Soldier with a three barrel hand cannon (三眼銃, San yan chong) and the noblewoman, late period Ming dynasty (late 16th~early 17th century).

Some ranting : I love Ming dynasty clothing but it's so hard to get proper historical sources on the internet. The information about the original artwork (especially the title and period) often gets lost, so all I can see is just cropped images or modern reconstructions. Probably it's because I can't speak Chinese, but on the other hand Han, Tang, Qing, and even Song dynasty clothing were relatively easy to find.
