maxxxmodelz, In the typical studio system, the "master" got the commission and made the cartoon to his client's specs. He probably did most of the underlying drawing from sketches made on site. (If you look at the pencil drawings Hans Holbien the Elder made of the members of Henry VIII's court, you can see a remarkable freshness and liveliness.) The assistants ground the pigments and then slowly graduated to painting backgrounds, fabric, hands, and wings while the "master" went along and finished up the faces. Who got the credit? Yeah, the guy who got the commission and who did the final touches. The other dozen helpers are ignored, despite doing 95% of the painting. Does that make the piece less a masterpiece? Nope. From the mind of the artist, it speaks to us. Carolly
