At night, a lamp would be lit to indicate the hour by shining through a turning disc. Originally built in the famous Umayyad mosque in Damacus more than 800 years ago, this clock was re-constructed by Ridhwan al-Sa’ati. This impressive mechanical clock displayed the time numerically, and included two falcons that would automatically throw a copper ball into a vase to mark the passing of an hour. The observer would hear a cymbal-like sound, and both falcons would lean back to their original position and close their wings…ĭome of the clocks in the courtyard of the of Umayyad Mosque in Damascus. Soon after this happens, the two falcons would tilt forward and spread their wings, and a ball would drop out of their beaks and into the vase. This occured as each solar hour of sunlight has passed. When between two doors, the upper door would open to reveal a figure of a man, while the lower door flipped round to reveal a different colour. The crescent Moon would travel steadily from left to right on the frieze. During daylight hours, an observer would have seen the Sun’s disc on the eastern horizon about to rise, the Moon would not be seen at all and six zodiac signs would be visible, while the first point of the constellation Libra was about to set.

The castle water clock is one of the grandest clocks mentioned in Al-Jazari’s book. The first machine described by Al-Jazari in his famous treatise of mechanics Al-Jami‘ bayn al-‘ilm wa ‘l-‘amal al-nafi‘ fi sina‘at al-hiyal (‘A Compendium on the Theory and Useful Practice of the Mechanical Arts’) is a monumental water clock known as the Castle Clock. Manuscript view of the castle clock (Left) and computer assisted reconstruction (Right) © 1001 Inventions Scholars, inventors and craftsmen made innovative automata, carried out detailed mathematical analysis, constructed intricate clocks and attempted to master automatic control as they created and expanded upon inventions to mark and measure time. These sophisticated devices defied the Middle Ages.Ĭlocks and timekeeping were one of the most significant developments of Muslim civilisation. The design of digital clock using verilog hdl on fpga board 1.0 introduction digital clock means clock is using ciphers to display time digitally which is completely different from analog clock, where the.1001 Inventions reveals 7 marvellous mechanical and water-powered clocks from early Muslim Civilisation. Identify your device by actively scanning it for specific characteristics (fingerprinting).
