Description

A 14th century illustration of a Chinese cannon, or eruptor, which fired proto-shells as cast iron bombs.

This specific cannon was called the "flying-cloud thunderclap eruptor" (feiyun pilipao). The smaller shells did not have an exact fit with the bore, but a kind of wad or cradle for the is shown.
