A map of the discoveries made by Captn. Willm. Dampier in the Roebuck in 1699.

This map is of the islands of Timor, New Britain and New Guinea. It appeared in the first volume of John Harris' 'Navigantium atque Itinerantium Bibliotheca. Or, a Complete Collection of Voyages and Travels'.
The works was a collection of such travels as was popular at the time, this being one of the finest. It was first published in 1705 and then greatly expanded for this edition published in two volumes 1744-48 with many maps and plates by Emanuel Bowen.

A mixture of fresh, detailed cartography and revealing commentary. Dampier’s discovery of a strait separating New Guinea from the island he named New Britain has colonial significance, according to the note on the map: “Since it lessens the Difficulties of settling a Colony in this part of the World that might probably be attended with great Advantages, as well with respect to ye profits drawn from the Plantations as from the Commerce of the neighboring countries.” New Guinea, however, is the “least known to Europe of any of the Eastern Countries.”
As a result, Western imagination had been running wild: it is stated that most of the inhabitants are “Blacks, but there is a Nation of Whites seated in one part of it whom some have suspected to be a Remnant of ye Ten Tribes of Israel, who were carried into Captivity by the Assyrians.”
Practically speaking, it is difficult to “say Positively what are the Products of New Guinea because no Europeans have penetrated beyond its coasts.” This latter statement still rings true, for, after 250 years, despite repeated European attempts at domination (Dutch, German, English), the large island country remains remote, recalcitrant, and reclusive.
Probably the most telling discovery took place on August 4, 1938, when American zoologist Richard Archbold came upon the Grand Valley of the Baliem River, where fifty thousand yet-undiscovered Stone Age farmers were living in orderly villages. Known as the Dani, the people were the last large society to make first contact with the rest of the world.
