Medicine and science in ancient Rome and China

Various illness ailed ancient peoples, although plagues or large-scale epidemics spared the Chinese and western European world until the second century.  To treat deceases and wounds, both world resorted to surgery, although the Chinese tended to emphasize more on herbs and less invasive methods. Without anesthesia, both peoples upheld the ideal of enduring surgery with stolid calm.

The creativity of the Roman Empire and Han China declined compared to that of pre-imperial times, but was still formidable. Hero of Alexandria was a prolific inventor, among whose works was a steam engine. ZhangHeng of the Latter Han invented a seismograph in 132.
9. Hero's steam engine.
A schema of Hero’s steam engine. A rotatable hollow ball is suspended by two pipes, which let in the steam generated by boiling water in an enclosed container. The high-pressure steam escaping from opposite outlets set the ball rotating, the work of which can be harnessed.
10. Ancient Chinese seismograph.
A model for Zhang Heng’s seismograph. The bronze jar has eight dragons facing eight directions, each holding a ball in its mouth. Inside the jar is a pendulum constrained to swing in eight channels. Shock waves from of a distant earthquake set the pendulum swinging along their direction of propagation,  which causes the dragon facing the epicenter to open its mouth and drop the ball into the mouth of the frog below.
