was correct had not been resolved at the time, both were represented on the same map. Both extremities of the map represent the eastern extremity of Asia, according to the two alternative theories. As Nunn said, "This was a very plausible way of presenting a problem at the time insoluble." As noted by Nunn, the distance between the meridians on the map is different going eastward and westward from the prime meridian which passes through the Fortunate Isles (Canary Islands). This has the effect of representing the eastern coast of Asia twice: once in accordance with Ptolemy's longitudes to show it as Martin Behaim had done on his 1492 globe; and again in accordance with Columbus' calculation of longitudes to show his and the other Spanish navigators' discoveries across the Western Ocean, which Columbus and his followers considered to be part of India Superior. On his 1516 world map, the Carta Marina, Waldseemüller identified the land he had called Parias on his 1507 map as Terra de Cuba and said it was part of Asia (Asie partis); that is, he explicitly identified the land discovered by Columbus as the eastern part of Asia. Globe gores Besides Universalis Cosmographia, Waldseemüller published a set of gores for constructing globes. The gores, also containing the inscription America, are believed to have been printed in the same year as the wall map, since Waldseemüller mentions them in the introduction to his Cosmographiæ Introductio. On the globe gores, the sea to the west of the notional American west coast is named the Occeanus Occidentalis, that is, the Western or Atlantic Ocean, and where it merges with the Oceanus Orientalis (the Eastern, or Indian Ocean) is hidden by the latitude staff. This appears to indicate uncertainty as to America's location, whether it was an island continent in the Atlantic (Western Ocean) or in fact the great peninsula of India Superior shown on earlier maps, such as the 1489 map of the world by Martellus or the 1492 globe of Behaim. Only few copies of the globe gores are extant. The first to be rediscovered was found in 1871 and is now in the James Ford Bell Library of the University of Minnesota. Another copy was found inside a Ptolemy atlas and had been in the Bavarian State Library in Munich since 1990. The Library recognized in February 2018, after reviewing its authenticity, that this map is
