This attractive hand-colored map offers some new data, but, despite its title, does not cover the traditional New Mexico area. Tirion's information for the Pimeria region comes from Jesuit manuscript maps produced subsequent to Kino's day. The entire Gila River is now named correctly. What is known today as the Salt River is labeled "Riv. Azul". It is interesting to note that Tirion uses an old name for the Gulf of California- -"De Vermiljoen Zee." Tirion (d.1769) was a book publisher out of Amsterdam and published at least three atlases.
