Portable Cube Sundial David Beringer Ca. 1780–1821 Beringer Is Best Known For Portable Wooden

Beringer is best known for his portable wooden sundials with scales printed on paper glued to the wood. These included cubic dials and diptych dials. Some of Beringer's sundials were collaborations made with Georg Paul Seyfried, who was also a compass master. Seyfried became a master in 1776, so Beringer-Seyfried dials probably date from 1777. Polyhedral sundials represent the culmination of knowledge in gnomonics and demonstrate the ability and scholarship of the gnomonist. As they have different faces, these are not lit at the same time, so that depending on the course of the sun in the sky, one or the other is lit depending on the time and can thus be seen or seen from different angles.
