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 mounted on the north range of Old Court just above ground floor window level, to the right of staircase D, and declines about 4° west of south. It was designed by Frank King and made by the Cardozo Kindersley workshops in Cambridge.
It has Babylonian and Italian hour-lines (showing hours since sunrise and since the previous sunset). The hours are read from the shadow of the brass nodus ball (this type of dial does not require a polar-directed gnomon).
Across the top section of the dial, above the winter solstice curve, is a rising sun with the inscription ’ΚΑΙΡΟΝ ΓΝΩΘΙ’ (Know the time). Across the lower part, below the summer solstice, is inscribed ’Collegio suo / lactarius Eboracensis / me dono dedit’ (To his college the Yorkshire dairyman gave me as a gift). Around the rim of the dial are inscribed ’Babylonian hours since sunrise’ and ’Italian hours since sunset’.
