The contents of cycles varied with date, location, and the purpose of the work. The Très Riches Heures du Duc de Berry (illustrated right) was designed for the personal use of a great magnate, and was unusually large, allowing all the typical elements to be used in many months. It combines astrological and calendar information at the top, with a combination of the agricultural life of the peasant, the life of the elite courtiers, and illustrations of the Duke's many castles in the background of several scenes.
