Waldseemüller map

The Waldseemüller map or Universalis Cosmographia ("Universal Cosmography") 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". The name America is placed on South America on the main map. 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, 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 of the wall map, which shows the two American continents joined by an isthmus. The map was meant to document and update new geographical knowledge from the discoveries of the late fifteenth and the first years of the sixteenth centuries. It consists of twelve sections printed from woodcuts measuring . 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. Longitudes, which were difficult to determine at the time, are given in terms of degrees east from the Fortunate Islands (considered by Claudius Ptolemy as the westernmost known land) which Waldseemüller locates at the Canary Islands. The longitudes of eastern Asian places are too great. Latitudes, which were easy to determine, are also quite far off. For example, "Serraleona" (Sierra Leone, true latitude about 9°N) is placed south of the equator, and the Cape of Good Hope (true latitude 35°S) is placed at 50°S.
