    • Diptych dial (Inv. 3173)

Dial in the shape of a small box. A compass for orienting the instrument is fitted into the base (the magnetic needle is missing). The gnomon consists of a string that stretches into alignment with the celestial axis when the box lid is opened. The insides of the lids are inscribed with two horary quadrants, the date 1767, and the initials LM, from which the maker cannot be identified.
