The world of monks inspired and shaped the civilization of the European Middle Ages for centuries. What do our contemporaries know about the daily life of monasticism, how they prayed, how they prepared for death, what they read, what they ate, how they slept? Leo Moulin is a recognized expert in the field of history and sociology of religion. He studied many different sources: chronicles and collections of customs, messages of the founders of orders and lives of saints, as well as scientific works devoted to this issue. The author convincingly and vividly shows how, trusting in the Providence of God, these people of fire, iron and faith lived in the Middle Ages.
