In structural technique the fenestration of Chartres was a stride forward, and both the cathedrals of Paris and Soissons learned immediately from its clearstory arrangement—the first attempt to fill with colored glass the entire space between the active wall shafts. “In certain parts of the cathedral of Chartres,” says M. Mâle, “is a magnificent amplitude, a superabundance of power. Each of the nave’s windows is surmounted by an immense rose as wide as the bay, a conception as proud as ever an architect realized. It is one of those flashes of genius such as came to Michael Angelo. Those great orbs of light, those wheels of fire that dart sparkling rays are one of the beauties of the cathedral.”[111]
Notre Dame has preserved over two hundred of the ancient, imaged windows. The oldest and the best are three large lancets under the western rose which, like the Royal Portal beneath them, are the work of Suger’s craftsmen who came here from St. Denis. One of these noted windows relates the childhood of Christ, another His Passion and Resurrection, and the third is a tree of Jesse, similar to one in St. Denis.[112] The iron bars supporting the sheet of glass do not conform to the outline of the medallions, hence it is somewhat more difficult to decipher the scenes than in XIII-century work. None the less, these, the oldest windows of the cathedral, are the peer of any colored glass ever made, because of their inherent genius for decorative effect and their conscientious workmanship. Many a pen has tried—in vain—to describe the marvelous deep blue which blends together the other colors—the streaky ruby, the emerald green, the sea-green white, the brownish purple and pink, the yellow pot metal.
Even after the opening of the XIII century the St. Denis school exerted influence, as is shown by the Charlemagne-Roland windows in Chartres’ ambulatory, whose outline was taken from a crusader window of Suger’s abbey. The majority of Chartres’ windows belong to the early XIII century, when the city was mistress of the vitrine art and supplied the cathedrals of Bourges, Rouen, Sens, Laon, Auxerre, Tours, Le Mans, Poitiers, and even Canterbury. In the nave’s north aisle, the St. Eustace window (the third) is held to be of faultless artistry. The large lancets which light the aisles scintillate as with precious jewels. Only some five or six have floral scrolls filling the spaces between the medallions and the deep border that surrounds each window; in France a geometric pattern for such interstices was more frequent.
At the base of each window is what is called its signature—a medallion which usually represents the avocation of the donors, whether kings, knights, priests, butchers, shoemakers, furriers, or water carriers. Thus below the Charlemagne-Roland windows tradesmen display rich fur mantles, and we know that the pelletiers were the donors. Splendid were the gifts of the old artisan guilds. The tanners presented an apse-chapel window in honor of St. Thomas Becket, the vintners one that related the story of Noe, planter of vines. An overpowering sensation it must have been for those mediæval workmen to worship beneath the vaults they themselves had helped to build, under the windows they had contributed. Kings and knights were their fellow donors, but in the cathedrals of France the gifts of the lowly were the most plentiful, a Christian quality which endured till the XVI-century disunion.
To Chartres St. Louis gave a window in honor of St. Denis, patron of his kingdom. The splendid red northern rose, “The Rose of France,” is a glorification of Our Lady. The donjons of Castile adorn it in honor of the queen regent. Directly opposite is the big south rose presented by Blanche’s enemy, Pierre Mauclerc, who tried to kidnap Louis IX from his mother, but who was to die fighting the infidels under his cousin the king, as did Pierre de Courtenay, another donor of a window at Chartres. Pierre de Dreux, it is said, began the porch before the southern entrance to commemorate his marriage with the heiress of Brittany, a granddaughter of Henry II, Plantagenet. Like every door of this church of the resplendent entranceways, it is a mass of sculpture. Mauclerc was grandson of the builder of St. Yved at Braine, and brother of Archbishop Henri de Dreux, who donated windows to his cathedral at Rheims. Below the Dreux rose at Chartres, four of the Prophets are borne on the shoulders of the four Evangelists, for never could those generations, enamored of symmetry, resist the opportunity to weave together the Old and New Testaments.
A first cousin of St. Louis, Ferdinand III, the saint-conqueror of Seville and Cordova, donated to Chartres a window commemorating the patron of Spain. Three times was St. James honored here, so popular was the Santiago Compostela pilgrimage. St. Martin and St. Nicolas of Bari are also commemorated, the former some seven times, for it pleased the voyagers to noted shrines to record their travels. By pilgrimages French art and song spread in Italy and Spain.
Single monumental figures of prophet or saint were used in the clearstory windows instead of small medallions, which would be indistinct when viewed at such a height. Although most of the windows in the cathedral belong to the XIII century, the XV century is represented in the Vendôme chapel, begun in 1417 by Louis de Bourbon, an ancestor of Henry IV. Much white was then employed for the better lighting of the church, and the straight saddle-bars of Suger’s time were again made use of.
No attempt was made for perspective in the earlier glass, which was treated like a translucent mosaic: relief was obtained by the skilled juxtaposition of tones. The old workers had taught themselves many of the secrets of optics. They knew that designs on a background of blue—an expansive color—should be larger than those on red—an absorbent. They knew that blue was a sedative, that red excited the vision, and that yellow stopped contours, hence it was to be employed in borders.
It is not of technique that one thinks when standing face to face with the windows of Chartres. “Create in me a new heart, O God!” one murmurs when gazing at them. When at noon the sun renders the colors dazzling and bewildering, the cathedral seems to be chanting “Sanctus! Sanctus! Sanctus!” with the seraphim proclaiming that the whole earth is full of the glory of the Lord. Live coals from heaven’s high altar are the windows of Chartres, then, cleansing us of our iniquities; and seeing with our eyes we see, and hearing with our ears we hear, and understanding with our heart we comprehend the vision and are converted and healed.
When evening blots out the rest of the church, and in luminous obscurity the windows hang ethereally in space, they are psalms of intercession and penitence. To gaze at such windows is to pray, think the Levites who serve in this temple. At sunset it is no unusual sight to see a young student of theology seated with his back to the choir, his forgotten breviary open on his knee, gazing spellbound at the western lancets, in his face a rapt reverence, indicating that his soul is in prayer. Each evening the windows of Abbot Suger’s craftsmen hymn the suave and lovely Te Lucis ante which ushers in night’s purity. A mediæval cathedral was designed for the Real Presence, and without that soul of all ritual it stands bereft. Windows such as Chartres’ proclaim the miracle of the Tabernacle as symbolically as do those pillars of humanity sculptured by the northern doors, Melchisedek and Peter, types of the Christ, each holding a chalice, or as do the transept’s outspread arms that recall the sacrifice on Calvary, renewed daily in the sacrifice of the Mass.
