Striking Clock - Counting The Hours

Counting The Hours

During the great wave of tower clock building in 14th century Europe, around the time of the invention of the mechanical clock itself, striking clocks were built that struck the bell multiple times, to count out the hours. The clock of the Beata Vergine (later San Gottardo) in Milan, built around 1330, was one of the earliest recorded that struck the hours. In 1335, Galvano Fiamma wrote:

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.

Some rare clocks use a form of striking known as "Roman Striking" invented by Joseph Knibb, in which a large bell or lower tone is sounded to represent "five", and a small bell or high tone is sounded to represent "one". For example, four o'clock would be sounded as a high tone followed by a low tone, whereas the hour of eleven o'clock would be sounded by two low tones followed by a high tone. The purpose is to conserve the power of the striking train. For example, "VII" would be a total of three strikes instead of seven, and "XII" would be four strikes instead of twelve. Clocks using this type of striking usually represent four o'clock on the dial with an "IV" rather than the more common "IIII", so that the Roman numerals correspond with the sequence of strikes on the high and low bells. One small table clock of this type sold from the George Daniels collection at Sotheby's on 6 November 2012 for £1,273,250.

Famous quotes containing the words counting the, counting and/or hours:

    If all power is in the people, if there is no higher law than their will, and if by counting their votes, their will may be ascertained—then the people may entrust all their power to anyone, and the power of the pretender and the usurper is then legitimate. It is not to be challenged since it came originally from the sovereign people.
    Walter Lippmann (1889–1974)

    What culture lacks is the taste for anonymous, innumerable germination. Culture is smitten with counting and measuring; it feels out of place and uncomfortable with the innumerable; its efforts tend, on the contrary, to limit the numbers in all domains; it tries to count on its fingers.
    Jean Dubuffet (1901–1985)

    Put in hours and hours of planning, figure everything down to the last detail, then what? Burglar alarms start going off all over the place for no sensible reason. A gun fires of its own accord and a man is shot. And a broken-down old house no good for anything but chasing kids has to trip over us. Blind accidents. What can you do against blind accidents?
    Ben Maddow (1909–1992)
