in the walls. The aisles and ambulatory of the chancel were treated by the same methods. In the triforium gallery, above the transverse arches of the aisles, were other semicircular arches. These served a double purpose: they acted as supports to the timber framework of the aisle roofs, and also as a means of buttressing the upper part of the nave walling in which the clerestory windows were placed. Such other buttresses as there had been were broad and flat, with but little projection from the surface of the wall. The windows throughout the building up to about the end of the twelfth century were small in comparison with some of those which were inserted at various times afterwards.

It has been remarked that the termination of the early chancel towards the east was an apse, and that round this was carried the north and south choir aisles in the form of a continuous ambulatory. From this enclosing aisle—a semi-circle itself in form—three chapels were projected, each with a semicircular apsidal termination. The central one of the three was the lady-chapel. This consisted then of the three

western bays only of the present chapel. The lady-chapel was added about eighty years after the early part of the nave had been built, and has since been much altered.

The presence of this grouping of features is indicative of that influence which Continental architecture had exercised upon English art, and now that Norman government had been established that influence became more directly French. But though so strongly affected by this means, Anglo-Saxon character was always evident in work which was a native expression of the thought and personality of those by whom it was executed.

Thus we see that the plan which Ralph approved for the new church that was to be built for him at Chichester was devised according to accepted traditional arrangement. He adopted no new idea when he decided what general form the cathedral should follow. The disposition of the several parts differed in no wise from that which had been followed during centuries before. The requirements of ritual had decided long since what were those essential features of planning to be insisted upon, for the pattern in germ was shown in the arrangement of the Mosaic Tabernacle. In the earliest plans the same distribution of parts was observed, though at a later date the transept was introduced—an idea which no doubt had its origin in some practical necessity, and was afterwards retained as being representative of an ecclesiastical symbol.

Of the practical and artistic character of the architectural details we shall see more in examining the exterior and the interior of the church. These will lead us, of necessity, to deal more with archaeology in its relation to the history of architecture rather than of this particular church as a building used for ecclesiastical purposes.

After the ceremony of 1184 building operations were continued, but the records available do not tell about anything of much interest for the next two or three years. Then in 1186-1187 a catastrophe occurred—the cathedral was again burnt. But this time the effects of the fire were much more disastrous than had been the case in 1114. So extensive was the destruction that the entire roofing, as well as the internal flat ceiling, was gone; and though we can glean no certain knowledge from documentary evidence, it appears probable

that the eastern section of the building suffered more than any other, for whatever other causes may have aided in the wreck of this part—a weakness in the masonry, an insufficiency in the supports or abutments—the fall of such heavy timbers as those which must have formed the outer roof and inner ceiling of the chancel would in itself be sufficient to wreck the remainder.

Whether the change in plan that now followed was really necessary because of the damage that had been done, or whether the fire provided a welcome opportunity by which new features might be introduced, we are not able to discover. It is sufficient that the chance was not lost, for in the eastern ambulatory of the cathedral church at Chichester is to be seen, as a result, one of the most truly beautiful examples of mediæval design that English architecture now possesses.

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 mediæval 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. Whether any of the actual craftsmen from Canterbury worked again at Chichester or not we cannot tell, but it is evident that the Kentish experience was of great help to Sussex in the new venture. When it had been decided how they should operate, it was natural that the covering of the building must be the first provision. This involved the repair of the shattered clerestory, and then they were free to proceed in other

directions. Further than this we have no means of learning what method was followed in carrying on the new work; but it continued, so that in about twelve years the building was dedicated
