Topographic Map of De Centa Valley


This clear and beautifully executed late 18th century Spanish map of the vicinity of Oran in the extreme north of Argentina was intended to promote settlement in this region. The map was prepared at the behest of Ramón Garcia de Leon y Pizarro, Governor and Captain General of the Province of Salta, who founded Oran in August 1794, possibly as an outpost to strengthen Spanish territorial claims along the then Spanish-Portuguese frontier. The map shows the planned and partially settled community of Oran, other settlements, a sugar plantation, individual land holdings, rivers and streams, roads, administrative boundaries, locations of native ("Ynfieles") sites, and vegetation and relief. It includes a decorative cartouche with title and inscription, a keyed legend, and a lengthy note on the geographic and strategic advantages of the area, indicating that the map's primary purpose was to promote settlement. The map is dedicated to the "Rey Nuestro Señor Don Carlos IIII" (King Carlos IV).
