The Tr鋊 Riches Heures is the classic example of a medieval book of hours. This was a collection of the text for each liturgical hour of the day - hence the name - which often included other, supplementary, texts. Calendars, prayers, psalms and masses for certain holy days were commonly included. The month of October is depicted here by Duc De Berry October, the month of tilling and sowing, is represented along the left bank of the Seine. The view is from the vicinity of the H矌el de Nesle, the Duc de Berry's Paris residence, from approximately the same vantage point as in the month of June. In June the Limbourgs looked east, while here they turn toward the north; in June they painted the Palais de la Cit? former residence of the kings of France, while here they show the Louvre, the royal residence since the time of Philippe Auguste (reigned 1180-1223). Before us is the imposing mass of the Louvre of Charles V, the Duc de Berry's brother, as seen from the windows of the Duke's h矌el; it is rendered so scrupulously that we can make out its every detail. In the middle rises a big tower, the dungeon built by Philippe Auguste, whose outline is traced in the paving of the ch漮eau's cour carr嶪 (square courtyard). This dungeon, commonly called the Tour du Louvre, symbolized the royal prerogative; from here appanages were granted, and here the royal treasure was housed. In the miniature the dungeon hides the northwest tower, known as the Tour de la Fauconnerie, where Charles V kept the precious manuscripts of his library. But we can see the three other corner towers: to the right is the Tour de la Taillerie; then the eastern facade protected by twin towers whose outline is also visible on the courtyard paving; farther to the left is the Tour de la Grande Chapelle, followed by the southern facade, also with double towers.
