Cogent? The letter-writer was arguing that the map was drawn from information extracted when Antarctica was “very hot” and iceless, way way before any human conceived of a map. If that’s cogent and backed-up research to you, no wonder you’re sticking up for this nonsense.
I wasn’t talking about the letter writer.
Which seems to conclusively prove that he may have drawn this in the 16 century, but a lot of it is based on much older information.
Which is hardly what you say he said...
