Description
A pocket sundial in working order, designed for use in Europe. On the lid label is a list of the latitudes of major towns, allowing the string gnomon to be adjusted to the correct position (from 38 to 55°). The two inside labels are decorated with garlands. The compass is marked with eight points in German and the magnetic variation is marked at 18° west of north and is signed 'P.B.'.
Paul was the son of David Beringer (1756-1821), a master craftsman who specialised in scientific instruments such as these.
