As we pointed out in Chapter II of the Introduction to Volume II, it is already plain from documentary evidence that the number of pupils working in Rembrandt’s studio must have been considerable. Attention was drawn to the status of these young artists as ‘leerjongens’ (apprentices) or ‘knechten’ (assistants), and their potential importance for the output of the workshop. Following on from the conclusions and suggestions put forward concerning works produced in Rembrandt’s studio by Isack Jouderville and Govaert Flinck in the early 1630s, the present chapter will deal with the workshop production of the years 1632–42 and, where directly connected, with the work of his pupils after they had set up on their own. Besides the various types of workshop piece, we shall consider the part played in this production by identifiable hands.
