Diptych dial, leaves Ib and IIa
Diptych dial. Boxwood dial consisting of two leaves that fold together when not in use. On leaf Ia is a lunar volvelle, marked by Chinese characters. Six further Chinese characters in red paint read: 'Moon plate' and 'Combined Sun and Moon dials'. The volvelle is used with a brass screw pin, which is stored in a hole in the upper leaf. Leaf Ib features a vertical dial, within which four Chinese characters read: 'The tiny shadow [i.e. time] is precious'. Leaf IIa displays the horizontal dial. In the centre of the dial is a grey metal compass with the cardinal points marked in black around it (red for South). Down the sides of the dial are 13 holes for setting the angle of the lunar dial. There is a broken red string gnomon that was originally attached between the two leaves.
