St Mary’s Church, Grundisburgh

This break-arch shaped dial on the south wall of the church tower, below a clock, declines about 23° to the east. The tower dates from 1731-32, but it is not known whether the dial is contemporary. A motto within the arch reads: "LIFE PAS’S LIKE / A SHADOW". Scales around the gnomon root show the time at two other places, but they are not named. The outer scale, with Roman numerals for 8am to 7pm, using XII and IIII, shows the time at about 37° E, so may be intended to show Damascus time. The inner scale, with Arabic numerals 1 to 12, shows the time at about longitude 60° W, possibly for Barbados. The main dial shows 5am to 4pm in upright Roman numerals using XII and IIII, divided to quarter hours. The gnomon rod has an ’S’ shaped supporter and carries a ball nodus, which is associated with nine declination lines numbered 8, 9, J0,J1, J2, J3, J4, J5, J6 (8 to 16 for the hours of daylight). The nine vertical lines crossing these are for azimuth, the nodus shadow showing the direction of the sun. They are also unlabelled, but will indicate bearings of SEbE, SE, SEbS, SSE, SbE, S, SbW, SSW and SWbS. (A report in September 1983 found the dial completely bare, presumably prior to a restoration.)
