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.
The dial is In a window of the cloisters. The main panel is quite badly cracked and has a leaded repair. There is a three sided orange chapter ring with black lettering, all on white ground, showing 8am to 6pm [delin 7am to 6pm] in half and quarter hours. A cross patty is used for Noon and IIII for 4pm. The painting is fine enough to allow the species of butterfly and fly to be identified. They all appear to be painted on the one side of the glass and form a rebus on ’time flies’. The lower panel has the maker as "JR fecit 1733". The dial is known to have been brought to Arbury in 1785 but there is no record of whence it came. There is no gnomon and it is unclear whether the dial is in a properly facing window, but it is believed not.
