The occupation of the greater part of France by the English in the Hundred Years’ War would naturally result in an English influence being noticeable in its buildings, the contact of nations producing an exchange of art as of commerce. The Flamboyant may therefore be said to be the by-product of the Hundred Years’ War. There is documentary evidence that both at Rouen and at Evreux the foreign occupation did not interfere with the work going on at the cathedrals; indeed, at Rouen, two canons of York were received with the greatest courtesy by the chapter, and contributions were made by the English towards the completion of the Cathedral. The domination of the English was no hindrance to the progress of art in France, and as soon as the latter had freed itself and realised its national unity, its architects applied themselves heart and soul to the development of this style which was “borrowed from the enemy.” A long list can be made of buildings where the ogee arch and other typical features obtained in England, from the end of the thirteenth to the latter part of the fourteenth century, during which time no parallels existed in France. One of the most ancient examples is Queen Eleanor’s Cross at Northampton (1291-1294), where Flamboyant features show themselves. The tomb of William de la Merche at Wells (1302), Aymer de Valence at Westminster (1323), and many other early fourteenth-century examples, furnished by almost every cathedral, testify to the prevalence of the passion for the ogee motive of decoration. These are given in detail by M. Enlart as irrefragable proofs of the English origin of the Flamboyant style. The interior of the Cathedral of Rouen is considered by Mr. Bond to be curiously Romanesque in plan. Its nave bays are four-storied, an upper and lower pier arch with small triforium and clerestory. The upper pier arch might also be regarded as a triforium, for a passage-way runs along the sill of the arch and is continued behind the main piers on an elegant group of shafted corbels. These were originally intended to support a vault of a lower aisle. The east end is more dignified and has simpler factors, clerestory, triforium and pier arch. The glass is magnificent, dating from the thirteenth century. [Illustration: RUE DE L’HORLOGE, ROUEN]
