This nautical world map, engraved by Girolamo Porro, was one of two world maps included in Porcacchi's popular pocket-sized atlas. It covers most of the world, excluding far eastern Asia and the western coast of North America; thus alluding to a connection between the two. The Terra Incognita landmass dominates the bottom of the map. The handsome map is filled with rhumb lines and the seas are fully stippled. On a sheet of Italian text measuring 7.6 x 11.8".
