Carte D'Amerique, dresée pour l'usage du Roy

Originally issued by Guillaume Delisle in 1722, this was one of the most popular maps of the Western Hemisphere in the 18th century and was printed in numerous editions. This is the important seventh state of the map, notable because it depicts the mythical "Sea of the West" north of California. An inset in the top left features Buache's elaborate Northwest Passage theories, including a conjectural Lac de Valasco. In Labrador is another hypothetical inland sea, Mer Nouvellement Decouverte. In South America, Brazil is separated from the Pays des Amazones. The map is decorated with a garland-draped title cartouche, "Avertissement" cartouche, and compass rose. Buache's imprint is in both the title cartouche, dated 1722, and at bottom right, with the nearly-illegible date of 1745. Tooley (America) #7 p. 14. McGuirk #111. Wagner (NW) #523.
