Quest for Atlantis*  by R. Cedric Leonard is a work in which he advocates a Mid-Atlantic Ridge location for Atlantis and identifies Cro-Magnon Man as Atlantean with links to ancient Egypt. He devotes a considerable space to a discourse on ancient alphabets and scripts such as is found on the Glozel Tablets and their possible connection with Atlantis. Unfortunately, the author also extends his study into the matter of ancient Sanskrit accounts of flying machines, which does little to identify the location of Atlantis. Leonard also maintained a website that supported this book and its more recent revised version.
Leonard has now retired and most links to his papers are broken.
*Not to be confused with The Quest for Atlantis by John Stewart Bowman
