Michelangelo had apprentices and assistants, many of which did a significant portion of the work. You could model him as the executive artist, directing the vision. Is this so different from prompting? Whose name is attached to all those works?

I will say Michelangelo was particularly controlling and distrusting of assistants, and uniquely did more work than other master artists of the time, but the point remains. The vision has always been the value.
