The "masters of the living stone" who built Rheims Cathedral are known to us to-day. Their names were commemorated in a labyrinth that once formed part of the nave's pavement, a drawing of which has been unearthed by M. Louis Demaison. The obliterated figure in the middle of the labyrinth no doubt represented the bishop who laid the foundation stone. He was Albéric de Humbert, formerly archdeacon of Notre Dame at Paris while the bishops Maurice and Eudes de Sully were raising that cathedral. Builder and crusader, Albéric was a true product of his age. He marched into Languedoc, in 1208, to chastise the Albigensian heretics; he attended Innocent III's great Council of the Lateran in 1214, and when he ventured again to the East to take part in the crusade of Jean de Brienne, he was captured by Saracens and ransomed by the Spanish knights of Calatrava. He died on the return journey, 1218. For a man of such energy, it could have been with slight regret that he witnessed, in May, 1210, the destruction by fire of the decrepit church he had inherited, one of whose builders had been Archbishop Hincmar in the IX century. That early cathedral of Rheims had been redressed with a façade by Archbishop Sampson, a friend of Abbot Suger's, and among the prelates who attended the memorable dedication of St. Denis. His Primary Gothic work, wiped out in the conflagration of 1210, was a loss indeed for art. Bishop Albéric de Humbert set vigorously to work, and within a year of the fire had laid the corner stone of the present cathedral (1211). By 1241 services were held in the finished choir. An archbishop of the Dreux line (1227-40) gave windows to the upper apse, and although he and the townsfolk were at bitter odds, the building of the great church by both prelate and people went on unabated. The imperious Henri de Dreux, like Pierre Mauclerc, the donor of Chartres' south rose, was a grandson of that brother of King Louis VII who built the beautiful church of St. Yved at Braine on the highway between Rheims and Soissons. While the cathedral of Rheims was building, another of its archbishops was a Joinville, and in 1270 its sixtieth ruler died on St. Louis' last crusade. The plan of the cathedral was made by Jean d'Orbais, who had watched the erection of the abbatial (1180) in his native town of Orbais,[115] a church modeled on the choir of St. Remi which the celebrated schoolman Pierre de Celle had built from 1170 to 1180. Thus Orbais is the intermediary between the big abbey church of Rheims and Rheims Cathedral.
