Talk:Representation of slavery in European art

Isn't this article confusing representations of slavery in European art with representation of blacks in European art (as if 1) blacks were only slaves in European history, and 2) all slaves in European history were black)? There should be a picture in the article of the Roman slaves of white race in triumph arches (since they are mentioned in the text), and there's really no reason for Thomas-Alexandre Dumas to appear (he was a slave earlier in his life, but he was portrayed when a freeman, and his portrait isn't a portrait of slavery), if we followed this reasoning lots of portraits of former slaves which don't portray slavery themselves would end up mentioned. Other than the article needing some paintings of non-black slavery (imagined or real), some images of Roman slaves of several ethnicities and the removal of the portrait of Dumas (it makes sense to mention it but more in a "Some people who used to be slaved were portrayed, not as slaves but in later situations as freed men, like Thomas-Alexandre Dumas who was portrayed as a napoleonic general." way), the article is actually quite good.
