Escutcheon of Frans Banninck Cocq, Lord of Purmerland and Ilpendam
Quellinus took on private commissions from the Amsterdam mayors and their relatives, such as this design for the family coat of arms of Frans Banninck Cocq (1605–1655). He was Lord of Purmerend and Ilpendam and is chiefly known as the central figure in Rembrandt’s Nightwatch.
