“Originally developed as a navigational tool for ships, the Mercator map is valuable because it shows certain nautical routes (so-called “rhumb lines”) as straight lines, and can be published to fill a neatly portable, rectangular sheet of paper. As a consequence of showing the round earth in this flattened format, the most popular version of the Mercator map shrinks the size of Africa, inflates the size of Greenland, makes North “up” and South “down,” slices off a piece of Russia, and shows the Atlantic shipping lanes between Europe and America as the center of the world. ”
