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.
A complex multi-faceted dial, this is full of interest. It lies in the open on a lawn at the north-west corner of the Downing site. Of the 17 dial faces, 16 bear Arabic numbers.
It was given to the Department of Archaeology by Professor Sir William Ridgeway and his wife in 1913, as the inscription - WILELMUS ET LUCIA RIDGEWAY POSUERUNT A.S.MCMXIII - makes clear. (A.S. = Anno Salvationis)
The topmost gnomon is pierced with
the design of a seated camel. The maintenance of this dial is a first charge on a University Fund.
