The astronomical clock is one of the greatest Chinese contributions to the field of astrology. Invented by Su Song, an engineer, mathematician, and astronomer in 1090, the astronomical clock is one of the most famous ventures in the measurement of time.
The clock itself is a complex mechanism with an escapement system, gearing, and transmission chains, a celestial globe, and an armillary sphere. This machine is one of the most precise pieces of clockwork ever invented. It was turned mainly by a slow-moving continuous wheel driven by rotating buckets fed by a tank kept at a constant level.
The astronomical clock revolutionized the field of astrology and mathematics and has allowed other scientists and mathematicians to expand the ideas of Su Song.
