In 1929 a map was found. The document was drawn in 1513 by Piri Reis, an admiral of the Turkish fleet in the sixteenth century. It shows the western coast of Africa, the eastern coast of South America, and the northern coast of Antarctica. The Antarctic coastline 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.
