A Tsunami was probably first described in the 5th century BC by Thucydides when he wrote “in my opinion, the cause of the phenomenon was this: where the earthquake was most violent, the sea receded and was then pushed back with even greater violence, thus bringing about a flood. Such a thing would not have happened without an earthquake” (Peloponnesian War, Book III.89)(b). However, there are also conditions that can produce tsunamis inland, such as occurred around 500 AD inundating Geneva in the Alps(k)(m).
The word ‘tsunami’ first appeared in an English language publication in the September 1896 edition of National Geographic Magazine in which the devastation caused by an earthquake wave in Japan was graphically described.
Recent studies(g) indicate that a similar tsunami saved the Greek town of Nea Poteidaia from a Persian attack in 479 BC. Herodotus in reporting the event attributed the Persian defeat to divine intervention by Poseidon, god of the sea.
A similar event on an even greater scale has been one of the suggestions as the possible cause of the flooding of Atlantis. A 2002 paper(a), by Louisiana State University geologist, Gary Byerly and his team, identified an ancient asteroid impact that generated a tsunami that “swept around the earth several times, inundating everything except the mountains”. The study of ancient tsunamis is at a very early stage of development.
Ivan T. Sanderson in one of his books, Investigating the Unexplained , recounts an 1863 report of a 200-foot high tsunami which sped up the Ganges and Houghli Rivers in India killing tens of thousands of people without ‘snapping-off’ trees. He contrasts this with the tree stumps covering acres around East Creek, New Jersey that have all been broken off at the same height and where he suggested that only a tsunami could have caused such widespread and uniform destruction. In view of the fact that some of these cedar trees had six foot diameter trunks he speculates on the possible size of a tsunami that could bring about such extreme damage.
Perhaps even more relevant to the study of Atlantis is the evidence gathered by Jürgen Spanuth in his chapter on the ‘Natural Catastrophes of the 13th Century’ including an interesting section on tsunamis[015.167].
Marc-André Gutscher of the University of Western Brittany in Plouzané, France, has discovered evidence of ancient tsunami on Spartel Island, an Atlantis candidate, in the Gulf of Cadiz. Georgeos Diaz-Montexano has pointed out that Josephus, the 1st century Jewish historian, seems to describe the devastation caused by its assault on the Atlantic coast of Spain and Portugal at the time of the Lusitanians and Cantabrians in the 1st millennium BC.
Professor Stefano Tinti of Bologna University visited Sardinia and explained(r) “that until the 1980s no one was aware that tidal waves had occurred in the Mediterranean. But since 2004 scientists have identified 350 events of this type over a 2,500-year period,” and regarding the Sardinian tsunami “So what would have been required in our case?” he then asked. “We’re talking about a huge volume of water, some 500 metres high [the elevation up to which the nuraghi were affected]. Only a comet could do that, if the impact occurred very close to the coast and in a very specific direction,” he asserted. An event of this sort may have occurred near Cagliari, with the resulting wave devastating the plain of Campidano.”
Tinti has also noted(w) that generally speaking, the majority of tsunamis are generated by seismic rather than volcanic activity. Globally, volcanic tsunamis account for only 2% of the total, however, the profusion of volcanoes in Southern Italy has considerably increased this percentage. Furthermore, according to a recent article on the BBC website “The scale of the tsunami hazard from volcanoes that collapse into the sea has been underestimated.”(x)
More recently, Dhani Irwanto has written of the probable effect of tsunamis on his Indonesian Atlantis(y). Studies of the sedimentary record in a sea-cave in Sumatra have revealed the frequency and strength of tsunamis in the region over a five thousand year span from 5900 BC until 900 BC(u).
Tsunamis are also associated with destruction on Crete following the eruption of Thera in the 2ndmillennium BC. A TV documentary entitled Sinking Atlantis(i), provided graphic evidence of tsunami damage on Minoan Crete(h).
J.V.Luce cited[120.119] a number a local legends from around the Aegean that may have originated with the tsunami that followed the eruption on Thera.
However, the extent of this damage is strongly contested by W. Sheppard Baird(j) and he proposes instead that it was in fact more likely to have been a pyroclastic surge from the Theran eruption that caused most damage.
A recent report(d) concludes that a large tsunami generated by the volcanic activity of Mt. Etna around 6000 BC produced waves up to 43 feet high that struck the coasts of Greece and Libya. This event would have caused devastation on nearby Malta, where evidence of past tsunamis was published in the journal Zeitschrift für Geomorphologie. The research was carried out over three years by scientists from the University of Portsmouth, led by Dr Malcolm Bray with assistance from colleagues at the Department of Geography at the University of Malta(n). A 1693 earthquake generated the earliest recorded tsunami on Malta and as recent as 1908 Malta was hit by a tsunami that resulted from a catastrophic earthquake in the vicinity of the Strait of Messina(p).
On the Atlantic west coast of Ireland we have a 250 km2 locality, in County Clare, known as the Burren, which consists of limestone denuded of soil cover. Recently, strong evidence was discovered suggesting a 4000 BC tsunami in the region(o). For me the karst landscape of the Burren is reminiscent of areas of Malta.
Plato’s description does not support the idea of a tsunami as the primary cause of Atlantis’ inundation since tsunamis will eventually subside and return to the ocean, whereas Atlantis was still under water years after the event, causing a permanent navigation hazard. John Michael Greer makes a similar point [345.126] in relation to the megatsunami which struck Madagascar 2800 BC. Evidence of other ancient megatsunamis in Hawaii was presented to 2012 meeting of the American Geophysical Union(l). The power of megatsunamis is highlighted in an article the UK’s MailOnline website(t).
Recent excavations at Olympia on the Peloponnese peninsula, the location of the original Olympic Games, have pointed to the site having been repeatedly hit by devastating tsunamis during the past 7,000 years(c).
The Bunurong tribe in Australia have a ‘myth’ which explains the creation of Melbourne’s Port Philip Bay. A recent article(e) has linked this to a tsunami which resulted from the impact of Comet Manhuika south-west of New Zealand in the 15th century. A more cautious view of this event is expressed elsewhere(f).
The excellent livescience.com website has an interesting list of ten history-making tsunamis(q), while Wikipedia offers an extensive list of European tsunamis from prehistoric times until the present(s).
A 100-metre-high tsunami, caused by a landslide, one of the highest ever recorded was experienced in a remote area of Greenland in June 2017. Four lives were lost and eleven houses destroyed in the fishing village of Nuugaatsiaq, located on an island about 20 kilometres away(v).

Melqart was the son of El the supreme deity of the Phoenicians. He was the principal god of the city of Tyre and was sometimes known as Baal. As Tyre gained supremacy throughout the Phoenician world, Melqart also gained prominence. Melqart is the only Phoenician god mentioned in the Hebrew Bible. The Temple of Melqart in Tyre was similar to that built for Solomon in Jerusalem. This is understandable as craftsmen from Tyre built the temple in Jerusalem and there would have had a natural exchange of religious ideas, as they were neighbours. Herodotus describes the main entrance to the sanctuary as being flanked by two columns or pillars known as ‘betyls’, one made of gold and the other of ‘smaragdus’— often translated as ‘emerald.’
The cult of Melqart was brought to Carthage, the most successful Tyrian colony, and temples dedicated to Melqart are found in at least three sites in Spain; Gades (modern Cadiz), Ebusus, and Carthago Nova. Near to Gades, at the Strait of Gibraltar, the mountains on either side were first known as the Pillars of Melqart, and then later changed to the Pillars of Heracles. Across the Strait of Gibraltar, at the Atlantic coast of Morocco was the Phoenician colony of Lixus, where there was another temple of Melqart.
In classical literature, Melqart and Heracles have been referred to interchangeably, by many historians such as Josephus Flavius.
It is thought that the city of Cadiz was originally founded as Gadir (walled city) by the Phoenicians around 1100 BC, although hard evidence does not prove a date earlier than the 9th century BC. In his 2011 book, Ancient Phoenicia, Mark Woolmer has claimed [1053.46] that the archaeological evidence indicates a date around the middle of the 8th century BC.
It is regarded as the most ancient functioning city in Western Europe. Gadir had a temple that was dedicated to the Phoenician god Melqart. Some consider that the columns of this temple were the origin of the reference of the Columns of Heracles. Commentators on Plato’s Atlantis story have linked Cadiz (formerly Gades) with the second son of Poseidon, Gadirus.
The Hyksos is the name applied to two dynasties of foreign kings who ruled Egypt around 1650-1530 BC(a). Gerard Gertoux suggests three dynasties reigning from circa 1750- 1530!(l) They are generally accepted to have been a Semitic people, from an unknown land, who invaded Egypt around 1710 BC. They ruled for over a hundred years until defeated by the Egyptian Pharaoh Amasis I.
Their name was originally taken to mean ‘Shepherd Kings, but more recently, it is accepted that the Egyptian term ‘heqa-khase’ which means ‘rulers of foreign lands’ gives us a simple but credible title of ‘Foreign Kings’. It has been suggested by David J. Gibson (1904-1966) that the modern interpretation indicated that the Hyksos ruled a vast empire and has devoted a book to justifying this view(g).>This empire lay mainly to the the east of Egypt with the possible exception of Crete. Gibson identifies the Hyksos with the biblical Edomites!<
Walter Baucum summarises his view on the subject as follows, “The Early Hyksos Shepherd Rulers of Egypt were descendants of Shem and identical with Typhon and the Titans, the peoples of Set, and to some degree with the Hebrews. The early Hyksos were to a large degree Israelites but after they left, the Amalekites conquered Egypt and were also referred to as Hyksos”.
There have also been persistent suggestions that there were strong links between the Hyksos and Crete, as referred to above and below, but the exact nature of the links is unclear and may not be more than you get between nations trading over an extended period. The relevance of such links, if they were ever shown to be political rather than commercial, would take on new significance for supporters of the Minoan Hypothesis. Time will tell.
E. J. de Meester has suggested links between Crete and the Hyksos, an idea an included in an article by Philip Coppens(b). In a similar vein Diaz-Montexano claims that a study of the names of the Hyksos pharaohs suggests to him that they were proto-Greek or Mycenaeans.
An example of the diversity of opinions regards the origins of the Hyksos is a brief article written by Emilio Spedicato who identifies them with the Scythians. Gunnar Heinsohn (1943- ) is a German professor emeritus at the University of Bremen, who presented a paper entitled ‘Who were the Hyksos’ to the 6th International Congress of Egyptology in 1993, in which he concluded that they were to be identified with the Old-Akkadians(j).
Perhaps even more radical is the suggestion by Riaan Booysen that the Hyksos were the fleeing Israelites in the biblical Exodus story(c). In fact he claims that there were two ‘exoduses’ which coincided with two separate eruptions on Thera. This idea is not as new as it might seems as something similar was proposed by the 1st century AD Jewish historian Josephus(d).
Nick Austin also identifies the Hyksos as Jews [1661.184], but is more generous than Booysen claiming that there were four separate eruptions of Thera. Like many others he has also associated the biblical Exodus and the Plagues of Egypt with the Theran eruptions.
Ralph Ellis, among others, has endorsed(e)(f) the idea that the biblical Exodus and the historical Expulsion of the Hyksos describe the same event.
There are theories, many and varied, regarding the origins and post-Egyptian settlement of the Hyksos. Arguably, the most exotic was put forward by a Chinese geochemist, Sun Weidong, who proposed that Hyksos migrants were responsible for the founding of the Chinese civilisation!(h)(i)
In July 2020, it was reported that “new research led by Bournemouth University archaeologists supports the theory that the Hyksos, the rulers of the 15th Dynasty of ancient Egypt, were not from a unified place of origin, but Western Asiatics whose ancestors moved into Egypt during the Middle Kingdom, lived there for centuries, and then rose to rule the north of Egypt.”(k)
The full facts relating to the Hyksos’ rule are only slowly emerging(m) and I expect that it will be some years before a definitive history can be agreed.>Just over a year after I wrote this, In March 2021, Diego Ratti published Atletenu, in which he identified the Hyksos as Atlanteans, with their capital situated at Avaris in the eastern Nile Delta(n).<

Tarshish is a city referred to about a dozen times in the Bible and has been widely accepted as another version of Tartessos. Josephus, the Jewish historian who wrote during the 1st century AD, was confident that it referred to Tarsus in Cilicia, Turkey, the birthplace of St. Paul. The Septuagint Bible uses Karkendonos where it refers to Tarshish in Isaiah 23:1, which was the Greek form of the name for North African Carthage. This could imply that the founders of Carthage and Tarsus were the same. We know that Carthage was founded by Tyrians and we also know that Cilix, a Tyrian, gave his name to Cilicia when he settled it. Andis Kaulins has claimed that Carthage was possibly built on the remains of Tartessos (i)!
Utica was a Phoenician port city on the northern coast of what is now Tunisia. It no longer exists and its site is now some miles inland because of silting. It is also one of a number of suggested locations for Tarshish(f).
Tarshish/Tartessos is thought by many others to be alternative names for Atlantis. There is a consensus that it was a coastal city in Southern Spain, near modern Cadiz. Despite the efforts of many, its location is still unknown, which can probably be explained by the fact that the coastline has altered considerably over time. Adolf Schulten, who was convinced that Tartessos was Atlantis, spent many years searching, unsuccessfully, for Tarshish in Andalusia.
Other locations have been suggested, such as Tharros in Sardinia, Troy and even Malta where Tarxien may be considered an echo of Tarshish. Tharros, sometimes referred to as a ‘second Carthage’ had its port located as recently as 2008(d). The suggestion that Tharros was Tarshish was based on their similar sounding names and the reference to Tarshish in the Phoenician inscription on the ‘Nora Stone’ discovered at Nora on the south coast of Sardinia in 1773.
Quite a variety of locations have been offered as the site of Tarshish(f)(k).
>Aaron Arrowsmith (1750-1832), a British cartographer and geographer was of the view that “Tartessus was a territory established by adventurous traders who settled in the Iberian peninsula after moving from the ancient city of Tarsus in Asia Minor (modern Turkey).” <
It is accepted that biblical silver was sourced from ‘Tarshish’, initially assumed to be Tartessos in Spain. Recent studies employing lead isotope tests, when applied to Phoenician silver hoards(g) revealed that both Spain and Sardinia were possible sources. However, it might be argued that the Nora Stone may give Sardinia a somewhat stronger claim.
A more radical idea was put forward in 2012 by the Spanish researcher, José Angel Hernández, who proposed that the Tarshish of the Bible was to be found on the coastal region of the Indus Valley and that Tartessos was a colony of the Indus city of Lhotal and had been situated on both sides of the Strait of Gibraltar!(a)(b) This view is apparently supported by biblical references (1 Kings 9:26, 22:48; 2 Chr. 9:21) that note that the ‘ships of Tarshish’ sailed from Ezion-geber on the Red Sea’s Gulf of Aqaba!
However, if Tarshish was another name for Atlantis and according to the bible it existed at the time of Solomon, circa 1000 BC, we are confronted with a contradiction of Plato’s 9,000 years elapsing since the destruction of Atlantis and the visit of Solon to Sais. King Jehoshaphat reigned around 860 BC and planned to send a fleet to Tarshish, just 200 years before Solon, so the likelihood of Tarshish being Atlantis is a rather remote possibility.
A recent suggestion by a Dutch commentator, Leon Elshout, places the biblical Tarshish in Britain(h) and supported by a Christadelphian website(j).
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, which suggests that the metal was something well-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 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 English translation of Tournier’s paper was published in Atlantean Research (Vol 2. No.6, Feb/Mar.1950). In the same edition of A.R. Egerton Sykes adds a few comments of his own on the subject.<
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, “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 both it and orpiment, a toxin, could not be described as metals in any way 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(n) . 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, 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 to 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.
2015 began with a report that 47 ingots of ‘orichalcum’ had been found in a shipwreck off the coast of Sicily, near Gela, 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 salvaged 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, Christos 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.
>An extensive paper(o) on the Gela discovery reported “that Professor Sebastiano Tusa, an archaeologist at the office of the Superintendent of the Sea in Sicily, claimed the metal they had discovered in the remains of the ship was probably the mythical and highly prized red metal orichalcum.” However dissent was not long coming, as the paper also notes that “ Enrico Mattievich, a former physics professor at the Federal University of Rio de Janeiro, believes the metal has its origins in the Chavin civilisation that developed in the Peruvian Andes in around 1,200 BC. He claims the metal alloy is made from copper, gold and silver. He claims that the discovery off the coast of Gela is not true orichalcum.” I think that both are probably wrong as we do not know the exact chemical composition of Plato’s orichalcum and both are just engaging in speculation.<
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].
