The Cantino Planisphere

Completed by an unknown Portuguese cartographer in 1502, the Cantino Planisphere is one of the most precious cartographic documents of all times. It depicts the world, as it became known to the Europeans after the great exploration voyages at the end of the 15th and beginning of the 16th century to the Americas, Africa and India. The West Coast of  the Americas was completely unknown and the North America West Coast would not see settlers till the Portola Expedition of 1769.
