Piri Reis map cut apart by Occam's Razor

Piri Reis was a Turkish cartographer. One of his maps has become famous for allegedly depicting an iceless Antarctica, and lends evidence to the existence of ancient, advanced civilizations going back as far as 15,000 years.
This theory in conjunction with ideas about pole shifts were advanced by one Charles Hapgood.

Diego Cuoghi shows us that it is more likely that the map is the result of inaccurate source material, some wild guessing, and some politically motivated cartography by some Portugese map makers concerning 'la Raya'.
