Another featured photo from Wikipedia: the Cantino planisphere, a map completed by an unknown Portuguese cartographer in 1502, during the European Age of Discovery. It depicts the world as it became known to the Europeans after voyages to the Americas, Africa, and India.
It is considered one of the most valuable cartographic documents of all time, displaying a remarkable degree of accuracy for its period, and being the oldest surviving map to show Europe’s early geographic discoveries. It provides us with unique historical information about the way maritime exploration was conducted and how nautical cartography evolved.
It is now kept in the Biblioteca Universitaria Estense, Modena, Italy.
