In page Peter Paul Rubens:

"

Paintings from Rubens's workshop can be divided into three categories: those he painted by himself, those he painted in part (mainly hands and faces), and copies supervised from his drawings or oil sketches. He had, as was usual at the time, a large workshop with many apprentices and students, some of whom, such as Anthony van Dyck, became famous in their own right. He also often sub-contracted elements such as animals or still-life in large compositions to specialists such as Frans Snyders, or other artists such as Jacob Jordaens.
