Description Notes
Augsburg dial, by Johan Schreteger, German, late 18th Century or early 19th Century.
Brass, octagonal-based Augsburg dial with a compass and three hinged elements; an equinoctial ring, a latitude arm, and a pendulum. The compass features cardinal points marked in Latin (S, OR, M, OC), as well as the magnetic North-South axis indicated by an E-E line. The compass is covered by a sheet of glass. The main body of the dial is decorated with engravings, as is the frame for the pendulum. There are three feet on the base of the object, on which it stands. The base of the object is also engraved with the latitudes of some European cities; Augsburg, Paris, Krakow and Prague, as well as the name of the maker: Schreteger.

Description
Robert Stewart Whipple gave this brass sundial to his grandson for Christmas 1948. It was donated to the Museum in 2025, making it our most recent acquisition connected with our founder.
Portable equatorial sundials were a speciality of Augsburg, and Johann Schrettegger (c.1764-1843) came at the end of a long tradition. He was trained by his father-in-law, the famous instrument maker Andreas Vogler.
The compass enables the user to find North and the latitude dial can be adjusted to your current latitude, so that when the sun shines on the gnomon the shadow it casts indicates the correct time. Underneath are engraved the latitudes of Augsburg, Paris, Cracau (Krakow) and Leipzig. This makes it easier to determine your position.
