The Caucasus Mountains lie between the Black and Caspian Seas and contain the highest mountain in Europe, Mount Elbrus (Russia). In ancient times it was the location of several kingdoms of whom two were known as Albania and Iberia
Delisle de Sales was probably the first to suggest the Caucasus as the home of the original Atlantis, with refugees from there establishing Plato’s Atlantis in the Central Mediterranean. However, the greatest proponent of the Caucasus location for Atlantis was R.A. Fessenden who wrote an extensive multi-volume work  on the subject early in the 20th century.
More recently, Ronnie Gallagher, an admirer of Fessenden, has studied the Caucasus region, in particular, the hydrology of the Caspian Sea(a), where he identified strandlines up to 225 metres above sea level, which he considers to be evidence of a vast inland Eurasian sea at the end of the last Ice Age. In Azerbaijan, he also found cart ruts similar to those on Malta as well as stone circles on the Absheron Peninsula(b). Professor E. N. Badyukova has offered some critical comments regarding Gallagher’s claims(k).
Flinders Petrie also referenced Fessenden in his (1926) paper The Origins of the Book of the Dead(f), in which he concluded “that the cultural connections of the earliest Egyptians, as well as the physical descriptions in their mythology, point to the Caucasus region. When, further, we find there the names of the principal places of the mythology in their relative positions, it gives strong grounds for regarding that region as the homeland of the earliest civilisation of the Egyptians.”
A few years later, an article by M. A. Murray in Antiquity (Volume 15 – Issue 60 – Dec. 1941) noted that Petrie’s “opinion was based entirely on literary and philological evidence” resulting in archaeologists being slow to accept it. To partially counter this Murray offered two pieces of evidence in support of Petrie’s proposed Egyptian-Caucasus connection.(i)
However, I must point out that in 1874 Hyde Clarke delivered a paper to the Royal Anthropological Institute in which he claimed that the Colchians in the Caucasus had been an Egyptian colony(h). Clarke also employed language similarities to support his contention. So we can reasonably ask, who was right or were both Clarke and Flinders Petrie wrong?
A forum on Graham Hancock’s website offered some more discussion about an Egyptian link with the Caucasus(j).
The Amazons of Greek mythology are thought by some to have originated in the Caucasus and as late as 1671, Sir John Chardin reported that a tribe of Amazons existed in Georgia. Interestingly, a 19th-century photo shows two armed ladies from Armenia captioned as ‘Amazons of Armenia 1895’.
An added mystery was offered by Alexander Braghine, who recounted that “I was present when a former Russian officer of Georgian origin found himself able to talk with the natives of Vizcaya immediately upon his arrival in Northern Spain: he spoke Georgian, but the Basques understood this language.” [156.187]
Currently, Bruce Fenton has claimed the Caucasus as the home of giants. However, Jason Colavito has demonstrated the unreliability of his claims(c).
In the Krasnodar region of southern Russia hundreds (3,000 and counting) of dolmens are to be found on both sides of the Caucasus. Interestingly, they show a distinctive form of megalithic architecture(g).
I feel that the Caucasus will have a lot more to tell us.

Peter Jakubowski (1947- ) was born in Poland and after attaining a doctoral degree in physics he moved to Germany in 1985. His principal area of interest ‘is a complete refoundation of physics and its practical applications in modern industry’. His ideas are explained in his book, Naturics  and his website(a).
Jakubowski had devoted space on his website to air his thoughts regarding Atlantis but later removed them during a 2011 revamp of the site. He appears to closely follow the views of Axel Hausmann(c). He located Atlantis on Sicily and the Malta Plateau and explained that the circular features of the capital city were in fact the remnants of an asteroid impact crater.
Stelios Pavlou has noted that “In 2001, Jakubowski published Atlantis of the Neanderthals, in which he argues that Atlantis was a Neanderthal civilization that was destroyed in 4804 BC. After that, civilizations of [modern] man ruled. He also argues that all of humanity descended from Atlantis. It is unclear whether he means this in a spiritual, scientific, or physical sense. Jakubowski further claims that the people of Atlantis were [up to] about five or six meters tall.
The most recent revised edition of his book is dated February 2014 and draws extensively on the work of Colin Wilson. Jakubowski formerly supported the notion of Atlantis in Sicily and Malta. It is unclear if this is still the case as all mentions of Sicily and Malta were removed in the book’s recent revision.”(d)
>In 2014, coincidentally shortly after Wilson died, Jakubowski revised and expanded the 2001 paper into an ebook, Atlantis of the Neanderthals  with the subtitle of Colin Wilson Corrected. The book, available online(e), offers a review of Wilson’s Atlantis and the Kingdom of the Neanderthals . However, the purpose of the book seems to be to promote Jakubowski’s theories of ‘unified physics’ (naturics) rather than to criticise Wilson’s ideas.<
In 2016, Jakubowski sent an open letter(b) to Graham Hancock following the publication of Magicians of the Gods. In this somewhat rambling missive, he touches on the Younger Dryas, ancient giants and the evolution of human civilisation.
Denis Saurat (1890-1958) was born in Toulouse and educated in Britain and France. He was a professor of French literature and lectured in both countries. He also had a lifelong interest in the occult among a wide range of subjects. One of his conclusions was that the worldwide megalithic remains of prehistory are evidence for the existence of a race of giants in our dim and distant past. His books discuss this idea in detail including supporting hints from the Bible and then link the entire concept with Plato’s story of Atlantis. Saurat also suggested that the use of electricity in ancient Egypt produced gleaming eyes in the statues of Isis in her temples.>This suggestion of electricity in early Egypt was recently revisited by an engineer Andrew Hall in a YouTube video(b).<
Unfortunately, Saurat also seems to have borrowed many of the exotic concepts of Hans Hoerbiger such as a succession of moons crashing to earth. Saurat has added little to the solution of the Atlantis mystery.
He suggests two Atlantises, one about 30,000 years ago in the Andes around Lake Titicaca and the second 12,000 years ago described by Plato. Fortunately, Saurat is not arrogant and so in recognition of how scientific advances have a way of destroying previously held ‘certainties’, he admits in his summation (p118) that “despite all the evidence marshalled in this book, at no point can we say that we are absolutely sure.”
A further book deals with the religion of the giants.
In 2003 the Canadian author, John Robert Colombo published a biography of Saurat.
A blog(a) from Jason Colavito offers further details of Saurat’s daft ideas.
