Nautical explorations played a major role in the renaissance of map-making. The problem of representing the spherical earth on a flat sheet of paper led to new types of map projection for use by navigators at sea. The Greek astronomer Ptolemy, the Portuguese cosmographer Pedro Nunes, the Flemish cartographer Gerard Mercator and his friend Abraham Ortelius all played a role in this story.

The first ‘modern’ maps of the world were due to Gerard Mercator (1512–1594), obtained by projecting the sphere outwards on to a vertical cylinder and then stretching the map in the vertical direction in such a way that the lines of latitude (horizontal) and longitude (vertical) appeared as straight lines and all the angles (compass directions) were correct, as on the Canadian stamp. The word ‘atlas’ was coined by Mercator for his three-volume collection of maps in 1585–1595.
