Portable cube sundial David Beringer Ca. 1780–1821, 18th - 19th century - Beringer is best known for his portable wooden sundials with scales printed on paper glued to the wood. These included cubic spheres and diptych spheres. Some of Beringer's sundials were collaborations with Georg Paul Seyfried, who was also a master of the compass. Seyfried became a master in 1776, so the Beringer-Seyfried dials probably date from 1777. Polyhedral sundials represent the culmination of knowledge in gnomonics and demonstrate the skill and erudition of the gnomonist. As they have different faces, they do not light up at the same time, so that depending on the path of the sun in the sky, one or the other lights up depending on the time and thus it can be seen or seen from different angles. Good condition. 22X15X9 cm
