alt Hacker News> The end result would surely look better, but how would we be assured it resembled historical reality?
You can be fairly sure that no reproduction would literally resemble the reality, _including the existing reconconstructions_, but you can certainly produce a range of possible reconstructions which would have produced the same evidentiary record, and which would be at least inspired by what we know about contemporary taste that we can derive from surviving paintings and the textual record.
How do you prevent introducing a bias that then becomes what we "know" about how statues were painted? By introducing modern aesthetic sensibilities and present them as plausible, we then reinforce that this is how statues were painted back then, and we don't know.
I think the article is mostly begging the question, and is not particularly rigorous. At most it's appealing to some sort of common sense, and we know how tempting but unreliable common sense can be in science and history.
To me TFA reads mostly as "this reconstruction looks bad, I refuse to believe ancient Romans painted statues like this, therefore it must be an incorrect reconstruction."
