The question should not be, "Who was the most skilled artist of their times?" Or, of any times, but one of, "Does the piece of artwork skillfully render the message clearly?" It shouldn't be about a flourishing of skill so much as it should be about sufficiency of technique, that is, "Does the artwork I am looking at have what it takes to communicate effectively and sufficiently, on some levels of feeling, and thinking?"
Because, as we know of there are the rudimentary forms present in this world as we know it, and the lavishly produced at this time. It is a matter of tone to me.
