These windows show a progressive increase in the use of white for flesh colour instead of the brownish pink formerly used. At first, white is used only for women's faces, and then for those of saints of both sexes, brown-pink continuing to be used for other people till quite the middle of the century or later. Stain is not used on the hair at first, but sometimes a thin brown matt of enamel is laid all over the hair which at a distance has almost the effect of stain. [Sidenote: The sixth window in the north aisle.] The sixth window on the north side is, I think, a good many years later in date than these ten windows we have been considering, and is much less beautiful. A canopy and border from it are shown in Plate XVIII.a on the right. Although the same general arrangement is adhered to as in the other windows, the treatment is much coarser; the crockets of the canopies are big, heavy, and ugly, of a brownish-yellow pot-metal, but at the same time stain is freely, indeed lavishly, used, not only in the canopies and borders but, for the first time in the Cathedral, in the quarries of the grisaille as well. The borders of heraldry or little figures have given way to running patterns of natural foliage of the more common fourteenth century type. There are four different patterns of these borders in the window, so that some probably came from another window of the same date, perhaps in the now empty seventh window. [Sidenote: The west windows.] Later still are the three west windows and the sixth in the south aisle which mark a further stage in development. Here we have at last a definite date to help us, for the contract with the glazier, one Robert, is still in existence and is dated 1338, so we may assume the windows were finished about 1340. It is difficult to judge these windows fairly, for they were subjected to a most drastic restoration in the eighteenth century, and the great central one is further disfigured by protective quarry glazing on the outside, which reduces it to a dirty brown. I do not think, however, that they can ever have been, comparatively speaking, very good, and I am inclined to look upon them as perhaps the poorest work of the Middle Ages. Plate XIX. shows one light of the northernmost of the three, that at the west end of the north aisle. It will be seen that the canopy has now grown to an absurd height and fills the whole light, and neither in its proportions nor in its details is it very graceful. The border is now growing narrower and narrower, and is eventually doomed to disappear altogether. The crockets of the gable are the only yellow pot-metal used, silver stain being used everywhere else, and not very artistically, though how far this is due to the restorer it is difficult to say.
