THE LADY CHAPEL was finished in 1326, before the presbytery was added to the present choir, and thus it belongs to the middle of the Decorated period. In plan it is octagonal, the three western sides consisting of the three arches by which it is opened to the rest of the church. It could, in fact, stand perfectly well as a detached building like the Lady Chapel at Gloucester, and doubtless it did so stand while the presbytery was a-building; but its connection with the church itself allows its apsidal west end to be cunningly combined with the beautiful pillars which support the vault of the ambulatory. The arrangement by which these three western sides project into the ambulatory is more easy to see than to describe; from the west side of the piers which support them spring the vaulting ribs of the retro-choir, while on the east side of the piers the shafts rise much higher up to carry the loftier vault of the Lady Chapel. As the chapel is not a perfect octagon like the chapter-house, but is elongated from east to west, this vault was difficult to manage, and its lines are somewhat distorted in consequence. The vault springs from triple shafts between fine traceried windows of five lights, and its ribs meet in a boss containing a beautiful figure of our Lord seated on a throne with outstretched arms; the colour and gilding are well restored. Professor Willis said that "the polygonal Lady Chapel and the vaulted work which connects it with the presbytery is a most original and unique piece of architecture, of pure and beautiful design." As to the first part of this sentence there can be no difference of opinion, and all will agree as to the fineness of the general effect of the chapel; yet there may well be two opinions as to the purity of the work. I confess that the following criticism (_Builder_, Aug. 1862) from a lecture of Mr E.W. Godwin seems to me to be not entirely without justification:--"With the single exception of the way in which the vaulting is managed, I look upon this Lady Chapel as no better than the other work of the same date. There is a weakness about the constant recurrence of the same form in the tracery of the windows; the lines of the vault are, in some cases, clumsy to a degree; and the capitals have lost their constructional character altogether. The growth and vitality, the change and joyfulness, so visible in the earlier caps, especially those with figures, are no longer to be seen. Leaves are now stuck on; or, at the best, wreathed round the bell of the capital; and so the _function_ of the capital--the upbearing principle--is lost." So much for its defects. The peculiar excellence of the chapel is that it gives that apsidal ending to the church which adds so much to its beauty both within and without, and yet does not interfere with the square end of the presbytery.
