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 inscribed with the Coat of Arms of Nehemiah Griffith (1690 - 1738), for whom it must have been commissioned. It also has the latitude of Rhual, 53° 20", and is signed ’Culpeper, Londini’ (Edmund Culpeper, 1660 - 1737). There is a very finely engraved diagram of the solar system in the centre of the dial plate below the gnomon on the south side, and also the distances of the first seven planets from the sun (in millions of miles, as then understood), along with their zodiac symbols.
Beneath the gnomon on the north side is an Equation of Time table, for the 1st, 6th, 11th, 16th, 21st and 26th of each month. In the bottom row of the table is the motto ’Eheu fugaces labuntur’ (Alas the fleeting [years] glide on) from the Odes of Horace.
There is also a Perpetual Calendar, and stars in a regular pattern, and other astronomical symbols.
Hours are marked by aligned numerals IIII - XII - IIII - VIII, with a noon gap, and are divided to 30, 15 and 7.5 minutes inside the chapter ring, and to 2 minutes, numbered in Arabic numerals at the tens, in an outer ring. Half hours are marked with a triple arrow design,
