Alan Baker (1964- ) is an English author with a mixed output of both non-fiction as well as some fiction. His chief interest would appear to be historical mysteries, which led to the publication of The Enigmas of History. This book touches on a number of subjects covered on this site; Noah‘s Deluge, Stonhenge, Amazons and, of course, Atlantis. He briefly discusses a few of the more popular theories; Bimini, Thera, and the Atlantic, but arrives at no firm conclusion, although he appears sympathetic to its existence. In his Destination Earth he delves into the disappearance of Percy Fawcett and the mysteries relating to South America.
Colonel Percy Harrison Fawcett (1867-1925?) was a retired military engineer with a great interest in archaeology. Fawcett, who published a number of articles in The Occult Review, believed in the existence of Atlantis and was convinced that he could find a remnant of its advanced population(c) .Inspired by stories of lost cities in the Amazonian jungle he was convinced that Brazil had been the home to a city that had been a colony of Atlantis. His ambition was to discover the location of this city, which he referred to as ‘Z’, and so prove the reality of Atlantis. Alan Baker recounts[1031.121] how in 1924 Fawcett wrote to Lewis Spence outlining his theory that this lost city had been home to white-skinned refugees from Atlantis. Undaunted by an earlier failed expedition, in 1925 he led a second attempt, partly sponsored by the Royal Geographical Society, into the Matto Grosso and disappeared without trace(a). A book by David Grann, The Lost City of Z, was published in 2009. There is a film produced by and starring Brad Pitt as Fawcett and his search for Z on release now (2017) and also entitled The City of Z.
The Russian researcher, Oleg Dyakonov, has written an extensive paper(d) on Fawcett, his expeditions, achievements and his critics. It is in Portuguese, but translates well with Google.
