics at the University of Toronto offers further information on this, including some informative bibliographical material.

In 2009, Wolf published, Homers Reise: Auf den Spuren des Odysseus[669] a German language book that expands on the subject, also locating all the travels of Odysseus within Central and Eastern Mediterranean.

Wolf’s ideas were enthusiastically adopted by Wolfgang Geisthövel in his Homer’s Mediterranean[1578], who also concurs with the opinion of J.V. Luce [1579], who proposed that Homer was “describing fictional events against authentic backgrounds.” This would be comparable to a James Bond movie, which has an invented storyline set in actual exotic locations around the world.

Perhaps the most radical suggestion has come from the Italian writer, Michele Manher, who has proposed(h) that Homer’s Iliad originated in India where elements of it can be identified in the Mahabharata!

In August 2015, a fifteen hour reading of the Iliad was performed in London.

Younger Dryas

Younger Dryas 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 temperatures dropped and they began to advance again. The cause of this cooling is not absolutely clear. One view is that a sudden release into the North Atlantic of vast quantities of fresh water 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.

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 in an article on the Ancient Origins website(k).

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!<

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 arrived at the conclusion 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).

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.

Recent discoveries in northern Sudan of dozens of skeletons, the majority of whom were apparently 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)

Hagemeister, Ekatherine F.

Ekatherine F. Hagemeister (1898-1958) was an Estonian scientist, who wrote an article[356] in 1955 in Priroda, the journal of the Soviet Academy of Sciences, following a study of the disintegration of ionium at various depths in the Atlantic and concluded that the Gulf Stream only began functioning around 10,000 BC, coincident with the ending of the last Ice Age which was the apparent time, according to Plato, of the submergence of Atlantis, which Hagwmeister located in the vicinity of the Azores.

Hull, Edward

Edward Hull (1829-1917) was a famous Irish geologist who worked for the British Geological Survey for 41 years until 1891. He was Director of the Geological Survey ofhull Ireland from 1868 and Professor at the Dublin Royal College of Sciences. He published his memoirs in 1910[406].

Hull identified the Azores as possible remnants of Atlantis following the rising of sea levels around 9000 or 10000 BC. He commented(b) “The tradition of Atlantis ‘beyond the Pillars of Hercules’ can scarcely be supposed to have originated in the mind of man without a basis of reality”.

Hull believed that Atlantis in the Atlantic deflected the Gulf Stream leading to the onset of the last Ice Age! It was over half a century before the idea was revived by other researchers such as Tomas and Muck.

In 1890 he drew a famous time chart some fifteen feet long, based on the 1650 biblical dating system[1681] of another Irishman, Dublin-born James Ussher, Church of Ireland Archbishop of Armagh (1625-1656). What is strange about this is that while Ussher dated the beginning of the world to 4004 BC, Hull’s own writings were based on more scientific data. This same chart has been republished more recently by Barnes & Noble(c) and updated in a manner that has horrified creationists.

*However, it should be noted that Sebastian C. Adams (1825-1898) published a comparable wall chart in 1871(a), so it appears that the original concept was Adams’.

The Secret of Atlantis

The Secret of Atlantis [098], by Otto Heinrich Muck (1892-1956), was published posthumously, in German, in 1976, followed two years later by an English translation by Fred Bradley.
muckMuck was a resolute proponent of the theory that Atlantis existed in the Caribbean and was destroyed following an encounter with an asteroid. He identifies two large submarine holes near Puerto Rico as being possibly caused by the primary impact and adds the existence of the Carolina Bays as a possible secondary result.
He goes further and declares that this event took place at 8pm on June 5th, 8498 BC. He has arrived at this specific date following a close study of the Mayan calendar and in particular the presumed starting date of the so-called ‘Long Count’. As Zhirov pointed out ‘this means that one hypothesis is built on another”.

Muck contends, that prior to this collision, the glaciation of Europe would not have occurred as it did, had the Gulf Stream been able to operate as it does today. However, he postulates that a large island had existed in the Atlantic that prevented this from happening but it was destroyed by his suggested impact date of 8498 BC. This gave us the Gulf Stream circulation we now know and raised the temperatures in the north Western Europe. It is worth considering that scientists today are predicting the possibility of the warm Gulf Stream shutting down again due to the rapid melting of the Greenland Ice Cap, ironically as a consequence of global warming. The possible consequences of such an event would be catastrophic for parts of North-Western Europe.

Muck also attempted to bolster his destroyed Atlantic island theory with an explanation for the enigmatic migration habits of European eels.

Overall, this is an interesting, if flawed, work. Any criticism today should be tempered by the fact that was written without the benefit of the discoveries of the forty years since its publication. In that brief time span at least three of the mainstays of his theory, the Gulf Stream, the eel enigma and the Carolina bays have been potentially undermined with alternative explanations.

Egerton Sykes suspected that the impact theories of Muck were founded on those of Frank A. Melton and William Schriever of the University of Oklahoma and William F. Prouty all of whom proposed an extraterrestrial intrusion as the cause of the Carolina Bays.


The Deglaciation that occurred at the end of the last Ice Age has attracted a lot of attention from Atlantis seekers because it coincides with Plato’s apparent date for the destruction of Atlantis and provides us with a possible source of the flood that subsequently not only wiped out the Atlanteans but possibly also the Athenians. However, meltwater from deglaciation causes global sea levels to rise very, very, slowly and so is extremely unlikely to have caused the destruction of the Atlanteans or Athenians as described by Plato.

The melting of the ice caps gradually caused the ocean levels to rise over a period of thousands of years and at times the retreat of the glaciers was halted and occasionally reversed. Although the melting of the ice was relatively steady, the water produced did not always reach the sea in a steady flow. Instead, it was frequently punctuated by enormous discharges of water particularly where ice dams had retained vast melt water lakes.

In the 1920’s a maverick geologist, J Harlen Bretz (1882-1981), postulated that a huge ice-age flood had harlen Bretzcarved the landscape of Eastern Washington state, in just a few days. In spite of acrimonious opposition from the geology establishment of the day, Bretz persevered with his investigations, which eventually led to the identification of Lake Missoula as the probable culprit. Bretz was finally vindicated in 1979 when, in his nineties, he was awarded the prestigious Penrose Medal for his work(f). There is a beautifully illustrated National Geographic online article that reviews Bretz’s work(i).

These discharges of huge quantities of water are recognisable as relatively sudden spikes in the rate of sea level increases and are referred to as Melt Water Pulses WMP).                  

Lake Missoula in what is today the state of Montana is one of the best studied of these glacial lakes. The regular discharges from Lake Missoula, following ice dam collapses, were responsible for the creation of the dramatic Scablands of the North-Western United States. Studies have revealed that between forty and eighty such floods were released from Lake Missoula alone.

However, an alternative to Lake Missoula as the cause of the scablands has been recently proposed(g), namely, the younger-dryas comet impact event. This event was highlighted by Richard Firestone and his colleagues in The Cycle of Cosmic Catastrophes[0110]. My problem with the idea of the comet impact is that it was a single event, whereas the Missoula discharges were according to some authorities quite numerous!

Lake Missoula and its flood path

Lake Missoula and its flood path

The power of fast flowing water was recently highlighted by a report published(c) in the journal of America’s National Academy of Sciences, where a study of Iceland’s unpronounceable Jokulsargljufur canyon indicated that this huge feature was created in a matter of days. In Iceland, such glacial outburst floods are known as Jökulhlaups(d).

It has now been estimated by scientists that around 6200 BC the ancient glacial Lakes Agassiz and Ojibway discharged into the Atlantic Ocean. These lakes were more than twice the size of the Caspian Sea and on their own are estimated to have raised sea levels by up to 4 feet. The freshwater flow is calculated at between 25 and 50 times the flow of the Amazon River and recent studies suggest that this sudden inflow of fresh water brought the Gulf Stream to a halt for more than a hundred years. A 2016 report(e) from CAGE (Center for Arctic Gas Hydrate, Climate and Environment) suggests that the Gulf Stream was not interrupted during the Ice Age.

*Graham Hancock, in his Magicians of the Gods [1119], reviews, at length, the theories of J Harlen Bretz and after a shared field trip and lengthy discussions with Randall Carlson, concluded that Bretz had probably only revealed part of the Scablands story. Hancock has pointed out that Bretz was unaware of the cometary impact identified by Richard Firestone et al., which coincided with the start of the Younger Dryas  period 12,800 years ago. This impact theory continues to amass confirmatory data, but opposition has not abated yet. The cometary impact, the creation of the Scablands and the start of the Younger Dryas cooling period all seem to coincide temporally to a degree that strongly suggests an interconnection.*

Nick Thom has suggested[776] that an even more dramatic consequence of the discharge from Lake Agassiz was the tilting of the Earth’s axis leading to the biblical Deluge and recorded around the world in hundreds of flood myths!

Similar melt water lakes across Northern Europe retained by ice dams produced equally dramatic discharges as the dams periodically broke. One of these occupied what is now the Baltic Sea and was 30 metres above the then ocean level before bursting into the North Sea around 10,000 BC. Less well known is the flooding that took place further east resulting in the creation of a vast inland sea of which the Black and Caspian Seas were just a small part. Ronnie Gallagher has written a revealing paper on the subject(a).

It is worth noting that, although on a smaller scale, two thirds of the thousands of Himalayan glaciers contain glacial lakes, which because of global warming today are growing at risk of bursting with consequent catastrophic results. As these glaciers retreat, apart from the damage to people and property the discharges will gradually reduce the downstream flow of water to rivers such as the Ganges.

Concurrent, with these huge melt water lake discharges were Heinrich Events, named after lake_agassiz_big

paleoclimatologist, Hartmut Heinrich, who as recently as 1988 published evidence that there had been at least six massive discharges of icebergs from the Laurentide Ice Sheet during the last Ice Age. These discharges could have contained millions of cubic kilometres of ice and must have caused substantial sea level rises. This Laurentide Ice Sheet was an enormous mass of ice that stretched from the Arctic through eastern Canada to the northern half of the United States that covered over 5 million square miles. The weight of this ice sheet was so great that it has been calculated that it depressed the earth’s crust by nearly half a mile. A recent paper contends that it was the collapse of this ice sheet, 8000 years ago causing a sea level rise that led to the breaching of a ridge damming the Bosporus and the inundation of the then freshwater Black Sea, which flooded over 73,000 square km of land.

In the southern hemisphere it was discovered a few years ago (Science, Dec.22, 2000) that the River Amazon had experienced a doubling of its outflow between 9800 BC and 9700 BC, probably as a consequence of the melting of Andean glaciers and perhaps increased rainfall during this period. The dates proposed are very close to the 9600 BC date provided by Plato for the submergence of Atlantis.

All these worldwide discharges must have resulted in the inundation of low-lying landmasses, such as the Celtic Shelf or Sundaland, in fits and starts forcing the inhabitants of these regions to regularly migrate to higher ground.

Since it is reasonable to assume that a large percentage of human settlements were then, as now, located along coasts, particularly at river mouths, the consequence for these embryonic cultures must have been catastrophic. It is very easy to see how legends of sunken civilisations probably have a very sound basis in fact. Two books by Graham Hancock[274] and Stephen Oppenheimer[004] have covered this idea in greater detail, lending credibility to the idea of a sunken island such as Atlantis.

However, it can be reasonably argued that the effects of deglaciation are not what Plato described. He spoke of earthquake and a flood that overwhelmed both the Athenians and the Atlanteans. This would more closely match the aftermath of a large seismic or tectonic event that generated enormous tsunamis rather than the gradual rising of sea levels, which even at its most dramatic could never have produced the effect of sinking Atlantis overnight.

However, the waters of tsunamis eventually flow back to the sea, but Plato’s account describes the event resulting in the creation of muddy shallows. To me it sounds more like liquefaction which occurs in soil with particular characteristics when subjected to an earthquake(b), similar to the destruction of the cities of Canopus and Herakleion near Alexandria.

A website that graphically illustrates the process of deglaciation after the last Ice Age is available(h).

Muck, Otto


Otto Heinrich Muck (1892-1956) was born in Vienna and graduated as an engineer at the Munich College of Advanced Technology. Muck had a very productive life that saw him hold patents for around 2000 inventions at the time of his death. During World War I, he was a flying officer and during World War II, he invented the U-boat schnorkel and was also a member of the Peenemunde Rocket Research Team. After the war Muck was a scientific consultant to large industrial concerns. He died in 1956 following an accident.

Muck published his worthwhile contribution to the Atlantis mystery, in German, Alles über Atlantis[1468], in 1954. It was translated into English by Fred Bradley and published in Britain in 1978[098]. The book was well received and his views continue to have support today.

Muck’s book is now out of print, but English translations of  it can now be viewed and downloaded from the Internet(a).

Muck believed that Atlantis had been located on the Mid Atlantic Ridge and was destroyed as a consequence of an asteroidal impact. He maintained that the asteroid hit the Atlantic, east of the Caribbean, creating the remarkable Carolina Bays en route with its attendant debris and causing tectonic disturbance of such a magnitude that it led to the sinking of Atlantis. He considered the Azores to be remnants of Atlantis.

Muck attributes many of our flood myths to the ensuing tsunamis. With Teutonic precision he pinpoints the time and date of this disaster to 8.00pm on June 5th, 8498 BC, but carelessly omits to tell us whether this is Greenwich Mean Time, Central European Time or some other zone.

Muck’s impact theory would appear to have been ‘inspired’ by the studies of two American geologists, F.A. Melton and W. Schriever in the early 1930’s and the later work by W.F. Prouty(a).

However, I must point out that when an aerial survey was carried out in the 1931, when the number of ‘bays’ was counted at 3,000. Muck estimated that the bombardment was even greater off the coast, with as many as 7,000 more hits in the ocean. So based on this total of 10,000 Muck proceeded to calculate the mass of the asteroid. Now that we know that the bays on land may number as many as half a million, Muck’s estimations need serious revision. 

Muck MapMuck identified what he considered to be two huge impact craters in the Atlantic east of Puerto Rico as evidence of the catastrophe that led to the destruction of Atlantis. Unfortunately for Muck supporters, improved satellite imagery since the 1970’s has shown these ‘craters’ to be chimeras(c).

He further contended that prior to the destruction of Atlantis in the Atlantic the Gulf Stream had been blocked and that after the catastrophe it had pushed northward improving the climate of the British Isles and northwest Europe. In this regard he was following the views of René Malaise.> A German article(b) by Dr. Gerhard Kühn, in 2016, has offered some support for Muck’s suggestion that the Gulf Stream had been deflected by a large island in the Atlantic before the end of the last Ice Age.<While in the same year, another report(d) proposed that the Gulf Stream had not been interrupted during the last Ice Age!

Understandably, half a century later, advances in various scientific disciplines have demonstrated flaws in his theories. Nevertheless a number of researchers, such as Wolter Smit, Dale Drinnon, Roland Horn and Prescott Rawlings still support aspects of Muck’s theories. More recently, Andrew Collins has adopted Muck’s Atlantic impact theory in his Atlantis in the Caribbean[1197].

However, Muck’s book is still worth reading as a study in theory building. Used copies can (Feb. 2013) be had very cheaply (€0.01) through Amazon.

Over twenty years after his death, another book commenced by Muck was published as: Geburt der Kontinente (Birth of the continents)[1100], completed by F. Wackers and edited by Mario Muck and Ferdinand Wackers.
