Some statues on one of the transept doorways are curious examples of how a fraud may be perpetuated. They represent, without doubt, some members of the royal house of David, but at some period they were said to be kings of the Capétien line, and as such, casts were taken and sent to Versailles, where they figured as portrait statues of Hugues Capet, Robert, Henri, Philippe, Louis VI., and Louis VII. The capitals of the columns and the foliage ornament of these portals are vastly superior in style to the figures.

On each side of the western rose-window are some bands of black and white marble, after the manner of the churches of Pisa and Genoa, souvenirs, probably, of Suger's travels in Italy. Indeed, he tells us in the account of his administration that he took much trouble in preserving a mosaic which he had brought home and placed in the tympanum of one of the doors. This was unfortunately replaced, in 1774, by a bas-relief of the meanest possible workmanship.

The interior consists of a nave and two aisles, with a chevet of seven chapels at the east end, considerably raised above the level of the nave. Access to these chapels is gained by a flight of steps on each side of the High Altar, and under them is the royal crypt. The whole of the east end of the church, the double aisles, with their single-shaft pillars, the chapels, the vaulting, and the glass, form a mass of colour, and a most beautiful coup d'œil;[18] indeed, there is but one eyesore in the whole building, the aforesaid series of windows representing Louis Philippe's heroic deeds. Blue swallow-tailed coats and white trousers scarcely form a costume which is either effective or appropriate as designs for church windows.

The wood carving of the stalls is of the 15th century, and was brought from the abbey of S. Lucien-lez-Beauvais; the inlaid marquetry work at the backs of the seats is from the Château de Gaillon, built by Cardinal d'Amboise. Many of the misérérés have the usual quaint conceits which one sees everywhere. Portions of the old glass were preserved by Lenoir in the museum of the Petits-Augustins during the stormy period, and were afterwards replaced in the windows of the apse. They consist mainly of fragments of a tree of Jesse, and may be found in the chapel of the Virgin. There are in all eleven lozenge-shaped medallions representing scenes in the life of Moses, and mystical subjects from the Apocalypse, bearing inscriptions by Suger. Upon the medallion of the Annunciation, the good abbot himself is portrayed prostrate before the Blessed Virgin. In one or two of the other chapels there are a few fragments of the legend of S. Laurence.

Of the early kings of France Dagobert was the first to be buried at S. Denis, and his memorial tomb (much restored) still stands on the right of the High Altar. Clovis and Clotilde were buried in the crypt of the first church erected upon the site of S. Geneviève, then called the Church of the Holy Apostles. Childebert was laid in the church of the Abbey of S. Vincent (founded by him), afterwards called S. Germain-des-Près. Chlodoald was buried at S. Cloud; S. Radegonde, wife of Clotaire I., at Poitiers; Chilpéric and Frédégonde laid the body of one of their children in the first church of S. Denis. Besides Dagobert I., his queen, Nanthilde, and their sons, Sigebert II. and Clovis II. were buried at S. Denis; and although it is thought that other Merovingian princes also received burial there, many repose at Chelles, S. Waast d'Arras, S. Bertin, S. Etienne de Choisy, Metz, Angoulême, S. Romain de Blaye, Jumièges, and S. Crépin de Soissons. The monuments of Charles-Martel, Pépin and Berthe, Carloman, Charles the Bald, Ermentrude, Louis, Carloman, and Eudes were all at S. Denis. Charlemagne was buried at Aix-la-Chapelle, where the magnificent châsses containing his skull and some of his bones may still be seen. His descendants were distributed all over Europe: at Köln, Mainz, Prüm, Regensburg, Loresheim, Oettinghen, Reichenau, Audlau, Verona, Milan, and Piacenza; those in France, at Metz, Sens, Bourges, S. Laurent, S. Sulpice, Tours, Angers, Lyon, Portiers, Compiègne, Reims, Péronne, and Soissons.

From Hugues Capet to Louis XV. most of the kings were interred at S. Denis; but it must be borne in mind that almost all the tombs of the earlier sovereigns are modern, either wholly or in part. In the 13th century the strange custom came into fashion of dividing the bodies of royal personages, and burying the parts in different places. The Benedictine monks of S. Denis protested against this division of valuable property, asserting their right to possess the entire remains of the kings; but the Dominicans and the Cordeliers contested these claims, and subsequently gained permission for their own churches to share in the spoil. Later on, other religious orders obtained the same privileges; and the ladies of Val-de-Grâce were distinguished by the possession of the hearts of nearly all the royal princes and princesses from Anne d'Autriche, the founder of the monastery. Naturally, when each defunct sovereign was divided into three portions—the body, the heart, and the intestines—great opportunities were afforded to architects and sculptors; and we thus find three marble monuments with recumbent figures erected for the remains of Charles V., that at S. Denis containing his body, while Rouen and Maubuisson respectively possessed his heart and his et ceteras.[19] Francis I.'s heart was placed in an exquisite urn in the church of the nuns of Haute-Bruyère; while his body was buried in the grand monument at S. Denis. The urn was the work of Pierre Bontems, and is now in the same chapel as the tomb, which was the joint work of Philibert Delorme and Bontems. The beautiful group of the Three Graces, by Germain Pilon, formerly in the church of the Célestins, and now in the Renaissance Museum of the Louvre, supported an urn containing the heart of Henri II.;[20] the hearts of the 13th and 14th Louis, enveloped in shrines in the form of silver Angels, being the property of the church of the Jesuits. The number of monuments erected at S. Denis to the memory of the families of the sovereigns was small; and none of them were to be compared, as works of art, to the beautiful tombs of the Dukes of Bourgogne and of Brétagne at Dijon, at Bruges, and at Nantes. Most of the princes of the different families, the Condés, the Contis, the Valois, the Bourbons, &c., had founded chapels or monasteries where they were afterwards buried; as, for instance, the Orléans chapel at the Célestins, which was celebrated for its magnificence.[21]

None of the monuments of the early kings are anterior to the 13th century; consequently, even the original portions of the effigies which remain cannot be looked upon as in the slightest degree portrait statues. On the other hand, the magnificent tombs in bronze, and the brasses which adorned them, erected to the memory of Philippe Auguste, S. Louis, and his father, and which were destroyed centuries ago, were most probably as valuable as contemporary portraits as they were for their workmanship; likewise the 13th century effigies which remain are remarkable for the beauty of their workmanship. Louis IV. was the last prince who was laid under a simple stone monument. The last tomb erected was that of Henri II., the sovereigns who followed him having had no memorials. They were laid together in one great crypt, and when disturbed by the Revolutionists for the sake of the lead of their coffins ("of the coffins of our old tyrants let us make bullets to hurl at our enemies"), there were fifty-four bodies arranged upon iron trestles side by side, Henri IV.[22] heading the list, and the Dauphin, elder son of Louis XVI., ending it. The monuments now occupy the same position that they did before the Revolution; and if we stand upon the raised platform of the apse behind the High Altar we can gaze down upon what may be called the history of France, from the artistic point of view, during four or five centuries. On the left, the 13th century tomb of Dagobert stands erect; beyond it, the Renaissance mausoleum of Francis I., one of the chefs-d'œuvres of that grand sculptor, Philibert Delorme. On the right, the enamelled brasses of the children of S. Louis and the tomb of Henri II. A mosaic effigy of Frédégonde, the Orléans monument, and the tomb of Louis XII. by the brothers Juste, of Tours, complete the list of important works, while all about are recumbent figures upon arcaded monuments. The resting-places of the abbots were simply marked by inscriptions or flat slabs. The historian of the Abbey, Dom Michel Félibien, records the number of thirteen stones of grand priors with effigies, besides the abbots' tombs.
