When the true dawn begins to lighten the hills, it is in the west that its coming is foreshown, in that Duchy of Normandy, where in a century the fierce Vikings, who had been driven from the coast of Flanders in their forays from the Baltic, had become the finely tempered material out of which was to be forged, by the monks of Cluny, a Catholic civilisation that was to extend itself over all western Europe and endure for five centuries. Of the three great abbeys that were the centres from which radiated the great transforming force, Bec, Fécamp, and Jumièges, the two latter lie on our side of the Seine, with the third only ten miles on the other side, while St. Georges de Bocherville, intact except for its pestilential restoration, is of the same period, as is Cérisy le Forêt. Caen, with its two abbeys of the Conqueror, inestimable monuments of architectural history, is well to the west, with Evreux, Lisieux, Bayeux, and Mont St. Michel, but we have enough on the right bank to demonstrate the nature and the greatness of the work accomplished by Cluny and the Normans in a union cemented by a vital and crescent Christianity. Jumièges stands first, in its forgotten loop of the Seine, and is amazing, no less. But for its fine new fourteenth-century chevet, it was, at the time of the French Revolution, almost in its original state, but it was destroyed then, with Cluny, Avranches, St. Martin of Tours, and other priceless monuments, though by no means so completely. To-day its towering walls, rising above thick trees and greenery, are startlingly picturesque, but their great value lies in the revelation they make of what was possible in the earliest days of Christian recovery. The work was begun in 1040 and finished within twenty-five years, being followed immediately by the abbeys of Caen, as these were followed by St. Georges de Bocherville. The original plan was in each case about the same, the standard type, originally Latin, with Syrian, and probably Lombard and Carolingian, developments; cruciform, aisled both in nave and choir, the latter being of two bays only, with an apse, but no apsidal aisle and chapels as at Tours. The transepts are of two bays on either side the central tower, the end bays having galleries or tribunes, with a subordinate apse to the east, so forming, in the lower stage, small, low chapels. It is in the working upward from this plan that the significant developments appear, and both here and at Cérisy le Forêt, we find the order of round-arched arcade, high triforium of two arches under a containing arch, and a single clerestory window, Cérisy having as well an open clerestory arcade of three units. The system is clearly alternating, as in Lombardy and Tuscany, but there is no evidence that vaulting was ever contemplated; instead, I think it certain that great transverse arches on every other pier, supporting a wooden roof, were in mind, after the Syrian fashion, as it was later
