Sergio Frau was born in 1949 and is a journalist with Italy’s leading daily newspaper La Repubblica. He is also the author of a hefty 672 page volume, Le Collone de Ercole: Un’inchiesta that firmly places Atlantis in Sardinia and the Pillars of Hercules in the Strait of Sicily between Tunisia and Sicily. He supports this contention with references to ancient writers such as Herodotus and Dicaearchus.
Frau contends that a catastrophic inundation of some sort destroyed the mysterious ancient civilisation on Sardinia known as the Nuraghi, after whom the numerous ancient towers on the islands are named. A megatsunami around 1200 BC is accepted to have struck from the south. Frau believes that some of the survivors migrated to the Italian mainland and founded the Etruscan civilisation, while others formed part of the Sea Peoples who attacked Egypt.
His book sold over 30,000 copies in Italy, his theory received favourable attention from UNESCO and an exhibition based on his work has been shown in Paris and Rome. This is in sharp contrast to the 250 historians who reportedly denounced his theory. Then there are many others, such as Hannah Fielding, the novelist, who is very attracted to Frau’s ideas(b).
Robert Ishoy proposed a similar theory(a) on the Internet at least two years before Frau had his book published. However, the earliest claim that Atlantis had existed on Sardinia was made in 1982 by Paolo Valente Poddighe, who now accuses Frau of plagiarism.
Although the media have generally given a positive response to Frau’s book, Thorwald C. Franke has panned it, denouncing it as pseudo-science(d), but reluctantly conceded that Frau “could nevertheless be partially right! For the record, I agree with Franke’s limited support.
In addition to which, 71 Sardinian archaeologists, geologists and historians have signed a 21-point refutation of Frau’s theory(e).
So far Frau’s book is only available in Italian and German(c).*In 2017, Frau published a sequel to his Le Collone de Ercole, entitled Omphalos in which he expands on aspects of his Sardinian location for Atlantis in a hefty 1154-page volume, which once again is currently only available in Italian.*
In August 2016, Frau received another round of publicity following an interview with Sputnik news media(f). The interview added nothing of consequence, although the text was copied by other media outlets. Nevertheless, this did not hold back Jason Colavito from his standard atlantiphobic attack(g).
