This interesting map is usually referred to as "the first scientific map of the Amazon". It shows the expedition in 1743-44 of Charles-Marie La Condamine, a French scientist and explorer. His was the first scientific account of the Amazon, including notes on how the native used curare for poison, and introduced rubber trees to Europe.
