Sir John Chardin
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.
