They have promoted what became known as ‘Coherent Catastrophism’, which envisions encounters between our Earth and large comets, events that are recorded in ancient history and mythology. They claim, for example, that the biblical Exodus story contains an early reference to Halley’s Comet! Among other encounters, they date the story of Phaëton, mentioned by Plato, to 1369 BC and also discuss catastrophic close encounters with Encke’s Comet or a proto-Encke.
Although Clube & Napier do not refer to Atlantis, from time to time, some commentators have claimed some connection between the demise of Atlantis and encounters with comets named and unnamed.
Philip R. “Pib” Burns has an excellent overview(a) of Clube and Napier’s work on his excellent website.
Charles A. Rogers is the author of a fully illustrated paper(a) in which he locates the city of Atlantis on the Tunisian River Triton, which led from Chott el Jerid (formerly Lake Tritonis?) to the Gulf of Gabes. He dates the demise of Atlantis to 1404 BC based on a possible connection with a close encounter with Phäeton, which in turn he identifies as what was later to be known as Halley’s Comet. He also combines all this with the eruption of Thera that generated a tsunami, which ran across the Mediterranean to the Gulf of Gabes and destroyed the city of Atlantis and in Egypt wiped out the Pharoah and his men during the biblical Exodus. There seems to be too many coincidences required here.
With regard to the location of Atlantis, the satellite imagery used by Rogers is, in my view, not very convincing and although I am sympathetic to the existence of Atlantis in that region, I think only investigation on the ground will offer real evidence.
J. Fitzgerald Lee was the controversial author of The Great Migration, who proposed that the Israelite migration recorded in Exodus was not from Egypt to Palestine, but from Central America westward, via the frozen Bering Strait, through Asia and on to Europe and Egypt! He also speculated that Atlantis had existed in the Atlantic and that its submergence cut off Africa from Central and South America(a).
Late Bronze Age Collapse of civilisations in the Eastern Mediterranean in the second half of the 2nd millennium BC has been variously attributed to earthquakes, volcanic eruptions and severe climate change. It is extremely unlikely that all these occurred around the same time through coincidence. Unfortunately, it is not clear to what extent these events were interrelated. As I see it, political upheavals do not lead to earthquakes, volcanic eruptions or drought and so can be safely viewed as an effect rather than a cause. Similarly, climate change is just as unlikely to have caused eruptions or seismic activity and so can also be classified as an effect. Consequently, we are left with earthquakes and volcanoes as the prime suspects for the catastrophic turmoil that took place in the Middle East between the 15th and 12th centuries BC. Nevertheless, August 2013 saw further evidence published which blamed climate change for demise of civilisations in the region.
Robert Drews dismisses any suggestion that Greece suffered a critical drought around 1200 BC, citing the absence of any supporting reference by Homer or Hesiod as evidence. He proposes that “the transition from chariot to infantry warfare as the primary cause of the Great Kingdoms’ downfall.”
This extended period of chaos began around 1450 BC when the eruptions on Thera took place. These caused the well-documented devastation in the region including the ending of the Minoan civilisation and probably the Exodus of the Bible and the Plagues of Egypt as well. According to the Parian Marble, the Flood of Deucalion probably took place around the same time.
Professor Stavros Papamarinopoulos has written of the ‘seismic storm’ that beset the Eastern Mediterranean between 1225 and 1175 BC(a). Similar ideas have been expressed by Amos Nur & Eric H.Cline(b)(c). The invasion of the Sea Peoples recorded by the Egyptians, and parts of Plato’s Atlantis story all appear to have taken place around this period. Plato refers to a spring on the Athenian acropolis (Crit.112d) that was destroyed during an earthquake. Rainer Kühne notes that this spring only existed for about 25 years but was rediscovered by the Swedish archaeologist, Oscar Broneer, who excavated there from 1959 to 1967. The destruction of the spring and barracks, by an earthquake, was confirmed as having occurring at the end of the 12th century BC.
(this is a shorter version of (c) below)
Nibiru was a Sumerian astronomical term used to describe a planetary body that periodically approached Earth. This account was hijacked by the late Zechariah Sitchin to construct his Planet X theory in which he claimed that this planet had an orbit which took it to the outer limits of the solar system returning every 3600 years to the vicinity of Earth. Sitchin claimed that during one of these visits some of its inhabitants came to earth and become the ‘gods’ of the Sumerians. However, Sitchin failed to explain how the inhabitants of this Planet X survived the lack of heat and light that it would have had to endure as it moved away from the proximity of the Sun. For us inhabitants of Earth a drop of just a few degrees is fatal.
However, Emilio Spedicato has a radically different and certainly more rational view of this Sumerian planet. He ascribes a much shorter orbital period of 20 years to Nibiru and claims that close encounters with this planet (and its satellites) had a dramatic physical effect on the prehistory of our planet including the capturing of our Moon, the destruction of Atlantis and later the biblical Exodus! His scenario has elements that can be traced to Velikovsky, Ackerman and Hörbiger.
>Robert Solarion was a keen follower of Immanuel Velikovsky and like him was conviced that in the first and second millennia BC the Earth had suffered a catastrophic Pole Shift as a result of a close flybys of a large extraterrestrial body or bodies. Velikovsky identified these as Venus and Mars, but Solarion differed, suggesting that it was the putative Nibiru!(h)<
Professor Spedicato’s November 2012 paper, From Nibiru to Tiamat, an Astronomic Scenario for Earliest Sumerian Cosmology, can be read or downloaded from the excellent Diffusion and Migration website(a). A number of his other papers can be found on the same website and are certainly worth studying.
In sharp contrast to the serious work of Spedicato, for the past couple of years we have been subjected to a barrage of silly articles(b) linking Nibiru with the promised 2012 global catastrophes ‘predicted’ by the Mayan calendar.
A debunking of both Sitchin’s scholarship and the existence of Nibiru has been offered by a number of sites(c).
However, some people, such as David Meade (a pen-name) who describes himself as a ‘Christian numerologist’ predicted that Nibiru would collide with Earth on September 23, 2017! When this did not happen he moved the event to October, but again nothing happened. But he persisted and subsequently moved our demise to March 2018, then April, with a final suggestion for the year of between May and December(d).
Emilio Spedicato (1945- ) was born in Milan. He graduated in physics and is now working in numerical analysis and applied mathematics. He has held a full professorship at Bergamo University since 1984. In addition to his more conventional academic pursuits, he also researches ‘non-standard models of planetary evolution and non-standard interpretation of myth and ancient religions.’
Spedicato has developed a list(a) of ‘54 theses for reconstructing Earth and human history during the catastrophic period 9500 to 700 BC’. This list is partly based on the work of Velikovsky, DeGrazia and Ackerman and is intended to be the basis of a larger work in book form. Some of his ideas will be seen as highly controversial such as the genetic manipulation of humans by extraterrestrial visitors. He locates the Garden of Eden and the ‘creation’ of Adam and Eve in the Hunza valley of modern Pakistan(e).
He ventured into further controversial territory with his support for an updated version of Hörbiger’s moon capture theory(f) and endorsement for pole shifts(g) after long periods of stability following encounters with large extraterrestrial bodies. He considers the last of these to have taken place in the 10th millennium BC.
Spedicato, in a series of papers delivered to the Atlantis Conference on Melos in 2005, linked the biblical Exodus with the Flood of Deucalion, which he dates as 1447 BC(d). He contended that these events were connected with the explosion of a large extraterrestrial body over Southern Denmark remembered in Greek tradition as Phaëton.
Atlantis has not escaped Spedicato’s attention and he has put forward the Caribbean island of Hispaniola as the home of Atlantis(b), specifically suggesting that Lake Enriquillo in the Cul-de-Sac Depression, which runs from Haiti across the border into the Dominican Republic. Spedicato accepts the possibility of the destruction of Atlantis around 9600 BC and has written an interesting paper(c) that links the demise of Atlantis with a direct asteroidal impact or a close encounter with a planet-sized body. Not without significance is the fact that Hispaniola is not submerged, in spite of the sea level rising hundreds of feet since the very early date proposed by Spedicato for the destruction of Atlantis, which should have sent it even deeper beneath the waves of the Caribbean.
Furthermore, leaving aside the question of submergence altogether, Spedicato does not explain how an Atlantis in the Caribbean could, in 9600 BC, have attacked Greece or Egypt, which did not exist as structured societies at that time.
Even more intriguing is why they would plan such a venture, considering a distance of 10,000 kilometers lay between them.
Spedicato has contributed at least a dozen papers to the Migration and Diffusion website including one on a possible Indian inspiration behind the Giza pyramid complex(h) as well as a paper(i) on the planet known to the Sumerians as Nibiru and today sometimes referred to as Planet X. He controversially claims that a close encounter with Nibiru around 9500 BC ended the last Ice Age and brought about the demise of Atlantis! A difficulty with that idea, is that if the encounter with Nibiru destroyed Atlantis AND ended the Ice Age how could the location where Atlantis was submerged still be marked by mud shoals 9,000 years later when sea levels had risen by 300-400 feet, as confirmed by Plato in Timeaus 25d?
*Another radical idea put forward by Spedicato was expressed in a paper delivered to the 2005 Atlantis Conference [629.411], in which he claimed that what he called ‘the ancestors of the Greeks’ had visited Canada. Based on his interpretation of excerpts from the writings of Plutarch, he specifies a region at the mouth of the St. Lawrence River as the point of contact. Manolis Koutlis goes further, suggesting that the Greeks had colonies there from 1500 BC until 1500 AD. Then in his book In the Shadow  he adds the even more extraordinary claim that Atlantis had been situated on an island at the entrance to the St. Lawrence!*
In 2010, Spedicato published Atlantide e L’Esodo (Atlantis and Exodus) which is currently being translated into English.
In February 2015 Spedicato published another paper(j) with the radical proposal that the alignment of the three main Giza pyramids was not intended to be a reflection of the three stars in Orion’s belt, as proposed by Gilbert & Bauval, but instead were more closely matched to the arrangement of three volcanoes on Mars! He claims that these volcanoes were visible from Earth during Mars periodic close encounters with our planet between 7000 BC and 700 BC, during a 54-year cycle.
Later in 2015 the prolific Spedicato published another paper(k) in which he linked Mayan catastrophes with those of Hesiod, Plato and the Bible.
The Biblical Exodus has been linked by some with the time of the destruction of Atlantis. J. G. Bennett has firmly identified the 2nd millennium BC eruption of Thera with the destruction of Atlantis(f) and in turn the effect of the volcanic fallout on the Egyptian nation generating the Plagues of Egypt recorded in Exodus.
Dr. Hans Goedicke, a leading Austrian Egyptologist, expressed a similar view regarding an Exodus link in a 1981 lecture, leading to quite a media stir(c). Ian Wilson, best known for The Turin Shroud, has calculated that the volcanic plume from the Theran eruption would have been clearly visible from the Nile Delta[979.112].
Riaan Booysen believes(b) that there were two Exodus events that can be linked with three possible Theran eruptions and has identified the Israelites as the Hyksos. Ralph Ellis has also linked the biblical Exodus with the expulsios of the Hyksos and devoted a short book to the idea.
Immanuel Velikovsky and others believed that the controversial Ipuwer Papyrus provides evidence in support of the biblical Exodus as well as the ‘Plagues of Egypt’(d).
Emilio Spedicato links the biblical Exodus with the explosion of Phaëton in 1447 BC, without any reference to the destruction of Atlantis, which, based on his interpretation of Plato’s text, he associates with a much earlier catastrophe(a).
Alfred de Grazia offers a radical interpretation of the Exodus in God’s Fire , in which he saw the Exodus as a highly organised, rather than an opportunistic event. He also attributed some level of electrical knowledge to Moses, whom he credits with the construction of the Ark of the Covenant, if not the ‘invention’ of Yahweh himself!
Perhaps the most extreme Exodus theory has been presented if by Finkelstein & Silberman, who have claimed that “the saga of Israel’s Exodus from Egypt is neither historical truth nor literary fiction” [280.70]. However, the same disbelieving Finkelstein is now going on a search for the Ark of the Covenant(e) !
Flavio Barbiero has now produced an extensive paper(g) in which he precisely dates the Exodus to the night between the 14th and 15th of July of 1208 B.C. (2/3 July of today).
Flood of Deucalion is recorded in Greek mythology in terms that are reminiscent of the biblical Deluge. Prometheus the brother of Atlas the Titan, warned his own son Deucalion to build an ark and fill it with all he needed. Rain fell ceaselessly, flooding valleys, submerging cities, destroying all people and leaving just some mountain peaks to be seen above the sea. After nine days the rain stopped and Deucalion and his wife Pyrrha emerged and produced the ancestors of the Greeks.
Ogyges was the founder and king of Thebes whose reign was ended by a flood that covered the whole world and so devastated Thebes that it remained without a king until the reign of Cecrops. It is an open question whether the Flood of Deucalion and the Flood of Ogyges are identical or not.
J. G. Bennett has pointed out(a) that a fractured marble pillar, discovered on the Greek island of Paros and known as the Parian Marble, records important events in early Greek history including lists of the early kings, including Deucalion who is noted to have reigned at the same time as the Egyptian Pharaoh Thutmose III (1504-1450 BC). It records his reign as having been 700 years before the first Olympiad, which itself is dated to 778 BC, thus giving a date for the flood named after him to around 1478 BC, This period coincides with the biblical Exodus and the eruption of Santorini. Orosius, a 5thcentury AD writer, placed the Flood of Deucalion 810 years before the foundation of Rome giving it a date broadly around 1500 BC. This is suspiciously close to the date accepted by most archaeologists for the great eruption of Thera. James Mavor supported a date between 1529 and 1382 BC.
Giovanni Rinaldo Carli quotes from Clement of Alexandria (150-215 AD) who notes that Stenelas (Sthenelus), father of Cydas (Cycnus) the king of the Ligurians, lived at the same time as the fire of Phaëton and the Flood of Deucalion. This is probably one of the earliest references suggesting a linkage between these two catastrophic 2nd millennium BC events.
Emilio Spedicato has also linked the Flood of Deucalion with the Exodus and dates them to 1447 BC. However, he believes that these events followed the explosion of a comet or asteroid over southern Denmark. He presented three papers to the 2005 Atlantis Conference on the subject of Deucalion’s Flood and Phaeton[629.115].
The work of Finkelstein and Silberman has recently cast doubts over the historical reality of the Exodus, but of course this does not affect the reality of the Flood of Deucalion.*[It is odd that with such a sceptical view of Bible history that it was announced in February 2017(b) that Finkelstein is to start a search for the Ark of the Covenant.]*
David Rohl, a leading advocate for a drastic revision downwards of the dates of many events in ancient Egyptian history by at least three hundred years, has concluded that Deucalion’s Flood occurred during the reign of Thutmose III and most controversially that it was concurrent with the eruption of Thera and its consequent tsunami. According to Rohl’s ‘New Chronology’, this would give the Flood a date of around 1100 BC rather than the conventionally accepted date of around 1450 BC.
Over the last couple of millennia there has been a general consensus that the Flood of Deucalion occurred in the middle of the second millennium BC. This leaves supporters of an early date for Atlantis obliged to produce evidence of a comparable catastrophe around 9600 BC, a task compounded by the probable erosion of any such evidence during the passage of such a considerable time span. We can expect this particular debate to run for some time yet.
Riaan Booysen is a South African researcher (and avid tennis fan) who has written articles on a number of ancient mysteries, which can be found on his website(e). Among his controversial ideas are that the Queen of Sheba, Nefertiti and Helen of Troy were a single person(d).
He offers a major paper on Atlantis(a), in which he bravely identifies its location as an extensive landmass which included present day Australia. Unlike other writers who have offered similar suggestions based on guesswork, Booysen offers a coherent thesis based on the geology of the South Pacific and early cartography.
His theory requires a radical redating of the Antarctic ice cap, which has led to continued debate on the internet(c).
Booysen has published another contentious offering in 2013, entitled Thera and the Exodus in which he argues that there were at least two Theran eruptions which led to two separate ‘Exodus’ events by the biblical Israelites, whom he identifies as the Hyksos!
He dates these events to ca. 1613 & 1450 BC.
Booysen has now commented on negative feedback from his book(b).
A year later he ventured into even more contentious territory with the publication of BARBELO – The Story of Jesus Christ, now available as a free ebook(f).
In 1925 was Bennett was a witness to low level volcanic activity on Santorini, which led him to investigate the possibility many historical events were triggered by volcanic eruptions.
Bennett published an interesting paper(c) in 1963, in which he argued cogently for the linking of the destruction of Minoan Crete, the Biblical Exodus, the Flood of Deucalion as well as the demise of Plato’s Atlantis. A more controversial paper(d) was delivered the same year promoting the idea of a Hyperborean or Arctic origin for the Indo-European culture
