The Piri Reis World Map.
The Piri Reis World Map of 1513 was discovered in 1929. It’s a portolan-style world map created when positioning recently discovered places was almost technically impossible. It succeeded in producing a detailed and considerably accurate depiction of the coastline and islands of the newly discovered regions of the world and formed a circular map designed on a hypothetical center with a rich variety of illustrations. It represents the earliest cartographic record of Columbus’s oceanic voyages (New World discoveries), is among the earliest work showing Terra Australis (the first map to depict its unique fauna), and stands out with distinction among the maps of the Age of Discoveries.
