A rare and extremely unusual map projected from the North Pole as if it were the table of a sundial. The landmasses are drawn to scale in proportion to their distance from the pole. The result is a very distorted, though mathematically correct, projection. Ten horological diagrams surround the central map and all are enclosed in a decorative border. The plate was designed for Ritter's first edition of the Speculum Solis in 1607. It is a synopsis of all the plates that appear in his later editions.
