Victor Hugo writes in his classic gothic novel published in 1831 Notre-Dame of Paris (deutsch: The Hunchback of Notre Dame) about the cathedral: “This façade is a tremendous stone symphony, the gigantic work of a man and a people, uniform and yet assembled. A wonderful product of the collected forces of a time when the imagination of a craftsman, tamed by the genius of the artist, is available to everyone Stones imprinted in a hundred different shapes; in short, a human creation that is rich and powerful, like the divine creation itself”.
