Stand in front of a large Rubens in any major museum and you are looking at a collaboration. The master painted the faces, the hands, the final glazes that make the flesh seem lit from within. Much of the drapery, the architecture, the foliage and the sky came from assistants working in a well-organised Antwerp studio, some of whom, like the young Van Dyck, were considerable painters in their own right. Rubens priced his work accordingly, charging more for canvases with more of his own labour in them, which tells you the arrangement was neither secret nor scandalous.
This is the ordinary condition of art history rather than an embarrassing footnote to it, and it is worth remembering now that a similar anxiety has arrived in advertising: if software generated the performance, whose work is it?
Four Centuries of Delegated Execution
The workshop model was standard practice for most of European painting. Verrocchio’s shop trained Leonardo; the tradition held that the student’s angel outshone the master’s work in a shared painting, and the story was told with pride rather than as an accusation. Raphael ran an operation of dozens, and the later rooms of the Vatican apartments were executed largely by Giulio Romano and the rest of the shop working to his designs. Cathedral sculpture, altarpieces and tapestry cycles were all produced by teams working from a designer’s cartoon.
Modernity did not end the practice, it made it explicit. Warhol named his studio the Factory and had assistants pull the silkscreens; the mechanical distance was the point, not a compromise of it. Sol LeWitt sold wall drawings as sets of written instructions to be executed by others, a practice galleries still follow after his death. Jeff Koons runs a production operation of assistants and fabricators. Ai Weiwei’s ceramic works were made by craftsmen in Jingdezhen. In each case the artist’s authorship is undisputed by the market, the museums and the scholarship.
What art history worked out, slowly and with a great deal of argument, is that authorship lives in the conception and the final judgment, not in the hand that applied the pigment. Which hand held the brush is a question of process. Whose decisions the work embodies is the question of authorship, and they are not the same question.
It is worth noticing what the workshop bought its master, because the motive was never mere laziness. Delegation bought scale, which meant a Rubens could accept commissions from three courts at once, and it bought speed, which meant an altarpiece could be delivered before the patron’s enthusiasm cooled. It also bought range: a specialist in animals or still life produced better foliage than the master would have, so certain paintings improved by not being made alone. Those are the same three reasons a marketing team delegates production today, which suggests the impulse is structural rather than modern.
The Line That Actually Matters
None of this means the workshop had no ethics. It had a very specific one, and it was about representation rather than labour.
A studio painting sold as a studio painting was legitimate. A workshop canvas sold as an autograph work by the master was fraud, and the trade built machinery to police exactly that line long before anyone called it ethics. Renaissance commission contracts routinely specified which passages the master would execute personally, sometimes down to naming the figures, because patrons paying for a name wanted it written down what the name was actually going to touch. The offence was never that assistants painted the sky. The offence was misleading a buyer about the nature of what they were acquiring.
That distinction transfers cleanly to the current argument about synthetic media, and it is more useful than the reflex of asking whether AI involvement is inherently dishonest.
Where Advertising Sits in This Lineage
Brands now produce short vertical video at volumes no in-house team can film, and a category of tools has appeared to execute it. Software described as ai ugc generation reads a product page, drafts scripts and renders a presenter delivering them, which places it precisely where the workshop assistant always stood: performing the execution while the client supplies the concept, the constraints and the final approval.
UGCfy AI works in that shape, turning a product link into hook and script variants a marketer chooses among before anything is rendered. The interesting question is not whether this is legitimate, because delegated execution has been legitimate since the Renaissance. The interesting question is the workshop’s question: is the audience being misled about what they are looking at?
Applied to advertising the line falls in a recognisable place. A synthetic presenter explaining a product is a spokesperson, which advertising has used openly for a century. A synthetic presenter framed as a spontaneous customer testimonial is closer to selling a studio canvas as an autograph work, and the platforms have started codifying this with disclosure settings for AI-generated content. Use them, and the analogy holds honestly: the labour can be delegated, the representation cannot be falsified.
What the Master Kept
There is a practical lesson buried in the workshop model that survives the change of medium.
Rubens did not delegate the faces. LeWitt’s instructions were unusually precise about what mattered and deliberately permissive about the rest. Warhol chose the images. Across four centuries of outsourced hands, the constant is that the artist retained the decisions that carried meaning and released the ones that carried only labour, and the discipline was knowing which was which.
The same sorting applies to anyone using generation tools commercially. The message, the claim, the audience, the judgment about which version is true to the product: these are the faces, and delegating them produces work with nobody home. Rendering, formatting and variant production are drapery. There is no honour in painting your own drapery, and there never was.
An Old Anxiety in New Clothes
Every technology that industrialised execution provoked the same worry. Photography would end painting. Lithography would cheapen the print. The Factory would kill the aura, and Walter Benjamin wrote a famous essay about it. In each case the anxiety turned out to be about labour, while the durable questions turned out to be about authorship and honesty.
The workshop is a very old institution. It has always been a place where many hands executed one person’s intention, and it has always been governed by one rule that mattered more than the rest: be truthful about what the work is, and about whose judgment stands behind it. Software is a new kind of assistant. The rule is unchanged.
