The Duke was an important art collector of the era; among the works he commissioned was the Très Riches Heures du Duc de Berry. The tomb itself is one of the major art works in the chapel. It was made between 1391 and 1397 and is an important work of medieval sculpture, made between 1422 and 1428 by the sculptor Jean de Cambrai. The ensemble of sculpture includes the marble tomb of the Duke, with his symbolic animal, a bear chained and muzzled, at his feet. Nearby are statues of the Duke and Jeanne of Boulogne, both remakes attributed to the sculptor Jean Cox in about 1710. The tomb originally featured a collection of forty sculpted mourners, made of marble and alabaster. These have now been largely scattered to different museums.
