The four great arches rise to the full height of the roof; that to the east, indeed, is higher than the vaulted roof of the choir and presbytery, the intervening space being occupied with tracery of wood-work on painted boards, the Saviour on the Cross being painted in the middle. The wooden vaulting of the octagon springs from capitals on the same level as those of the great arches. The four small arches to the aisles are of course no higher than the roofs of the aisles: above these, on each side, are three figures of apostles, under canopies with crockets. The figures are seated, and each holds an emblem, by which it can be seen for whom the figure is intended. It may be noticed (in the central figure on the south-west side) that S. Paul, not S. Matthias, is put in the place of Iscariot. The hood-moulds of the arches are terminated by heads, of which six are portraits. King Edward III. and Queen Philippa are at the north-east, Bishop Hotham and Prior Crauden at the south-east, Walsingham and his master mason (so it is believed) at the north-west; those to the south-west are mere grotesques. Above the seated figures on each side is a window of four broad lights, filled with stained glass. The eight chief vaulting shafts rise from the ground as slight triple shafts; they support, a little above the spring of the side arches, large corbels, which form bases for exquisitely designed niches, and through these spring more shafts reaching to the vault. On each of the corbels is a boldly carved scene from the career of S. Etheldreda; they commence at the north-west arch. The subjects (two to each arch) are as follows: NORTH-WEST ARCH.--S. Etheldreda's second marriage. Her taking the veil at Coldingham. NORTH-EAST ARCH.--Her staff taking root. Her preservation in the flood at S. Abb's Head. SOUTH-EAST ARCH.--Her installation as Abbess of Ely, Her death and burial (two scenes). SOUTH-WEST ARCH.--One of her miracles. Her translation.
