Its companion at the east end of the south aisle is also fine in both colour and design. Observe the drawing of the heads in the second window from the east in this aisle. The last one of all is French of about the end of the sixteenth century, and was brought here from Rouen by Lord Carlisle in 1804. Fine as it undeniably is, its rich Renaissance hues do not harmonise with the lower tints of its earlier English neighbours. The examination of these minor possessions of this part of the edifice now leads us up to its crowning glory, the great east window. The nine lofty lights are subdivided into three groups of three each by two mullions thicker than the others. All these mullions are swerved above and then disposed in accordance with the best Perpendicular traditions. Like the large windows of the east transepts there is here a double plane of stonework reaching half-way up the face of the embrasure. At the point where this double stonework stops there is carried across its top a gallery right against the face of the glass. So vast is this great surface (seventy-eight feet by thirty-two feet) that the gallery would escape notice if it were not pointed out. The two hundred panels of figures which here appear depict in the upper half Old Testament scenes from the creation of the world to the death of Absalom; below are scenes from the Book of Revelations, and lowest of all a series of kings and archbishops. The contract for the glazing is dated 1405 and calls for the completion of the work in three years. Even if the rest of its great wealth of windows be disregarded, York Cathedral, by virtue of this vast screen of colour and of the exquisite group of the "Five Sisters," would rank as one of the most notable points of interest in the world for the lover of stained glass.
