The tutelary of Sens Cathedral is St. Stephen, the first martyr. A XII-century statue at the trumeau, or central shaft, of the west door presents him as the beautiful youthful servant of the Lord. Gazing at it one thinks of St. Augustine's words: "The Church would never have had St. Paul but for St. Stephen's prayer." Paul, holding the robes of those who stoned Stephen, heard the martyr pray for his executioners. The trumeau statue of St. Etienne with its parallel feet marks the transition from the column image, such as those at Chartres' western portal, to the XIII-century type of saintly personages at the doors of Rheims and Amiens. It escaped mutilation during the Revolution because some one had the wit to write on the stone tablet in the saint's hand, _The Book of the Law_. The foliage relief on the shaft is exquisite. As the XII century closed the archbishop of Sens was Michel de Corbeil (1194-99), a well-known scholastic writer. Under him and Pierre de Corbeil (d. 1222), his successor and also a learned teacher from the Paris schools, the axis chapel at Sens was rebuilt, and the upper vaulting of choir and nave reconstructed in order to enlarge the windows. As the longitudinal or wall arches were now raised to the level of the keystone, the bombé shape of the vault disappeared; in the chevet the wall ribs show as many as three sets of capitals. The vault sections of the side aisles, however, remained domical, as originally built. Two other distinguished brothers, men of great lineage and intellectual attainment, ruled the see of Sens during many years, Gautier de Cornut from 1222 to 1241 and Gilles de Cornut, who died in 1254; and they had a brother who busied himself with the new cathedral at Beauvais. Gautier de Cornut, who while doctor of law in Paris University served as chaplain to Philippe-Auguste and Louis VIII, was the envoy sent in 1234 to fetch Marguerite of Provence to be married to Louis IX in Sens Cathedral, the king then being in his twentieth year. The young princess of the art-loving Midi came north accompanied by a troop of minstrels. Again in 1239 St. Louis returned to Sens for the Crown of Thorns, on its transit from Venice to Paris, and he walked out some miles from the city to meet it. Barefooted, he and his brother, Robert of Artois, bore back the previous relics to the cathedral, through streets hung with tapestries and lighted by candles. The relic rested in St. Étienne's church all night and then in a solemn, eight-day procession was carried to Paris. The king had the archbishop write the formal account of it all. Gautier de Cornut erected the synodal hall which touches the cathedral's façade, and his own statue and that of the young king decorated its buttresses. The best civic monument of St. Louis' reign many think it to be, and as perfect in its own way as the hospital hall at Ourscamp, its contemporary.
