Amsterdam: Jodocus Hondius, 1616. Petrus Kaerius. unbound. Map. Engraving with hand coloring. Image measures 14.75" x 20.25" very good.
Map of Iberian Peninsula, beautifully decorated with ships and sea monsters. French text on back. Scattered staining and crease right of centerfold, that has led to a few small holes from original coloring. From the "Gerardi Mercatoris Atlas sive Cosmographicae" (Mercator-Hondius Atlas). Plate was originally made by Mercator and later added to by Hondius. 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.
