Peter Tompkins (1919-2007) was an American journalist, WWII spy and perhaps best known as the author of the 1971 book, Secrets of the Great Pyramid which included an extensive appendix by Livio Catullo Stecchini on the relationship of Ancient Measures to the Great Pyramid.
Tompkins also wrote Mysteries of the Mexican Pyramids as well as over a score of other books on various ‘fringe’ subjects as well as his wartime exploits. He was interested in the mystery of Atlantis and to that end, he went to the Bahamas to study the ‘Bimini Road’ but concluded that it was only beach rock.
A later interview with Tompkins son, Ptolemy, revealed that his “dad was convinced that the Edgar Cayce readings about the rising of Atlantis were correct. He spent thousands and thousands of dollars photographing the limestone formations off Bimini – the so-called “Bimini Road.” My father loved the idea of Atlantis returning because he wanted the world to become a kind of new Eden. He was a true father of the New Age in this sense – he had the core New Age belief that the world once was, and would be again a better place. But not better in some mundane sense, but in the sense of being elevated back into a spiritualised condition that it had fallen away from. That’s what the Bimini stuff was all about” (a). Apparently, Tompkins left Bimini unconvinced that it had Atlantean credentials.
Tompkins wrote the foreword to the English translation of Otto Muck’s book, The Secret of Atlantis  and was impressed by Muck’s hypothesis of Atlantis in the Atlantic being destroyed by an asteroid and considered the work of Cesare Emiliani important in support of this contention.
>In the Preface to John Anthony West’s Serpent in the Sky , Tompkins wrote that “interestingly, West develops de Lubicz‘ notion that the Egyptian cosmology and understanding of this universe was not endemic to Egypt but came from colonists or refugees from Plato’s sunken continent of Atlantis, which could also explain the similarities and identities with the cosmologies of Central America, presumably brought there by other refugees from Atlantis”!<
As a ten-year-old, he witnessed how in the aftermath of the assassination of Reinhard Heydrich “a lot had changed. We were stuck at home, never leaving anywhere. Patrols were walking by, sometimes we heard some distant shooting, and then they began with the night searches. From apartment to apartment, from house to house, one after another. Wehrmacht, police, Gestapo. It ended up well at our house – they found nobody.” (a)
He wrote a volume debunking the more extreme ideas regarding the Bermuda Triangle. In 1978, he published, in Czech, Atlantis in the Light of Modern Research, while a few years later Earth Science Reviews (Vol.. 21, 1984) devoted a special issue of a revised version, in English, translated by Cesare Emiliani. Kukal favoured Santorini as the ‘inspiration’ behind the Atlantis story but as he stated, in a paper delivered to the 2005 Atlantis Conference on Melos, the story is fundamentally ‘pure fiction’.
Cesare Emiliani (1922-1995) was born in Bologna, Italy and is often referred to as the founder of paleoceanography. In 1975, at the University of Miami, Emiliani reported measuring deep-sea cores, taken from the Gulf of Mexico, that demonstrated a shockingly rapid rise of about 325 feet in the world’s sea level — a rate of metres per decade — around 11,600 years ago.>He suggested that the rupturing of Ice Dams at the end of the last Ice Age and the resulting floods may have given rise to worldwide flood myths, such as the biblical Deluge(a).<
When he also remarked casually that this was exactly the time Plato had given for the fall of Atlantis his offhand remark was met with severe comments from his peers.
In conversation with Peter Tompkins, he suggested that putative Atlantis sites such as the Azores, Spain and locations off the East Coast of the United States could all have been part of the Atlantean empire [802.193].
Emiliani was the translator of Zdenek Kukal’s book Atlantis in the Light of Modern Research (Earth Science Reviews Vol.21).
