<P> The Piri Reis map is a world map compiled in 1513 from military intelligence by the Ottoman admiral and cartographer Piri Reis (pronounced (piɾi ɾeis)). Approximately one third of the map survives; it shows the western coasts of Europe and North Africa and the coast of Brazil with reasonable accuracy . Various Atlantic islands, including the Azores and Canary Islands, are depicted, as is the mythical island of Antillia and possibly Japan . </P> <P> The map's historical importance lies in its demonstration of the extent of global exploration of the New World by approximately 1510, and in its claim to have used a map of Christopher Columbus, otherwise lost, as a source . Piri also stated that he had used ten Arab sources and four Indian maps sourced from the Portuguese . More recently, the map has been the focus of pseudohistoric claims for the pre-modern exploration of the Antarctic coast . </P>
