Seminal map of the Northern Hemisphere from Phillipe Buache's Considerations geographiques et physiques sur les nouvelles decouvertes au nord de la grande mer…, one of the most important works on the NW Coast of America of the 18th Century. Buache studied under the elder De L'Isle in Paris. This work, which was intended to illustrate the Russian discoveries in the Northwest, the Northwest Passage and other contemporary French cartographic conclusions regarding the region, was one of the prime catalysts for the mythical bay of the west. This map illustrates both the Bay of the West, a conjectural route from the Atlantic to the Pacific and the prospect of a River route, using portages. A essential map for collectors of the NW Coast of America.
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).
