Carte Pisane Navigational Map

Carte Pisane Navigational Map

This map shows the whole Mediterranean, the Black Sea and a part of the Atlantic coast, from the north of present-day Morocco to the present-day Netherlands, but the accuracy of the map is mostly limited to the Mediterranean. It is the oldest known surviving nautical chart, thought to have been made in the late 13th century. It was found in Pisa, hence its name.
The slide is annotated "The oldest Portolano known as the "Carte Pisane"
