Polyhedral Dial
Attributed to Girolamo della Volpaia
16th century; Florence
Wood; 121 mm in height

A cube symmetrically cut to give four dial surfaces has on the top a scaphe dial for unnumbered Italian hours and a plain north face. The front two faces of the instrument carry dials declining at 45? for Italian hours for XI to XVIII and XVII to XXIIII for 42? latitude (Rome). Below the surface of these two dials the cube is undercut in conical form and marked 'G LXII'. Some traces of rubrication remain in the hour lines and inscriptions. Below the curved surface is a small compass set into the horizontal base.
