This is we think the experience of everyone who has the opportunity to see much of Notre Dame. The present writer during the course of his medical studies spent many months in daily view of the Cathedral and did a good deal of work at the old Morgue, situated behind the Cathedral. Even at the end of his stay he was constantly finding new beauties in {99} the grand old structure and learning to appreciate it more and more as the changing seasons of a Paris fall and winter and spring, threw varying lights and shadows over it. It was like a work of nature, never growing old, but constantly displaying some new phase of beauty to the passers-by. Mrs. Pennell resents only the restorations that have been made. Generations down even to our time have considered that they could rebuild as beautifully as the Thirteenth Century constructors; some of them even have thought that they could do better, doubtless, yet their work has in the opinion of good critics served only to spoil or at least to detract from the finer beauty of the original plan. No wonder that R. M. Stevenson, who knew and loved the old Cathedral so well, said: "Notre Dame is the only un-Greek thing that unites majesty, elegance, and awfulness." Inasmuch as it does so it is a typical product of this wonderful Thirteenth Century, the only serious rival the Greeks have ever had. But of course it does not stand alone. There are other Cathedrals built at the same time at least as handsome and as full of suggestions. Indeed in the opinion of many critics it is inferior in certain respects to some three or four of the greatest Gothic Cathedrals. It cannot be possible that these generations builded so much better than they knew, that it is only by a sort of happy accident that their edifices still continue to be the subject of such profound admiration, and such endless sources of pleasure after seven centuries of experience. If so we would certainly be glad to have some such happy accident occur in our generation, for we are building nothing at the present time with regard to which we have any such high hopes. Of course the generations of Cathedral builders knew and appreciated their own work. The triumph of the Thirteenth Century is therefore all the more marked and must be considered as directly due to the environment and the education of its people. We have then in the study of their Cathedrals the keynote for the modern appreciation of the character and the development of their builders.
