This slate dial has some unusual features and it is surprising to find that Mrs Crowley declined to draw it, describing it as "complicated and uninteresting". It is set in an arched stone surround and it declines 14° East. It shows the hours VI to IV divided into halves and quarters. Outside the main chapter ring can be seen a series of zig-zag lines which are transversals and along them are dots which further subdivide the hours into periods of 5 and 1 minutes. Transversals are seldom found on vertical dials and not all that often anywhere else. The date, 1855, is incorporated in the decorative gnomon. The upper section of the dial plate is eroded or overgrown so that the beginning of the motto is unreadable: ’[Work while ye have] the light. The night cometh when no man can work’. We know the entire motto because, for some reason, Mrs Crowley made a note of it on her drawing of the dial at Halwell. At the top, a cross in a flaming sun occupies the central position, to the left is a globe with the equator, the tropics and arctic and antarctic circles, and to the right is the moon. The dial measures 610mmh x 460mmw.
