DE L'ISLE, G. / BUACHE, Ph.
Mappemonde à l'usage du Roy by Guillaume Delisle... Paris, 1755. Black and white. Important tear at the top and bottom of the central fold. 440 x 675 mm.
Curious late issue of De L'Isle's double hemisphere world map. This map is most notable for its depiction of "Mer de L'Ouest" or Sea of the West. A great sea, easily the size of the Mediterranean, to flow from the then-known Strait of Juan de Fuca. He also shows an opening to the ocean from this great sea at roughly in North California or Oregon and Quivira somewhere in Idaho. With the address of Ph. Buache, dated 1755. The map carries dates in its lower title cartouche up to 1754.
