The Cosmographiae introductio, written by Martin Waldseemüller and Matthias Ringmann and printed in St. Dié, France, in 1507, was meant to be a guidebook to Waldseemüller’s 1507 world map, the Universalis cosmographiae.  The text describes the necessary geographic and cartographic information that a viewer would need in order to understand Waldseemüller’s representation of the world.  In it, Waldseemüller and Ringmann also describe their reasons for naming the New World “America” after Amerigo Vespucci.
