Luciano Chiereghin is an Italian researcher who has a great interest in the history of the Po Valley, both ancient and modern. In his 2007 book Atlantide al Microscopio (Atlantis Under the Microscope) he has the plain of the Valley as the location of Atlantis (=Hyperborea) and specifically the ancient town of Adria. He also proposes that Majorca, Sardinia, Corsica, Sicily, Crete and the Peloponnese constituted the island territories of Atlantis.
However, he is not the only one to link this region with Atlantis, as Morven Robertson published a book in 2015 with a similar theme. Both authors were drawn to the Po Valley by its size and its proximity to the magnificent mountains of the Alps, which protect the plain from the northern winds.
Diego Marin has favourably reviewed Chiereghin’s book(a).
Morven Robertson (1954- ) is a British scientist and author of About Atlantis: Finding the Lost City of Atlantis in which be proposes that Atlantis had been situated in the Po Valley of Northern Italy, specifically between Padua and Ferrara. He points out that the plain of the Po valley is surrounded on three sides by mountains. He speculates that the Atlantean confederation consisted of kingdoms both within and without the Mediterranean, which is my main bone of contention, namely too much speculation. While his theory, in common with many others, matches many of the details provided by Plato, it does not conform to enough of them. I find his idea of such a widely separated Atlantean alliance, not credible as Plato clearly describes a culturally coherent grouping, sharing language, script and religion. The Po Valley is not to the west of either Athens or Egypt and in addition Robertson glosses over the matter of the elephants, which has caused so much difficulty for other researchers.
