An A-Z Guide To The Search For Plato's Atlantis


Joining The Dots

Joining The Dots

I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato's own words, tempered with some critical thinking and a modicum of common sense.

Dendera Zodiac

The Dendera(h) Zodiac is a well-known bas-relief taken from the ceiling of the Hathor temple at Dendera in Egypt. The temple was constructed during the Graeco-Roman and removed by the French in 1821 and moved to Paris, where it can now be viewed in the Louvre.

Inevitably, there is controversy regarding the date that the zodiac was intended to represent. Not unexpectedly, the zodiac has also been drawn into the Atlantis debates with Albert Slosman claiming that zodiac indicates a date of July 27th 9792 for the destruction of Atlantis[0550]!  Slosman’s extreme ideas on the subject greatly influenced the thinking of others, including Patrick Geryl & Gino Ratinckx, Wolter Smit and Carlos Barcelo. Hossam Aboulfotouh has also offered an interpretation of the Dendera Zodiac(a) , with many more available on the internet.


Bourgon, Emilio

Emilio Bourgon is an Italian researcher, and a keen follower of the work of Albert Slosman. Bourgon agrees with BourgonSlosman that a terrible cataclysm 12,500 years ago resulted in the destruction of Atlantis recorded by Atlantis(a). Subsequently, survivors reached Morocco and eventually travelled to Egypt where they brought their civilisation and the memory of their origins.

Fernando Pó

Fernando Pó now called Bioko is an island in the Gulf of Guinea off the west coast of Africa. One site(a) has described Fernando Poo together with other islands (see São Tomé and Príncipe) in the Gulf of Guinea as the remnants of Atlantis. This idea was probably sparked by a myth on the African mainland which tells of the destruction of a large landmass in the Gulf and recorded by Albert Slosman, who spent some time in nearby Cameroon.



Aha-Men-Ptah has been claimed by some commentators, such as Albert Slosman, to have been the Egyptian name for Atlantis. This idea was adopted by Patrick Geryl. The term apparently originated in an Egyptian papyrus of the Middle Kingdom (2000-1750 BC). Joseph Munlo (1964- ), a science fiction writer, inspired by this has written a lengthy novel entitled Aha-Men-Ptah: The Empire of the Islands.

Smit, Wolter

Wolter Smit was born in Wanneperveen, Holland in 1945 and after a period of work in Switzerland, he now lives in France. He has worked as a freelance computer engineer, but currently concentrates on his research and writing.

Wolter_Smit_2He runs a website, in French and English(a) that investigates the Atlantis story, based on his book, Était – elle l’Atlantide? (Was this Atlantis?) [0716], in which he generally supports Otto Muck’s theory that an asteroid impact in the Atlantic led to the destruction of Atlantis.

In 2011 Smit published an English translation of his book[0887].

He develops the idea that this impact altered the earth’s axis and rate of rotation. Smit agrees with the date of 9792 BC for the destruction of Atlantis as proposed by Albert Slosman.

Smit has a valuable section, Population and Size, in which he calculates the size of the Atlantean army as 1,200,000.

Nevertheless, I feel that Smit undermines any claim to scientific objectivity by the introduction of the readings of Edgar Cayce into his dissertation. This is all the more inexplicable as Smit in his Foreword states that he does “not want to consider things about magic crystals” and then devotes so much of his book to the ramblings of Cayce who attributed a crystal power source to the Atlanteans.

Although there are a number of inaccuracies in Smit’s book, there are also some interesting sections that should be studied.


Slosman, Albert

Albert Slosman (1925-1981), was a French professor of mathematics and an expert in computer science, having helped NASA with some of their programs. As a member of the French Resistance, he was captured and tortured by the Gestapo. Ironically, after the Liberation of France, he was unjustly accused of desertion and deported to Cameroon. While there, he heard of a local myth that told of a great cataclysm with which God had punished the wickedness of man and almost completely inundated a large continent in the Atlantic, where we now have Fernando Poo (Macias Nguema Biyogo). Afterwards Slosman travelled to Egypt and while there began to study hieroglyphics and also engaged in a serious investigation of the Denderah Zodiac.

While travelling in the Moroccan Middle Atlas Mountains, near Midelt, he was interested in the metals found there thinking that there was a connection between Moroccan oricalcita, a copper derivative, and Plato’s orichalcum!

His Egyptian studies led him to conclude that (i) Atlantis existed in the Atlantic and that after its submergence survivors migrated across North Africa and eventually became settled in Egypt and that (ii) the Denderah Zodiac indicated a July 27th 9792 BC date for this destruction of Atlantis[0550]! He managed to publish ten books, two of which related to Atlantis, before his tragic death following a fall in 1981. Unfortunately, many more publications were still at various stages of development.

Wolter Smit, on his website, appears to accept Slosman’s interpretation of the Denderah Zodiac regarding the destruction of Atlantis. Likewise, Patrick Geryl and Gino Ratinckx were so impressed by Slosman’s interpretation that they incorporated parts of it into their book[066] on an impending catastrophe in 2012. Carlos Barceló is also a fan of Slosman’s interpretation.

More about Slosman can be found at the following Spanish language website(a).


NOTE: Juan Garcia Atienza also wrote a book entitled Los Supervivientes de la Atlantida.

Pagé, Jean-Louis (L)

Jean-Louis Pagé (1949- ) is the Canadian author of a 2001 bilingual, French/English; book, Atlantis Messages[501] that maintains that artefacts such as the Phaistos disk as well as Mayan and Aztec disks together with Egyptian frescos contain messages from Atlantean ancestors! He locates Atlantis in the Arctic and attributes its destruction to a rapid pole shift in 9792 BC. Some of this book would appear to be strongly influenced by the work of Albert Slosman.



Egypt was viewed by the Greeks of Plato’s time as guardians of ancient history and wisdom and consequently was a place of pilgrimage for many of its greatest philosophers, who travelled there to be initiated into the cults of Isis and Osiris. Gustav Parthey (1798-1872), the German antiquarian, researched the education of 40 leading philosophers, writers and politicians of ancient Greece and found that all had studied under Egyptian priests. In spite of this the Greeks arrogantly referred to all non-Greeks, including the Atlanteans (Crit. 113a) as ‘barbarians’.It is of interest that Athene after whom the Greek capital is named, originated in Egypt where she was worshipped as Neith.

The late Philip Coppens went as far as to suggest(a) that Greece was in fact an Egyptian colony!

Plato’s text seems to infer that the destruction of Atlantis in 9600 BC was contemporary with Egyptian civilisation, raising archaeological questions regarding the earliest date for the establishment of an organised society in Egypt. Unfortunately, there is not a lot to support this contention. The oldest known art in Egypt was discovered in 2007 when petroglyphs estimated to be 15,000 years old. The earliest culture along the Nile, identified by archaeologists is that of what is known as the Badarian dated to around 4500 BC. They produced basic pottery, jewellery and used stone tools although they had some knowledge of metals. The Badarians were followed by the Naqada who led on to what we identify as the spectacular ancient Egyptian civilisation. However, in 2007, rock carvings, similar in style to the Lascaux paintings were discovered near the village of Qurta, 650km south of Cairo. The 160 carvings, spread over 1.5km of rock face, discovered so far, mainly depict wild bulls and have been dated *to 13000 BC(h).*

September 2013 saw the publication(c)(d) of a more definitive date for the start of the state of Egypt, beginning with the reign of king Aha circa 3100 BC. The evidence indicated that the process of moving from the pre-Dynastic groupings to a form of statehood was more rapid than previous thought. This undermines even more firmly the claims of the Egyptians that their country was founded around 8,600 BC as reported by Plato.

It is not surprising that ancient Egypt has presented us with very many unanswered questions, some of which have been compiled, posted on Wikipedia but subsequently removed(g).

Many writers have remarked how all aspects of ancient Egyptian culture seem to have arrived fully developed, in fact later dynasties did not surpass some of the achievements of the earlier ones. The conclusion of some is that the fully matured civilisation of the early Egyptians was in fact a legacy from elsewhere.

Sanchuniathon refers to the original kings of Egypt calling them ‘Aleteans’. Albert Slosman claims[551] that survivors from Atlantis had migrated to Egypt. The archaeologist, Marcelle Weissen-Szumianska, in a 1965 book, Origines Atlantiques des Anciens Egyptiens, maintained that the pre-pharonic Egyptians originated in Atlantis, which had been situated in Morocco! Others suggest that Egypt was an Atlantean colony. The idea was brought to a ridiculous level by Augustus Le Plongeon who claimed that Egypt was a Mayan colony!

Robert Schoch has controversially dated the construction of the Sphinx to between 7000-5000 BC, while the megalithic structures at Nabta Playa suggest a sophisticated culture in that area around 5000 BC. Even if both these early dates are correct they are still over four and a half millennia short of Plato’s date. These most likely explanation is that Plato’s number of 9,000 years before Solon is incorrect as 9000 is too neat and may have been an number used to express uncertainty or exaggeration just as we speak of having ‘a million and one things to do’.

In 1897, a Russian scientist, A.N. Karnozhitsky was probably the earliest commentator to propose a close link between Egypt and Atlantis, placing the Pillars of Heracles near Sais and located Atlantis itself not far from the western mouth of the Nile.

Some years ago, Egypt was again been proposed as the original Atlantis, in a still (Mar. 2017) unpublished book, The Joshua Crossing, by N. R. James. However, 2006 did see a paper presented by Professor Hossam Aboulfotouh of Minia University, Egypt, placed Atlantis in the Nile Delta. The following year R. McQuillen also offered an Egyptian location for Atlantis, placing it at Pharos near Alexandria.

A novel idea has been put forward by Mary Whispering Wind(b), who bravely offers the idea that the Atlantean province of Egypt was in fact, Colchis, situated on the east coast of the Black Sea! She bases her claim on an interpretation of Herodotus (Book II.104/5) who was commenting on circumcision being only practiced by Egyptians, Ethiopians and Colchians, in my mind, stretching what Herodotus said beyond the acceptable.

An even more radical suggestion was made by Reinoud M. de Jong in a 2009 paper(f) where he boldly claimed “that during the whole period of the (Michigan) copper trade, America was part of the Egyptian Empire” and during the Old Kingdom “this huge empire was known as Atlantis”!

One blogger, from California, has gone so far as to suggest that the ‘Egypt’ which Solon visited was on the shores of the Sea of Marmara!(e)

Orichalcum is one of the many mysteries in Plato’s Atlantis narrative. It is mentioned five times in the Critias [114e, 116c-d, 119c] as a metal extensively used in Atlantis. I am not aware of any reference to it anywhere else in his writings, a fact that can be advanced as evidence of the veracity of his Atlantis story. Plato took the time to explain to his audience why the kings of Atlantis have Hellenised names. However, he introduces Orichalcum into the story without explanation suggesting that the metal was something known to the listeners. It is therefore natural to expect that metals might play an important part in determining the credibility of any proposed Atlantis location.

*Bronze was an alloy of copper and tin, while brass was a mixture of copper and zinc, their similarity is such that museums today refer to artefacts made of either refer to them as copper alloys.*

According to James Bramwell[195.91]Albert Rivaud demonstrated that the term ‘orichalcum’ was known before Plato and not just invented by him. Similarly, Zhirov notes that both Homer and Hesiod refer to the metal[0458.46], , as does Ibycus, the 6th century BC poet, who compares its appearance to gold suggesting a brasslike alloy. Thomas Taylor (1825) noted that in a fragment from a lost book of Proclus, he seems to refer to orichalcum under the name of migma(c). Wikipedia also adds that Orichalcum is also mentioned in the Antiquities of the Jews – Book VIII, sect. 88 by Josephus, who stated that the vessels in the Temple of Solomon were made of orichalcum (or a bronze that was like gold in beauty). Pliny the Elder points out that the metal had lost currency due to the mines being exhausted. Pseudo-Aristotle in ‘De mirabilibus auscultationibus’ describes orichalcum as a shining metal obtained during the smelting of copper with the addition of ‘calmia’, a kind of earth formerly found on the shores of the Black Sea, which is attributed to be zinc oxide.”

Orichalcum, or its equivalent Latin Aurichalcum, is usually translated as ‘golden copper’ referring to either its colour or composition (80% copper and 20% zinc) or both. However, Webster’s Dictionary translates it as ‘mountain-copper’ from ‘oros’ meaning mountain and ‘chalchos’ meaning copper.

Sir Desmond Lee described the metal as ‘imaginary’ without explaining away the classical references or the fact that In numismatics, orichalcum is the name given to a brass-like alloy of copper and zinc used for the Roman sestertius and dupondius. Very similar in composition to modern brass, it had a golden-yellow color when freshly struck.  In coinage, orichalcum’s value was nearly double reddish copper or bronze.  Because production cost was similar to copper or bronze, orichalcum’s formulation and production were highly profitable government secrets.”(m)

Modern writers have offered a range of conflicting explanations for both the origin and nature of orichalcum. A sober overview of the subject is provided by the Coin and Bullion Pages website(d).

In 1926 Paul Borchardt recounted Berber traditions that recalled a lost City of Brass. Salah Salim Ali, the Iraqi scholar, points[0077] out that a number of medieval Arabic writers referred to an ancient ‘City of Brass’ echoing the Orichalcum covered walls of Plato’s Atlantis.

Ivan Tournier, a regular contributor to the French journal Atlantis proposed that orichalcum was composed of copper and beryllium. Tournier’s conclusion seems to have been influenced by the discovery in 1936 at Assuit in Egypt of a type of scalpel made from such an alloy(e).

An unusual suggestion was made by Michael Hübner who noted that “small pieces of a reddish lime plaster with an addition of mica were discovered close to a rampart” in his chosen Atlantis location of South Morocco. He links this with Plato’s orichalcum, but does so without any great enthusiasm.

Jim Allen, promoter of the Atlantis in Bolivia theory, claims that a natural alloy of gold and copper is unique to the Andes. Tumbaga is the name given by the Spaniards to a non-specific alloy of gold and copper found in South America. However, an alloy of the two that has 15-40% copper, melts at 200 Co degrees less than gold. Dr. Karen Olsen Bruhns, an archaeologist at San Francisco State University wrote in her book, Ancient South America[0497], “Copper and copper alloy objects were routinely gilded or silvered, the original colour apparently not being much valued. The gilded copper objects were often made of an alloy, which came to be very important in all of South and Central American metallurgy: tumbaga. This is a gold-copper alloy which is significantly harder than copper, but which retains its flexibility when hammered. It is thus ideally suited to the formation of elaborate objects made of hammered sheet metal. In addition, it casts well and melts at a lower temperature than copper, always a consideration when fuel sources for a draught were the wind and men’s lungs. The alloy could be made to look like pure gold by treatment of the finished face with an acid solution to dissolve the copper, and then by hammering or polishing to join the gold, giving a uniformly gold surface”.

Enrico Mattievich also believed that orichalcum had been mined in the Peruvian Andes(b).

Jürgen Spanuth tried to equate Orichalch with amber. Paul Dunbavin links Orichalcum with Wales. Robert Ishoy implies a connection between obsidian and Orichalcum, an idea also promoted by Christian & Siegfried Schoppe, while Felice Vinci equates it with platinum.

Albert Slosman thought that there was a connection between Moroccan oricalcita, a copper derivative, and Plato’s orichalcum. Peter Daughtrey has offered [893.82] a solution from a little further north in Portugal where the ancient Kunii people of the region used ori or oro as the word for gold and at that period used calcos for copper.

Thorwald C. Franke has suggested[750.174] that two sulphur compounds, realgar and orpiment whose fiery and sometimes translucent appearance might have been Plato’s orichalcum. His chosen location for Atlantis, Sicily, is a leading source of sulphur and some of its compounds. I doubt this explanation as realgar disintegrates with prolonged exposure to sunlight while it and orpiment, a toxin, could not be described as metals comparable with gold and silver as stated by Plato.

Frank Joseph translates orichalcum as ‘gleaming or superior copper’ rather than the more correct ‘mountain copper’ and then links Plato’s metal with the ancient copper mines of the Upper Great Lakes. Joseph follows Egerton Sykes in associating ‘findrine’, a metal referred to in old Irish epics, with orichalcum. However, findrine was usually described as white bronze unlike the reddish hue of orichalcum.

Ulf Erlingsson suggested [319.61] that orichalcum was ochre, which is normally yellow, but red when burnt. He seems to have based this on his translation of the text Critias116b. In fact the passage describes the citadel flashing in a fiery manner, but it does not specify a colour!

Other writers have suggested that orichalcum was bronze, an idea that conflicts with a 9600 BC date for the destruction of Atlantis since the archaeological evidence indicates the earliest use of bronze was around 6000 years later.

Thérêse Ghembaza has kindly drawn my attention to two quotations from Pliny the Elder and Ovid  that offer possible explanations for Plato’s orichalcum (see Document 091011). The former refers to a Cypriot copper mixed with gold which gave a fiery colour and called pyropus, while Ovid also refers to a cladding of pyropus. She also mentions auricupride(Cu3Au), an alloy that may be connected with orichalcum.

Zatoz Nondik, a German researcher, has written a book about Plato’s ‘orichalcum’, From 2012 to Oreichalkos[0841], in which he describes, in detail, how the orichalcum may be related to Japanese lacquer and suitable for coating walls as described in the Atlantis(b) narrative!

The fact is that copper and gold mixtures, both natural and manmade, have been found in various parts of the world and have been eagerly seized upon as support for different Atlantis location theories. A third of all gold is produced as a by-product of copper, lead, and zinc production.

It is also recorded that on ancient Crete, in the Aegean, two types of gold were found, one of which was a deep red developed by the addition of copper. Don Ingram suggests that the reddish gold produced in ancient Ireland is what Plato was referring to.

Irrespective of what orichalcum actually was, I think it is obvious that it was more  appropriate to the Bronze Age than 9,600 BC. Furthermore, it occurs to me that Plato, who was so careful to explain or Hellenise foreign words so as not to confuse his Athenian audience, appears to assume that orichalcum is not an alien term to his audience.

The result of all of this is that Orichalcum has been advanced to support the location of Atlantis in North and South America, Sundaland, Ireland, Britain and the Aegean. Once again an unintentional lack of clarity in Plato’s text hampers a clear-cut identification of the location of Atlantis.

A fascinating anecdote relating the use of a term similar to ‘orichalcum’ to describe a mixture of copper and gold was used by a metalsmith in Dubai as recently as 2007 and is recounted on the Internet(a) .

The Wikipedia entry(f) for ‘orichalcum’ adds further classical references to this mysterious metal.

orichalcum32015 began with a report that 47 ingots of ‘orichalcum’ had been found in a shipwreck off the coast of Sicily and dated to around 600 BC(g). What I cannot understand is that since we never knew the exact composition of Plato’s alloy, how can anyone today determine that these recovered ingots are the same metal. Thorwald C. Franke has more scholarly comments on offer(h).  Jason Colavito has also applied his debunking talents to the subject(i). In June of the same year, orichalcum2Christos Djonis, in an article(j) on the Ancient Origins website, wrote a sober review of the media coverage of the shipwreck. He also added some interesting background history on the origin of the word ‘orichalcum’.

An analysis revealed(k) that those ingots were composed of 75-80% copper, 15-20% zinc, and traces of nickel, lead and iron, but no proof that this particular alloy was orichalcum. The recovery of a further 39 ingots from the wreck were reported in February 2017 and the excavation of the sunken ship continues.

The most recent explanation for the term comes from Dhani Irwanto who has proposed that orichalcum refers to a form zircon(l) that is plentiful on the Indonesian island of Kilimantan, where he has hypothesised that the Plain of Atlantis was located [1093.110].
