“The glass in the choir is almost wholly Perpendicular. As in the nave, it is very fragmentary and disordered. The change in the character of the design will be easily noticed. The Perpendicular glass is not so clear and delicate in colour, and the architectural and other patterns are less pronounced. This glass, regarded simply as decorative, is perhaps superior to that in the nave. “Mr. Winston has pointed out that the earliest Perpendicular glass in the choir is contained in the third window from the east in the south aisle; in the third and fourth windows from the east in the north clerestory; and in the fourth clerestory window from the east on the opposite side. These windows date from the close of the Fourteenth Century. There is also an early Perpendicular Jesse in the third window from the west in the south aisle of the choir. The other windows of the choir aisles east of the small eastern transepts, as well as the glass in the lancet windows on the east side of the great western transepts, appears, he says, to be of the time of Henry IV.; the rest of the glass in the choir is of the reigns of Henry V. and VI., chiefly of the latter. He notices also, that the white glass in the windows is generally less green in tint than usual, and that he has learnt from Mr. Browne that it is all of English manufacture.”--(A. C.-B.) We now come to the smaller transepts situated between the four eastern and four western bays of the choir. They are practically one bay of the choir with the triforium and clerestory removed. At each end are immense windows. Each is 73 feet long by 16 feet wide. Both have been restored; but the glass is original and very splendid. The north window contains scenes from the life of =St.= =William=; the south window depicts the history of =St. Cuthbert=, and is thought to date from about 1437. In it are members of the house of Lancaster. The east end of the choir is almost entirely filled with the great =East Window=. The space behind the altar is sometimes called the =Lady-Chapel=. This occupies four bays. It was built in 1361-1405, and is Perpendicular in style. The Altar of the Virgin stood under the great east window and here also was a chantry founded by the Percys. “The great east window was glazed by John Thornton of Coventry. The terms of the contract for this work, dated 1405, are extant. They provide that Thornton shall ‘portray the said window with his own hands, and the histories, images, and other things to be painted on it.’ It was to be finished within three years. Glass, lead and workmen were to be provided at the expense of the chapter, and Thornton was to receive 4s. a week, £5 a year and £10 at completion for his trouble.
