Who made the oldest astronomical clock in the world?

The oldest astronomical clock in the world is a water transport instrument made in China, which is a large astronomical instrument. The photographic platform of water transport instrument was designed by astronomers Su Song and Han Gonglian, and made in Song Dynasty.

It is a multifunctional comprehensive observation instrument. Not only can we observe and demonstrate the celestial phenomena, but we can also calculate the time and tell the time. In this respect, it is actually a small observatory.

Structurally, the extended data is divided into three layers: the upper layer is equipped with an armillary sphere for observing the positions of various celestial bodies. On it, you will see a circle surrounded by nine movable roof panels, just like the circular roof of the modern observatory, all for the convenience of observation. This wonderful structure can be called the originator of the modern observatory. In the middle layer, the elephant is a sphere that keeps running, and it takes a day and a night to turn around.

On its sphere, the star positions of various celestial bodies are marked. In the process of its rotation, it not only truly shows the changes of astronomical phenomena, but also always observes celestial bodies in the same sky area. It is also the ancestor of the rotating clock, the tracking device of the modern observatory.
