I was recently on a /r/badhistory and there was a post about depictions of non-Europeans in European Medieval artwork. I was wondering if there are any good examples of the reverse, preferably before any obvious exchange between cultures (e.i. colonization/industrial revolution). The earlier the better. Also I would be very interested to see any artwork illustrating non-natives persons (like a Chinese merchant in Iran or something). Early contact between distant cultures really fascinates me, especially the idea of large trade networks and/or diplomatic missions that brought a variety of otherwise isolated cultures in contact.
