It cannot but be regretted that the two large windows east and west of #The Lady-Chapel# are not portions of the building as it stood at first. That to the east, of seven lights, is known to have been inserted by Bishop Barnet, who died in 1373. The authority for this is the sacrist's roll for that year. The item is given in Dean Stubbs' "Historical Memorials," p. 147. The bishop's executors paid L20 "for making a certain window in the lady-chapel near the high altar in the preceding year." The west window, of eight lights, is of somewhat later date. Considering that the chapel was finished in 1349, and that there is no reason to doubt that the east and west ends were adorned with fine windows of the same character as those in the sides, it seems extraordinary that within twenty-five years it should have been thought worth while to alter the eastern end. Was the alteration made in connection with the insertion of a grander reredos than had been at first provided? This seems possible, as may be judged from the following observations of the present Dean: "It is evident from indications supplied by the masonry of the central light of the east window, the mullions of which are of unusual solidity, that the Reredos and East window were originally combined in some structure, of which the chief object was the large figure of S. Mary, often mentioned in the Rolls of the Custos Capellae, and which must have occupied a canopied niche, blocking up the whole of the middle light from sill to transom."[10] The design of the east window is inelegant, the transom is heavy, and the tracery in the large circle at the top spoils the effect of the window as a whole. [Illustration: THE CHOIR AND LADY-CHAPEL FROM THE NORTH-EAST.] The west window, except for the central portion at the top and the heavy mullions, is just like two of the side windows placed side by side. But here again the vertical lines in the upper part harmonise ill with the rest. There are some good niches at the west end above the window, but there are no figures in them; and there are shallow arches on the surface of the wall, on each side of the window as well as beneath it. Above most of the niches are shields with heraldic bearings, twelve in all. Among these are the coats of Edward the Confessor, the See of Ely, Bishops Hotham, Montacute, Fordham, and perhaps Barnet.[11] One shield has a cross, and one a lion between three helmets. The arms of the monastery--three keys (said to have been adopted from Bishop Ethelwold of Winchester)--occur four times, in three cases with initials beneath. These initials are: A. W., which may certainly be assigned to Alan de Walsingham; J. C.; and C. W. S. From the occurrence of Bishop Fordham's arms we may conclude that this west end was reconstructed, or at least that its reconstruction was completed, in his time (1388-1425). In some of the lower niches are memorial tablets.
