The exhibition around the book Études d'un dessinateur (Studies by a Draughtsman) presents a work of great depth on the art of drawing. The author, Jean-Baptiste Stienne, has followed a path marked by inspiring encounters and formative experiences, not least his early discovery of Eugène Viollet Leduc's medieval encyclopaedia. His book, published in 2020, is a reference for those who want to explore drawing in a historical and practical way.
