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!*
