§ 46. Hitherto we have spoken of the aisled nave as though both aisles were planned at one and the same time. This, however, was by no means always the case. At Gretton in Northamptonshire, the north aisle was built soon after the beginning of the twelfth century: the south aisle followed twenty or thirty years later. The north arcade at Northallerton is of massive twelfth century work, with rounded arches: the south arcade was added in the thirteenth century, and has slender columns with pointed arches. In such cases, the north aisle may have been built first, to avoid interference with the burial ground south of the church. Very often only one aisle was added. The little church of Whitwell, Rutland, has a south aisle, added in the fourteenth century, with a chapel at its east end. No north aisle was built: but a drain in the north wall of the nave shows that there was a third altar against the north side of the rood screen. Usually, when one aisle was built long after another, the spacing of the new arcade was made to correspond with that of the old. If the old arcade had heavy twelfth century columns, the new one, with its lighter columns, would have broader arches. But it sometimes happens that the old spacing was disregarded, for very good reasons. The north arcade of Middleton Tyas church, in north Yorkshire, consists of six bays: the columns are heavy, the arches low and round headed, and very narrow. The interior of the church must have been very dark; and the builders of the south aisle, in the fourteenth century, aimed at throwing more light upon it. They therefore planned their new arcade, with broad pointed arches springing from octagonal columns, in four instead of six bays, and so, from broad windows in the aisle, introduced the necessary light. Something of the same kind happened at Theddingworth in Leicestershire: the effect is, of course, one-sided, but in both cases the light admitted enhances the merits of the earlier arcade, which, until then, had to be taken on trust.
§ 47. But there are further instances—and these, perhaps, are the most instructive—where aisles were not merely built at two different periods, but where the growth of one or both aisles was gradual. As an instance of this, may be cited the beautiful church of Raunds in Northamptonshire. Raunds seems to have been one of those cases in which the Norman chancel and nave were of the same width, and possibly were undivided by any chancel arch. In the thirteenth century the west tower and spire were built, and a broad south aisle was added to the nave. This aisle was of four bays, and the point at which it stopped probably marked the dividing line between the nave and chancel. However, the builders certainly intended to carry on the aisle eastward, as a south chapel to the chancel, which they now rebuilt and lengthened. Early in the fourteenth century, the south aisle was continued eastward, an arcade of five bays being added to the four bays already existing. The new bays were made rather narrower than those in the earlier part of the arcade. A strange feature of the new work was the insertion of a chancel arch, the south pier of which bisects one of the new arches. Thus, while three bays and a half of the new arcade belong to the chancel and quire, a bay and a half belong to the nave. The arch dividing the south aisle from the chancel chapel springs from the pier between the end of the old arcade and the inserted pier of the chancel arch. At the same time, the outer wall of the south aisle seems to have been practically rebuilt, although much of the older work was retained. There may have been a thirteenth century north aisle as well. Whether this was the case or no, a new north aisle and arcade were built during the fourteenth century. The aisle was set out in seven bays, six of which contained broad three-light windows, while a north doorway was made in the third bay from the west end. The east wall was built on foundations in a line with the chancel arch, while the west wall was in a line with the tower arch and west wall of the south aisle. It is obvious, therefore, that the planning of the new aisle was totally different from that of the older aisle and chapel. However, when the builders came to their arcade, instead of building it in seven bays, as the new aisle demanded, they built it in five, setting their new columns in a line with those on the opposite side. But while, on the south side, there was an awkward half-bay between the end of the arcade and the chancel arch, a solid piece of wall was left between the north pier of the chancel arch and the eastern respond of the new arcade. A compromise was thus effected between the aisles, and an appearance of regularity was ensured. Directly, however, one begins to examine the plan of the church, and to trace the transverse lines from window to window, and buttress to buttress, it will be found that only in one place can a line be drawn which will pass straight from the centre of one buttress to that of the buttress opposite, and will pass through the centre of the intervening columns on its way.

§ 48. It already has been shown that builders were very unwilling, in making their additions to churches, to destroy old work altogether. At times they displayed an extraordinary conservatism in their re-use of old material in their new work. This was not invariable. In the splendid churches of south Lincolnshire, during the fourteenth century, their aim seems to have been complete rebuilding; and such examples as the magnificent nave at Swaton, near Sleaford, or the neighbouring church of Billingborough, show how old work must have been swept away by the enthusiasm for lofty arcades, elaborately traceried windows, and walls of dressed stone-work. On the other hand, half the charm of the hardly less beautiful churches of Northamptonshire is the result of the clever way in which the masons dove-tailed all the old stone-work which was worth preserving into their new additions. Such churches as Tansor and Oundle are, for that reason, unexcelled in interest, offering, as they do, almost inexhaustible problems as to the development of their plan. In all parts of England we find that builders, whatever else they destroyed, carefully kept, as a general rule, the doorways, and especially the south doorway, of the buildings which they enlarged. This accounts for the large number of handsome Norman doorways which remain in the walls of aisles obviously later than the doorways themselves. At Birkin in Yorkshire, the south aisle was not built till the middle of the fourteenth century, but the doorway was removed to its new position from the wall of the aisleless church. One very exceptional case occurs at Felton in Northumberland. Towards the beginning of the thirteenth century, the west part of the south wall of the church was cut through, a chapel was added, and, east of the chapel, a porch was built. Rather more than fifty or sixty years later, it was determined to add a south aisle the full length of the nave. The width of the aisle was taken from that of the existing chapel and porch. To connect the chapel with the new work, the side walls of the porch were cut through. The outer doorway of the porch became the new south doorway, while the inner doorway was kept unaltered, as an arch in the new arcade.
§ 49. Features which have been touched upon in connexion with Raunds bring us to two new features in the plan—the rebuilding of aisles and the lengthening of churches westward. In most parish churches, aisles, when they were added at first, were extremely narrow. The west wall of Hallaton church in Leicestershire, for example, shows that, in the fourteenth century, originally narrow aisles were heightened and widened. The roof lines of the earlier aisles remain; they were clearly under the same roof as the nave of the church, and had very low side walls. This was not always the case. At Raunds the thirteenth century south aisle was always broad and lofty, and must have had its own roof from the first. And, as the principles of Gothic construction became more familiar, and the larger churches began to exercise a more wide-spread influence upon the parish church, aisles began to increase in breadth and elevation. The small and narrow windows of churches of the twelfth and early thirteenth centuries gave way to the broad mullioned and traceried windows of fully developed Gothic work. For these, with their advantage of increased light, more headway was necessary. Aisle walls were consequently heightened or altogether rebuilt. The acutely pointed roof of the nave could no longer be continued downwards to cover these higher aisles. The aisle was consequently covered with a lean-to roof, or with a separate gabled roof of its own. A free increase in width was thus possible. The church of Appleton-le-Street in Yorkshire has a short nave with north and south aisles. The north aisle, added in the early part of the thirteenth century, is narrow, and the roof of the nave was continued over it. The south aisle, which was probably rebuilt a little before 1300, is broader and has a separate lean-to roof. The wide east window of this aisle could not have been introduced, had the south aisle been built to match the scale of the north aisle.

§ 50. The introduction of more light, however, was not the only reason for the rebuilding and heightening of aisles. The east end of an aisle, as has been said, provided a convenient place for one of the side altars of the church. This was the case even in the narrow aisles of the twelfth and thirteenth century, many of which, like the north aisle of Great Easton church in Leicestershire, provided with a drain, aumbry, or a corbel for a statue, bear witness to the existence of a contemporary altar. At Harringworth in Northamptonshire there had been an aisleless church, to which a tower had been added at the end of the twelfth, and aisles early in the thirteenth century. On 24 October 1305 Edward I granted letters patent to William la Zouche, by which he had licence to assign a certain amount of land to two chantry chaplains in the chapel of All Saints. This may have been his private chapel, but was possibly in the church. A little earlier than this, to judge by the character of the architecture, a new north aisle had been built, with a new altar at the east end. Very soon after the granting of the licence, it would appear that the whole of the south arcade was taken down, and a new south aisle and arcade built. The work was done in a very conservative spirit, for the old thirteenth century porch and inner doorway were rebuilt on the new site, and an old string-course was re-used internally, beneath the new windows. The piscina and the three sedilia, which belonged to the altar at the end of the aisle, remain in the south wall, and there are corbels for statues on either side of the east window. However, rebuilding did not stop here; for it seems that, during the next few years, the north arcade was entirely rebuilt so as nearly to match that on the south. Thus the work, beginning with the north aisle, and extending over some thirty or forty years, finished on the side on which it began. Numerous examples of a closely parallel kind, fortified by documentary evidence, might be given.
