The Piri Reis map is a world map compiled in 1513 by the Ottoman admiral and cartographer Piri Reis. Approximately one third of the map survives, housed in the Topkapı Palace in Istanbul. After the empire's 1517 conquest of Egypt, Piri Reis presented the 1513 world map to Ottoman Sultan Selim I. It is unknown how Selim used the map, if at all, as it vanished from history until its rediscovery centuries later.
