Two often-quoted ancient records described the surge of religious fervor which raised the western end of Chartres Cathedral. In 1145 the archbishop of Rouen wrote to the bishop of Amiens to relate how the people of his diocese, knights and ladies, townspeople and peasants, went in a spirit of penitence to Chartres, there to help in the new work of Notre Dame. No one could join the pilgrimage who had not confessed, and renounced all enmities and revenges. As the quarries were some miles from the city, it was a heavy task to drag in the big stones. In that same 1145 Abbot Haimon of St. Pierre-sur-Dives in Normandy, wrote to some monks in England to picture the scenes at Chartres: "Whoever heard tell in times past of powerful princes brought up in honors and wealth, of noble men and women bending their proud necks to the harness of carts, and like beasts of burden dragging stones, cement, wood, to build the abode of Christ? And while men of all ranks drag these heavy loads--so great the weight that sometimes a thousand are attached to one wagon--they march in such silence that not a murmur is heard. When they halt by the roadside, only the confessing of sins, and prayer, humbly suppliant, ascend to God. If anyone is so hardened as to refuse to pardon his enemies, he is detached from the cart and refused companionship in that holy company. When they have reached the church they arrange the wagons about it like a spiritual camp, and during the whole night they celebrate the watch by hymns and canticles." It was not long after this wave of enthusiasm that the Portal Royal was begun, probably about 1155, though some have placed those three western doors earlier and some later. As they resembled the doors of St. Denis (now destroyed), they were made, doubtlessly, within ten or fifteen years of Suger's work. By 1175 cracks appeared in the new west foundations, and the three doors were moved forward, stone by stone, and placed on a line with the towers. In their first position, set back between the advancing towers, they had shown to better advantage, but it is to the advance of Chartres' western façade that we owe the preservation of its priceless glass and sculpture.
