Not very much remains to-day of this thirteenth-century Early English choir. In 1292, just as it had been roofed in, a terrible fire, the most disastrous the cathedral has ever experienced, destroyed everything except the outer walls of the aisles, the graceful lancet windows, and the beautiful cinque-foiled arcading beneath them. Belfry and bells, too, shared in the destruction. One hundred years passed away while a new choir was being built. Bishop Halton (1292-1325), a very energetic prelate, and a great favourite of Edward I., began the work, and laboured at it for quite thirty years, and was followed by Bishops Kirkby, Welton, and Appleby. It was arranged to rebuild the choir on a still larger scale, a bay being added, and the east end rebuilt from the foundation. The general plan of the earlier work of the aisles was followed in the new bay. The glory of the cathedral--the great east window, which marks a distinct transition in art--was also projected, but at this time only carried up as high as the top of the choir arches. The wall arcade and the lancet windows above were repaired, and later work of a more elaborate character added. The great arches, and the groin ribs of the aisle ceilings were underset with new pillars; so that we get Early English _arches_ of the thirteenth century on Decorated _pillars_ of the fourteenth century. After some years interval, building was resumed about 1350. The Decorated portions of the choir were now put in hand: the triforium, clerestory, and upper part of the east end, as well as the tracery and much of the mouldings of the east window and the roof. The carving, hitherto unfinished, was now completed; but, as the style had developed in the mean-time, we once more find examples of decidedly early work with much later work both above and below. The roof inside was finished with a very fine panelled ceiling. The building was finished 1375-1400, and in the roof were placed the arms of those who had helped in the rebuilding--the Lacys, the Nevilles, and the Percys. The material used for the new choir was red sandstone, both for the interior and the exterior, giving in some cases a curious patched appearance to the walls.

In 1392 the cathedral once again suffered from fire, and the damage was repaired by Bishop Strickland (1400-19). No efforts appear to have been made to bring the nave into correspondence with the extended choir, and the end of the thirteenth century marks the close of the cathedral's history in the direction of its enlargement and beautifying. On a review of the cathedral we find in the aisles thirteenth-century work, on a small scale, in its perfection. The south aisle shows development of window tracery, and the gradual steps taken towards uniting single lights under one arch.
