BRIDOL is the British Sundial Society's Register of Fixed and Mass Dials, which gives detail and photographs of about 8000 fixed sundials and 3000 mass dials in the UK.
Some of these are in private gardens, but the majority are publicly available.
V - XII - IIII - VII, read from outside. Split noon. Divided to half and quarter hours. 16-point compass rose around the gnomon root, labelled to NE etc. Motto at N, read from the S ’Hodie, nunc!’ (Today, now!) - taken from the writings of the Spanish priest, Josemaria Escriva, founder of Opus Dei. Below that, the Lat and Long of the site, and to the S of the gnomon, a curved EOT graph. The hour lines are offset by about 11 minutes to allow for the longitude of the site thus enabling the dial to display Greenwich time rather than local time. The hour scale is rather misleadingly labelled ‘GMT’, although the dial actually displays Greenwich solar time and it is necessary to make a correction for the Equation of Time in order to produce Greenwich Mean Time.
