What animals adorned the bronze seismoscope created by Zhang Heng?
Answer
Dragons and toads
The seismoscope was constructed as a large bronze vessel featuring eight dragon heads, each facing a cardinal or intercardinal direction. Positioned directly beneath the mouth of each dragon was a bronze toad with an open mouth. The mechanism was ingenious in its design, utilizing gravity and movement to release a ball from a dragon into a toad, thereby signaling the specific direction of a seismic event.
