"What do we know about the employment conditions of construction workers in the Middle Ages? What were their rights and their duties? What form of collective organisation did they have? Jean-Michel Mathonière, an expert on compagnonnages (journeymen societies) and a member of the French Construction History Society (Association Francophone d'Histoire de la Construction), shares the research findings of his book 3 minutes pour comprendre les métiers, traditions et symboles des bâtisseurs de cathédrales (Understanding the trades, traditions and symbols of the cathedral builders in 3 minutes), published by Courrier du Livre in 2020."
