This rare 1742 map of the Rio Grande Valley of New Mexico originally done in 1688 by Coronelli, cosmographer of the Republic of Venice and royal cartographer to Louis XIV, accentuated its importance as still the best and most exact large-scale map of the region. Although California is still depicted as an island, the map nevertheless shows the Spanish discoveries and pueblos along the upper Rio Grande.
