This essay visualizes the overall trend of theartist’s painting production and situates the pupils’ training periods in the master’s career timeline. The analysis shows thatDe Lairesse’s painting production fluctuates with the change of the quantity and quality of pupils present in his workshop.This essay further reveals the workshop’s participation in large-scale commissions for decorative paintings, which alsoexplains why and when the master had more time for making collector’s paintings by himself.
