150. Fairford.
The canopy extending across a broad window ([page 200]) may be so schemed that there is obvious recognition of the lights into which it is divided, or it may sprawl across the window space with as little regard to intervening mullions as possible. There is now, in short, full scope for the fancy of the artist, were he never so fanciful; and it would be a hopeless task to try and catalogue the lines on which the design of a large window might now be set out.
We do not in the fifteenth century arrive yet at the most remarkable achievements in glass painting. But you have only to compare such pictures as those on [pages 194], [196], with that on [page 127] to see what a complete revolution has come over the spirit of design. It is not only that the draughtsman has learnt to draw, and the painter to paint; they work on quite a different system. It was explained ([page 44]) how in early days the glazier conceived his design as mosaic, how he first thought it out in lead lines, and only relied on paint to help him out in details which glazing could not give him. Now, it is easy to see that the painter begins at the other end. He thinks out his picture as a painting, and relies upon glazing only for the colour which he cannot get without it.
In the beginning, it was said, the glazier might often have fixed his lead lines, and trusted to his ingenuity to fill them in with painted detail. Now, it would seem, the painter might almost have sketched his picture, and then bethought him how to glaze it. But that is not yet really so. He did not even conceive his design as a picture and then translate it into glass. His work runs so smoothly it cannot be translation. The ingenuity with which he leads up little bits of colour in the midst of white, is no mere feat of engineering; it is spontaneous. It is clear that he had the thought of glazing in his mind all along—that he designed for it, in fact. The difference between the thirteenth century and the fifteenth century designer is, that one thinks first of glazing, is primarily a glazier, the other thinks first of painting, is primarily a painter.
