The Church of Notre Dame des Doms (A) occupies the summit of the rock, and is of much older date than the Pope’s Palace. The porch of this church (Fig. 47) is extremely interesting as an example of Provençal architecture so strikingly ancient in character as to have been long held to be a classic structure of the Lower Empire. It exactly resembles a Roman design in its general idea, forming, as it were, a compartment of a classic edifice, with a fluted Corinthian column at each side, and an arched doorway or opening between. On the columns rests an entablature, and the whole is crowned with a triangular pediment. The Corinthian capitals, the cornices with egg and leaf enrichments, the mouldings, imposts, &c., are all strikingly Roman in character. The inner doorway to the church is similar. Mérimée points out that the size of the stones used in this porch does not correspond with Roman work, being smaller than Roman large work and larger than Roman small work. Also that the stones of which the columns are composed are [Illustration: FIG. 47. CHURCH OF NOTRE DAME DES DOMS AND PALACE OF THE POPES, AVIGNON.] wrought with tails bonded into the wall (alternating right and left), which he regards as contrary to classic practice. The bull’s-eye of the tympanum is also not Roman, but might be an addition. It is probable that the sides of the porch were originally open. The date of this porch has been the subject of much discussion; but it seems most likely that it belongs to the early part of the eleventh century. It was at that date that architecture began slowly to revive; and this is probably one of the first efforts. Designers would then naturally fall back on the classic forms, of which examples were abundant around them. There are many instances in which the early mediæval architecture can be traced to Roman structures found in their vicinity. We have already met with one striking example at St Paul-trois-Châteaux; and it was previously shewn how the gates of Autun influenced the architecture of a large district, in which pilasters, copied from those of the Porte d’Arroux, are universally used instead of round shafts. We shall also presently see how the dome-topped campaniles of Provence are also copied from Roman monuments, such as that at St Remy; and how in almost all the churches throughout Provence Roman columns, caps, cornices, mouldings, and enrichments are freely imitated. But these imitations are generally incomplete, and invariably contain defects or omissions, which shew that they are imperfect copies, and not real Roman work. Such imperfections affect the details rather than the general style. In the instance before us, it is stated that the cornice of the antique part of the tower above the porch is copied exactly from that of the attic of the Arch at Orange.
