During these centuries, "deluged with blood," the language must have been in a state of fusion. We know that, for the earlier epochs at least, no one could write his name except a cleric, and agreements were all signed with a cross. There was no general social movement, only incessant changes in the balance of power between kings and nobles. Brutal, unreasoning, material in the real sense of the word, despite their reputation as ages of faith, these centuries were destitute of progressive elements, and there was little or nothing to cause the speech to refine or develop. Literature and Latin died together. The Gallic tongue left traces in the speech of the South and there are several Provençal words in Irish and Welsh and in the language of the districts of the Vaudois showing their common Celtic origin, if one may judge from the first words of the Lord's Prayer:—

Vaudois. Irish.
"Our narme ata air neambh "Ar nathair ata ar neamb
Beanish atanim." Naemhthar hamin."

Strange to say, the Franks left scarcely any trace in the speech of the country. Wide as were the conquests of this people, with Charlemagne for Emperor in later days, their victory did not extend to the language.

Latin, as we have seen, flagged in the fourth century, and was finally extinguished about the middle of the ninth century.

This breaking up of the speech of the Romans into Romance forms a curious analogue to the breaking up of the Roman architecture into Romanesque. This latter change took place after the formation of independent States had superseded the old centralising Imperial idea.

Architecture, in its turn, developed different local styles, all deriving their character from the Roman and all called by the general name of Romanesque.

The chief peculiarity of Provençal Romanesque is in the pointed vaultings of the churches as distinguished from the familiar round arch of the Roman work.

The date of the introduction of the pointed arch into Gaul is a vexed question, but it is certain that it arrived earlier in Provence than in the North of France. It was found easier to build, and it "exerted less thrust on the side walls."[26]

But it was used in Provence for utilitarian reasons only, and it curiously happened that the South abandoned the pointed arch just when the North began to adopt it for decoration. The South preferred the round arch for this purpose, and as the architects grew more skilful they were able to cope with its difficulties, and thus—contrary to the usual rule—the pointed form in Provence denotes greater antiquity than the round vaulting. In the North, of course, it is exactly the reverse.

Byzantine influence was introduced into the South by the trade channel through France with the Levant, of which Perigueux in Acquitaine was a centre, and here the Venetian traders built a church on the plan of St. Mark's at Venice. This church of Perigueux was taken as a model by local architects who introduced the Byzantine dome and the aisleless nave; this latter being also a Byzantine feature, which may be seen in some of the churches of Toulouse for instance. Byzantine, or possibly merely late Roman influence is shown in the polygonal form of the apses and cupolas, "in the flat arches employed to decorate the walls, in the mouldings with small projections and numerous members; in the flat and delicate ornament; and in the sharp and toothed carving of the foliage."
