Alliance Coat of Arms of Cornelis Calkoen and Maria van der Merct
In this drawing the Amsterdam artist Maria Monninckx surrounded the alliance arms that unite the Calkoen and Van der Merct families with a spectacular coloured floral wreath. A tiny garden tiger moth, a red admiral butterfly and a stem sawfly flutter around it. She achieved the brilliant colour by applying various layers of paint over one another and adding a touch of gold here and there.
