Description:
Fascinating study in the comparative cartography of the West Coast of North America, from the Straits of Anian to Cabo San Lucas and the southern tip of Baja California. The work consists of extracts from two maps, both reportedly done by Visscher in the 1612 and 1641 respectively and with information derived from Mercator and Plancius. The larger map prominently shows the Strait of Anian, Anian Regnum, Quivira Regnum, the Sierra Nevada, Nova Albion, Tontonteac Regnum, Tolm Regnum and a coastal detail which includes over 30 coastal place names, including Mendocino, San Miguel (San Diego), Cape Fortuna, I. De Paxaros (Catalina?), and many mythical/ephemeral place names. The smaller map also shows the Straits of Anian, but depicts an open sea above, clearly portending a NW Passage in the Arctic Circle. The NW Coastline differs radically, and only Anian Regnum and Quivira Regnum are located, that later considerably south of the location on the larger map. The smaller map includes a similar number of coastal placenames, but includes several important ones not listed on the larger map, including C. Blanco (3 times), C. de San Francisco and los Farilones, but ommits any significant effort to depict bays.

Encyclopaedie Raisonee des Sciences des Artes: 
At the time of publication these maps of Encyclopedie were some of the most in-depth and accurate maps published of Asia, Canada, California and the NW region of America.
Diderot's maps were intended to further an understanding of the Western Coast of America, and NE Asia, during a time period immediately prior to Cook's voyage to the region - less than a decade later- where numerous theories abounded on the NW Coast of America. A nice dark impression of this essential map for American map collectors. (Ref: Tooley; M&B)
