One of the more remarkable combinations of fact and fiction in a map of the Pacific Northwest. Its source was an account published in 1708 of what purported to be a newly discovered account of a voyage in 1640 by the Spanish Admiral, Bartholomew de Fonte. Thereafter, the account was changed and elaborated upon, most notably by this series of maps which appeared in Diderot's Encyclopedia. In its concept it promoted the hopes of a Northwest Passage and depicts the existence of "Mer de l'Ouest" or the Sea of the West. Ref: Pedley #454, Hayes #34. Faint ink offsetting, which can easily be erased.
