Tragic the fate of its sister abbatial, St. Remi, in martyred Rheims. That grand ancestral church lies well-nigh mortally wounded on the field of honor. It stood up above the city as prominently as the cathedral itself, and has been mercilessly wrecked. The vaulting has fallen, and great rents have been torn in the walls of the precious Primary Gothic choir. A recent traveler found that its devastated nave recalled gaunt Jumièges. Some ten years after the reconstruction of Notre Dame at Châlons, the monks of St. Remi began to make over their abbey church under the inspiration of Abbot Pierre de Celle, of the same lineage as the heiress of Braine who, with her husband, a brother of Louis VII, built the church of St. Yved. While John of Salisbury was a young student in France, Pierre de Celle entered into a friendship with him which continued to deepen till their death, both of them being men of the highest culture, strong literary abilities, and solid character. Pierre de Celle succeeded the English scholar as bishop of Chartres in 1181; _summi et incomparabilis viri_, so his epitaph sums him up. It was this distinguished churchman who built, about 1170, the superb choir of St. Remi, and who remodeled as Gothic the ancient Romanesque nave. The choir had five radiating chapels, each of which opened on the ambulatory in the beautiful Champagne way, by slender columns bearing stilted arches. As tribunes were built over the aisles, the wall elevation was in four stories, and below two of them ran friezes of sculptured foliage. As if the architect felt that he had thus over-accentuated the horizontal line, he bound his triforium and clearstory into one composition by continuous moldings, a precocious first step toward the glazed triforia of Rayonnant Gothic. Originally no flying buttresses braced this early-Gothic choir; those that were added, about 1180, are probably the first ever made. Nothing could better show the swift development of Gothic structure than to compare the plain old flying buttresses of St. Remi with the luxuriant counterbutting members of Rheims Cathedral built fifty years later. Between St. Remi's choir and the hemicycle transept of Soissons Cathedral there is such similitude of profile, detail, and plan that it is thought the same architect designed both. The able Pierre de Celle built the two westernmost bays of St. Remi's nave, and opened the tribune on the middle vessel with Gothic arches. He also built the west façade, which to-day is ancient only in its lower stories, as it was reconstructed in 1840. The north tower was re-done in the XII century; the south one is of the XI century, Abbot Herimar's time.
