‘The main ribs of the vault spring from, or are rather continuations of the tall clustered pilasters, which are themselves continuations of the main piers; and from the points where each of the main ribs rise two other cross-ribs also spring. These at their points of intersection are adorned with crown-shaped bosses, for the most part enriched with carvings of foliage, coloured in part, which have been marred with colour-wash. Lines, in imitation of ashlar-work, have been painted upon the vault’ (Massé).[79] The piers in the nave and transept are alternately cylindrical and octagonal in section, and have supplementary cylindrical or octagonal columns; but in the ambulatory of the choir there are several piers circular in section, with octagonal bases and square plinths, but without any supplementary columns. Such plain round piers, which in England are called Norman, are rare in France. Examples of them are, however, to be found at Laon, Soissons and Paris. The capitals are rich and varied, and consist chiefly of foliage; those of the piers in the Chapel of the Seven Sorrows (Clocher Neuf), and, again, those of the Norman pillars, in the deambulatory of the choir opposite the shrine of Notre-Dame du Pilier, are remarkably fine. But the most noteworthy of the piers are the four ‘Toureaus,’ as they are called: the enormous piers at the intersection of nave and transept, which were intended to support the central tower and spire, and which rise sheer to the roof, in an unbroken line, to the height of 120 feet. Their faces are covered with a quantity of slender columns. The arcading of the triforium varies in width and character in the nave, the choir, and the transepts and the apse. The arches of the smaller bays into which each main bay is divided are pointed. The soffit is flat, with a round moulding at the inner and the outer edge. The capitals are richly carved with foliage; the bases are plain and severe. The clerestory is composed of pairs of tall lancet windows, with a rose window above them, which fill the whole available space in each bay. Of the glass we have spoken in the previous chapter. The _Flamboyant_ period is represented in the Cathedral by the spire of Jehan de Beauce and the _Chapelle Vendôme_, next to the south transept. It was founded in 1413 by Louis de Bourbon, and dedicated to the Annunciation. It has recently been restored. The style is incongruous with this massive transitional nave, but serves perhaps to accentuate the beauty of its masculine grandeur and reserve. The remains of S. Piat and S. Taurin are preserved here; the one is invoked for fair weather, the other for rain by the farmers of La Beauce.
