A tomb of Bishop Laurent Buti (d. 1710) is set against the wall, where the apse adjoins the nave. Rearward on the high-altar is a fine painting by an unknown artist of the Italian school. The old-time cathedral of St. Siffrein was plainly not of the poverty-stricken class, as evinced by the various accessories and details of ornamentation mentioned above. It had, moreover, in conjunction with it, a most magnificent and truly palatial episcopal residence, built by a former cardinal-bishop, Alexandri Bichi, in 1640. To-day it serves the functions of the _Palais de Justice_ and a prison; in the latter instance certainly a fall from its hitherto high estate. Built about by this ancient residence of the prelates of the Church is also yet to be seen, in much if not quite all of its pristine glory, a _Gallo-Romain arc de Triomphe_ of considerable proportions and much beauty of outline and ornament. As to period, Prosper Mérimée, to whom the preservation of the ancient monuments of France is largely due, has said that it is contemporary with its compeer at Orange (first or second century). The Porte d'Orange, in the Grande Rue, is the only _relique_ left at Carpentras of the ancient city ramparts built in the fourteenth century by Pope Innocent VI. XII CATHÉDRALE DE VAISON The Provençal town of Vaison, like Carpentras and Cavaillon, is really of the basin of the Rhône, rather than of the region of the snow-crowned Alps which form its background. It is of little interest to-day as a cathedral city, though the see dates from a foundation of the fourth century, by St. Aubin, until the suppression of 1790. Its former cathedral is hardly the equal of many others which have supported episcopal dignity, but it has a few accessories and attributes which make it notable. Its nave is finely vaulted, and there is an eleventh-century cloister, which flanks the main body of the church on the left, which would be remarked under any circumstances. The cloister, though practically a ruin,--but a well preserved one,--shows in its construction many beautiful Gallo-Romain and early Gothic columns which are exceedingly beautiful in their proportions. In this cloister, also, are some fragments of early Christian tombs, which will offer unlimited suggestion to the archæologist, but which to the lover of art and architecture are quite unappealing.
