Of all the cathedrals of France, Notre Dame de Paris is most firmly impressed on the minds of English speaking people. At least, it is more familiarly known by all who visit that delectable land, and perhaps rightly so. Poets have sung its praises, and writers of all ranks have used it in well-nigh every possible fashion as an accessory; indeed, books almost without number have been written about it, and around it. This is as it should be, for perhaps no great church is more worthy, or more prolific in material. For those who would probe deeply into its story, there is but one way to acquire an intimate knowledge thereof,--to undertake a course of reading and study in some such way as a lawyer sets about reading up on a great case. By no other method could be acquired a tithe of the commonly known facts regarding its past history; hence the impossibility of attempting to deal fully in a few pages with this great church, even in a perfunctory manner. The most that can be safely ventured upon, is to recount some of the facts. How many have really noticed that none of the diagrams, which show the ground-plan of this cathedral, indicate the existence of any transepts? Take, for instance, that which accompanies this volume, which, it may be said, is drawn correctly,--beyond the omission of a couple of pillars on either side of the nave, there is nothing to break into the long parallelogram-like structure, with an apsidal termination. As a matter of fact, there are a pair of very beautiful transepts, as most photographs of the exterior, and drawings of the interior, show. They are, too, in no way attenuated, and are only lost in the ground-plan by reason of the fact that they follow the very unusual arrangement of not extending laterally beyond the ample width of the nave and its chapelled aisles. The south transept facade, with the portal dedicated to St. Stephen, and two magnificent rose windows, is unquestionably more pleasing than the west facade itself as to design and arrangement.
