No one has better summed up the amplitude of this inspired church than M. Georges Durand, its latest historian, whose monograph is a model: “A vast space inundated with air and light has here been covered by stone vaults, as light and solid as possible; those vaults have been raised to a height never before attained; no longer any walls; the solidity of the edifice is assured by a play of pushes and resistances; flying buttresses exactly meeting the necessary spot to counterbut the great vault; the system of equilibrium perfectly known, and applied with a rigor and audacity unbelievable; the least possible sharpness given to transverse arches; the collaterals raised to a great height—all contribute to give this interior its expression of immensity.”

Amiens is a “triumphal chant.” The “vast space inclosed” produces an impression that is confounding. When first you step inside the western doors of Amiens, you pause in awe. The emotion felt has the efficacy of a prayer.

The edifice is prodigious and appears so; only St. Sophia, Cologne Cathedral, and St. Peter’s at Rome cover larger areas. Now in St. Peter’s each detail was enlarged in proportion to the giant scale chosen; thus, a cherub would have a thigh the size of an elephant’s. The result is that the great church appears less than its real size. The method of the mediæval architect was precisely opposite. He saw no advantage in making his edifice appear smaller than it really was. He observed that no matter how big a tree might grow, its leaves were no larger than those on smaller trees. The mediæval architect took for his scale of measurement the height of man. His doorways were made for man to walk under. In the bases of his piers, in the triforium arches, in the normal size of his sculpted flora and fauna, he recalled to the eye the scale of a man, his chosen échelle: “And he measured the wall thereof ... the measure of a man, which is of an angel.”[125] No matter how large a Gothic church might be, the statues decorating it did not increase in scale. To those who prefer a cathedral of the north there will always seem to be a touch of the artificial, of the tour de force in St. Peter’s.

The name of the master mind who designed the cathedral of Picardy was Robert de Lusarches, recorded in a labyrinth formerly in the nave’s pavement, as were his two successors, Thomas de Cormont and his son Renaud. The occasion for a new structure was the fire of 1218 which partly destroyed the Romanesque cathedral. As its old choir was preserved sufficiently to serve for a while longer, the new cathedral was begun by the nave, not the usual procedure. The nave rose in one supreme effort; from start to finish its plan never deviated. It has been taken as the typical masterpiece. “The façade of Paris, the tower of Chartres, the sculpture of Rheims, the nave of Amiens” is a popular summing up.

By 1236 the nave of Amiens was finished, whereupon the Romanesque choir was replaced by a Gothic one whose plan had been drawn by Robert de Lusarches at the same time with that of the nave. His feeling for proportion was unfaltering; the relation between every part of his church is perfect. The interior elevation in three vertical stories was to become classic—a pier arcade—which is one-third of the entire height, and of the remaining upper wall a clearstory which occupies two-thirds and a triforium one-third. The church is three times as wide as the side aisle is high, and height and span correlate with length. Subtlety of calculation is seen everywhere. The perspective view became a kind of classic type. As you gaze down the church toward the curving east wall which closes the vista, you see beneath the pier arcades of the sanctum sanctorum the windows of the apse chapels behind; they appear to fill the apertures symmetrically, whereas at Beauvais, where the side aisle is exceedingly high, the windows of the chapels rise to merely half the height of the pier arches. The cathedrals of Tours and Clermont followed the more satisfactory arrangement of Amiens.

In the last days of Gothic architecture the dislike of the horizontal line was to be carried to such an extent that even the capitals, which the custom of all nations had approved for three thousand years, were eliminated. At Amiens a sane balance was kept. Under its triforium runs a deeply carved band of foliage broken only at the triumphal arches of the transept-crossing. Only there does the ascending line rise unobstructed from pavement to vault. And yet no church ever soared more confidently. The very hall-mark of genius is Amiens’ strong horizontal leaf garland—just the needed touch to give variety to regularity as grandiose as this. In the nave the frieze was cut before the posing of the stones, but in the choir the sculpture was done in situ.

The fenestration of this cathedral of St. Louis’ reign shows the national art in its prime. The glazed triforium is a kind of pedestal for the clearstory, with which it is bound in a single composition by means of continuous mullions. The original glass was of the Sainte-Chapelle type, made by the Paris school which led in the second half of the XIII century, and were it still in existence the interior of Amiens would be a gorgeous sight. Only vestiges have survived; in some of the choir chapels are patchwork panels of ancient fragments. No one denies that the light enters this cathedral too profusely for the mystic seclusion beloved of the soul.

The prelate who laid the foundation stone of Amiens in 1220 was Evrard de Fouilloy, cousin of that archbishop of the great house of Joinville who was a builder at Rheims. Intimate with Innocent III, connoisseur in notable men, the bishop of Amiens was one of the many building prelates who attended the Lateran Council whose séances must often have appeared like an Amis des Cathédrales reunion. Bishop Evrard’s splendid bronze tomb, cast at one flow, escaped the smelting pot of the Revolution, and with that of his successor, Geoffrey d’Eu, who chanted the first Mass in his cathedral in 1236, the year of his death, is now placed under the pier arcades of the nave. “Here lies Evrard,” runs the inscription, “a man compassionate to the afflicted, the widows’ protector, the orphans’ guardian, who fed the people, who laid the foundations of this structure, to whose care the city was given.” The hand of the bishop is raised in a grave gesture of power. The image of Geoffrey d’Eu is less personal. “Bright-shining man of Eu,” runs his epitaph, “by whom the throne of Amiens rose into immensity.” The saintly bishop used to encourage even the beggars to give their penny toward raising the new house of God.

By 1245 bells were placed in the western towers; then came a lull in the work, from 1247 to 1257, for the bishop had accompanied St. Louis to the holy wars. Louis IX was in Amiens on several occasions and his Sainte-Chapelle at Paris proved his admiration for the classic church. As the XIII century closed, a chapel was added to Amiens by her bishop, the learned Guillaume de Mâcon, a personal friend of St. Louis, and present at his death in Tunis, 1270. The son and successor of Louis IX sent Guillaume to Rome to solicit his father’s canonization. During the XIV century other side chapels were added, and in the one erected by Bishop La Grange, from 1373 to 1375, appeared for the first time in France some of the characteristics of Flamboyant Gothic—the flame tracery and ramified vaulting. As early as 1270, however, Amiens had made a sporadic use of supplementary ribs, in the square over the transept-crossing, employing them there, no doubt, in order to break up the immense expanses of infilling.
