Why the heck is “America” called “America” and not, say, “Columbia?” You’ll find the answer to that question and many more in Toby Lester‘s fascinating and terrifically readable new book The Fourth Part of the World: The Race to the Ends of the Earth, and the Epic Story of the Map That Gave America its Name (Free Press, 2009). As Toby points out, medieval Europeans thought the earth had three parts–Europe, Asia and Africa, with Jerusalem at the dead center and water all around. (And no, they didn’t think the earth was flat…). But in 1507 a peculiar item appeared–the Waldseemüller map– that outlined a fourth part of the world called “America,” with the Atlantic Ocean on the one side and an unnamed ocean on the other. Here’s the really curious thing though: at that time no European had ever seen what we now call the “Pacific Ocean.” Balboa was the first to see it, and he didn’t do so until 1513. So where did Waldseemüller and his colleagues get the idea that there was a continent between Europe and Asia and that an undiscovered ocean separated Asia from it? Was it just a good (educated) guess, or did the mapmakers have information that has not come down to us? You want the answer? Well you can listen to the interview and then go buy the book. All will be reveled!

You’ve probably heard of the Hudson River, and you may have even heard of Hudson Bay. But have you ever heard of Henry Hudson? Well you should, and now thanks to Peter Mancall‘s page-turning Fatal Journey: The Final Expedition of Henry Hudson (Basic Books, 2009) you can. And very pleasurably at that. Hudson was an explorer. He was looking for fame and fortune, both of which happened to be located in what Europeans called the “South Sea,” that is, the Pacific Ocean. For there were found the Spice Islands on which could be found (you guessed it) spices. These spices were incredibly valuable. A boatload of spices was worth a boatload of cash. Hudson knew it, and so did everyone else. The problem was that it was hard to get there, particularly from England. One had to sail around Africa, and that was no easy trick. So Hudson set about looking for a Northeast (above Russia) and Northwest (above Canada) passage. In point of fact the former exists, though only modern icebreakers (often nuclear powered) can get through it, and the latter doesn’t exist at all. Hudson didn’t know that. He had bad maps. So he tried, four times actually, to make it through. On the fourth voyage everything in the Far North went south, so to say. Cold, hunger, mutiny, murder. Peter tells the whole gripping tale, and very well. I’m hoping the book will be made into a movie. I’m thinking Russell Crowe (obviously) for Hudson.
