Exeter Cathedral
On the north wall of the north transept is a large, blue-faced astronomical clock, donated by Bishop Peter Courtenay (1478-87). The minute hand was added in 1759. A fleur-de-lys represents the sun cycles around a 24-hour dial, with noon at the top and midnight at the bottom. The moon's phases are shown and the day of the lunar month can be read from the inner ring. The gold ball in the centre represents the earth.
