Granting, as one must, that this concealment of the transition is a beauty, one would still like to be quite sure that the Chartres scheme is the best. The Norman clochers being thrown out, and that at Vendome being admittedly simple, the Clocher de Saint-Jean on the Church of Saint-Germain at Auxerre seems to be thought among the next in importance, although it is only about one hundred and sixty feet in height (forty-nine metres), and therefore hardly in the same class with Chartres. Any photograph shows that the Auxerre spire is also simple; and that at Etampes you have seen already to be of the Vendome rather than of the Chartres type. The clocher at Senlis is more “habile”; it shows an effort to be clever, and offers a standard of comparison; but the mediaeval architects seem to have thought that none of them bore rivalry with Laon for technical skill. One of these professional experts, named Villard de Honnecourt, who lived between 1200 and 1250, left a notebook which you can see in the vitrines of the Bibliotheque Nationale in the Rue Richelieu, and which is the source of most that is known about the practical ideas of mediaeval architects. He came to Chartres, and, standing here before the doors, where we are standing, he made a rough drawing, not of the tower, but of the rose, which was then probably new, since it must have been planned between 1195 and 1200. Apparently the tower did not impress him strongly, for he made no note of it; but on the other hand, when he went to Laon, he became vehement in praise of the cathedral tower there, which must
