Ahmed Muhiddin Piri (1465–1553) better known as Piri Reis. He is primarily known today for his maps and charts collected in his Kitab-ı Bahriye (Book of Navigation), a book that contains detailed information on navigation.In 1929, a group of historians found an amazing map drawn on a gazelle skin. Piri Reis high rank within the Turkish navy allowed him to have a privileged access to the Imperial Library of Constantinople. The Turkish admiral admits, in a series of notes on the map, that he compiled and copied the data from a large number of source maps, some of which dated back to the fourth century BC or earlier. The Piri Reis map shows the western coast of Africa, the eastern coast of South America, and the northern coast of Antarctica ice free. The northern coastline of Antarctica is perfectly detailed. The most puzzling however is not so much how the Piri Reis Antarctica map managed to so accurate 300 years before it was discovered, but that the map shows the real coastline under the ice. Geological evidence confirms that the latest date Queen Maud Land could have been charted in an ice-free state is 4000 BC. The official science has been saying all along that the ice-cap which covers the Antarctic is million years old. The Piri Reis Antarctica map shows that the northern part of that continent has been mapped before the ice did cover it.
