It is more than reminiscent of St. Marc's at Venice, and is the most notable exponent of that type of roofing which employed the cupola in groups, to sustain the thrust and counterthrust, which was afterward accomplished by the ogival arch in conjunction with the flying buttress. Here are comparatively slight sustaining walls, and accordingly no great roofed-over chambers such as we get in the later Gothic, but the whole mass is, in spite of this, suggestive of a massiveness which many more heavily walled churches do not possess. Paradoxically, too, a view over its roof-top, with its ranges of egg-like domes, suggests a frailty which but for its scientifically disposed strains would doubtless have collapsed ere now. This ancient abbatial church succeeded an earlier _basilique_ on the same site. Viollet-le-Duc says of it: "It is an importation from a foreign country; the most remarkable example of church-building in Gaul since the barbaric invasion." The plan of the cathedral follows not only the form of St. Marc's, but also approximates its dimensions. The remains of the ancient basilica are only to be remarked in the portion which precedes the foremost cupola. St. Front has the unusual attribute of an _avant-porch_,--a sort of primitive narthen, as was a feature of tenth-century buildings (see plan and descriptions of a tenth-century church in appendix), behind which is a second porch,--a vestibule beneath the tower,--and finally the first of the group, of five central cupolas. The _clocher_ or belfry of St. Front is accredited as being one of the most remarkable eleventh-century erections of its kind in any land. It is made up of square stages, each smaller than the other, and crowned finally by a conic cupola. Its early inception and erection here are supposed to account for the similarity of others--not so magnificent, but like to a marked degree--in the neighbouring provinces. Here is no trace of the piled-up tabouret style of later centuries, and it is far removed from the mosque-like minarets which were the undoubted prototypes of the mediæval clochers. So, too, it is different, quite, from the Italian _campanile_ or the _beffroi_ which crept into civic architecture in the north; but whose sole example in the south of France is believed to be that curious structure which still holds forth in the papal city of Avignon. Says Bourassé: "The cathedral of St. Front at Périgueux is unique." Its foundation dates with certitude from between 1010 and 1047, and is therefore contemporary with that of St. Marc's at Venice--which it so greatly resembles--which was rebuilt after a fire between 977 and 1071. [Illustration: _Detail of the Interior of St. Front de Périgueux_] The general effect of the interior is as impressive as it is unusual, with its lofty cupolas, its weighty and gross pillars, and its massive arches between the cupolas; all of which are purely constructive elements.
