A castle clock is a clock whose face is mounted outside a castle or perhaps a church tower. They may be elaborate or simple.
Al-Jazari constructed an elaborate clock and described it in his Book of Knowledge of Ingenious Mechanical Devices in 1206. It was about 3.3 metres high (11 feet), and had multiple functions alongside timekeeping. It included a display of the zodiac and the solar and lunar paths, and a pointer in the shape of the crescent moon which travelled across the top of a gateway, moved by a hidden cart and causing automatic doors to open, each revealing a mannequin, every hour. It was possible to re-program the length of day and night daily in order to account for the changing lengths of day and night throughout the year, and it also featured five robotic musicians who automatically play music when moved by levers operated by a hidden camshaft attached to a water wheel. Other components of the castle clock included a main reservoir with a float, a float chamber and flow regulator, plate and valve trough, two pulleys, crescent disc displaying the zodiac, and two falcon automata dropping balls into vases.
Famous quotes containing the words castle and/or clock:
“If, in looking at the lives of princes, courtiers, men of rank and fashion, we must perforce depict them as idle, profligate, and criminal, we must make allowances for the rich men’s failings, and recollect that we, too, were very likely indolent and voluptuous, had we no motive for work, a mortal’s natural taste for pleasure, and the daily temptation of a large income. What could a great peer, with a great castle and park, and a great fortune, do but be splendid and idle?”
—William Makepeace Thackeray (1811–1863)
“The stars move still, time runs, the clock will strike,
The devil will come, and Faustus must be damned.
O I’ll leap up to my God: who pulls me down?
See, see, where Christ’s blood streams in the firmament.
One drop would save my soul, half a drop, ah my Christ.”
—Christopher Marlowe (1564–1593)
