Ferdinand Gidon (1874-1944), was a French medical historian, who proposed over seventy years ago  the existence of a Bronze Age Atlantis on the Celtic Shelf near Britain. He dated this inundation to between 3000 and 1200 BC. However, this date is too late as the area had already been submerged for some thousands of years during an event known as the Flandrian Transgression, which began around 7000 BC. A further problem with his theory is that since Atlantis, according to Plato, contained mountains, the submersion of the relatively shallow Celtic Shelf would at least have left their peaks still visible, a feature missing from the Celtic Shelf.
Gidon also translated from German and Spanish respectively some of the work of Leo Frobenius  as well as that of Vivante & Imbelloni .
Brittany in northwestern France is sometimes referred to as Little or Lesser Britain. It is one of the most exciting regions of Megalithic Europe. The stone rows of Carnac are unequalled, Le Grand Menhir Brisé was once the largest standing stone in Europe, while Morbihan contains a huge number of dolmens and standing stones.2019 saw a report that “Bettina Schulz Paulsson, an archaeologist at the University of Gothenburg, reexamined some 2,410 radiocarbon dating results that have been assigned to Europe’s megaliths and put them through a Bayesian statistical analysis. Based on the picture the data present, Schulz Paulsson believes that the megaliths were first constructed by dwellers of northwest France during the second half of the fifth millennium BC.” (b) >Both Robert Hensey, who has studied and written about Newgrange [1766.6]<and Mike Parker Pearson, Stonehenge’s leading, authority, have endorsed this idea of a French origin for megalith building(c).
The earliest suggestion that Atlantis may have been the connected with the Armorican peninsula came from François Gidon in the 1930’s when he proposed that Atlantis had been situated on an exposed Celtic Shelf stretching from Brittany to Ireland. Unfortunately, he dates the submergence of this land to between 3000 and 1200 BC, which was millennia after that part of the Celtic Shelf had been inundated by the Flandrian Transgression.
Jean Markle was convinced that the Carnac stone were connected with Atlantis. Recently, Sylvain Tristan followed the work of Jean Deruelle in supporting a megalithic Atlantis. Further support has come from Alfred deGrazia and Helmut Tributsch who saw Megalithic Europe as Atlantis with the island of Gavrinis in Brittany as its capital.
The American researcher, Hank Harrison, considers the Morbihan départment as a significant Atlantean location if not the home of its capital.
Reinoud deJonge proposes even greater significance for the Brittany megaliths with his claim that they record the Flood of Noah in 2344 BC(a).
