Very rare map of California and the Southwestern US and parts of Mexico, form Jose de Acosta's De Natura Nova Orbis. The map is based upon Wytfliet's Atlas of the prior year, which was the earliest map devoted to Baja California and the Southwest. Metellus, whose real name was Jean Matal, was an accomplished French Cartographer, who died in 1597. The maps were most likely finished by Conrad Loew, a pseudonym for Matthias Quad. Some question has been raised as to whether Metellus' work predates the Wytfliet, given that Metellus died in 1597 and lived in Louvain prior to his death in Cologne. Burden surmises that Wytfliet's work was published first. The maps are largely similar, other than the ommission of a few place names in the Metellus. The Metellus is by far the rarer of two, this being the first example we have ever seen. A nice dark example, with text on German Text on the verso, as called for in Burden 120. An essential map for California collectors.
