“Workshop: Refers to those artworks produced primarily by assistants from drawings or cartoons by a major artist, usually under his or her supervision. Rubens, for example, would complete the final work, after leaving most of the preliminary details to his workshop. The degree of his intervention was reflected in the cost of the work.”
