On the south of the line, one of the most beautiful as well as the best defined architectural provinces is that I have ventured to designate as Provence or Provençal. Its limits are very nearly coincident with those of Gallia Narbonensis, and “Narbonese” would consequently be a more correct designation, and would be adopted if treating of a classical style of art. It has, however, the defect of including Toulouse, which does not belong to the province, and consequently the name affects an accuracy it does not possess. It may, therefore, be better at present to adopt the vague name of the “Provence” _par excellence_, especially as Provençal is a word applied by French authors to literary matters much in the sense it is here used to define an architectural division. The whole of the south coast of France from the Alps to the Pyrenees belongs to this province, and it extends up the valley of the Rhone as far as Lyons, and is generally bounded by the hills on either side of that river. Perhaps the best mode of defining the limits of the Aquitanian province would be to say that it includes all those towns whose names end with the Basque article _ac_, consequently indicating the presence at some former period of a people speaking that language or something very closely allied to it, or at all events differing from those of the rest of France. It is only on the eastward that the line seems difficult to define. There are some towns, such as Barjac, Quissac, Gignac, in the valley of the Rhone, in situations that would seem to belong to Provence, and until their churches are examined it is impossible to say to which they belong. On the south Aquitania is bounded by the Pyrenees, on the west by the sea, and on the North by a line running nearly straight from the mouth of the Garonne to Langeac, near to Le Puy-en-Velay. The third is designated that of Anjou, or the Angiovine, from its most distinguished province. This includes the lower part of the Loire, and is bounded on the north-east by the Cher. Between it and the sea is a strip of land, including the Angoumois, Saintonge, and Vendée, which it is not easy to know where to place. It may belong, so far as we yet know, to either Aquitania or Anjou, or possibly may deserve a separate title altogether; but in the map it is annexed for the present to Poitou or the Angiovine province. In Brittany the two styles meet, and are so mixed together that it is impossible to separate them. In that district there is neither pure Romance nor pure Frankish, but a style partaking of the peculiarities of each without belonging to either. Besides these, there is the small and secluded district of Auvergne, having a style peculiarly its own, which, though certainly belonging to the southern province, is easily distinguished from any of the neighbouring styles, and is one of the most pleasing to be found of an early age in France.
