I won't bother getting into trying to demonstrate Medieval art doesn't "suck", it's not worth dignifying. But you should be aware you might be placing too much emphasis on painting and drawing specifically as opposed to other art forms.
Isn't the actual topic of this thread specific to painting? On sculptures, but the skillset is painting; you can't paint a marble bust with a chisel.
Fine, good point. Medieval paintings and drawings suck, but the pottery may have been incredible.
Yeah, why sacrifice dignity by providing a counterexample? Dignity is important.
