With such a man as Walsingham on the spot we cannot be wrong in assigning to him the authorship of all the architectural designs that were carried out in his lifetime. It is believed—for the date is not exactly known—that he died in 1364. Besides the lady-chapel and octagon, he must have designed the singularly beautiful bays of the presbytery between the octagon and Northwold's work. The exquisite way in which the main characteristics of the Early English work are adapted to the Decorated style demands our highest admiration. The arrangement of the three western bays on each side is exactly like Northwold's work, while the additional grace and beauty of ornamentation mark the advance in taste that distinguished the Decorated period. Bishop Hotham undertook the whole expense of rebuilding this portion of the cathedral. He did not live to see it completed, as he died in 1337, but he left money for the purpose. The total expense of this rebuilding is given at £2034 12s. 8¼d., while the cost of the octagon and lantern amounted to not very much more—£2406 6s. 11d. Nearly all this latter cost was defrayed by the monastery, little more than £200 having been contributed from external sources. These amounts must be multiplied by twenty, if not twenty-five, to represent the present value. The rebuilding of these three bays in the presbytery involved the rebuilding of the corresponding portions of the aisles.
The domestic buildings were also improved, and some new ones erected by Walsingham. "The Sacrist's Office he almost new built, made several additional apartments in it, and encompassed the whole with a strong wall; in the North-west corner of which he built a square building of stone, and covered it with lead; part of this he appropriated to the use of Goldsmith's work, and for other purposes relative to his Office; another Building taken notice of as built by him, was contiguous to the Infirmary; it was of stone, covered with lead, and had convenient offices under it, chiefly intended for the use of the Custos of the Infirmary. In his time also, Bells[13] were first put up in the great Western Tower."[14] Of this period the following are enumerated as works executed in the monastery[15]: Prior Crauden's chapel, the prior's new hall above the old one, the guest hall, the fair hall, and the residence of the sub-prior.
On the death of Bishop de Lisle in 1361, Walsingham was elected bishop by the convent, but the election was set aside by the pope. This eminent architect was buried in the cathedral, but the precise spot is not known. The epitaph on his tomb has been preserved, and in it we find that he was buried "ante Chorum" (in front of the choir). This would mean the ritual choir as then existing, and would fix the place of his interment approximately at the spot where there is now a large monumental slab, from which the brass has been removed; and this has always been traditionally said to be the actual stone placed over his body. The brass represented an ecclesiastic with mitre and pastoral staff. The objection to this having been Walsingham's memorial, that these emblems could not have been correctly placed upon it, has been thus met: "On the other hand it is contended that although Alan died a Prior of the Convent, he had been elected Bishop by the Monks, though his election was overruled by the Pope, and that seeing to his successor Prior Powcher the Pope gave permission that he and all future Priors of Ely should wear the mitre and carry the crozier, it is possible that the Monks had anticipated somewhat the Pope's edict, and had represented their beloved Prelate with episcopal mitre on his head and crozier in his hand."[16] He well deserved the description in the epitaph, "Flos operatorum" ("The Flower of Craftsmen"). The rich woodwork in the choir—the stalls with their beautiful canopies—is also certainly Walsingham's work.
Besides the great operations of this century there were various alterations and additions made in the cathedral of which the date is not recorded. The triforium in the presbytery was rearranged; the external walls were raised, and the Early English windows of Northwold's work were replaced by much larger ones with Decorated tracery. As the clerestory windows were not altered, the lean-to roof of the triforium was of course made much more flat than before. The graceful flying buttresses, with their elegant pinnacles, are of this same date. The character of Northwold's triforium windows and the corbel table below the parapet may be still seen in two bays on the south side. The aisle windows of the presbytery were also enlarged in the Decorated period; but they are not of the same design as the triforium windows, and they were probably not inserted at the same time. Judging by ordinary methods of discriminating dates by character and style, we should suppose the aisle windows to be earlier than those above; possibly some of this was done by Bishop Barnet (1366-1373). The whole designing is so unlike any of Walsingham's known work that we can hardly suppose that he was the author.
After the extensive changes of the fourteenth century were completed, the fabric of the cathedral was left practically as we see it now. Rearrangements of the interior have taken place on many occasions since, and the numerous side-chapels have been despoiled of their altars; but there has been no material structural change.
From the death of Bishop Barnet in 1373 to the suppression of the monasteries no Bishop of Ely is credited with having done anything towards the fabric of the cathedral except Bishop Gray (1454-1478). Some of them were at variance with the prior and convent, and would be little inclined to spend money on the church. Those that had a taste for architecture displayed it in beautifying their palaces or manor-houses, or upon buildings connected with the universities or other places in which they had private interest. Some were men of great political influence, and found their time and energies fully occupied in matters of national importance. One at least spent immense sums upon the drainage of the fens. Some did indeed erect chapels or shrines in the cathedral, or left provision that they should be erected after their deaths, but these were as memorials of themselves. The monastery carried out whatever was done in the fifteenth and sixteenth centuries as long as the monastery existed. The first such work was begun early in the fifteenth century by Prior Powcher: this was the erection of the upper portion of the western tower. At the top of the tower, before this addition, there was a wooden spire covered with lead. The upper story now is octagonal, and there are also octagonal turrets at the corners, detached, except at top and bottom, from the main body. These were clearly built so as to harmonise with the large projecting turrets—massive enough themselves to be called towers—at the ends of the west front. This octagon was also itself—but probably at a much later date—surmounted with some sort of spire. An engraving dated 1786 shows this spire: it was no improvement to the tower. It was happily removed early in the nineteenth century. This additional story was built without due preparation. The extra weight was too much for the support which had been sufficient for the smaller tower; accordingly casing was added round the four great piers to increase the support. This was in Bishop Gray's time, and he contributed largely towards the cost. "The Prior and Convent were at great charges in repairing the lower part of the Western Tower; the Arches and Pillars of which, being found insufficient for its support, were therefore obliged to be strengthened, by wholly new-casing them with Stone, in the most substantial manner, as we now see them."[17] It has been reasonably conjectured that this extra weight was the cause of the ruin of the northern part of the west transept, or that it was then damaged beyond repair. To Bishop Gray is also assigned in particular the insertion of two windows in the north aisle of the presbytery, near the place where he was afterwards buried. The undoubted Decorated character of the upper stage of the west tower marks it as belonging to the very earliest years of the century. There is not the least tendency towards any features of the Perpendicular style. Without reckoning tombs and chapels, there is no structural work of distinct Perpendicular character to be seen at Ely Cathedral, except some remains of the cloisters, and the windows in the nave aisles and clerestory, and those in the upper parts of the great transept, and the large supporting arches which have been inserted beneath the Norman arches of the west tower. The triforium walls in the nave were raised in the fifteenth century, as those in the presbytery had been raised in the fourteenth. The style of the tracery shews that this alteration was carried out quite late in the century, perhaps about 1480. In the south transept there is also a large Perpendicular window. The very late east window of the south presbytery aisle was inserted as part of Bishop West's Chapel, who died in 1533.
In 1539 the monastery was surrendered to the king. Such of the domestic buildings as were not required for the use of the dean and canons were as usual sold. The Constitution of Henry VIII. provided for the customary officers of a cathedral establishment. The prior became the first dean, and remained in office till his death, eighteen years later. Though the minster had become a cathedral when the bishopric was instituted, yet the prior and convent were always custodians of the fabric, and apparently supreme therein; and there was nothing strictly corresponding to a capitular body. A memory of the fact that the bishop was in place of the abbot remains to this day in the position of the bishop's seat in the choir. There is no throne, properly so called. The bishop occupies what is in most cathedrals the dean's seat—on the south of the entrance at the screen. The north side is in consequence the Decani side, and the Cantoris side is on the south. This position of the dean's stall on the north, though very unusual, is not unique. It occurs also at Durham and Carlisle; but at those cathedrals there is a throne for the bishop, and the bishop's seat in a stall in the south, corresponding to the dean's in the north, is not met with elsewhere. "At Ely alone, of all cathedrals in Christendom, owing to its first bishop having been an abbot who was himself the banished bishop of another see, the diocesan has continued to occupy the abbot's stall, while the head of the corporation (before the Reformation a prior, and since then a dean) has occupied the opposite stall, usually assigned to a sub-prior or sub-dean."[18] There were three Benedictine abbeys which retained their monastic establishment after a bishop had been made and the minster became a cathedral—Canterbury, Durham, and Ely.
It is always taken for granted that the destruction of the beautiful work in the lady-chapel, as well as of the shrines and statuary in the cathedral, was effected very soon after the dissolution of the monastery; but precise authority for this seems not to be forthcoming. It is known that Bishop Goodrich was an ardent supporter of the Reformation movement, and that he issued an injunction in 1541 which would have authorised such destruction. There was no other material damage done to the cathedral at this time. In 1566 a parish church, dedicated to S. Cross, which was situated at the north side of the nave, was found to be so dilapidated that no attempt was made to render it fit for service, and the dean and chapter gave to the parishioners the lady-chapel for a parish church, and it has so remained to this day.
