The Piri Reis Map of 1513 is the first surviving map that shows the Americas (the Vinland map may be older but only shows a part of North America). The Piri Reis map shows North America, South America, Greenland and Antarctica which had not yet been discovered. The map was made by a Turkish Admiral Piri Ibn Haji Mehmed. Reis means admiral. Piri Reis did not long bath in the light of this famous work but was beheaded in 1554 for an unsuccessful foray into the Persian Gulf. The map became lost and was only rediscovered in 1929 by a group of historians working in the harem section of the Topkapi Palace in Istanbul (Constatinople) found the map in a pile of rubble.
Because of the details on this map, many claims have been made for this map. Some even believe that it is so perfect that it could only have been made from very high altitude photographs.
