Amsterdam: Cornelis Claesz, 1633.
Map. Hand colored engraving. 18" x 22 1/2".
Early 17th century map of northern Spain showing the Basque region. Bilbao is prominent near the coast. Rivers, mountain ranges, and cities are denoted, and beautiful hand coloring outlines different provinces within the region. Decorative cartouche in the lower right. Foxing throughout. Mercator (1512-1594) was an accomplished mathematician, cartographer, globe maker and engraver but is best known for the Mercator Projection. Incorporating the newly accepted fact that the world is round, Mercator was able to render longitude lines consistently straight on a chart. Although this requires some distortion, it was of great use for navigators, and is historically important, as it is still the most commonly used projection today. French text on verso.
