Fine map of the Northern Hemisphere, originally published by Gulliaume De L'Isle in 1714 and revised and corrected by Philippe Buache.

The map shows many of the later cartographic myths and anomallies of the second half of the 18th Century, most notably the Sea of the West and the curious depiction of what would ultimately become the Aleutian Islands, shown as a massive peninsula extending towards Kamtchatka and Japan.

The Northwest passage has not yet been discovered, Buache provides significant conjecture as to its possible location. Over the course of the next 15 years, the Northwest Coast of America would be completely re-drawn, beginning with the discoveries of Captain James Cook in the region.

Philippe Buache Biography

Philippe Buache (1700-1773) was one of the most famous French geographers of the eighteenth century. Buache was married to the daughter of the eminent Guillaume Delisle and worked with his father-in-law, carrying on the business after Guillaume died. Buache gained the title geographe du roi in 1729 and was elected to the Academie des Sciences in the same year. Buache was a pioneering theoretical geographer, especially as regards contour lines and watersheds. He is best known for his works such as Considérations géographiques et physiques sur les découvertes nouvelles dans la grande mer (Paris, 1754).
