Dr. Albert Gruhn was reported to have placed Atlantis in the Western Mediterranean Basin, according to a report in New Zealand’s North Otago Times of August 8th 1911(a). Apparently it was quoting from the ‘North German Gazette’ where he stated his belief that the Western Basin had once been dry land and that Atlantis had been situated between the Balearic Islands and Sardinia or in what is now the Tyrrhenian Sea.
A couple of years earlier he had disputed(b) that Homer’s Troy had been located at Hissarlik, instead he opted for Duden.
Heinrich-Julius von Klaproth (1783-1835) was a German orientalist who suggested that Atlantis had been a large island that nearly filled the western Mediterranean basin. He produced a speculative map of this island, which he referred to as Tirrenide (from Tyrrhenia), a term he used to describe the combined and expanded landmasses of Corsica, Sardinia and Menorca. Tirrenide is usually applied to the Italian mainland extended to include Corsica and Sardinia.
