Striking clock
Counting the hours
There is there a wonderful clock, because there is a very large clapper which strikes a bell 24 times according to the 24 hours of the day and night, and thus at the first hour of the night gives one sound, at the second two strokes, and so distinguishes one hour from another, which is of greatest use to men of every degree. The astronomical clock designed by Richard of Wallingford in 1327 and built around 1354, also struck 24 hours.
