Main text

This dial is distinguished by its size: it is probably one of the smallest surviving diptych dials, and is certainly the smallest in the collection of the Museum of the History of Science in Oxford.

It is made in the form of a book with brass bun feet, and consists of a compass and of a pin gnomon dial marking Italian hours. The maker's mark is punched on the outer side of the lower leaf but has not been identified.

Detailed text

The outer part of the upper leaf has an imitation of blind-tooling and five brass feet.

The inner part of the upper leaf has a decoration in the form of a twelve-leaf flower inscribed in a circle.

The inner part of the lower leaf has a compass (glass, needle and ring missing) and a pin gnomon dial (pin missing) for Italian hours numbered from 10 to 23. A star motif is in two sizes.

The outer part of the lower leaf has four brass feet, the same decoration as the outer side of the upper leaf and the maker's mark (similar to a bunch of grapes).

See P. Gouk, The Ivory Sundials of Nuremberg 1500-1700 (Cambridge, 1988).
