Quadrant, Brunswick, 1608
Florence, Istituto e Museo di Storia della Scienza, inv. 2465, 1495

An extremely beautiful quadrant for performing mathematical, astronomical, astrological and military calculations. The sophistication of its decorative apparatus is matched by the extraordinary precision of the lines etched on it, thus giving results with only a narrow margin of error.
