Franz Ritter was a German mathematician and astronomer whose works are extremely rare. This beautiful engraving is a horological diagram remarkable for the elaborately engraved decorative border. At top is a large strapwork cartouche and at bottom is a 32-point wind rose. A very rare and unusual cartographic curiosity.
Margins expertly extended to better accommodate framing.
