Another period of disturbance follows the comparatively quiet rule of Bishop De Lucy, and it is not until we reach 1346 that we come to a fresh outburst of architectural zeal on the part of the incumbents of Winchester. But Edingdon, and still more his successor Wykeham, left very lasting monuments of their occupancy at Winchester. It must not be forgotten that, while to Wykeham is due the credit of most of the actual transformation of the building, Edingdon must have first conceived, however vaguely, the design. Edingdon's attachment to Winchester is well illustrated by his quaint reason for refusing the offer of Canterbury: "if Canterbury is the higher rack, Winchester is the better manger." He is, indeed, charged with having left a considerable debt on the building, since his successor seems to have recovered a large sum from his executors, who had also to compensate Wykeham for large numbers of cattle which had "disappeared from the various farms of the bishopric." Yet it appears from Edingdon's own will that he began rebuilding the nave and left money for the continuation of the work. Wykeham, as we shall see, had already a reputation for architectural skill when first introduced to Edward III., and this reputation stood him in good stead in the matter of preferment. When he was elected to Winchester he found the bishop's palaces of Farnham, Wolvesey, Waltham, and Southwark in a very dilapidated condition, and he set these in order before he turned his attention to anything else. New College, Oxford, and Winchester College practically occupied him up to 1393; whilst his work in the cathedral was really the last great undertaking of his life, inasmuch as it was not finished at the time of his death. The actual method of Wykeham's transformation of the interior is described more fully elsewhere, and we will not therefore do more than quote a few words from Willis on the work done. "The old Norman cathedral was cast nearly throughout its length and breadth into a new form; the double tier of arches in its peristyle was turned into one, by the removal of the lower arch, and clothed with Caen casings in the Perpendicular style. The old wooden ceilings were replaced with stone vaultings, enriched with elegant carvings and cognizances. Scarcely less than a total rebuilding is involved in this hazardous and expensive operation, carried on during ten years with a systematic order worthy of remark and imitation.... Judging from the provision of his will of the expenditure for the last year and a half, the cost of this great work to the bishop in present money cannot be estimated at less than L200,000."
