Chinese Cartography

Last Monday, I linked to an article about a map suggesting the Chinese had discovered the Americas before Columbus. You can read more about it at this article in the Economist.

The detail on the copy of the map is remarkable. The outlines of Africa, Europe and the Americas are instantly recognisable. It shows the Nile with two sources. The north-west passage appears to be free of ice. But the inaccuracies, also, are glaring. California is shown as an island; the British Isles do not appear at all. The distance from the Red Sea to the Mediterranean is ten times greater than it ought to be. Australia is in the wrong place (though cartographers no longer doubt that Australia and New Zealand were discovered by Chinese seamen centuries before Captain Cook arrived on the scene).
