The claim of Italy to be the first to use the diagonal ribs is denied by most French archæologists, but is put forward by the Italian scholar Rivoira and by Mr. Arthur Kingsley Porter.[12] The latter cites the church of Sannazzaro Sesia as showing proofs that its high nave was Gothic vaulted by 1040. For a century, he says, the Lombard churches used diagonals, especially in Milan, where wood was scarce and it was easier to build permanent brick ribs under the groin vault than to mold the groin on a temporary substructure. Diagonal ribs were invented, he thinks, as a device to economize wood. That may be true of the Lombard churches, of which he has made an elaborate study. And it may be true that the use of such diagonals filtered into Provence and Languedoc, where appeared some early Gothic vaults sporadically before 1150, at Fréjus, Marseilles, Maguelonne, and Moissac, all with the rectangular profile of the Lombard type. The theory he advocates does not prove why the Ile-de-France masons could not themselves, without hint from Lombardy, have stumbled on the new feature which was to revolutionize the builder’s art. Why should we prefer his explanation for the first use of diagonals—the desire to economize wood—to that advanced by the French scholars—the effort to brace a falling groin vault?
Mr. Porter acknowledges that not a single Lombard church was rib-vaulted throughout, that the Lombard architects never counterbutted their diagonals properly, that their vaults proved unsatisfactory, so that after 1120 they returned to their groin and barrel vaulting, or used timber roofs, in those regions where wood abounded. The destruction of Milan through the German invasion, in 1162, was a fatal blow to Lombard architecture. We can only conjecture how northern Italy might have worked out the problem of stone roofs. The best definition of Gothic, thinks Mr. Porter, is Professor Moore’s, which concludes thus: “Wherever is wanting a framework maintained on the principle of thrust and counterthrust, there we have not Gothic.” The Lombard churches never met the vault thrust with counterthrust of buttress. Surely not in Lombardy was conceived the new system of construction?
S. Ambrogio at Milan was cited as l’œuvre initiale, till it was proved that it was built not in the IX century, but after 1067; and as later disasters necessitated reconstructions, none of the present diagonals was extant before 1198. S. Abondio at Como, consecrated by Urban II, in 1095, has some very early intersecting ribs, but they are more a step toward the new system than a true Gothic vault, since the ribs merely reinforce and do not carry the cells.
M. Camille Enlart contends that the systematic use of Gothic in Italy was not earlier than the second quarter of the XIII century, and was brought across the Alps by French Cistercian monks. Though for centuries Italy used it, she apprehended its constructive principle imperfectly. Because she possessed a Niccola Pisano, a Giotto, a family of Cosmati to veil the poverty of her Gothic skeleton with details of consummate beauty, criticism is silenced. Her best Gothic monument, the cathedral of Siena, was insecure because of technical errors. Always was Italy adverse to showing the mechanism by which an edifice stood; few flying buttresses were ever built south of the Alps. She preferred the classic wide spacing of piers, an unencumbered interior, and small windows against her hot sun. Who remembers that he is in a Gothic church when in the somber cathedral of Florence? Its long nave is divided into four bays where a northern church would have used eight. For Italy the Renaissance was a whole-hearted return to a national art which she could fully understand.
No people outside of France better understood and developed Gothic art than the English. Their claim to priority is based on the date of the cathedral of Durham, whose choir-aisle diagonals Mr. John Bilson says are as early as 1093. Since those diagonals show no hesitation, they must have been preceded by others. Where in England are there to be found the earlier trials? The English claim is practically a Norman one, and Normandy’s experimental work in Gothic vaultings remains to be traced. Rivoira claims that Lombard influences predominated in the formation of Normandy’s Romanesque school. Can the Norman be said to have discerned in diagonals their immense possibilities any clearer than had the Lombard?
Those among the French archæologists who have disputed the Norman claim to priority say that the principal span of Norman and English churches was covered with timber roofs far into the XII century. We know that the Gothic vaulting of the two abbey churches of Caen were XII-century additions, and M. de Lasteyrie thought the same was true of Durham, though Mr. Bilson has convinced MM. Enlart and Lefèvre-Pontalis that Durham’s choir-aisle vaults are an original part of the cathedral begun in 1093. Not till 1174, when Guillaume de Sens began Canterbury Cathedral, did French Gothic architecture, in its plenitude, appear in England.
The question of priority remains an open one. It might almost be said that vaulting with intersecting ribs began to appear here and there simultaneously, that if it had not cropped out in the Ile-de-France, it would have appeared in Normandy, or vice versa. And not long after them, the builders in Burgundy and Anjou began to use it. Before 1150, isolated samples of the Gothic rib vault appeared at Vézelay, Poitiers, Bordeaux, Quimperlé, Moissac, St. Gilles, Marseilles. The hour was ripe for the solution. Gothic architecture was the spontaneous invention of French builders at the dawn of the XII century, at a time when the poetry of France was imposing itself on the whole of Europe.
L’œuvre initiale will never be known. However, there was a region where the early use of the ogival vault was not accidental, but systematic, one spot in the heart of France where it immediately made a school, since there it found no strong earlier traditions to overcome, where it became a living organism and went through a succession of logical developments until it had taken on the main characteristics of the new art. There is one center from which Gothic architecture spread out with slow, sure march into the neighboring regions. In the Ile-de-France, all the trials were summed up and developed by Abbot Suger at St. Denis. From 1140 to 1144 he wedded definitely the pointed arch with the diagonal rib.
The French masters, who have contended that the Ile-de-France is the cradle of Gothic architecture, have had lesser controversies among themselves as to which special portion of the royal domain led in the evolution. M. Woillez, a pioneer, considered the environs of Beauvais the favored spot; M. Saint-Paul looked to the districts between Normandy and Paris; M. Enlart sought the nucleus in Amiens diocese in Picardy; and M. Lefèvre-Pontalis chose the classic diocese of Soissons. The two latter masters have modified their views since studying Durham’s vaults, and they may modify them further in regard to Lombardy’s early use of diagonals. The controversy is not closed.
The France of that day was more a feudal confederation than a united kingdom, and some of the king’s vassals ruled territories larger than his own. If the feeling of nationality is created as much by great achievements in common, as by political boundaries and the ties of blood, if, as all now agree, the enthusiasm of the Crusades, those holy wars against a common foe, helped to weld the rival sections of France into one nation, surely that other enthusiasm of the day, those other Gesta Dei per Francos, the building of the Gothic cathedrals, played an important part in forming the national soul. From end to end of France they were building when at the battle of Bouvines a French king united with the jealous barons, with clergy and with burgess and with villein in a common defense of their native land. King, clergy, lords, and people fought at Bouvines, and king, clergy, lords, and people built the big national churches. All the energies of the times went to their making, all the primitive strong purposes, all the newly stirred intellect of the schools. Science was as needed for them as inspiration, for without the long manual training of the guilds, the mystic glow had not sufficed.
There has crept into various architectural manuals, since first M. Viollet-le-Duc voiced it, a theory which scarcely needs refuting, so disproved is it by modern research.[13] Gothic art is considered as the layman’s expression of revolt against the Romanesque art of the monks, an idea that denies the structural sequence of the two phases of the same art, and would present Gothic as a reaction against its predecessor, instead of its supreme development.
We read that a cathedral was built as a sort of assembly hall for the rising communes, and not pour loger le bon Dieu. Now in every known case it was the bishop who started the rebuilding of each cathedral, and the works usually began with the choir, the part of a church suitable only for the cult. Even when a bishop, in his character
