One of the best documented early expeditions in world discovery about Magellan's difficult and almost impossible voyage to circumnavigate the globe. Bergreen is an engaging author who mined many historic sources to give the reader an accurate view as possible about this difficult and trying voyage. Magellan had not only no maps to use, but also suffered from the political intrigues of his expedition captains. It is a look at the 15th Century whose people were not much different than those of our own time. This should be required reading for all historians and students of this period of European history.
