The third window, that on the north, is filled with a "Tree of Jesse."
The subjects of stained-glass windows in this First Period were chosen with one object—the exposition of the Christian Doctrine, and of this the human descent of Christ was an essential part. Accordingly, at all periods in the history of mediæval stained glass we find windows devoted to the representation of "the Tree of Jesse."
The arrangement is always the same as in this window at Chartres. The figure of Jesse lies recumbent at the foot of the window, and from his loins rises the "Tree"—a mass of branching scroll work with conventional foliage, spreading over the whole window, carrying on its branches David and other human ancestors of Christ, and culminating in the Virgin and Christ Himself at the top of the window. On either side are ranged the Prophets who foretold His coming, and the whole, surrounded by a rich border, forms, at Chartres, a mass of jewelled colour some 9 feet wide and 25 feet high.
This window and the one of which a part, identical in design, remains at St. Denis, are the oldest examples I know of a Jesse tree in stained glass, and whether or not they were the first to be made, their design formed a model for others for long after.
La Belle Verrière.
The remainder of the windows in the Cathedral, including the western rose, are of the thirteenth century with one exception—the one in the south choir aisle, which contains the great figure of the Virgin known as "Notre Dame de la Belle Verrière": the only window, as far as I know, to which in former times people knelt by hundreds in adoration, and before which they still occasionally burn a candle.
The Virgin with the Child on her knee sits enthroned in the upper part of the window, and surrounded by angels, on a much smaller scale, incensing and holding candles, while below are medallions illustrating the Marriage at Cana and the Temptation. The angels and the medallions are of the thirteenth century, but the figures of the Virgin and Child with their background are almost certainly of the twelfth. Probably the veneration in which they were held caused them to be rescued from the fire,—hurriedly broken out, perhaps, from the surrounding glass,—and then reset in thirteenth century work after the Cathedral was rebuilt.[6] The Virgin is dressed in a robe of pale greyish-blue, of a colour one seldom sees in later work, relieved against a background of deep ruby, set with jewels of a darker blue. The precision of the colour harmony is wonderful, and no drawing I have seen of the window gives, even in outline, the beautiful poise of the head, bent in gracious benediction.
Although I have said that the workers of this school were breaking away from the Byzantine tradition and looking at life with their own eyes, yet it is never possible for men suddenly to produce work wholly independent of tradition, even when they are foolish enough to try; so we find in this case Greek art, through Byzantine, retains enough influence with these men to give to their work a dignity and restraint which is lacking in that of the thirteenth century. This is very noticeable wherever one gets the two in close juxtaposition, as at Chartres and also at Canterbury. There is an impressive severity of design and a feeling for proportion in the figure of the Virgin in La Belle Verrière which one misses in the surrounding work, which, though very beautiful, is by comparison small and fussy in treatment.
St. Denis.
In the meantime, in 1142, while the west front of Chartres Cathedral was still in progress, the great Abbot Suger had finished the construction of his abbey of St. Denis, near Paris. He was a great patron of the arts, as well as a good man and the first statesman of his age, and he seems to have spared no pains in the decoration of the church and especially in the filling of the windows with stained glass. Of this glass, alas! only the merest remnant is left, consisting of several medallions and part of a "Tree of Jesse." They have been collected and placed in the chapels of the apse of the church, embedded in garishly coloured ornament—the work of M. Gérente, acting under the orders of the great and terrible Viollet-le-Duc—which effectually prevents one taking any pleasure in their beauty. They are, however, very interesting to study. Whether or not they were done before or after the three windows at Chartres it is, I think, impossible to say for certain. The history of the two buildings shows that they must have been done within a few years of each other (two of those at St. Denis contain figures of Suger as donor, and he died in 1152), and they are certainly the work of the same school. The Jesse tree in particular is either a copy, or the original, on a smaller scale, of the one at Chartres, being almost identical in design.
