David Wood ( -2012), was a surveyor and cartographer, and was the author of Genisis, which provides what he believed, is a mathematical solution to the mystery of Rennes-le-Chateau. Using his knowledge of ‘sacred’ geometry he concluded that Atlantis was located at 42°55´N 26°06´W (p.262), which is just north of the Azores in the Atlantic. He concludes that the survivors of Atlantis settled in the countries bordering the ocean after its destruction in 9000 BC or earlier.
Wood co-authored Geneset , a sequel to Genisis, with Ian Wallace Campbell, in 1994. This is a further study of the Rennes-le-Chateau mystery.
An extensive synopsis and review of both books is available online(a).
