Some four or five cathedrals have stood, in turn, on the same site which was close by the Gallo-Roman city walls. For the early Christians were despised as pariahs, and allowed to build only on the outskirts of cities, until the edict of Constantine permitted them to exercise their religion with honor. All over France churches are to be found abutting on the ancient ramparts of towns. Of the early cathedrals of Bourges only the core of the present crypt remains. From the Romanesque edifice immediately preceding the present cathedral come its XII-century side portals. There are strong analogies between the ground-plan of St. Étienne of Bourges and that of Notre Dame of Paris, especially if one recalls that the cathedral of Paris, as first designed, possessed no transept. Probably the plans of both were made at the same time, but the work in the capital of the royal demesne started immediately in 1163; hence it retained the galleries over the side aisles--a Romanesque tradition--whereas, at Bourges the actual building began only in the last decade of the XII century, when such tribunes were passing out of vogue. Bourges thereupon undertook to modify its first design, and it tried the startling experiment of making an inner aisle whose height comprised both aisle and tribune. The crypt of Bourges,[133] one of the most spacious in France, was begun by Archbishop Henri de Sully (1184-99), brother of Bishop Eudes who helped build the west façade of Paris Cathedral. When Henri died, the decision was left to his brother in Paris, as to which of three Cistercian abbots should be the succeeding archbishop in Bourges. The nomination fell to St. Guillaume Berruyer (1199-1208) of the house of Nevers, whose counts had built the admirable Romanesque St. Étienne in that city. Guillaume had watched both Paris and Soissons' cathedrals rising; he had been a monk in Pontigny, whose church was the earliest Gothic venture in Burgundy, and he was abbot of Châalis, where the church also was Primary Gothic. This holy Cistercian was loath to leave his cloister, and always wore his white robe and fasted like a genuine son of St. Bernard. In his face shone his purity of soul, and it is said that his manner was merry. Only a saint could have made the ambulatory of Bourges, a place apart from the world's fret, fashioned for meditative prayer, its walls hung with gospel parables of mosaic glass. It is thought that while the new Gothic choir was building, services were held in the Romanesque cathedral, which may have been partly open to the elements, since St. Guillaume caught a chill in it while preaching, from the effects of which he died in 1208. Ten years later, the first ceremony held in the completed choir was for his canonization; without the usual process of investigation the pope declared him a saint.
