There was another reason for the adoption of a narrower border. Not only were windows narrower now, but their arched heads were cusped, which made it exceedingly difficult to carry any but the narrowest possible border round them satisfactorily. It will be seen how awkwardly the border fits (or does not fit) the window head on [page 155]. Even the simplest border had to be very much distorted in order to make it follow the line of the masonry; and, in any case, it gave a very ugly shape within the border, and one again difficult to fill. Already, at the beginning of the fourteenth century, the designer found it convenient to run his border straight up into the cusped head of the light and let the stonework cut it abruptly short; that occurs at Carcassonne. Sometimes, as at Tewkesbury, the inconvenient border is allowed to end just above the springing line of the arch, against a pinnacle of the canopy, beyond which point there is only a line or two of white or colour, by way of frame or finish to the background. An unusual but quite satisfactory way of getting over the difficulty of carrying the border round the window head is, to accept the springing line of the arch as the end of the central design, and to make the foliated border spread and fill the entire window head above. Some quarry lights in the triforium at Evreux are effectively treated in that manner.

Types of ordinary Decorated borders, English, French, and German, are shown in this and the preceding chapter. The leafage springs from one side or the other or from a central stem, or from either side of a waving stem, or from two stems intertwined ([page 158]). Sometimes the ground on one side is of a different colour from that on the other; in any case the glazing is usually simple. One of the leaf borders at Rouen Cathedral includes a series of little green birds; another, an oak pattern, is inhabited at intervals by squirrels and wild men of the woods. Rather interesting variations upon the ordinary type of border are given on this and the preceding pages. The broader one [above] is of distinctly unusual character, inasmuch as it has no background except the painting out, and the colour of the leafage varies quasi-accidentally.

The use of the rosette borders on [pages 171], [172] is sufficiently accounted for by the desire to get contrast to the foliated filling, but it occurs at all periods more or less. So does the "block border"; but for all that it is almost as characteristic of Decorated work as the leaf border. It is seen in its simplest form on [page 144]. On [page 389] it is associated with foliage and rosettes. A typical form of it is where the blocks are charged with heraldic devices, which may serve to indicate the date, or to confuse one. In the design from Evreux on [page 160] there occur, for example, the Fleurs-de-Lys of France alternating with the Castle of Castille. These particular charges occur frequently in the windows of the S. Chapelle at Paris, and in the lights from that source now in the South Kensington Museum; and they go perhaps to show that Blanche of Castille (who married Louis VIII.) gave them to the chapel, or that they were in her memory. She died in 1252. It is most improbable that the Evreux glass should belong to so early a date as that. Were it so, the occurrence of this kind of thing in such early work would only go to show that heraldic devices are as old as heraldry, and that when the glazier had a narrow light to fill he treated it as a narrow light, with a border in proportion to its width: he certainly did that at the S. Chapelle. The fact remains that this particular form of “block” border marks, as a rule, the approach of the fourteenth century.
