Paolo Valente Poddighe is an Italian researcher who claims to have been the first to have identified Sardinia as the location of Atlantis in 1982. This was long before Robert Ishoy proposed the same on his website and even longer before Sergio Frau published his 2002 book with an identical claim. This led to accusations of plagiarism by Poddighe, who only then published his own book, Atlantide Sardegna:Isola dei Faraoni ^[711] (Atlantis Sardinia: Island of the Pharaohs).

Where Frau locates the Pillars of Heracles at the Strait of Sicily, Poddighe opted for the Strait of Bonifacio between Sardinia and Corsica.
