Macoratti, Paolo
Paolo Macoratti is an Italian architect who is quoted by Sergio Frau, in his highly publicised book, as identifying sites in southern Sardinia as the locations of the plain and city of Atlantis.
Macoratti’s map shows the Plain of Atlantis as a green quadrangle with the green circle to the south in the Gulf of Cagliari as his preferred site for the city of Atlantis.
Mario Cabriolu, another Frau supporter, has endeavoured(a) to improve on Macoratti’s interpretation.
