Fourth Part of the World
This is a fascinating account of Europe's growing awareness during the Medieval and Renaissance periods that a fourth part of the world existed outside of the known three - Europe, Asia, and Africa. The story is told by examining and exploring an influential but subsequently lost map produced in 1507. It was the first to use the word "America" to name the new part of the world, which had recently been discovered by - was it Columbus, or Amerigo Vespucci? The map also was the first to show an ocean to the west of that new world. The lost map was found in Germany early in the 20th century, and was transferred at great expense a few years ago to the Library of Congress, where it is now on display.
