A Renaissance workshop was not a democracy, and the evidence is still visible if you know where to look. The master handled faces, hands, and the principal figures' flesh. Everything else fell to assistants according to a strict internal hierarchy — not written into the contract with the patron, but understood within the bottega as clearly as a wage scale.
Drapery came first among the delegated tasks, and even here there were gradations. A journeyman of standing might paint the complex folds of a foreground figure, where the fall of cloth was itself a demonstration of skill. Architectural backgrounds — pilasters, barrel vaults, the receding tiles of a tiled floor — went to whoever understood perspective well enough to execute it cleanly, but it was still considered subordinate work. Sky and landscape, distant hills, generic foliage: these were the territory of the apprentice who had graduated past grinding pigment but not yet past supervision.
The clause in a contract specifying that the master would paint di sua propria mano — by his own hand — was protection for the patron, not a description of how a painting was made. It defined a minimum: the faces and principal figures were to be his, and the patron had paid for exactly that distinction. The assistant's contribution went unmentioned not because it was invisible but because it was expected and unremarkable.
What made this legible to contemporaries was familiarity with workshop practice itself. A patron who commissioned Ghirlandaio or Perugino knew he was commissioning an operation, and the contract's propria mano clause was a guarantee that the premium parts of that operation were not subcontracted. The rest was efficiently divided by rank.
Technical examination has since confirmed what the contracts implied: underdrawing in one hand, paint layers in several. Infrared reflectography routinely shows a single controlling intelligence in the design — and then a range of execution quality in what was built on top of it, the faces sharper, the distance softer, the sky painted faster than everything else.

Rank was not just social. It was spatial, and it is still in the picture.
