It is impossible, however, in the limits of this work to describe even all the important windows of this period, and I have taken those I have already described as typical of their time and as together showing the progress of the development of the art. [Illustration: PLATE XX ST. STEPHEN, FROM SOUTH AISLE OF NAVE, YORK MINSTER Fourteenth Century] [Sidenote: The Sainte Chapelle.] The most complete example of the work of the latter part of the thirteenth century is the Sainte Chapelle in Paris, built by St. Louis to contain the Crown of Thorns, which he had purchased with other relics from the Emperor of Constantinople, who was then in need of ready money. The Chapel was consecrated in 1248, but although some at least of the windows are said to have been prepared beforehand and to have been in their place on that occasion, yet the series was certainly not completed till after the death of St. Louis in 1270, as that event is represented in one of them. The glass has unfortunately suffered a good deal from restoration, and it is difficult now to say quite how much beauty it once had, but it must be confessed that at present it gives one none of the joy and wonder of Chartres. Yet the very design of the Chapel shows the importance which the art had now attained, for the building is constructed entirely with a view to being filled with stained glass, being in fact a mere glass-house with no wall spaces at all. If the colour effect may be judged of from the specimens of the original glass now in South Kensington Museum, the place must have been a wondrous Aladdin's cave of jewels, but at the same time it may be doubted whether the arrangement was a wise one. The windows at Chartres gain immensely by the spaces of gloom between them, whereas here the eye gets no rest. In detail, apart from colour, the work shows a certain falling off. The artist seems to have been cramped by the necessity of adapting the medallion window to such narrow lights. One misses the fine broad border which does so much to "pull together" the earlier medallion windows. The borders at the Sainte Chapelle are narrow and uninteresting, and even so the medallions have sometimes to overlap them. [Sidenote: Work of Clement of Chartres at Rouen.]
