This is an instrument for drawing sundials. A contemporary manuscript, possibly written by the maker John Rowley, describes its use.

The three bands represent the meridian, the equinoctial and the horizon, while the thin plate, which tilts and rotates within the horizon band, represents the plane of inclination of the dial to be drawn. Using a candle and a line, shadows can be cast on to the plate for successive positions of the sun.
