We now approach the country in which the peculiar elements of the Provençal style become distinctly apparent. About four miles north-east from Pierrelatte, the ancient town of Garde Adhémar may be seen towering aloft on the crest of a bold promontory about 500 feet high. This town contains a Romanesque church with an eastern and western apse, after the German fashion, a rather remarkable feature here, but showing, like the ornaments already referred to, an influence from the Rhine. The side aisles are vaulted with quarter-circle arches, and the exterior is finished with a small belfry and steeple. About six miles to the south-east of Pierrelatte lies the village of ST PAUL-TROIS-CHÂTEAUX, where another very remarkable church is found. The town was of some importance from Roman times downward, and retained its bishop’s see till the Revolution. Several fine Roman sculptures have been found in the locality, and are preserved in the Calvet museum at Avignon; and a few remains of Roman structures and columns are still to be seen. But the most interesting edifice in the town is the ancient cathedral of the twelfth century. As this is the first building we have met with which is characteristically Provençal in style, so it is also one which preserves in a very distinct and marked manner the traditional Roman [Illustration: FIG. 46. ST PAUL-TROIS-CHATEAUX. _Part of Exterior (from Révoil)._] features of that style. The annexed geometric view of one of the exterior bays (Fig. 46.) shews how close is the imitation in the Provençal architecture of the twelfth century of that of the Roman structures which no doubt then existed on the spot. The pilasters, crowned with their complete entablature of architrave, frieze, and cornice, and filled in with an intermediate arcade, might be part of a Roman amphitheatre (such as those at Nimes and Arles); and indeed it is supposed that traces of an ancient amphitheatre have been discovered at St Paul. Every detail might belong to the Lower Empire. The ornaments of the cornice are directly imitated from the modillions and leaf enrichments of Roman work; and the egg and dart, and other classic details are freely used throughout. The interior ornament is equally Roman in design. The east end is terminated with an apse, which has eight fluted columns. The two side aisles are covered with half wagon vaults, and the nave, which is unusually high, with a simple tunnel vault. This locality brings us for the first time into contact with a tradition of which we shall find many traces in various parts of Provence, viz., that the Gospel was introduced into this country by the family of Lazarus, and some other contemporaries of Christ, who had been driven hither by persecution. At St Paul the story goes that the first bishop was the blind man whose sight was restored, and who assumed the name of Restitutus.
