The Celtic remnant, that in the volcanic-torn uplands of middle France inflicted on Cæsar his sole defeat, lives always in the churches of Auvergne, so stubbornly indigenous, planted so sturdily, contriving decorative beauty from the regional varicolored lava stones. In the granite churches of Brittany endures all the aloof individuality, the sensitive independence, the tenacious traditionalism of the dwellers by the sea in the far-north outpost of France. We have our souls to keep, say the lowly Breton shrines, we have always been too busy doing that to find time to erect great churches. But once our neighbors, the Normans, taught us tower-building, our Celtic imagination leaped _au delà_ by their spires, so we raised our royal Kreisker which far out to sea welcomes home our Breton sailors. Architecture is history. Architecture is what the old Greeks said of history, "philosophy teaching by examples." The cathedrals of France prove that there is no supreme architecture where there is not liberty or the will to attain it. In 1109 the bishop-baron of Noyon granted his city a charter, the first communal written laws on record. In 1145 Noyon began to build the first Gothic cathedral of France. In the Ile-de-France, where from the nation's birth were lived its intensest hours, sprang up the churches which are the most national, the most racially French in character, Noyon, Senlis, Soissons, Laon, Paris. The history of architecture proves that without a right-minded national pride, ready to make sacrifices in order that it may transmit its high deeds to the future, no mighty monuments rise. In 1214 Bouvines' victory was won and French unity demonstrated. In 1220, not far away, was laid the foundation stone of Amiens Cathedral, the crowning achievement of the national art. A hazard, such juxtaposition? Ah, no. Nothing happens by chance in this science of the builder whose basic forces are long at work in silence. Architecture is the truthteller of history. The history of France, which in the XII and XIII centuries meant universal history, is written on the walls of the cathedrals built under Philippe-Auguste and his grandson St. Louis, during the full flowering of the new national art. And in the days when France was neither happy nor good nor great, when faith flagged, when a minority's blind greed of gold ended the international fairs, drove out the Jews, overtaxed the clerical church builders, when the crusading enthusiasm ended in a Templars' process, then the structural logic of Gothic architecture turned to pitiless geometry. So proclaim the cold, uninspired XIV-century churches, and few of them ever were built. It seemed almost as if the Gothic cycle had run its course. The XII century had seen its rise; the XIII century its apotheosis; the XIV century its decline. Was the last word said? Churches are not built by generations that live in ceaseless war, in misrule, or under a foreign yoke.
