In 1362 John of Thoresby became archbishop. The times were unpropitious for building. Yorkshire was suffering much from the black death, there was great poverty among the peasantry, and the diocese was in great need of discipline and reform. Thoresby gave himself up for nine years to this work, and in 1361 he thought the time had come for the rebuilding of the choir. We have already seen how at York, one great work led to another. The transepts were rebuilt that they might be in harmony with the grandeur of Roger's choir, the nave that it might not be eclipsed by the transepts; and now it was contended that the choir must not be inferior to the rest of the church. Therefore, on the 20th of July 1361, it was resolved by the archbishop and chapter that "It was right that every church whatsoever should agree in the fitting decoration of each particular part, and that the choir in particular, where the holy sacrifice of the mass took place, should be especially rich in ornament." Thereupon they decided to rebuild the choir. The foundation stone was laid on the 30th July 1361, and the work was begun at the extreme east end. There was a very good reason for this procedure. The design of the new choir, both as to size and the planning of the bays, was modelled on that of the nave. It was Thoresby's object to build the largest and most magnificent choir in England. It was therefore both wider, loftier, and longer than that of Roger's, and beginning at the east end it was possible to complete almost the whole of the portion east of the altar as it now stands—that is to say, the presbytery, without interfering with Roger's choir. While, therefore, the presbytery was being built, the service of the church was still carried on in Roger's choir, and only the aisles behind Roger's east end were destroyed. Even when the four bays of the presbytery were completed, say about 1370, it was possible to continue the aisles of the new choir proper without interfering with Roger's work, except to pull down the towers flanking it, so much wider was the new building than the old. Even Roger's transepts did not extend beyond the aisle walls of the new choir, and their place was taken by the present eastern transepts, which are each merely a bay of the aisle, raised to the same height as the vault of the choir itself, and open to the choir from top to bottom.
There has been a dispute whether or no this presbytery was completed in Thoresby's lifetime. According to Stubbs, Thoresby provided tombs for six of his predecessors, and placed them in the choir in front of the lady chapel—that is to say, in the presbytery.
He also says that Idem Archiepiscopus ...Capellam ...Virginis Mariae Mirabili arte Sculpturae atque notabili pictura peregit.
The building must certainly have been roofed before it was decorated, and if Stubbs is accurate, and there is no reason to suppose that he is not, the work was completed by Thoresby. Thoresby died in 1373, and if he finished the presbytery, there was a gap of seven or eight years between its completion and the beginning of the choir. There is internal evidence to support this presumption. The presbytery, though Perpendicular in its main features, shows many traces of the transition from the curvilinear Decorated to the Perpendicular style, especially in the tracery of the great east window and the clerestory windows. In the choir proper these traces have vanished, and the work, though apparently of the same character as that in the presbytery, is altogether Perpendicular. A lapse of ten years in the continuity of the work would account for this change, and becomes still more probable when we consider that the circumstances of the time were not favourable for great expenditure on building. The presbytery had been completed unusually quickly. Indeed, we know that £627 were spent upon it in one year, and this was an unusual amount. The average expenditure, for instance, on the choir of Ely was £318. It was natural, therefore, that there should be a halt to collect further funds. The work of the choir itself proceeded much more slowly. There was a complaint in 1390 on the archbishop's visitation—quod fabrica ecclesiae negligenter tardatur—and it was not roofed in until 1400.
The contract for the glazing of the great east window is December 10, 1405—that is to say, thirty years and more from the date of its construction. But there is nothing unusual in this. It was customary before filling windows with stained glass to cover them with linen cloth which admitted a sufficient amount of light, or to glaze them with plain glass; and it was only natural that a long time should elapse before stained glass could be supplied to the largest window in the world. Burying was begun at the east end soon after 1400, and Scrope was buried there in 1405. Bowet's monument also was erected there in 1415, while he was still alive.
A new high altar was projected in 1418, and the new crypt was fitted with iron work and paved in the same year. The building of the choir had caused a subsidence in the crypt, so the work of Roger and others was broken into fragments and patched together, older capitals being placed on Roger's pillars, in the condition in which we now see it. Nothing is known of the history of the vaults of the cahoir and eastern transepts. Like those of the nave and transepts, they are of wood, though of the same shape and design as a stone vault.
The great central tower was erected between 1400 and 1423. Hitherto there had been the Early English tower of the elder John Romeyn, supported by Norman piers which, perhaps, had received a partial casing of Early English stonework. These piers were afterwards recased, not simultaneously, but as the arches between them were erected, in the following manner:—
Taking the south-western pier for an example: when the present nave was begun, the western face of the pier was cased with masonry, so that three parts still remained Norman; when the Decorated arch[[1]] in the transept was erected south of it, it received a further Decorated casing on its south side; when the central tower was built, its northern and eastern faces were cased with Perpendicular masonry: so, in the case of the north and south-eastern piers, their eastern faces were completely cased when the choir was built, their western only when the tower was in course of erection. To this day it may be seen that there is no bond between the different periods of masonry, and that the courses are at different levels.
The piers were probably completely recased by 1409.
