Its size is not commonly accredited great, but for a fact its nave is over fifty-five feet in width; greater than Chartres, and nearly as great as Amiens in the north. This is a comparison which will show how futile it is not to take into consideration the peers, compeers, or contemporaries of architectural types when striving to impress its salient features upon one's senses. This immense vault is covered with a series of cupolas of a modified form which finally take the feature of the early development of the ogival arch. This, then, ranks as one of the early transitions between barrel-vaulted and domed roofs, and the Gothic arched vaulting which became so common in the century following. As to the general ground-plan, the area is not great. Its Romanesque nave is stunted in length, if not in width, and the transepts are equally contracted. The choir is semicircular, and the general effect is that of a tri-apsed church, seldom seen beyond the immediate neighbourhood of the Rhine valley. The interior effect is considerably marred by the modern mural frescoes by Bézard, after a supposed old manner. The combination of colour can only be described as polychromatic, and the effect is not good. There are a series of Roman capitals in the nave, which are of more decided artistic worth and interest than any other distinct feature. At the side of the cathedral is the _Chapelle des Innocents_, the ancient chapter-house of St. Caprais, now used as the chapel of the college. Its façade has some remarkable sculptures, and its interior attractions of curiously carved capitals and some tombs--supposed to date from the first years of the Christian era--are of as great interest as any of the specific features of the cathedral proper. XII STE. MARIE D'AUCH The first bishop of Auch was Citerius, in the fourth century. Subsequently the Province d'Auch became the see of an archbishop, who was Primate of Aquitaine. This came to pass when the office was abolished or transferred from Eauze in the eighth century. The diocese is thus established in antiquity, and endures to-day with suffragans at Aire, Tarbes, and Bayonne. The cathedral of Ste. Marie d'Auch is not of itself an ancient structure, dating only from the late fifteenth century. Its choir, however, ranks among the most celebrated in the Gothic style in all Europe, and the entire edifice is usually accorded as being the most thoroughly characteristic (though varied as to the excellence of its details) church of the _Midi_ of France, though built at a time when the ogival style was projecting its last rays of glory over the land. [Illustration: STE. MARIE _d'AUCH_] In its general plan it is of generous though not majestic proportions, and is rich and aspiring in its details throughout.
