By 1400–16, the period of the famous illuminated manuscripts of the "Livre de Chasse" of Gaston Phoebus (Bibliothèque Nationale, Paris Ms Français 616), and the "Très Riches Heures du Duc de Berry" chaperons are to be seen worn by many figures. In the famous Calendar scenes of the "Trés Riches Heures", they are worn in the original form by the peasants working in the fields, both men and women (February, March and September), and huntsmen (December), and in the new form by some of the courtiers (January and May), who wear coloured and scalloped ones, probably of silk. However, the Duke himself, and the most prominent courtiers, do not wear them. In the "Livre de Chasse" they are most often worn by the lower huntsmen on foot in the original form, though they and mounted hunters also wear them on top of the head. Figures often have a hood chaperon and a hat as well. Only the original form (trimmed with fur in one case - fol.51V) is worn by the very highest-ranking figures.
