In my previous message an error occurred when I wrote the words Holy Earth instead of Hollow Earth, not a casual lapsus: in the quoted chapter of "Rivolta", Evola notes the correspondence of the symbols of Centre, Pole, Lost Island, City of the North (Tshang Chambhala), White Island (Avalon) and so on. Anyway, since Evola, like Wirth, seems to have in mind mostly a concrete polar location, it is permitted to interpret the "underground" home or provenance (for instance by Miguel Serrano who suggests the Antarctica) as a misunderstanding of a vision that in UR-KRUR is called "sub specie interioritatis"; maybe the same considerations could apply to the "physical" submersion of Atlantis.
Evola, at the end of that chapter, is referring just to "a law of solidarity between physical and spiritual causes" and the result was the age of the wolf began when "the polar abode became deserted".
