Ancient Navigation: The Piri-Reis Map

Potentially one of the most significant finds in modern time. The Piri-reis map (c. 1513), shows the coastlines of the American continent. It also includes the outline of the Antarctic continent which has been frozen over since around 4,000 BC. This map alters all previous conceptions of our pre-historic ancestors abilities. The 'Piri-Reis' map (c. 1513). is one of several 'portellano's', which appear to have a geometric basis of unknown provenance.

This map has many interesting features, such as:

The map has  pre-Columbian provenance.

The map shows the coastline of America.

The map shows accurate use of Longitude and Latitude.

The map-builders used 'Spherical geometry'.

The centre of the map is at the junction of the 23.5˚ parallel and the longitude of Alexandria.
