The Très Riches Heures du Duc de Berry (; or Très Riches Heures) is the most famous and possibly the best surviving example of French Gothic manuscript illumination, showing the late International Gothic phase of the style. It is a book of hours: a collection of prayers to be said at the canonical hours. It was created between c. 1412 and 1416 for the extravagant royal bibliophile and patron John, Duke of Berry, by the Limbourg brothers. When the three painters and their sponsor died in 1416, possibly victims of plague, the manuscript was left unfinished. It was further embellished in the 1440s by an anonymous painter, who many art historians believe was Barthélemy d'Eyck. In 1485-1489, it was brought to its present state by the painter Jean Colombe on behalf of the Duke of Savoy. Acquired by the Duc d'Aumale in 1856, the book is now MS 65 in the Musée Condé, Chantilly, France.
