Sylvain Tristan is a young French researcher who has adopted the theories of Jean Deruelle, who advocated the idea that the Atlanteans were in fact the Megalith Builders of the Bronze Age who left us a legacy of remarkable structures from Scandinavia, along the Atlantic seaboard including the British Isles and on down into the Mediterranean as far as Malta. Tristan also subscribes to Deruelle’s contention that the capital of this civilisation had been located on the Dogger Bank in the North Sea, between England and Denmark.
A second major influence on Tristan’s thinking was the writings of Alan Butler, who among other matters, has argued for the use of 366-degree geometry by the Megalith Builders. Butler wrote the Foreword to Tristan’s Les Lignes d’or, it can be read on Tristan’s English language website(b), while the French text of the book is available online(e).
Tristan returned to the subject of 366-degree geometry in his latest book, Numbers of the Gods.
An interview with Tristan can be accessed on the Internet(a). Unfortunately, his non-fiction output has only been published in French so far, but in 2012 he published, The Divine Number, in English, as a Kindle book(c). This novel is based on a series of secrets associated with the 366-degree geometry of Butler’s research. He introduces the book in a short YouTube clip(d).
Tristan’s idea of a megalithic Atlantis has been heavily criticised by Alain Moreau(f).
