BERGAUER, INNSBRUCK A German late seventeenth-century silver and firegilt brass equatorial sundial with mechanical minute indication, signed Io Mi Bergauer in Insprug (Johann Michael Bergauer Innsbruck), c. 1680. The instrument consists of two parts which are hinged. The lower part is richly engraved and contains a compass and a plumb line for positioning it. On the back a number of European cities are engraved with their corresponding latitudes so that the upper part can be adjusted by a turnable spiral on the lower side according to the latitude where it is used. The upper part has a Roman chapter ring I-XII twice, with half hour and quarter hour divisions. The gnomon is placed on a manual silvered minute disc with gilt brass hand. This construction makes it possible to read the time on the basis of the shadow cast by the gnomon in minutes. Diameter: 7.5 cm. Literature: J. Abeler, Meister der Uhrmacherkunst, 2010, p. 59
