These are a very good example of a typical Saxon Mass Dial and were removed from the wall close to the Lych Gate in 1936 where they had been placed and exposed for at least a century. Prior to that they had been put to other uses but it is not known exactly what. Originally these dials would have been fixed in the south wall of the previous church building and would have indicated approximately, by means of a shadow cast by a peg, the hour of Mass and other daylight services. High Mass in early times was 9am and a cross will be observed marking this hour on the more distinct of the two dials.
