The weight-driven mechanical clock controlled by the action of a verge and foliot was a synthesis of earlier ideas from European and Islamic science. Mechanical clocks were a major breakthrough, one notably designed and built by Henry de Vick in c. 1360, which established basic clock
The word clock (via Medieval Latin clocca from Old Irish clocc, both meaning 'bell'), which gradually supersedes "horologe", suggests that it was the sound of bells that also characterized the prototype mechanical clocks that appeared during the 13th century in Europe.
The first all-mechanical clocks which emerged in Europe in the late 13th century kept time with a verge escapement and foliot (also known as crown and balance wheels). In the second half of the 14th century, over 500 striking turret clocks were installed in public buildings all over Europe.
Salisbury Cathedral clock, restored.

The Astrarium of Giovanni Dondi dall'Orologio was a complex astronomical clock built between 1348 and 1364 in Padova, Italy, by the doctor and clock-maker Giovanni Dondi dall'Orologio. The Astrarium had seven faces and 107 moving parts; it showed the positions of the sun, the moon and the five planets then known, as well as religious feast days.
The escapement is just below it. From his 1364 clock treatise, Il Tractatus Astrarii. The verge escapement dates from 13th-century Europe, where its invention led to the development of the first all-mechanical clocks. [3] [9] [10] Starting in the 13th century, large tower clocks were built
The Backhaus Clock, also known as the Forchtenberg Tower Clock, is a historical mechanical tower clock located in Forchtenberg, Baden-Württemberg, Germany. It is notable for the year 1463 engraved on its frame in Gothic script , which marks it as the oldest dated tower clock still in operation in the world. [ 1 ]
