The bottom portion of the Piri Reis map has been proven to depict the continuation of the Argentine coast turned sideways to save space.
Absolutely and really nothing to see here. Totally bogus.
I’m completely willing to believe that it’s bogus. But that said... it’s the southern coast (the Argentine coast) that really doesn’t match. It sees forced, even allowing for the usual longitudinal distortion. The features in the Piri map don’t really match up with the features in the coastline.
Has anybody done a similar feature matching for the Antarctic coast? Seems that would settle the matter.
