First regional map of America to show California as an Island. Prior to this map, all maps with California shown as an Island were either World maps, Western Hemisphere, North America, Pacific Ocean or some substantially larger geographical region. The region illustrated was still largely unknown. First map to show 2nd Sanson Model of insular California (two bays shown in Northernmost portion of the island). Nomenclature is a combination of Blaeu and Sanson. New Indian tribes named along the Rio Grande. The peninsula above California is a curious and unexplained addition. A seminal map, which influenced California Cartography for the next 50 years. A cornerstone map for California collectors. Burden 327; Leighley 9; McLaughlin 16; Tooley p.116. The true first state, which rarely appears on the market.
Nicholas Sanson (1600-1667) is considered the father of French cartography in its golden age from the mid-seventeenth century to the mid-eighteenth. Over the course of his career he produced over 300 maps; they are known for their clean style and extensive research. Sanson was largely responsible for beginning the shift of cartographic production and excellence from Amsterdam to Paris in the later-seventeenth century.
Sanson was born in Abbeville in Picardy. He made his first map at age twenty, a wall map of ancient Gaul. Upon moving to Paris, he gained the attention of Cardinal Richelieu, who made an introduction of Sanson to King Louis XIII. This led to Sanson's tutoring of the king and the granting of the title ingenieur-geographe du roi.
His success can be chalked up to his geographic and research skills, but also to his partnership with Pierre Mariette. Early in his career, Sanson worked primarily with the publisher Melchior Tavernier. Mariette purchased Tavernier’s business in 1644. Sanson worked with Mariette until 1657, when the latter died. Mariette’s son, also Pierre, helped to publish the Cartes générales de toutes les parties du monde (1658), Sanson' atlas and the first French world atlas.
