Sundial and Moondial.

Queens' College, Cambridge. In Old Court, above the passage to the Old Chapel, is a large wall dial with intricate and colourful markings yielding time, date, sign of Zodiac, elevation of the sun and so on. It was first constructed in 1642, and decorated in it's current style by 1733. A table underneath provides the moon's hour-angle for each day of the lunar cycle, enabling the dial to be used as a Moondial.
I have the instructions for reading it, but it seems quite complicated.
