A 1763 copy of a purported 1418 map of the world shows the Americas and Australia and may prove that Chinese explorer Zheng He (a.k.a. Cheng Ho) circumnavigated the globe far before Columbus or Magellan. The map will be unveiled and on display in Beijing and Greenwich next week.

This is great stuff and makes us wonder where the chinese got their info from.Surely then the great explorers must have known about existing maps etc. and were much more aware of the newworld than we were led to believe from our school history classes.
Read 1421 The Year China Discovered the World by Gavin Menzies if you doubt and have your eyes ripped open. Cook knew where he was going he just didn’t have the accurate means of locating it on his first voyage
