OK. What specifically don't you understand? Leonardo being the most famous and still using craftspeople was my point.

“Craftspeople”? You mean his architectural work? He was, by all accounts I’m aware of, an incredibly hands-on artist. Having others help out is one thing. Having others execute is another. Having a workshop (as in, tools, bricks morter, etc.) is just par for the course.

Can you point out an artefact that he instructed someone to make and then labelled as his own artwork? Or indeed a piece still called a DaVinci that it's accepted he has no hands-on input to.

FWIW we're not taking about apprentices doing blocking-in, backgrounds, or minor characters.
