Catastrophes: from Atlantis to the Aegean
Paul Dunbavin (2019)
Summary:
This discussion compares the popular-academic rationalisation of Plato’s Atlantis as a fictional
memory of the Thera-Santorini eruption with the alternative based on a stricter adherence to the
internal evidence of the narratives. It also posits that the ultimate source is Libyan-Egyptian rather
than Greek and that any solution must also comply with the additional semi-historical information
supplied by Diodorus Siculus in his Histories. This is taken together with an analysis of the known
geological and climate events of prehistory as compared to those suggested in the narratives.
The Athens Acropolis and Mount Lycabettus were occupied at least 6,000 years ago during the Greek Neolithic. Picture

Modern commentators who discuss Plato’s Atlantis and its demise will typically fall into two camps.
The first would be the scholars of Greek literature and others that follow their lead, who prefer to
retain the story within the realm of Greek mythology; they would treat it as Plato’s literary fiction
based solely upon his own philosophy and knowledge of the ancient world. Typically such
commentators rationalise Atlantis as a hazy memory of ancient Crete or of the Thera (Santorini)
eruption and tsunami that destroyed the city of Akrotiri on that island. However, this supposition
ignores many internal statements of the narratives and neglects the additional details about Atlantians
given by Diodorus Siculus. The hypothesis has become a regular feature in various much-repeated
television series linking Atlantis and ancient Cretan civilization.
The second group of commentators are the diverse popular enthusiasts, who would seek to locate
the lost city in a variety of places, from the Caribbean to the poles, selecting only those elements
from Plato that they need and discarding the rest. Many of these also neglect Diodorus Siculus.
There is a reasonable third approach: which is to consider Plato’s account for the most-part truthful
and to analyse Atlantis and its catastrophe as a degraded history of ancient events; preserved in Egypt,
and brought back to Greece by the sage Solon in the sixth century BC just as Plato says. Any
proposed solution must therefore respect all the details of the ancient story that we have inherited
from Solon’s Egyptian source: Sonchis of Saïs. It is then possible to compare the legend with Egyptian
rather than Greek tradition; and with the wider tradition of North Africa as I did in Towers of Atlantis
and earlier books. This would transfer tenure of the story away from Greek scholarship to the
Egyptologists – but these specialist-archaeologists don’t want it! They would shy away from being
tainted by speculation about Atlantis.
Those who regard Atlantis as Plato’s fiction seldom look beyond the Thera eruption of c.1625. For
this to work they have to discard the fabulously long chronology supposedly given to Solon by the
Egyptian priest; indeed his estimate of 9,000 years before his own time merely reinforces their
scepticism as there is scant evidence of settlements in Greece from such an early date. Plato’s
timescale therefore has to be reduced by a factor of ten to make it credible. Another argument
employed is that Plato’s references to bronze would mean that Atlantis could not be older than the
Bronze Age. However, as I argued in Towers of Atlantis the date of the Bronze Age itself is constantly
being pushed further back in time by archaeological discoveries and is now set as early as 3200 BC for
the Aegean. Those who wish to pursue the historiography may like to read the classic paper of 1960
by A.G. Gallanopoulos, which discussed the original excavations of Professor Marinatos, along with a
survey of ancient Greek tsunami references that retain their relevance.
The true dating indicators within Plato’s narratives are the statements that Atlantis and its
catastrophe fell before the establishment of the Temple of Neit and its institutions at Saïs in the
Egyptian Delta. In Timaeus the priest puts the foundation of Saïs at 8,000 years before his own time
and that of Athens 1,000 years earlier; in Critias he says that 9,000 years had elapsed. This association
would place the events right at the foundation of Dynastic Egypt, around 3100 BC or during the
earlier predynastic era – and therefore at least 1500 years earlier than the Thera eruption. Those
unfamiliar with the Egyptian goddess Neit may like to read these links:
Neit was a war goddess of probable Libyan origins equivalent to Greek Athene. The religion of Neit
was at its strongest during the First Dynasty after the unification of Upper and Lower Egypt.
Egyptologists find the mastaba tombs of the First Dynasty kings – and also their queens who bore
titles derived from the goddess Neit. It follows logically that if the Temple of Neit was established in
the delta as long ago as the First Dynasty then we cannot set the era of Atlantis, or the catastrophe that
destroyed it, any later than this date. The long-chronology, stated by Sonchis to Solon to derive from
“sacred records”, can then be seen as entirely consistent with the long-reigns of gods and demi-gods
whom the Egyptians believed had ruled the Nile valley prior to the dynasties of mortal kings. [see
Note 1] It is therefore relevant to seek a geological catastrophe that could sink an island or a city
from a time before the establishment of the First Dynasty – the late fourth millennium BC.
A tectonic puzzle! The Mediterranean Sea is a seismically complex region with numerous fault lines, some of which are
ancient and inactive. Shown here, for simplicity, are just the principal active subduction faults or crumple zones together
with the normal faults where sideslip may occur. It is possible that a mega-quake in one region such as the Atlantic could
trigger other events further east along this line of activity.
Another internal detail is that the submergence of the city and its island corresponded with great
earthquakes in Greece that destroyed ancient Athens and its armies – who had just fought-off an
attack by Atlantians from the west. We may ask: what links Greece and the Atlantic Ocean? The
obvious connection is the geological fault that runs from the Azores in mid-Atlantic through the Strait
of Gibraltar, onward to Malta and Sicily in the central Mediterranean and then to the Aegean Sea. The
geologists tell us that this is where the African continental plate is being subducted beneath the vast
Eurasian plate; and the Aegean micro-plate is all that remains of the ancient Tethys Ocean that
separated them. Subduction zones and their volcanoes are the most unstable regions on the planet;
where earthquakes tend to be at their greatest magnitude, but occur only after deceptively long
intervals of apparent stability.
Before we examine the geology, we should also review the parallel chronicle offered by Diodorus
Siculus, who also tells us about Atlantians (a slightly different spelling but clearly related) and who
possessed great cities. He goes-on to describe a matriarchal race called the Amazons, who similarly
worshipped the goddess Neit-Athene; they conquered an Atlantian city named Cernê situated
somewhere along the Libyan (North African) coast. The city of the Libyan Amazons was called
Cherronesus (‘peninsula’) and it lay in the marsh Tritonis; generally identified with low-lying Chotts of
Tunisia, but no-one really knows where it was. At some later time this city too was submerged in a
time of great earthquakes:
“…the marsh Tritonis disappeared from sight in the course of an earthquake, when those parts of it which lay
towards the ocean were torn asunder”. [Note 2]
It is then logical to ask whether this remembers the same geological event that is recalled in the
Atlantis legend. Plato, in Timaeus also says: “later… [there came] earthquakes and floods of extraordinary
violence”. If we treat Atlantis as an Egyptian rather than a Greek history then we have here two
independent accounts, both ultimately of north-African derivation, that recall: Atlantians, the goddess
Neit-Athene, a catastrophic submergence and a great earthquake. Too many coincidences here to just
ignore!
It is sometimes forgotten that we have very few ways of dating ancient earthquakes and volcanic
eruptions unless there is a historical report. For example archaeologists still argue about the true date
of the Thera eruption – some want to place it around 1500 BC; others following carbon-14 and treering dating prefer 1600-1645 BC. For ancient earthquakes we can say even less; even if there is some
artefact to be carbon-dated, the magnitude of an ancient quake can be only subjective specialist
opinion. Some idea of the difficulties can be gained from the significant earthquakes database, [1]
To attempt a dating of the earthquakes recalled by Diodorus is therefore problematic; the specialists
will only trust a firm historical report, whereas the historical investigator wants the geologist to
suggest a date. From the wording we can see that the ancient earthquake was no minor episode;
Diodorus recalls that low-lying regions towards the Ocean were “torn asunder”. This sounds very
much like a mega-quake (magnitude 8.5 or greater) of the kind expected along a subduction zone,
resembling those experienced more recently in Alaska and Chile. Diodorus Siculus or his lost source
could not have known that two thousand years later geologists would discover that the Algerian coast
was a mountain-building subduction zone, in order to invent a ‘mythical’ ancient catastrophe in just
the right location. This kind of coincidence is what I have elsewhere termed a ‘mythological fossil’: an
element within a myth that can be extracted and independently tested by science. Somewhere along
the Mediterranean coast between Tunisia and Morocco there may be two lost cities waiting to be
discovered, but precisely where cannot be discerned from the vague geography of Diodorus! It should
be noted that neither of these lost cities would be Atlantis – that was somewhere else.
To commence at the western-end of the line of faults, in the Atlantic Ocean, we find the islands of the
Azores; for so long naively claimed as the peaks of the sunken continent. We can now see these midocean islands as a volcanic product of the transform fault that links the mid-Atlantic ridge of sea floor
spreading to the subduction zone of Iberia-Africa. The nature of the fault therefore changes around
the region of the Gorringe Ridge to the west of Cape St Vincent, where we find flat-topped
seamounts that were formerly volcanic islands. Reliable evidence, of precisely when they were above
the sea is still unavailable. Where oceanic plates of equal density collide they tend to push-up volcanic
island chains and one day the ridge will become a new peninsula of Iberia.
North Africa
East of the Gorringe Bank the fault splits, with one active branch running north-east across the Sierra
Nevada of southern Spain while the other continues through Morocco. Here we may hope to find
more evidence of ancient earthquakes. Perhaps the various ancient legends surrounding the Pillars of
Heracles do remember a series of real quakes that altered the coastline. The true active fault zone
continues along the North African coast: through Morocco-Algeria-Tunisia. The largest documented
earthquake here was that at magnitude-7, which occurred on 10 October 1980. [2] This is far from
the worst to be expected of a subduction zone and those recorded further east in Tunisia tend to be
of lesser magnitude. [3]
A catalogue of early historical earthquakes in Algeria lists one that occurred in Setif in 419 AD,
magnitude unknown, but severe enough to be recorded. [4] Early historical quakes are recorded in
Tunisia around 412 AD. A specialist dare not, of course, cite the legendary account of Diodorus
Siculus or his lost source Dionysius as ‘evidence’. Presumably Dionysius was citing historical sources
in the Great Library of Alexandria. For comparison, Old Alexandria itself was lost to the sea following
the earthquake and tsunami of 365 AD (estimated magnitude 8.5 off Crete). An account of this
tsunami and its effects are given by the Roman historian Ammianus Marcellinus:
The same tsunami may have been responsible for the inundation of Roman Neapolis in Tunisia. It is
therefore not unreasonable to hold that even older settlements have been lost to ancient quakes
further west along the coast of Africa.
Iberia
The Gorringe Ridge is believed to be the epicentre of the great Lisbon earthquake of 1755 that
destroyed the colonial economy of Portugal, if not quite the city itself. Recent estimates rate the
magnitude as no more than 8.5 – not quite the maximum 9.0 associated with a true subduction zone.
An excellent account of the Lisbon earthquake, leading to numerous references, is given at the
Volcano Café website.
Plato quite clearly locates his lost island and its city in the Atlantic Ocean beyond the Strait of
Gibraltar, but we shall not pursue that thread here. The evidence of Diodorus, from a completely
independent source, would mitigate any suggestion that it was Plato alone who gave the Atlantic
Ocean and its inhabitants a fictional name. Why has conventional scholarship neglected this
corroborating evidence from Diodorus? Perhaps because he offers us mythology derived from
unfashionable African sources, which attempts to rationalise the ‘pure’ Classical myths taught in
schools and universities.
Elsewhere in his histories, Diodorus offers a rationalised summary of the legend of Heracles and his
voyage to the west. This is Heracles the man, not yet the god! The hero’s legendary voyage and
labours were a later event than the war between the Atlantians and the Libyan Amazons. [Note 3] It is
apparent from this narrative that Heracles set up his legendary pillars at what we now know as the
Gibraltar Strait; and his voyages continued further west into the Atlantic, to Gades (modern Cadiz in
Andalucía) and north into Gaul. This independent source contradicts any suggestion that Plato or
Solon did not know where the legendary pillars were situated.
Plato and his source are consistent that the lost city was situated outside the straits and this has led
some commentators to link it with another legendary Bronze Age lost city named Tartessos; believed
to lie beneath the low-lying marshland between Cadiz and Seville, where silver has been mined since
ancient times. A lost city here there may have been, but similar arguments may be advanced against
this identification as apply for Thera and Akrotiri; It fails to meet the Atlantis description both in date
and geography. The Andalusian coast is subject to the same geological influences as were discussed
for the Lisbon earthquake.
The onshore record suggests a major tsunami in the Gulf of Cadiz around 4,000 years ago, with
perhaps as many as eight over the last 7,000 years. [5] We should also consider the effect of tsunamis
created by underwater landslides. These may be triggered at any time by forces not necessarily
associated with major earthquakes. In addition to the 1755 tsunami earlier underwater mud-flows
(turbidites) are dated to 218 BC, 3010–3960 BC and 7765–8065 BC. [6]
It is conceivable that the legendary report of Diodorus recalls an underwater landslide event of the
fourth millennium BC – but to accept an earthquake/tsunami solution here for the Atlantis ‘quake’
would require a mechanism to transmit its effects within the Mediterranean as far as Tunisia and
Greece.
Malta and Sicily
Pivotal within the central Mediterranean is the position of Malta. Nothing from the Platonic tradition
connects the islands to Atlantis, but the central Mediterranean too has been suggested as a location of
the sunken island. [7] It is easier to associate Malta with the tradition of Diodorus than of Plato. The
Libyan Amazons originally came from an island too, identified as having a volcano. The only large
island in this area that is home to a volcano is Sicily. We may consider whether Malta and Sicily were
once linked, politically if not physically. It is also relevant that the temple-building period on Malta
(c3500-2500 BC) predates the establishment of Dynastic Egypt.
The zone of faulting takes a loop offshore north of Tunisia, passing through Sicily and around the
shores of the Adriatic Sea forming the Adria micro-plate. Although we find in Italy a zone of frequent
earthquakes and volcanism, these are not the ‘mega-quakes’ that occur along subduction faults.
Although locally destructive, they are not usually powerful enough to generate tsunamis or the
widespread destruction that was associated with, for example, the Lisbon or Cretan earthquakes. In
this region it is the volcanoes that present the true danger.
In a recent investigation of sea level changes around Malta by Furlani-et-al, the specialists conclude
that the island has been ‘stable’ since the Ice Age and follows the predicted eustatic sea-level curves.
They see no need to invoke local isostatic or tectonic movements that specialist researchers employ
to rescue divergence from the expected eustasy. [8] The study cites the sea level curve of Lambecket-al (2011) for the Mediterranean Sea; indeed they conclude that this region has been tectonically
stable for some 125,000 years! [9] However, when we find such reliance on sea-level modelling we
should be cautious, for this is adding a new wing to a castle already built on sand. No-one really
knows how big the Pleistocene ice-caps were; no-one knows for certain how much sea-ice melted, or
why the ice sheets melted; or why they formed in the first place. It’s all cumulative academic opinion
served-up as proven fact.
Nevertheless, the specialist view remains that the central Mediterranean has been stable throughout
the Holocene. No sunken Atlantis here and no source of mega-quakes either. However, geologists
thought the same about Cascadia – another supposedly stable subduction zone – until evidence of the
1700 tsunami was found along the Canadian coast. The central Mediterranean too, could be a
potential site of subduction mega-quakes – but the specialists offer no evidence that they occurred in
our timeframe.
The largest documented earthquake and tsunami in this region was the magnitude-7 quake at
Taormina, Sicily in 1908, identified as slip along a normal fault rather than subduction.
However, we must again note that despite its severe local effects, the Taormina quake did not result
in sinking or liquefaction on neighbouring islands, such as Malta and Gozo, nor on Sicily; a more
powerful event is needed to match the description given by Diodorus.
Greece and the Aegean Sea
According to Plato, it was during the era of Atlantis that the ground subsided away from around the
Acropolis, leaving the rocky outcrop that we know today. Archaeologists find little early archaeology
on that site, other than Neolithic pottery around the Klepsydra spring; but a few shards of pottery do
not a city make! Perhaps, one day, we may find the remains of an ancient city; and the soldiers, who
“sank into the earth” at the same time as Atlantis was swallowed by the sea. The Egyptian priest
states that Athens was founded before Saïs (an apocryphal thousand years earlier according to the
Timaeus). Plato’s description is informative here: Greece had not yet become “the bones of the
wasted body” as it is described in the Critias. We may ask if there is any archaeological or other
scientific evidence to confirm the date of this geological and climate transition.
Greece and the Aegean micro-plate are such a seismically active zone that no-one can doubt that
earthquakes and tsunamis have been a regular occurrence as far back as we wish to look. However,
to attach a date or magnitude to any specific quake is much more difficult; to link any one of them to
a legendary catastrophe is even more problematic. There are so many Greek legends about floods
that it would be fruitless to pursue them all here (see Gallanopoulos above). Plato’s own description
mentions three ancient floods that washed away the soil from around the Acropolis.
An interesting summary-analysis of the Acropolis mound is given by geologist Callan Bentley. He
remarks that: “The hill used to be larger, but is being nibbled away over time from the sides. It’s an erosional
remnant of a much larger thrust sheet”, but precise dating of these collapses is something that we must
await.
Plato’s narratives do offer us other clues. The most useful dating indicator is his description of the
former temperate climate of Greece. Plato describes: “the happy temperament of the seasons” [Jowett
translation]. Again, in Critias we find: “the soil benefited from an annual rainfall which did not run to waste
off the bare earth as it does today” [Desmond Lee translation]. This description corresponds best with
what we know of the mid-Holocene climate of Europe, which climatologists coincidentally term the
Atlantic pollen zone. This name has nothing to do with Plato, but is due to its oceanic characteristics of
warm summers and cool winters, without extremes of temperature. For Europe, the transition to the
more extreme Sub-Boreal period is placed loosely around 3000 BC. We may note again the
synchronism with the emergence of the Nile delta and the establishment of Neit’s temple at Saïs,
concurrent with the First Dynasty of Egypt.
Pollen evidence reveals the initial stages of agriculture on the northern Thessaly plain from the early
Neolithic, extending eventually to the entire plain. [10] A further dating indicator is that we also know
there were people disturbing the natural flora. Plato describes hill-tops covered with trees that were
cut down in ancient times to roof buildings that were still standing in his own day. In cores takes from
the former Lake Viviis in eastern Thessaly the history of the vegetational sequences has been
determined. The specialists detect the earliest signs of Neolithic agriculture, which decreased during
the early Bronze Age and recovered from the Late Bronze Age onwards. Another recent thesis
suggests a similar sequence on the Peloponnese, signifying a wet-dry transition between 5300 BP and
4700 BP [11] Together with the changes in pollen signature, this climate transition confirms the late
fourth millennium BC as the era that best fits Plato’s description.
We may find numerous indicators worldwide of climate and sea-level change converging around this
date. The mid-Holocene corresponds to the period when the Sahara region turned from a grassy
savannah to desert conditions. Although some investigators try hard to turn this wet-to-dry transition
into a gradual process determined by the Earth’s orbit (‘orbital forcing’) others are clear that the
transition was more rapid.
The onset of desert conditions in the Sahara has been determined by cores from the sea-bed off
Mauretania. [12] Here it may be shown that the annual deposition of wind-blown desert sand was
interrupted between the close of the Ice Age and the mid-Holocene. This is termed the African
Humid Period, when the Sahara region was vegetated and could to sustain large lakes. The study finds
that marine sediments lack the temporal resolution to precisely date the onset of desert conditions to
within a century; they pin it down to four centuries around 5490±190 BP. One may note (as with
many such studies) that the co-authors only dare speak in terms of gradual causes; concluding that it
occurred when summer insolation crossed a threshold of 4.2% greater than present, thus reducing
the effect of the African monsoons.
We may note from the account of the Libyan Amazons’ conquests as given by Diodorus that he tells
of their defeated enemies taking refuge in a forested region. This offers a clue that we are looking at
events from before the dry desert climate set-in and before the displaced Libyan tribes sought refuge
in the Nile valley and delta. This would be contemporary with the temples of Malta and the civilisation
of the megalith builders along the Atlantic coast. We may have a glimpse here of predynastic Egypt
and its Libyan neighbours. This era, we are told, was contemporary with the Atlantian cities in North
Africa.
We should perhaps also note the negative dating indicator regarding Thera-Akrotiri. Plato does not
mention a volcano. Although the Thera eruption was one of the largest of historical times and despite
the tsunami that it triggered, no firm evidence can be cited here that it caused major earthquakes or
subsidence on mainland Greece. Even if such were to be found, the pollen evidence noted above
suggests that the modern agricultural conditions on the peninsula were already in place long before
this Bronze Age eruption.
Conclusions
When we follow strictly the text of Timaeus and Critias and look to cross-disciplinary evidence then the
conventional rationalization fails us; it only works if you deem the story to be Plato’s own fiction.
Scholars of Greek and archaeologists who argue in favour of Thera/Akrotiri have to selectively ignore
the absence of climate changes on the Greek mainland at the same era, as well as turning a blind-eye
to the synchronism with the foundation of Neit’s temple. Both of these indicators suggest a date
much earlier: in the mid-Holocene: the Atlantic – Sub-Boreal transition, the mid-Neolithic, or
whichever label you prefer to assign it.
The Thera-Santorini-Akrotiri solution for Atlantis that is used as a safe non-controversial explanation
simply does not fit the internal evidence of the narratives and comes no closer than some of the ideas
promoted by popular enthusiasts; its only saving grace are the academic credentials of those who
adhere to it, who might claim to be somehow more qualified or knowledgeable than the rest of us.
Not only does the Thera explanation ignore the indicators of date but neither does it fit the
geographical description. A city may indeed have been destroyed at Akrotiri, or on Crete, but where
is the huge island-continent described by Plato; where is the vast rectangular plain and the canals; and
how does it tally with a location beyond the Pillars of Heracles?
It must also be noted that the strongest documented modern quakes, such as the 1755 Lisbon event,
did not trigger mega-quakes along neighbouring faults, or sea-level changes within the wider
Mediterranean. Still less can they explain how an earthquake or volcanic event could trigger a
permanent climate transition in North Africa and Europe. The inference must be that whatever
happened around the mid-Holocene was an exceptional event of a much greater scale than a
magnitude-9 earthquake. Remember, it is the ancient source itself that links the Atlantis story with a
catastrophe from the heavens – it is not some speculative creation of modern authors.
This author’s recommendation therefore stands. Whenever you find a conflict between the opinion of
a modern expert and that given in an ancient text then you should always prefer the source closest to
the events. Trust in your most ancient historical source: Plato – or should that be: Sonchis of Saïs?
Notes:
1) The long reigns of the Egyptian gods are found along with the chronicle of Manetho that forms the basis of
modern Egyptian chronology; and which gives a total for reigns of gods, demigods, and spirits of the dead
covering 24,925 years prior to the dynasties of kings. It is likely that the priests of Saïs followed a similar
sacred chronology and therefore included part of this within the Atlantis date.
2) Diodorus Siculus, Library of History, Book III. 52-55. Diodorus is careful not to confuse the Libyan Amazons
with the Amazons of Asia Minor who flourished later, a generation before the Trojan War. Be careful! For, we
don’t know with certainty the era of the Trojan War either. It is another instance of cumulative academic
opinion that has morphed into fact.
3) Diodorus Siculus, Library of History, Book IV. 18. 1-7. Diodorus tries to align the Greek and Egyptian
legends about Heracles and his pillars but creates only more confusion for us. He says that there was both an
earlier and a later Heracles, whose achievements have become amalgamated over time. Diodorus says (in
Book III. 7.55) that Heracles entirely destroyed the Libyan Amazons on his way west to the straits to set-up his
pillars; and further relates that Heracles in doing so built out into the sea to narrow the straits.

Catastrophes: from Atlantis to the Aegean
Paul Dunbavin (2019)
Summary:
This discussion compares the popular-academic rationalisation of Plato’s Atlantis as a fictional
memory of the Thera-Santorini eruption with the alternative based on a stricter adherence to the
internal evidence of the narratives. It also posits that the ultimate source is Libyan-Egyptian rather
than Greek and that any solution must also comply with the additional semi-historical information
supplied by Diodorus Siculus in his Histories. This is taken together with an analysis of the known
geological and climate events of prehistory as compared to those suggested in the narratives.
The Athens Acropolis and Mount Lycabettus were occupied at least 6,000 years ago during the Greek Neolithic. Picture

Modern commentators who discuss Plato’s Atlantis and its demise will typically fall into two camps.
The first would be the scholars of Greek literature and others that follow their lead, who prefer to
retain the story within the realm of Greek mythology; they would treat it as Plato’s literary fiction
based solely upon his own philosophy and knowledge of the ancient world. Typically such
commentators rationalise Atlantis as a hazy memory of ancient Crete or of the Thera (Santorini)
eruption and tsunami that destroyed the city of Akrotiri on that island. However, this supposition
ignores many internal statements of the narratives and neglects the additional details about Atlantians
given by Diodorus Siculus. The hypothesis has become a regular feature in various much-repeated
television series linking Atlantis and ancient Cretan civilization.
The second group of commentators are the diverse popular enthusiasts, who would seek to locate
the lost city in a variety of places, from the Caribbean to the poles, selecting only those elements
from Plato that they need and discarding the rest. Many of these also neglect Diodorus Siculus.
There is a reasonable third approach: which is to consider Plato’s account for the most-part truthful
and to analyse Atlantis and its catastrophe as a degraded history of ancient events; preserved in Egypt,
and brought back to Greece by the sage Solon in the sixth century BC just as Plato says. Any
proposed solution must therefore respect all the details of the ancient story that we have inherited
from Solon’s Egyptian source: Sonchis of Saïs. It is then possible to compare the legend with Egyptian
rather than Greek tradition; and with the wider tradition of North Africa as I did in Towers of Atlantis
and earlier books. This would transfer tenure of the story away from Greek scholarship to the
Egyptologists – but these specialist-archaeologists don’t want it! They would shy away from being
tainted by speculation about Atlantis.
Those who regard Atlantis as Plato’s fiction seldom look beyond the Thera eruption of c.1625. For
this to work they have to discard the fabulously long chronology supposedly given to Solon by the
Egyptian priest; indeed his estimate of 9,000 years before his own time merely reinforces their
scepticism as there is scant evidence of settlements in Greece from such an early date. Plato’s
timescale therefore has to be reduced by a factor of ten to make it credible. Another argument
employed is that Plato’s references to bronze would mean that Atlantis could not be older than the
Bronze Age. However, as I argued in Towers of Atlantis the date of the Bronze Age itself is constantly
being pushed further back in time by archaeological discoveries and is now set as early as 3200 BC for
the Aegean. Those who wish to pursue the historiography may like to read the classic paper of 1960
by A.G. Gallanopoulos, which discussed the original excavations of Professor Marinatos, along with a
survey of ancient Greek tsunami references that retain their relevance.
The true dating indicators within Plato’s narratives are the statements that Atlantis and its
catastrophe fell before the establishment of the Temple of Neit and its institutions at Saïs in the
Egyptian Delta. In Timaeus the priest puts the foundation of Saïs at 8,000 years before his own time
and that of Athens 1,000 years earlier; in Critias he says that 9,000 years had elapsed. This association
would place the events right at the foundation of Dynastic Egypt, around 3100 BC or during the
earlier predynastic era – and therefore at least 1500 years earlier than the Thera eruption. Those
unfamiliar with the Egyptian goddess Neit may like to read these links:
Neit was a war goddess of probable Libyan origins equivalent to Greek Athene. The religion of Neit
was at its strongest during the First Dynasty after the unification of Upper and Lower Egypt.
Egyptologists find the mastaba tombs of the First Dynasty kings – and also their queens who bore
titles derived from the goddess Neit. It follows logically that if the Temple of Neit was established in
the delta as long ago as the First Dynasty then we cannot set the era of Atlantis, or the catastrophe that
destroyed it, any later than this date. The long-chronology, stated by Sonchis to Solon to derive from
“sacred records”, can then be seen as entirely consistent with the long-reigns of gods and demi-gods
whom the Egyptians believed had ruled the Nile valley prior to the dynasties of mortal kings. [see
Note 1] It is therefore relevant to seek a geological catastrophe that could sink an island or a city
from a time before the establishment of the First Dynasty – the late fourth millennium BC.
A tectonic puzzle! The Mediterranean Sea is a seismically complex region with numerous fault lines, some of which are
ancient and inactive. Shown here, for simplicity, are just the principal active subduction faults or crumple zones together
with the normal faults where sideslip may occur. It is possible that a mega-quake in one region such as the Atlantic could
trigger other events further east along this line of activity.
Another internal detail is that the submergence of the city and its island corresponded with great
earthquakes in Greece that destroyed ancient Athens and its armies – who had just fought-off an
attack by Atlantians from the west. We may ask: what links Greece and the Atlantic Ocean? The
obvious connection is the geological fault that runs from the Azores in mid-Atlantic through the Strait
of Gibraltar, onward to Malta and Sicily in the central Mediterranean and then to the Aegean Sea. The
geologists tell us that this is where the African continental plate is being subducted beneath the vast
Eurasian plate; and the Aegean micro-plate is all that remains of the ancient Tethys Ocean that
separated them. Subduction zones and their volcanoes are the most unstable regions on the planet;
where earthquakes tend to be at their greatest magnitude, but occur only after deceptively long
intervals of apparent stability.
Before we examine the geology, we should also review the parallel chronicle offered by Diodorus
Siculus, who also tells us about Atlantians (a slightly different spelling but clearly related) and who
possessed great cities. He goes-on to describe a matriarchal race called the Amazons, who similarly
worshipped the goddess Neit-Athene; they conquered an Atlantian city named Cernê situated
somewhere along the Libyan (North African) coast. The city of the Libyan Amazons was called
Cherronesus (‘peninsula’) and it lay in the marsh Tritonis; generally identified with low-lying Chotts of
Tunisia, but no-one really knows where it was. At some later time this city too was submerged in a
time of great earthquakes:
“…the marsh Tritonis disappeared from sight in the course of an earthquake, when those parts of it which lay
towards the ocean were torn asunder”. [Note 2]
It is then logical to ask whether this remembers the same geological event that is recalled in the
Atlantis legend. Plato, in Timaeus also says: “later… [there came] earthquakes and floods of extraordinary
violence”. If we treat Atlantis as an Egyptian rather than a Greek history then we have here two
independent accounts, both ultimately of north-African derivation, that recall: Atlantians, the goddess
Neit-Athene, a catastrophic submergence and a great earthquake. Too many coincidences here to just
ignore!
It is sometimes forgotten that we have very few ways of dating ancient earthquakes and volcanic
eruptions unless there is a historical report. For example archaeologists still argue about the true date
of the Thera eruption – some want to place it around 1500 BC; others following carbon-14 and treering dating prefer 1600-1645 BC. For ancient earthquakes we can say even less; even if there is some
artefact to be carbon-dated, the magnitude of an ancient quake can be only subjective specialist
opinion. Some idea of the difficulties can be gained from the significant earthquakes database, [1]
To attempt a dating of the earthquakes recalled by Diodorus is therefore problematic; the specialists
will only trust a firm historical report, whereas the historical investigator wants the geologist to
suggest a date. From the wording we can see that the ancient earthquake was no minor episode;
Diodorus recalls that low-lying regions towards the Ocean were “torn asunder”. This sounds very
much like a mega-quake (magnitude 8.5 or greater) of the kind expected along a subduction zone,
resembling those experienced more recently in Alaska and Chile. Diodorus Siculus or his lost source
could not have known that two thousand years later geologists would discover that the Algerian coast
was a mountain-building subduction zone, in order to invent a ‘mythical’ ancient catastrophe in just
the right location. This kind of coincidence is what I have elsewhere termed a ‘mythological fossil’: an
element within a myth that can be extracted and independently tested by science. Somewhere along
the Mediterranean coast between Tunisia and Morocco there may be two lost cities waiting to be
discovered, but precisely where cannot be discerned from the vague geography of Diodorus! It should
be noted that neither of these lost cities would be Atlantis – that was somewhere else.
To commence at the western-end of the line of faults, in the Atlantic Ocean, we find the islands of the
Azores; for so long naively claimed as the peaks of the sunken continent. We can now see these midocean islands as a volcanic product of the transform fault that links the mid-Atlantic ridge of sea floor
spreading to the subduction zone of Iberia-Africa. The nature of the fault therefore changes around
the region of the Gorringe Ridge to the west of Cape St Vincent, where we find flat-topped
seamounts that were formerly volcanic islands. Reliable evidence, of precisely when they were above
the sea is still unavailable. Where oceanic plates of equal density collide they tend to push-up volcanic
island chains and one day the ridge will become a new peninsula of Iberia.
North Africa
East of the Gorringe Bank the fault splits, with one active branch running north-east across the Sierra
Nevada of southern Spain while the other continues through Morocco. Here we may hope to find
more evidence of ancient earthquakes. Perhaps the various ancient legends surrounding the Pillars of
Heracles do remember a series of real quakes that altered the coastline. The true active fault zone
continues along the North African coast: through Morocco-Algeria-Tunisia. The largest documented
earthquake here was that at magnitude-7, which occurred on 10 October 1980. [2] This is far from
the worst to be expected of a subduction zone and those recorded further east in Tunisia tend to be
of lesser magnitude. [3]
A catalogue of early historical earthquakes in Algeria lists one that occurred in Setif in 419 AD,
magnitude unknown, but severe enough to be recorded. [4] Early historical quakes are recorded in
Tunisia around 412 AD. A specialist dare not, of course, cite the legendary account of Diodorus
Siculus or his lost source Dionysius as ‘evidence’. Presumably Dionysius was citing historical sources
in the Great Library of Alexandria. For comparison, Old Alexandria itself was lost to the sea following
the earthquake and tsunami of 365 AD (estimated magnitude 8.5 off Crete). An account of this
tsunami and its effects are given by the Roman historian Ammianus Marcellinus:
The same tsunami may have been responsible for the inundation of Roman Neapolis in Tunisia. It is
therefore not unreasonable to hold that even older settlements have been lost to ancient quakes
further west along the coast of Africa.
Iberia
The Gorringe Ridge is believed to be the epicentre of the great Lisbon earthquake of 1755 that
destroyed the colonial economy of Portugal, if not quite the city itself. Recent estimates rate the
magnitude as no more than 8.5 – not quite the maximum 9.0 associated with a true subduction zone.
An excellent account of the Lisbon earthquake, leading to numerous references, is given at the
Volcano Café website.
Plato quite clearly locates his lost island and its city in the Atlantic Ocean beyond the Strait of
Gibraltar, but we shall not pursue that thread here. The evidence of Diodorus, from a completely
independent source, would mitigate any suggestion that it was Plato alone who gave the Atlantic
Ocean and its inhabitants a fictional name. Why has conventional scholarship neglected this
corroborating evidence from Diodorus? Perhaps because he offers us mythology derived from
unfashionable African sources, which attempts to rationalise the ‘pure’ Classical myths taught in
schools and universities.
Elsewhere in his histories, Diodorus offers a rationalised summary of the legend of Heracles and his
voyage to the west. This is Heracles the man, not yet the god! The hero’s legendary voyage and
labours were a later event than the war between the Atlantians and the Libyan Amazons. [Note 3] It is
apparent from this narrative that Heracles set up his legendary pillars at what we now know as the
Gibraltar Strait; and his voyages continued further west into the Atlantic, to Gades (modern Cadiz in
Andalucía) and north into Gaul. This independent source contradicts any suggestion that Plato or
Solon did not know where the legendary pillars were situated.
Plato and his source are consistent that the lost city was situated outside the straits and this has led
some commentators to link it with another legendary Bronze Age lost city named Tartessos; believed
to lie beneath the low-lying marshland between Cadiz and Seville, where silver has been mined since
ancient times. A lost city here there may have been, but similar arguments may be advanced against
this identification as apply for Thera and Akrotiri; It fails to meet the Atlantis description both in date
and geography. The Andalusian coast is subject to the same geological influences as were discussed
for the Lisbon earthquake.
The onshore record suggests a major tsunami in the Gulf of Cadiz around 4,000 years ago, with
perhaps as many as eight over the last 7,000 years. [5] We should also consider the effect of tsunamis
created by underwater landslides. These may be triggered at any time by forces not necessarily
associated with major earthquakes. In addition to the 1755 tsunami earlier underwater mud-flows
(turbidites) are dated to 218 BC, 3010–3960 BC and 7765–8065 BC. [6]
It is conceivable that the legendary report of Diodorus recalls an underwater landslide event of the
fourth millennium BC – but to accept an earthquake/tsunami solution here for the Atlantis ‘quake’
would require a mechanism to transmit its effects within the Mediterranean as far as Tunisia and
Greece.
Malta and Sicily
Pivotal within the central Mediterranean is the position of Malta. Nothing from the Platonic tradition
connects the islands to Atlantis, but the central Mediterranean too has been suggested as a location of
the sunken island. [7] It is easier to associate Malta with the tradition of Diodorus than of Plato. The
Libyan Amazons originally came from an island too, identified as having a volcano. The only large
island in this area that is home to a volcano is Sicily. We may consider whether Malta and Sicily were
once linked, politically if not physically. It is also relevant that the temple-building period on Malta
(c3500-2500 BC) predates the establishment of Dynastic Egypt.
The zone of faulting takes a loop offshore north of Tunisia, passing through Sicily and around the
shores of the Adriatic Sea forming the Adria micro-plate. Although we find in Italy a zone of frequent
earthquakes and volcanism, these are not the ‘mega-quakes’ that occur along subduction faults.
Although locally destructive, they are not usually powerful enough to generate tsunamis or the
widespread destruction that was associated with, for example, the Lisbon or Cretan earthquakes. In
this region it is the volcanoes that present the true danger.
In a recent investigation of sea level changes around Malta by Furlani-et-al, the specialists conclude
that the island has been ‘stable’ since the Ice Age and follows the predicted eustatic sea-level curves.
They see no need to invoke local isostatic or tectonic movements that specialist researchers employ
to rescue divergence from the expected eustasy. [8] The study cites the sea level curve of Lambecket-al (2011) for the Mediterranean Sea; indeed they conclude that this region has been tectonically
stable for some 125,000 years! [9] However, when we find such reliance on sea-level modelling we
should be cautious, for this is adding a new wing to a castle already built on sand. No-one really
knows how big the Pleistocene ice-caps were; no-one knows for certain how much sea-ice melted, or
why the ice sheets melted; or why they formed in the first place. It’s all cumulative academic opinion
served-up as proven fact.
Nevertheless, the specialist view remains that the central Mediterranean has been stable throughout
the Holocene. No sunken Atlantis here and no source of mega-quakes either. However, geologists
thought the same about Cascadia – another supposedly stable subduction zone – until evidence of the
1700 tsunami was found along the Canadian coast. The central Mediterranean too, could be a
potential site of subduction mega-quakes – but the specialists offer no evidence that they occurred in
our timeframe.
The largest documented earthquake and tsunami in this region was the magnitude-7 quake at
Taormina, Sicily in 1908, identified as slip along a normal fault rather than subduction.
However, we must again note that despite its severe local effects, the Taormina quake did not result
in sinking or liquefaction on neighbouring islands, such as Malta and Gozo, nor on Sicily; a more
powerful event is needed to match the description given by Diodorus.
Greece and the Aegean Sea
According to Plato, it was during the era of Atlantis that the ground subsided away from around the
Acropolis, leaving the rocky outcrop that we know today. Archaeologists find little early archaeology
on that site, other than Neolithic pottery around the Klepsydra spring; but a few shards of pottery do
not a city make! Perhaps, one day, we may find the remains of an ancient city; and the soldiers, who
“sank into the earth” at the same time as Atlantis was swallowed by the sea. The Egyptian priest
states that Athens was founded before Saïs (an apocryphal thousand years earlier according to the
Timaeus). Plato’s description is informative here: Greece had not yet become “the bones of the
wasted body” as it is described in the Critias. We may ask if there is any archaeological or other
scientific evidence to confirm the date of this geological and climate transition.
Greece and the Aegean micro-plate are such a seismically active zone that no-one can doubt that
earthquakes and tsunamis have been a regular occurrence as far back as we wish to look. However,
to attach a date or magnitude to any specific quake is much more difficult; to link any one of them to
a legendary catastrophe is even more problematic. There are so many Greek legends about floods
that it would be fruitless to pursue them all here (see Gallanopoulos above). Plato’s own description
mentions three ancient floods that washed away the soil from around the Acropolis.
An interesting summary-analysis of the Acropolis mound is given by geologist Callan Bentley. He
remarks that: “The hill used to be larger, but is being nibbled away over time from the sides. It’s an erosional
remnant of a much larger thrust sheet”, but precise dating of these collapses is something that we must
await.
Plato’s narratives do offer us other clues. The most useful dating indicator is his description of the
former temperate climate of Greece. Plato describes: “the happy temperament of the seasons” [Jowett
translation]. Again, in Critias we find: “the soil benefited from an annual rainfall which did not run to waste
off the bare earth as it does today” [Desmond Lee translation]. This description corresponds best with
what we know of the mid-Holocene climate of Europe, which climatologists coincidentally term the
Atlantic pollen zone. This name has nothing to do with Plato, but is due to its oceanic characteristics of
warm summers and cool winters, without extremes of temperature. For Europe, the transition to the
more extreme Sub-Boreal period is placed loosely around 3000 BC. We may note again the
synchronism with the emergence of the Nile delta and the establishment of Neit’s temple at Saïs,
concurrent with the First Dynasty of Egypt.
Pollen evidence reveals the initial stages of agriculture on the northern Thessaly plain from the early
Neolithic, extending eventually to the entire plain. [10] A further dating indicator is that we also know
there were people disturbing the natural flora. Plato describes hill-tops covered with trees that were
cut down in ancient times to roof buildings that were still standing in his own day. In cores takes from
the former Lake Viviis in eastern Thessaly the history of the vegetational sequences has been
determined. The specialists detect the earliest signs of Neolithic agriculture, which decreased during
the early Bronze Age and recovered from the Late Bronze Age onwards. Another recent thesis
suggests a similar sequence on the Peloponnese, signifying a wet-dry transition between 5300 BP and
4700 BP [11] Together with the changes in pollen signature, this climate transition confirms the late
fourth millennium BC as the era that best fits Plato’s description.
We may find numerous indicators worldwide of climate and sea-level change converging around this
date. The mid-Holocene corresponds to the period when the Sahara region turned from a grassy
savannah to desert conditions. Although some investigators try hard to turn this wet-to-dry transition
into a gradual process determined by the Earth’s orbit (‘orbital forcing’) others are clear that the
transition was more rapid.
The onset of desert conditions in the Sahara has been determined by cores from the sea-bed off
Mauretania. [12] Here it may be shown that the annual deposition of wind-blown desert sand was
interrupted between the close of the Ice Age and the mid-Holocene. This is termed the African
Humid Period, when the Sahara region was vegetated and could to sustain large lakes. The study finds
that marine sediments lack the temporal resolution to precisely date the onset of desert conditions to
within a century; they pin it down to four centuries around 5490±190 BP. One may note (as with
many such studies) that the co-authors only dare speak in terms of gradual causes; concluding that it
occurred when summer insolation crossed a threshold of 4.2% greater than present, thus reducing
the effect of the African monsoons.
We may note from the account of the Libyan Amazons’ conquests as given by Diodorus that he tells
of their defeated enemies taking refuge in a forested region. This offers a clue that we are looking at
events from before the dry desert climate set-in and before the displaced Libyan tribes sought refuge
in the Nile valley and delta. This would be contemporary with the temples of Malta and the civilisation
of the megalith builders along the Atlantic coast. We may have a glimpse here of predynastic Egypt
and its Libyan neighbours. This era, we are told, was contemporary with the Atlantian cities in North
Africa.
We should perhaps also note the negative dating indicator regarding Thera-Akrotiri. Plato does not
mention a volcano. Although the Thera eruption was one of the largest of historical times and despite
the tsunami that it triggered, no firm evidence can be cited here that it caused major earthquakes or
subsidence on mainland Greece. Even if such were to be found, the pollen evidence noted above
suggests that the modern agricultural conditions on the peninsula were already in place long before
this Bronze Age eruption.
Conclusions
When we follow strictly the text of Timaeus and Critias and look to cross-disciplinary evidence then the
conventional rationalization fails us; it only works if you deem the story to be Plato’s own fiction.
Scholars of Greek and archaeologists who argue in favour of Thera/Akrotiri have to selectively ignore
the absence of climate changes on the Greek mainland at the same era, as well as turning a blind-eye
to the synchronism with the foundation of Neit’s temple. Both of these indicators suggest a date
much earlier: in the mid-Holocene: the Atlantic – Sub-Boreal transition, the mid-Neolithic, or
whichever label you prefer to assign it.
The Thera-Santorini-Akrotiri solution for Atlantis that is used as a safe non-controversial explanation
simply does not fit the internal evidence of the narratives and comes no closer than some of the ideas
promoted by popular enthusiasts; its only saving grace are the academic credentials of those who
adhere to it, who might claim to be somehow more qualified or knowledgeable than the rest of us.
Not only does the Thera explanation ignore the indicators of date but neither does it fit the
geographical description. A city may indeed have been destroyed at Akrotiri, or on Crete, but where
is the huge island-continent described by Plato; where is the vast rectangular plain and the canals; and
how does it tally with a location beyond the Pillars of Heracles?
It must also be noted that the strongest documented modern quakes, such as the 1755 Lisbon event,
did not trigger mega-quakes along neighbouring faults, or sea-level changes within the wider
Mediterranean. Still less can they explain how an earthquake or volcanic event could trigger a
permanent climate transition in North Africa and Europe. The inference must be that whatever
happened around the mid-Holocene was an exceptional event of a much greater scale than a
magnitude-9 earthquake. Remember, it is the ancient source itself that links the Atlantis story with a
catastrophe from the heavens – it is not some speculative creation of modern authors.
This author’s recommendation therefore stands. Whenever you find a conflict between the opinion of
a modern expert and that given in an ancient text then you should always prefer the source closest to
the events. Trust in your most ancient historical source: Plato – or should that be: Sonchis of Saïs?
Notes:
1) The long reigns of the Egyptian gods are found along with the chronicle of Manetho that forms the basis of
modern Egyptian chronology; and which gives a total for reigns of gods, demigods, and spirits of the dead
covering 24,925 years prior to the dynasties of kings. It is likely that the priests of Saïs followed a similar
sacred chronology and therefore included part of this within the Atlantis date.
2) Diodorus Siculus, Library of History, Book III. 52-55. Diodorus is careful not to confuse the Libyan Amazons
with the Amazons of Asia Minor who flourished later, a generation before the Trojan War. Be careful! For, we
don’t know with certainty the era of the Trojan War either. It is another instance of cumulative academic
opinion that has morphed into fact.
3) Diodorus Siculus, Library of History, Book IV. 18. 1-7. Diodorus tries to align the Greek and Egyptian
legends about Heracles and his pillars but creates only more confusion for us. He says that there was both an
earlier and a later Heracles, whose achievements have become amalgamated over time. Diodorus says (in
Book III. 7.55) that Heracles entirely destroyed the Libyan Amazons on his way west to the straits to set-up his
pillars; and further relates that Heracles in doing so built out into the sea to narrow the straits.
