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 was delineated by Frank King and built by the Cardoso Kindersley Workshop. It celebrates the centenary of Staple Inn Actuarial Society. The design reveals an owl,symbolising the importance of wisdom, along with small staples of wool, after which Staple Inn takes its name. The owl stands on a ribbon inscribed ’E PERITIA RATIO’ (Reason from experience), the motto of the Institute and Faculty of Actuaries. The hour lines for 7am to 5pm radiate downwards from the image of the woolsack, and equinox and solstice declination lines are shown. Across the top is ’Staple Inn Actuarial Society’, and across the foot ’Centenary 2010’.
