In the nave some parts of the old limestone walls had been injured by the fall of the roofs; they were also seriously damaged by the beams that had been laid upon them, for these, after their fall, would continue to burn as they rested against those portions of walling which remained standing.  It was no doubt by some such cause as this that the early clerestory was disfigured and partly destroyed.  In either case, the old clerestory arcade of the twelfth century no longer remained as it was before; and though there were already stone vaults to the aisles of the nave before the fire occurred, yet they also disappeared and made way for newer ones.  The outer roof over the triforium evidently shared the fate of the other coverings; and the arched abutment in the triforium, which acted as a support to this roof and the walling below the clerestory, now disappeared.  It may be that this arching was not completely destroyed by the fire alone; no doubt some that remained was intentionally removed to prepare the way for the new work.

The same bishop who had witnessed the completion of the earlier operations began with much enterprise to see about the reconstruction, but not the restoration, of what had been destroyed.  Some portions were repaired, others rebuilt; but the greater part of the work now undertaken involved an entire change in the character of some of the principal features of the earlier scheme.  In fact, this incident in the history of our subject gave “occasion to one of the most curious and interesting examples of the methods employed by the mediaeval architects in the repairs of their buildings.” [2]

Having decided that they would, if possible, avoid all future risk of a similar catastrophe, a system of vaulting was adopted as the best solution of the problem,—­this involved necessarily a remodelling of the interior; and so, neglecting the Isle of Wight limestone and the Sussex sandstone, which at first had been the material used for the walling, the masons were directed to use stone of finer texture and smaller grain.  It has been thought by some that this material was brought from Caen in Normandy.  The same stone was used to re-face parts of the nave piers.  And in addition Purbeck marble was selected instead of that which was to be found in Sussex.

It is interesting to remember that the new choir of Canterbury had only been finished about three years before the fire occurred at Chichester.  This work had been begun by William of Sens and finished by William the Englishman; and though it was so large an undertaking, it appears to have been commenced and completed between the years 1174 and 1184.  This would very naturally exert some influence upon the building projects of a neighbouring see.
