Peter Marsh is a keen diffusionist with a particular interest in the peoples of the Pacific(a). However, this has not precluded him from looking at the Atlantic, where he concluded that the Azores were most likely remnants of Atlantis based on Plato's description(b).
*He takes Plato’s Atlantis account at face value and accepts that it flourished around 9,500 BC. Additionally, in chapter 10 of his website, he refers to the Michigan copper mines and surmises that they were transported to Europe by Phoenicians and Berbers!*
John Macmillan Brown (1845-1935) although Scottish by birth, he spent his academic life in New Zealand where he was a professor of Classics and English at Canterbury College in Christchurch.*He had an enlightened attitude towards the education of women.*
In 1924 he published Riddle of the Pacific in which he expressed the view that there had been a continent in the Pacific with some of today’s island groups its only remnants. This was some years before James Churchward started publishing his books on Mu.
Jean-Benjamin De LaBorde (1734-1794) was best known as a musician from the age of 14, but was also a historian and cartographer(a) . In his Histoire abregeee de la Mer du Sud, it appears he was the first to suggest a sunken continent in the South Pacific with New Zealand and other island groups being today’s remnants of Plato’s lost land.
Unfortunately, his musical and scientific interests were curtailed when his association with Louis XV led him to the guillotine.
Louis-Claude Vincent (1906-1988) was a French hydrologist who is probably best known for his foray into the field of alternative medicine when he developed his theory of bio-electronics. In 1969, with unexpected incongruity, he published two large volumes (800 pages) on the origins of civilisation entitled Le paradis perdu de Mu (The Lost Paradise of Mu). He claimed that an impact with an extraterrestrial body changed the axis of rotation of the Earth by 90° causing the Deluge and submerging Atlantis in the Pacific.
