In 1227 Beauvais planned a new cathedral, spurred on thereto by the magnificent nave rising in neighboring Amiens. But the works were not started till 1247, for the bishop, more a feudal baron than a pastor, was for a time entirely engrossed in mercenary wars in Italy and in quarreling with Blanche of Castile, the queen-regent. Finally Bishop Milon began his cathedral in Beauvais on a scale beyond the resources of the diocese. Despite his own and the chapter's generous donations, and the exemption of workmen and all building material from taxes, the choir was not finished till 1272, two years after the choir of Cologne. Scarcely was it done when, in 1284, its upper vaulting fell; a few years earlier a partial collapse had occurred. To remedy the disaster new piers had to be inserted between the old ones, which explains the sharp-pointed arches of the pier arcade. Only in the ambulatory, which was untouched by the falling masonry, is the original vaulting to be found. The required addition of flying buttresses was no improvement to the symmetry of the exterior. Instead of being able to proceed to the erection of a nave, forty years were wasted in repairs. Then came the calamities of the Hundred Years' War when building activities flagged all over France. Never again were profiles to be virile. The apogee hour of Gothic was forever past. With English, Burgundian, and French troops roving the country, Beauvais was kept on the alert. In 1429, the citizens, roused by Jeanne d'Arc's success at Orléans, expelled their bishop, who was in sympathy with the foe, and was none other than the unworthy Pierre Cauchon, soon to sit as miscreant judge at the Maid's trial in Rouen. Two years after Jeanne had been burned, Beauvais was besieged by English troops, and so gallant was the behavior of the women of the city, notably Jeanne Hachette, that forever after was accorded to them the right to march in the place of honor in all processions, directly behind the clergy. When the Duke of Burgundy, England's ally, besieged the city in 1472 he burned the episcopal palace, to which the two sturdy towers near the _Basse-OEuvre_ originally belonged. Once more the women of Beauvais fought side by side with the men, while the children and the aged gathered in the cathedrals to supplicate Heaven for protection. No city in the land had better cause to rejoice over peace and the invader's expulsion than Beauvais. And nowhere did Flamboyant Gothic take on nobler expression than in the stately transept now added to the cathedral, a masterpiece worthy to be joined to the giant choir. On its north front worked Martin Chambiges, who gave to Troyes and Sens their admirable façades. Over-ornamentation was a pitfall for the late-Gothic masters, but not for Chambiges, who kept Beauvais' strong lines of construction unobliterated by lavish detail.
