In 1929, a group of historians found an amazing map drawn on a gazelle skin.
Research showed that it was a genuine document drawn in 1513 by Piri Reis, a famous admiral of the Turkish fleet in the sixteenth century.
His passion was cartography. His 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. The northern coastline of Antarctica is perfectly detailed. The most puzzling however is not so much how Piri Reis managed to draw such an accurate map of the Antarctic region 300 years before it was discovered, but that the map shows the 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.
On 6th July 1960 the U. S. Air Force responded to Prof. Charles H. Hapgood of Keene College, specifically to his request for an evaluation of the ancient Piri Reis Map:
