The Nave Aisle Windows are smaller than those in the Chapter 
House, consisting of three lights 3 feet wide and 20 feet high, and 
having three quartrefoils in the window head, whilst those of the 
Chapter House have five lights surmounted by two cinquefoils 
and three nine-foiled circles. 
The general design of the glass in both Chapter House and Nave 
is similar, being alternately white diaper and coloured subject 
bands, but in the Nave the subjects are under canopies, whilst the 
Chapter House windows have four rows of coloured subjects in 
medallions. In the Chapter House the window heads are adorned 
with heraldic shields, but in the Nave the shields are placed on 
the white diapered panels, the quatrefoils being occupied by a 
figure or a subject. 
The nave windows have white panels outlined with natural 
foliage, alternating with two rows of coloured subjects. The sub¬ 
jects are under large golden tabernacled canopies set on a rich 
ground of either red or blue, and have a brilliant appearance. 
An inscription crosses the base of the lower subjects. In these 
windows we have the earliest use of yellow stain, which is pro¬ 
duced by applying silver to the glass. Some of the glass was 
damaged in 1840 by the fire which destroyed the nave roof. 
Quite recently, in the north aisle, with one exception, the windows 
have been taken out and re-leaded, and in the south aisle a 
window was restored in 1903.
