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.
Designed by Christopher Daniel and made by Martin Jennings, this vertical mean time noon mark made from black slate measures 2119mmh x 803mmw. It was installed on the Radcliffe Observatory in 1995 to commemorate the bicentenary of the observatory in 1994 as the inscription round the edge of the slate tells us. On the wall above the mark is a rod carrying a perforated disc through which a spot of light is cast on the appropriate position of the analemma at noon. The vertical line labelled XII and 1pm shows solar noon at Greenwich in GMT and BST and the line with a cross below it gives solar noon at Oxford.. Diagonal lines mark the equinoxes and solstices. The mark declines 23°50’ E. At the bottom is the inscription ’Meridies Media.
