First Mechanical Clock

Who invented the Clock,

Let's learn it

Mechanical Clock

The clock is one of the oldest human inventions, meeting the need to consistently measure  intervals of time. Water clocks, also known as clepsydrae, along with the sundials, are  possibly the oldest time-measuring instruments. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed  in Babylon and in Egypt around the 16th century BC. Other regions of the world, including  India and China, also have early evidence of water clocks, but the earliest dates are less  certain. Some authors, however, write about water clocks appearing as early as 4000 BC  in these regions of the world. Islamic civilization is credited with further advancing the accuracy of clocks with elaborate  engineering. In 797 (or possibly 801), the Abbasid caliph of Baghdad, Harun al-Rashid, presented  Charlemagne with an Asian Elephant named Abul-Abbas together with a "particularly  elaborate example" of a water clock. In the 13th century, Al-Jazari, an engineer who worked for Artuqid king of Diyar-Bakr,  Nasir al-Din, made numerous clocks of all shapes and sizes. His book "The Book of  Knowledge of Ingenious Mechanical Devices" described 50 mechanical devices in 6  categories, including water clocks. The most reputed clocks included the Elephant, Scribe  and Castle clocks, all of which have been successfully reconstructed. As well as telling the  time, these grand clocks were symbols of status, grandeur and wealth of the Urtuq State. Some of the most elaborate water clocks were designed by Muslim engineers. In particular , the elephant clock by Al-Jazari in 1206 are credited for going "well beyond anything" that  had preceded them. This clock incoporated the first robotics with moving, time-telling figures. The knowledge of weight-driven mechanical clocks produced by Muslim  engineers in Spain was transmitted to other parts of Europe through Latin translations  of Arabic and Spanish texts on Muslim .
