The general construction of wooden screens is close panelling beneath, on which stands screen-work composed of slender turned balusters or regular wooden mullions, supporting tracery more or less rich with cornices, crestings, &c., and often painted in brilliant colours and gilded.
Specially serious damage was done in the immediate neighbourhood of the chapel, but the finely moulded arches and the magnificent tracery of the east window survived in great part.
Here also was produced the Book of Dimma, consisting of the gospels and accompanied by a brazen shrine, ornamented with silver and tracery, and preserved in the library of Trinity College, Dublin.
The church, however, was almost wholly reconstructed in the Perpendicular period, and is a fine example of that style, the interior gaining in beauty from the scheme of colour-decoration in the choir, while the magnificent stone-vaulted roof with fan tracery, extending throughout the church, excepting the south transept, is unsurpassed.
The development of tracery was hindered both by the material and by the relative insignificance of the windows.
