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.
This is said to be the earliest green slate dial in Devon. It is a break-arch dial with the date 1710 running round the top of the arch. It has been suggested that it might have been made by Jno Berry but the early date and lack of signature makes this very unlikely. There is a sun-face surrounding the root of the gnomon and in a shield below that are the names of the churchwardens Joseph Palmer and William Karslake who style themselves ’Gents’. It has the hours VI - VI subdivided into halves, quarters and periods of 7 1/2 minutes. The half hour markers each have a fleur-de-lys decoration and noon is indicated by a decorative cipher. The upper corners appear blank: if there ever were any cherubs there, they have flown. The dial is 380pmm square.
