The Chartres window for Charlemagne is, alongside the shrine of Charlemagne in Aachen, the most significant artwork created for him. Here, he is depicted as both emperor and saint. To the people of the Middle Ages, he was brought to life through the legends and poems that were repeatedly told. In Chartres, a special monument was erected in his honor, and his biography was rewritten. Sophia-Janet Aleemi now recounts it image by image, skillfully and fascinatingly explaining the long-forgotten backgrounds as well as some connections that have never been considered before. Through her examination of the window, the author has succeeded in opening up a completely new perspective on the image of Charlemagne.
