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 slate surface of this dial on the South porch is flaking badly and is also marred by patches of lichen. We can hardly make out the date which Burge gives as 1764 and Mrs Crowley as 1794. The motto "Summum jus summa injuria" has been translated as "The rigour of the law is the rigour of oppression" or colloquially, "The more laws the worse the damage". There were originally two names at the bottom; D.Sandercock has survived but his fellow churchwarden was represented only by an initial H when Mrs Crowley drew the dial in 1961, and even that has gone now. Only two stubs of the iron gnomon remain.
