The Waldseemüller map, Universalis Cosmographia, is a printed wall map of the world by German cartographer Martin Waldseemüller, originally published in April 1507. It is known as the first map to use the name "America". Its main map, and his globe gores of the same date, depict the American continents in two pieces. These depictions differ from the small inset map in the top border, which shows the two American continents joined by an isthmus. The name America is placed on what is now called South America on the main map, this being the first map known to use this name. As explained in Cosmographiae Introductio, the name was bestowed in honor of the Italian Amerigo Vespucci. The map is drafted on a modification of Ptolemy's second projection, expanded to accommodate the Americas and the high latitudes. A single copy of the map survives, presently housed at the Library of Congress in Washington, D.C. Waldseemüller also created globe gores, printed maps designed to be cut out and pasted onto spheres to form globes of the Earth.
The wall map consists of twelve sections printed from woodcuts measuring 18 by 24.5 inches (46 cm × 62 cm). Each section is one of four horizontally and three vertically, when assembled. The map uses a modified Ptolemaic map projection with curved meridians to depict the entire surface of the Earth. In the upper-mid part of the main map there is inset another, miniature world map representing to some extent an alternative view of the world.
The full title of the map is Universalis cosmographia secundum Ptholomaei traditionem et Americi Vespucii aliorumque lustrationes (The Universal Cosmography according to the Tradition of Ptolemy and the Discoveries of Amerigo Vespucci and others). One of the "others" was Christopher Columbus. The title signalled his intention to combine or harmonize in a unified cosmographic depiction the traditional Ptolemaic geography of Europe, Asia and Africa with the new geographical information provided by Amerigo Vespucci and his fellow discoverers of lands in the western hemisphere. He explained:"In designing the sheets of our world-map we have not followed Ptolemy in every respect, particularly as regards the new lands… We have therefore followed, on the flat map, Ptolemy, except for the new lands and some other things, but on the solid globe, which accompanies the flat map, the description of Amerigo that is appended hereto".
