Michigan entered the Atlantis gazetteer when Frank Joseph claimed that copper was at the heart of Atlantean wealth. He further maintained that a major source of this copper was the Michigan North Peninsula from where millions of pounds of the metal were extracted. Conventional wisdom has never explained the source of the vast quantities of copper required to feed the needs of the European Bronze Age. Researchers, such as Joseph, are convinced that the abandoned Michigan mines were exploited by pre-Columbian trans-Atlantic mariners, possibly Atlanteans, in order to satisfy the demands of the Mediterranean Bronze industry.
A 2014 paper by David Hoffman offers an interesting history of the Michigan copper story from 1536 until 1879(e). Adding to that is the early claim in 1867, by Bishop Patrick Nieson Lynch of Charleston, South Carolina that the ancient exploitation of the Michigan copper had to be carried out by the Phoenicians.
A short paper in the Migration & Diffusion website(d) by Gerard Leduc in 2017, suggests a possible route that may have been used for the exportation of the Michigan copper to the Atlantic Ocean, before heading for the Mediterranean and/or Northern Europe.
Professor Ilias Mariolakos in a 2010 paper(c) supported the idea of Old World miners in Michigan, identifying prehistoric Greeks as participants.
In 1982, an ancient shipwreck was discovered near Uluburun in Turkey. On board were 10 tons of copper ingots whose purity led some to conclude that it could only have come from the Michigan mines. J.S. Wakefield has written a paper supporting this view(a), although he does not directly attribute this copper trade to Atlanteans.
However, Gavin Menzies in The Lost Empire of Atlantis claims that Minoan Crete was in fact Atlantis and that the Minoans not only discovered America but were also responsible for the extensive exploitation of the Michigan copper mines.
>Nevertheless, this remarkable claim was endorsed by science writer, Jeff Danner (f), who cites Plato’s reference to an ‘opposite continent’ as an allusion to America. More recent support has come from marine Captain, Richard deGrasse in his 2021 book, The Influence of Stonehenge on Minoan Navigation and Trade in Europe (g).<
It must be stated that this idea of the Michigan copper mining being the work of Old World traders is hotly disputed by local Michigan archaeologists(b).

James came to public attention when, in collaboration with Nick Thorpe, Nikos Kokkinos, Robert Morkot and John Frankish, he authored Centuries of Darkness  in which he explored the problems of the chronology of the Mediterranean and Near East in the second millennium BC. It generated much controversy, which continues as the authors’ website(c)(d) demonstrates.
The following years saw the production of an impressive three-volume work by David Rohl offering similar ideas on a New Chronology for the region. In fact, James and Rohl had collaborated until they had divergent views regarding the identification of the biblical Shishak, Rohl favouring Ramesses II, while James opted for Ramesses III.
James has also been studying the Atlantis question since the early 1970s. Paul Dunbavin recounts that James had originally favoured Megalithic Britain as Atlantis. Francis Hitching in The World Atlas of Mysteries notes how James calculated the date of the demise of Atlantis as 3600 BC. He arrives at this by accepting the commonly agreed date for the beginning of Egyptian civilisation of 3100 BC. He then adds the 1,000 years, which Solon was told by the Egyptian priests, was the time that had elapsed between the Atlantean Athenian war and then arbitrarily subtracts 500 years to compensate for an assumed nationalistic exaggeration of Egypt’s antiquity; a habit common to many ancient kingdoms.
However, when he finally published his work on the subject, The Sunken Kingdom , he controversially offered a site in Anatolia in western Turkey as his preferred location for Atlantis. Unfortunately, he has been unable to obtain permission from the authorities to dig at the site and hopefully substantiate his theory. The book is supported by a website(a).
>A few years earlier, Eberhard Zangger published The Flood From Heaven, in which he also placed Atlantis in western Anatolia, specifically in Troy. James offers a few critical comments including what he considers a major weakness in Zangger’s theory, namely that Troy did not ‘sink beneath the waves in a single day and a night’. [p.201]<
James was highly vocal in disputing the dendrochronological dating of the Uluburun shipwreck discovered in 1982 off southwestern Turkey. The initial date given was 1315 BC, later revised to 1305 BC but due to a lack of bark on the piece of wood tested a definitive date was impossible. Even if the bark had been attached it would still only have provided the date that the tree had been felled not the date of the shipwreck(b). Subsequently, the more imprecise radiocarbon dating gave a date of ‘around’ 1300 BC.
James is also co-author, again with Nick Thorpe, of Ancient Inventions , which is a 672-page tome that offers a fascinating account of the inventive capabilities of ancient civilisations. In this 1994 book, he comments that “Plato’s yarn is largely a work of fiction” [p.455], >which makes you wonder why, just a year later, he published The Sunken Kingdom!<
Gavin Menzies (1937-2020<) is a former submarine officer with the British Navy. He retired in 1970, a year after an incident in the Philipines in which the boat under his command collided with the USS Endurance. He followed this with a brief dalliance with British politics.
However, Menzies is best known as a controversial author beginning with 1421: The Year China Discovered the Worldand six years later 1434: The Year a Magnificent Chinese Fleet Sailed to Italy and Ignited the Renaissance. His theories have been shown to be heavily flawed(a) and Menzies himself was accused of being either “a charlatan or a cretin” (b).
The badarchaeology website has, understandably, also given a thumbs-down to Menzies’s work(l).
In his book, 1421, Menzies speculated that the Chinese fleet suffered damage during a storm and landed at Bimini where they used their large square ballast stones to build an emergency dry dock, the remains of which are now the Bimini Road!
However, the idea of ancient Chinese in America was proposed as early as 1913, following discoveries(k) just 19 miles from Mexico City, speculatively dated to around 3000 BC! Similar claims have been made throughout the ensuing century, with John A Ruskamp Jnr. one of the most recent.
Another, well-illustrated site(d), accuses Menzies of altering maps to suit his theory.
April 16th 2010 saw the inventive Mr Menzies present his latest offering, The Lost Treasures of Atlantis, at the Royal Geographical Society in London before its formal publication in August. The title was later changed to The Lost Empire of Atlantis.
He argued that the Minoans discovered America 4,000 years ago and that an ancient trading empire had stretched from the North American Great Lakes to Kerala in India.
I should point out that Roger Jewell had previously identified a Minoan connection with the Michigan copper mines in a 2000 book.
Menzies bases his thesis on metallurgy, ancient shipbuilding and navigation techniques as well as DNA evidence. He focuses on the cargo found on the Uluburun shipwreck(c) found off the coast of Turkey and which is dated to the 14th century BC.
My principal reaction to his book was that he seemed to studiously avoid Plato’s text as a source of information. Perhaps, because much of what Plato said does not conform to Menzies’ imaginative theories. He identifies Thera as the location of the capital of Atlantis but he does not attempt to explain why Plato did not simply say so, since Thera was less than 150 miles from Athens and well known to the Athenians. Furthermore, Menzies places the ‘Pillars of Heracles’ at Gibraltar but then fails to explain how the Atlanteans could have attacked them from BEYOND the ‘Pillars’ if Atlantis was virtually on their doorstep on Crete.
He contends that the Minoans (Atlanteans) discovered America, exported vast quantities of copper from Michigan(g) via the Mississippi and after processing it at Poverty Point sent it to the Mediterranean to feed the needs of the Bronze industries there. He attributes the building of astronomical stone circles in the Mediterranean as well as Spain, Brittany and the British Isles to the Minoan influence. However, none are found on Crete! It is understandable therefore that his book has received some very bad reviews(e)(f).
This is a speculative book about the Minoan civilisation and has little to do with Atlantis apart from the cynical use of its name on the cover. However, Menzies does have many followers(g), but Jason Colavito’s seven-part critique(h) of his book that should be compulsory reading for those fans.
In October 2013 Menzies returned to the subject of ancient sea voyages and in particular the very early visitors to the Americas in Who Discovered America?  Judging by the first customer reviews(i) this offering promises to be as controversial as his previous books. Two of his specific claims are that transoceanic travel began 100,000 years ago and that the Chinese regularly began visiting America from 2200 BC!
Recently, in 2015, new evidence of early Chinese in America was found by John A. Ruskamp Jnr. in Albuquerque’s Petroglyph National Monument(j). Ruskamp has already identified 82 archaic Chinese petroglyphs, many dated to the Shang dynasty circa 1042 BC.
>Despite his death in 2020, his studies have been continued by the 1421 Foundation(m).<
