In his globe Waldseemüller followed the printed Ptolemy maps of his time by placing zero longitude in the Fortunate Islands (Canary Islands).
Waldseemüller's globe extends eastwards from zero longitude to 360 degrees, the first map known to show the whole earth.
Ptolemy's world map depicted only 180 degrees of longitude, the extent of the world known to him.
