Windows: A Book About Stained & Painted Glass. Lewis F. Day

it followed, as a matter of course, from the very estimation in which he held his material, that he did not think of obscuring it by paint—defiling it, as he would have held. It is not so much that he would have been ashamed to depend on the painter to put his colour right, as that the thought of such a thing never entered his mind; he was a glazier. It was the painter first thought of that, and his time had not yet come.

      Possibly it may have occurred to the reader, apropos of the diagram on page 10, in which it was shown how far the glazier could go towards the production of a map in glass, that that was not far. Certainly he does not go very far towards making a chart of any geographical value, but he does go a long way towards making a window; for the first and foremost qualities in coloured glass are colour and translucency—and for translucent colour the glazier, after the glass-maker, is alone responsible. It is in some respects very much to be deplored that the Gothic craftsman so early took to the use of supplementary painting, which in the end diverted his attention from a possible development of his craft in a direction not only natural to it but big with possibilities never to this day realised.

10. Glazing in Plaster. South Kensington Museum.

      Of richly jewelled Gothic glass all innocent of paint, no single window remains to us; but there are fairly numerous examples extant of pattern windows glazed in white glass, whether in obedience to the Cistercian rule which forbade colour, or with a view to letting light into the churches—and it is to churches, prevalent as domestic glass may once have been, we must now go for our Gothic windows.

      Some of this white pattern work is ascribed to a period almost as early as that of any glass we know; but it is almost impossible to speak positively as to the date of anything so extremely simple in its execution; in which there is no technique of painting to tell tales; and which, when once “storied” windows came into fashion, was probably left to the tender mercies of lesser craftsmen, who may not have disdained to save themselves the trouble of design, and to repeat the old, old patterns.

      The earlier glazier, it was said, painted, figuratively speaking, in glass. It is scarcely a figure of speech to say that he drew in leadwork.

      This mode of draughtsmanship was employed in all strictly mosaic glass; but it is in the white windows (or the pale green windows, which were the nearest he could get to white, and which it is convenient to call white) that this drawing with the leads is most apparent—in patterns, that is to say, in which the design is formed entirely by the leadwork.

11. Plain Glazing, Bonlieu.

      You have only to look at such patterns as Nos. 11 to 17, to see how this was so; they are all designed in outline, and the outline is given in lead. It is perfectly plain there how every separate line the glazier laid down in charcoal upon his bench stood for a strip of lead. And, looking at the glass, we see that it is the lead which makes the pattern. It is no straining of terms to call this designing in the lead. The ingenuity in designing such patterns as those below and opposite, which is very considerable, consists in so scheming them that every lead line shall fulfil alike a constructive and an artistic function; that is to say, that every line in the design shall be necessary to its artistic effect, that there shall be no lead line which is not an outline, no outline which is not a lead.

12. Châlons.

      It is not always that the glazier was so conscientious as this. M. Viollet le Duc pointed out, in the most helpful article in his famous Dictionary of Architecture, under the head of Vitrail, how in the little window from Bonlieu, here illustrated, the mediæval craftsman resorted to a dodge, more ingenious than ingenuous, by which he managed to economise labour. Each separate lead line there does not enclose a separate piece of glass. The lines are all of lead; but some of them are mere dummies, strips of metal, holding nothing, carried across the face of the glass only, and soldered on to the more businesslike leads at each end. The extent of bonâ fide glazing is indicated in the right-hand corner of the drawing. I confess I was inclined at first to think that Viollet le Duc might, in ascribing this glass to the twelfth century, very possibly have dated it too far back; for this is the kind of trick one would more naturally expect from the later and more sophisticated workman; but I have since come upon the same device myself, both at Reims and Châlons, in work certainly as old as the thirteenth century. You see, cutting the glass was the difficulty in those days, and sometimes it was shirked.

       13. Châlons.

      It should be noted that the subterfuge employed at Bonlieu and in the specimens from Châlons, opposite, was not in order to evade any difficulty in glazing—the designs present none—but merely to save trouble. There would have been more occasion for evasion in executing the design from Aix-la-Chapelle (14), where the sharp points of the fleur-de-lys give background shapes difficult for the glazier to cut. It will be noticed that to the left of the panel one of the points joins the necking-piece, which holds the fleur-de-lys together. That is a much more practical piece of glazing than the free point, which presents a difficulty in cutting the background, indicative of the late period to which the glass belongs. The earlier mediæval glazier worked with primitive tools, which kept him perforce within the bounds of simplicity and dignified restraint.

      In white windows, so called, he did not by any means confine himself wholly to the use of what it is convenient to call “white glass.” From a very early date, perhaps from the very first, he would enrich it with some slight amount of colour. Having devised, as it were, a lattice of white lines, as in the left-hand pattern from Salisbury (overleaf), it was a very simple thing to fill here and there a division of his design with a piece of coloured instead of white glass, as in the pattern next to it in order. The third pattern, to the right, shows how he would even introduce a separate jewel of colour, perhaps painted, which had to be connected with the design by leads forming no part of the pattern.

      Colour spots are more ingeniously introduced in the example from Brabourne Church, Kent, (said to be Norman) where the darker tints are ingeniously thrown into the background. But here again, although this is perhaps as early a specimen of glazing as we have in this country, the glazier resorts in his central rosettes to the aid of paint.

      14. Aix-la-Chapelle.

      It will be observed that in the marginal lines which frame this window, and again in the white bands in two out of the three patterns from Salisbury, leads are introduced which have only a constructional use, and rather confuse the design. That they do not absolutely destroy it is due to its marked simplicity, and to the proportion of the narrow bands to the broad spaces. This is yet more clearly marked in the very satisfactory glazing designs from S. Serge at Angers. The fact is, there is a limit to the possibilities of design, such as that from Sens (page 96), in which literally only four leads (viz., those from the points of the central diamond shape) are introduced wholly and solely for strength; and when it comes to windows of any considerable size, such as clerestory windows, to which plain glazing is peculiarly suited, leads which merely strengthen become absolutely necessary. The art of the designer consists in so scheming them that they shall not seriously interfere with the pattern.
