Since we are told that in this hoarding there were three glass windows, it seems reasonable to suppose that the other windows were glazed too. Now since both the windows in the north choir aisle and, when in its original position, the Methuselah on Plate III. were well to the westward of the point at which the hoarding was erected, I have no doubt that they were in position by this date, in which opinion I am confirmed by the character of the glass itself. That in the Trinity Chapel to the east of the hoarding would naturally be later.
The same arrangement seems to have been followed at Canterbury as elsewhere of having large figures in the clerestory and small medallions in the lower windows.
The Methuselah, which seems to have formed one of a series of Patriarchs,--of which three others remain, which filled the windows in the clerestory of the choir,--is a particularly dignified figure, and it is noticeable that the throne he is seated on is of somewhat the same type as that of Notre Dame de la Belle Verrière at Chartres. As in all windows of this date, the flesh is executed in glass of a brownish-pink colour instead of white, which later on became the rule.
This illustration shows very well the early method of painting. Where possible, as in the rich blue of the background, the glass is left quite clear. The folds of the drapery and the features are drawn in sure and vigorous line work. Diaper is used very sparingly, only when it is necessary to "keep back" and subdue a piece of glass, as in the case of the green cushion to the throne and the border of the tunic. If you can imagine the glass with these pieces left clear or with any other piece diapered, you will see how unerring has been the artist's judgment.[7]
The letters of the inscription are scratched out of a dark ground of enamel. This is the invariable method used in early glass, which indeed is always (except in grisaille, of which more later) conceived as a light design on a dark ground. In the fifteenth century the reverse was the case, and then we get inscriptions in dark lettering on a light ground.
The arched form of the top of the background shows how it once fitted a clerestory light, though doubtless with a border, and the space above has been filled with scroll work of, I think, the same date, which may have come from some of the medallion windows in the choir aisles.
