Is there a picture of the first seimoscope?

Yes, there are historical photographs of the first seismoscope, which was invented by Chinese polymath Zhang Heng in 132 AD. The device, known as the "seismoscope" or "seismometer," was designed to detect earthquakes and featured a bronze vessel with eight dragon heads, each holding a ball that would drop into a frog's mouth when seismic activity occurred. While the original device no longer exists, illustrations and replicas are available in various historical texts and museums.
