This horizontal dial consists of a flat, cylindrical block of wood with ivory insets on all sides and an applied silver ring on its UPPER SURFACE.
The hours are engraved on the silver ring from IIII to XII to VIII, with the XII in smaller figures than the others. Above the numerals are four paired piercings, probably for fixing the instrument to other parts of the miner’s survey set of which it once formed a part.
In the central part of the block, also on the upper surface, are two COMPASSES with the cardinal points abbreviated 'SE', 'OR', 'ME', 'OC' in alternating red and black letters. The rest of the wood block, including the rim, is inset with ivory floral scrolls.
In the ivory scrollwork on the UNDERSIDE of the wood block are inscribed the signature of the maker and date and place of production of the instrument. At the centre of this side are a circular well and a square perforation for fixing this part to the rest of the set.

- Curator's comments
- Designs on the front of this instrument are similar to those on the back of a wood and ivory sundial at the Greenwich Maritime Museum, reg. no. AST0484; however that (unsigned) instrument has no metal hour ring and is about half the size of this one. The Greenwich instrument has however been attributed to Hans Graf because of its similarity to this one. See H. Higton, Sundials at Greenwich, Oxford 2002, no. 12, p. 65.
