This was also one of the first spring-powered mechanical clocks in general, developed around the same time as Peter Henlein in 1556. Replica of an early 17th-century foliot-and-verge clock, 2. One high official, Su Song (1020-1101), is famous for having designed and constructed a mechanical clock tower (almost 40 feet high) by adding a chain-driven mechanism to the existing water-powered clock. ↩. According to historical research, the world’s first clock was invented by Yi Xing, a Buddhist monk and mathematician of the Tang Dynasty (618－907). It was an astronomical clock and he called it the "Water Driven Spherical Birds-Eye-View Map of The Heavens". The spring-powered clock was invented in about 1510 by Peter Henlein of Nuremberg, Germany, however the spring-powered clock did have its problems, that of slowing down when the mainspring unwound. Called Shadow Clocks, they were able to divide the day into 12-hour periods and used some of their enormous obelisks to track the movement of the sun. It also had a … Galileo . Astronomical Clocks.

The astronomical clock, which he built himself for his observations, was set up in the observatory. The first computer may have been invented sometime between 10 and 70 bc by hero of alexandria.
