Book of Hours (Use of Paris), c. 1420. The Boucicaut Master takes his name from the book of hours he made for Jean de Boucicaut (died 1421), marshal of France, who was taken prisoner by the English at the Battle of Agincourt in 1415. This talented artist, known for his tall, elongated figures with delicate features, exercised profound influence over Parisian manuscript painting during the first decades of the 1400s?a point illustrated by this volume.
