More of the stained glass of the Thirteenth Century is preserved at York where, because of the friendship of General Ireton, the town and the Cathedral were spared the worst ravages of the Parliamentarians. As a consequence York still {110} possesses some of the best of its old time windows. It is probable that there is nothing more beautiful or wonderful in its effectiveness than the glass in the Five Sisters window at York. This is only an ordinary lancet window of five compartments--hence the name--in the west front of the Cathedral. There are no figures on the window, it is only a mass of beautiful greyish green tints which marvelously subdues the western setting sun at the vesper hour and produces the most beautiful effects in the interior of the Cathedral. Here if anywhere one can realize the meaning of the expression dim religious light. In recent years, however, it has become the custom for so many people to rave over the Five Sisters that we are spared the necessity of more than mentioning it. Its tints far from being injured by time have probably been enriched. There can be no doubt at all, however, of the artistic tastes and esthetic genius of the man who designed it. The other windows of the Cathedral were not unworthy of this triumph of art. How truly the Cathedral was a Technical School can be appreciated from the fact that it was able to inspire such workmen to produce these wondrous effects. Experts in stained glass work have often called attention to the fact that the windows constructed in the Thirteenth Century were not only of greater artistic value but were also more solidly put together. Many of the windows made in the century still maintain their places, in spite of the passage of time, though later windows are sometimes dropping to pieces. It might be thought that this was due to the fact that later stained glass workers were more delicate in the construction of their windows in order not to injure the effect of the stained glass. To some extent this is true, but the stained glass workers of the Thirteenth Century preserve the effectiveness of their artistic pictures in glass, though making the frame work very substantial. This is only another example of their ability to combine the useful with the beautiful so characteristic of the century, stamping practically every phase of its accomplishment and making their work more admirable because its usefulness does not suffer on account of any strained efforts after supposed beauties. Though it is somewhat out of place here we cannot refrain {111} from pointing out the educational value of this stained glass work.
