Rome gave the basilica plan to western Europe, which for centuries continued to build its churches as oblong halls with a small apse at one end. The hall, or nave, consisted of a central vessel with side aisles that were divided from it by piers. In the treatment of vaulting and the method of stone laying Romanesque architecture also derived from Rome. Byzantine influences certainly were important, but they affected the decoration more than the plan or the structure; the use of the Byzantine cupola was merely occasional. The Romanesque masters copied the ivories and miniatures of the Eastern Greeks till, in time, they turned to nature for their models, and then their work took on new life and evolved into the glory which is Gothic sculpture.
While some have laid stress on the Oriental influences, rather than those of Rome, in the formation of Romanesque art, others have overemphasized the personality and fantasy introduced into French architecture by the Barbarian invasions. No doubt the influx of new blood added new elements, but since knowledge of the invaders’ art is fragmentary, there can be no scientific base for the theory. Composite, certainly, were the causes for the new spirit which animated architecture after the Carolingian day, but it is safe to say that the influence of Rome predominated.
In the course of the centuries the Roman basilica was modified by the Catholic liturgy. For catechumens, or penitents, was made the porch, or narthex, before the western end. Tribunes were built over the side aisles.[5] Increased church ceremonial brought about a development of the choir. The custom of burying the dead in crypts under the main altar originated the raised chancel. Between the choir and the nave the builders began to insert a transverse nave called a transept.[6] Such an enlargement enabled the congregation to approach closer to the altar ceremonies; only the bigger churches built transepts in the XI century. Then the liturgical writers saw in a transept the extended arms of the Cross, and it was in that spirit the XIII-century transepts were made—their symbolism was posterior. The first ambulatories were no doubt built in churches which possessed some revered relic, to facilitate the passage of the pilgrim crowd. (The term ambulatory will be used to designate the continuation of the choir aisle round the apse.) Before long that curving processional path, with radiating apsidal chapels opening from it, was taken to represent the crown of thorns about the Sacred Head. “All things as pertain to offices and matters ecclesiastical be full of divine signification and mysteries, and overflow with a celestial sweetness: if so be that a man be diligent in his study of them, and know how to draw honey from the rock and oil from the hardest stone.” So wrote William Durandus, the XIII-century French bishop whose Rationale, or treatise on church symbolism, was an inspiration for centuries and, next to the Bible, the most frequently printed book of the older times.[7]
Despite a host of additions to the basilica of Rome—transept, ambulatory, a long choir, apse chapels, towers—despite the discarding of the classic orders and of antiquity’s use of a veneer of finer stone (the Romanesque builder used the unadorned stone of his own region) the church of western Europe remained, in general plan, a Roman basilica. Like Rome, they covered their main vessel by a flat wooden roof, although they knew how to build barrel and groin vaulting.[8]
Now a wooden roof is an easy prey for fire. Such roofs, a succession of long-continued invasions, and the faulty construction of Merovingian and Carolingian churches are accountable for the fact that in France to-day is no church that predates the year 1000. Some portions of ancient wall are embedded in later work, and some few early crypts are intact. But to speak with certainty of Merovingian and Carolingian architecture is impossible, though they formed the incubating phase of Romanesque art.
In France the IX and X centuries were periods of overwhelming disaster. In the Midi were Saracen incursions. In northern and central France Norman pirates wiped out Charlemagne’s revival of art. As far as Poitiers and Clermont the Northmen’s path of destruction extended. “Look where you will,” wrote Flodoard, the chronicler, “the sky is red with fires.” To the litany was added a new invocation—A furore Normannorum, libera nos, Domine.
The falling to pieces of Charlemagne’s civilization and the general return of social disorders have led to an overdramatic contrasting of the year 1000, when mankind, in terror, anticipated the ending of the world, with the rebirth of hope and of building energy, when the dread day had passed. Whenever the gaunt horses—famine, pest, war, and death—are afoot, humanity is prone to look for the fulfillment of the apocalyptic prophecy. Previous to the X century the final day had been awaited, and the same superstition was to seize on the world’s imagination in following centuries.
The X century was certainly a desperate age. Fifty years of it were famine, and on the highroads people were killed for food. But the evils did not cease precisely with the year 1000; also it should be noted that a certain number of churches were begun before the XI century opened. However, to mark the start of a new art life the year 1000 is a convenient date if we bear in mind that it was not a sharp division between Carolingian and Romanesque architecture, since a gradual evolution took place. All through the XI century the vital renewal of architecture went on, and churches were built which, to this day, are unrivaled for their profound religious spirit. They exist to tell us that in the harsh life whence they emerged there were enlightened cases. They vindicate, by their grand simplicity and detachment of soul, the men who built them. Never was an art less one of routine than this of the so-called hidebound monks, an art of a people reborn, full of youth’s daring, an art that was never to have an old age, eager, untiring, experimental, an art that fitly generated the most scientifically sound of architectures—Gothic.
The heterogeneous races, Celtic and Gallo-Roman, Germanic, and Norse, whose conflicts long had held France in anarchy, were at last welding into one people. The advent of a vigorous third dynasty, under whose leadership social conditions improved, was another cause of art’s rebirth. Not long after 1000 the bishops formulated the Trève de Dieu, by which peace was enforced on the turbulent lords from Wednesday night to Monday morning. With interval of peace came commerce and wealth and the security necessary for works of the imagination. The rebuilding of churches was inevitable.
Invasions and wholesale conflagrations had impressed on the mediæval mind the necessity of a church roof more durable than wood, but a masonry vault over a wide space was a constructive feat too difficult to be achieved immediately. In fact, up to the very end of the XI century, though the builders had succeeded in vaulting with stone the crypt, the apse, and the side aisles, they continued generally to cover the wide central vessel in wood. However, the fecund idea was at work. From the time that it took possession of their imagination, to the day when Gothic, its fulfillment, was clearly enunciated, there was over a century of continuous effort—roughly speaking, from the year 1000 to the memorable day in 1144 when was dedicated the first truly Gothic monument of considerable size—the abbey church of St. Denis. Within that energetic span of years is embraced the Romanesque architecture of France.[9]
The monk, Raoul Glaber, wrote an account of the rebirth of architecture after the year 1000. It has been quoted to weariness, but is none the less a valuable contemporary record. The whole earth, he says, as of one accord seemed to throw off its tatters of old age and to reclothe itself in a white mantle of churches. The monastery in which lived monk Raoul, St. Bénigne, at Dijon, was one of the first to inaugurate the new century, and its present crypt dates from the year 1001. Soon after 1017 the monks of Mont-Saint-Michel, in the far corner of Normandy, began a new church, to which belonged part of the present nave. At Chartres, Bishop Fulbert undertook to rebuild his cathedral after the fire of 1020, and the vast crypt which to-day astonishes every beholder was his work.
