The earlier guns (those using saltpetre, not just fire-lances) from the Yuan Dynasty (1279 - 1368) were made of bronze, though I think later guns (Ming, 1368 - 1644, and onward) were made of cast iron. Can anyone verify that?
That is an important point. European specialists assume that any gun of the form that I attached must be European if it is iron. I am not so sure. Fact is that the form of Chinese/eastern guns that I have seen is not so very different from european guns of the period prior to 1400.
There is a well known engraving from a Jesuit that I cannot put my hand on at the moment but it shows types very, very similar to what I have posted.
A possible interpretation is that there was a more or less active trade between China and Europe that accounts for the presence of similar objects east and west.
The problem that this illustrates is that often we find that researchers are a bit too isolated in their thinking.
