I love books like this, where the author takes something seemingly small or insignificant and weaves a vast tapestry around it. In this case, we have a single map, but it’s an important one. The Waldseemuller map, made by a couple of German scholars, was the first map to designate the “New World” as something separate from Asia. Not important? Well, the Library of Congress thought otherwise. It bought the map in 2003 for an unprecedented 10 million dollars.
