A map from William Robertson’s popular History of America, one of the first scholarly histories written of the western hemisphere. The map was partly intended so that “the Motions of Cortez may be Traced.” The information in Mexico, including New Mexico up the Rio Grande, is quite good, but little is shown in California, and to the east of New Mexico is indicated a large empty land labeled “Great Space of Land unknown.” Along the Gulf coast the major rivers are indicated and in “Tecas” are noted Natchitoches, Cenis, and Presidio, near the latter of which is indicated “Here M. de la Sale settled in 1685. Also shown along the Mississippi is “Natches destroy’d.” An inset in the lower left shows the environs of Mexico City.
