Keith M. Hunter is described on the Ancient Origins website as “an independent researcher with degrees in Psychology and Sociology, who has delved into the mysteries surrounding the origins of sacred measures, and of the base-60 mathematical system of the ancient Sumerians and Babylonians.”
He is the self-published author of The Lost Age of High Knowledge: Evidence of an Advanced Civilisation Prior to Recorded History [2097], which built on the work of Bruce Cathie!
Hunter also maintains the Lost Age Secrets website(a). In it, he strongly endorses
the location theory of Matthew Chinn, who places Atlantis in the Azores region(b).
