From 7 to 10 March 2023, the Foundation welcomed two experts in stained glass, Isabelle Lecocq (IRPA) and Yvette van den Bemden (UNamur), who discussed diverse aspects related to the production and conservation of stained glass (historical evolution, commissions, techniques etc.). New avenues of research were presented, in particular with regard to the connections between stained glass and the paintings of Hugo van der Goes and Pieter Coecke van Aelst, the study of preparatory drawings (small-scale drawings, cartoons, etc.), and the iconographic study of small medallion panels and rondels. A particularly difficult question addressed during the seminar concerned the authenticity of the attribution of stained glass, which is complicated, since no stained glass window has been transmitted without alteration.
