“ The thirteenth century aisleless churches of Potterne, in Wiltshire, and Acton Burnell, in Shropshire, are both cruciform in plan. The church at Potterne was planned throughout with reference to [56] the crossing of transepts, nave, and quire, above which its central tower rose: the tower space is the central point of the whole. But, at Acton Burnell, there is no central tower or space: the body of the church consists of a long aisleless nave and an aisleless chancel beyond; and the transeptal chapels are simply stuck on, as it were, to the eastern part of either wall of the nave. ”

“ The most common plan of the aisled church is formed by an aisled nave with a long aisleless chancel, western tower, and south porch. So common is this that it may be spoken of as the normal plan of the larger English parish church. There must have been, we already have said, a very large number of aisleless churches in England at the time of the Conquest. Where Norman builders reconstructed parish churches, they showed a distinct preference for the aisleless plan. But, in many churches, built about or soon after the beginning of the twelfth century, aisles were planned and executed. ”

“ At Santa Sophia, the basilican chancel forms an indissoluble part of a centralised plan; but this feat is beyond the reach of an ordinary architect. Even at San Vitale the planning is highly complicated, and must be due to an [13] architect of some genius. In addition to complications of design, the centralised plan raised questions of roofing which did not trouble the builders of the long wooden-roofed basilicas. The vaulted half-dome of the basilican apse was a simple matter, compared with the mighty dome of Santa Sophia and its cluster of abutting half-domes. ”

“ Great French cathedrals, like Amiens, not only have a complicated series of chapels opening from the aisles of the apse, but have their naves lined with chapels, which were formed by removing the outer walls of the aisles to a level with the outer face of the buttresses. The ordinary parish church had no need of these elaborate arrangements, although in towns and in districts where money was plentiful and its possessors recognised its true source, plans hardly less spacious than those of the cathedral and monastery churches came into being. ”

“ There is one obvious consequence of the setting out of aisles on either side of an existing building which, although an imperfection in itself, contributes greatly to the variety of the parish church plan. The builders cannot see both their aisles at one and the same time: the older church comes in between. In fact, until the nave and aisles are actually joined, at the close of the work, by the breaking down of the walls beneath the arches, there can be no opportunity of appreciating the full effect of the work. ”

“ Others, regarding assemblies of Christians for public worship as, in their essence, meetings of persons associated in common brotherhood, have derived the basilica directly from the aisleless scholae which were the meeting-places of the various confraternities or collegia of ancient Rome. In these there is an apse at one end of the building; and, if we imagine aisles added by the piercing of the walls with rows of arches and columns, we have at once the essential features of the basilican plan. Each theory has its attractions and its difficulties ”

“ In our own day, even in churches where the central tower is carried on high pointed arches, and the view of the altar is practically unhindered, the chancel is cut off from the nave by the crossing, and the acoustic problem, which in modern church planning is so necessary a consideration, is almost insurmountable. ”

“ The plans of Bampton, Burford, and Witney, show how the builders of west Oxfordshire experimented in cruciform planning. The division between chancel and nave is felt much less at Witney than in the other two churches; for the great thirteenth century tower and spire, resting upon massive piers joined by pointed arches, throw a considerable portion of their weight upon nave and transept arcades, whose exceptional massiveness gives unity to the whole design. ”

“ One very important consequence of the addition of aisles and chantry chapels to chancels, at any rate on a large scale, is seen where they are applied to plans originally cruciform. We have already seen that at St Mary's, Shrewsbury, and at Arksey, although much of the fabric of the old transepts was left, broad chancel chapels tended to obliterate [122] the cruciform character of the building. The transepts at Spalding almost escape notice, owing to the double aisle on the south side of the nave, the aisle and north chapel on the opposite side, and the large chapel east of the south transept. ”

“ In our own day a congregation, driven out by builders or restorers, can resort to a school room or mission room. In the middle ages, these alternatives were unknown; and the church was positively indispensable. With this in view, the builders were obliged to add their aisles without touching more of the main fabric than they could help. Usually, then, they took the length of the existing aisleless building for the length of their aisles. They then set out the aisles upon either side of the church, building the outer walls, and dividing them into bays by external buttresses. ”

“ The long nave provides the necessary accommodation for worshippers, the raised apse gives a theatre for the performance of service within view of everybody, the aisles facilitate the going and coming of the congregation, and prevent over-crowding. The centralised plan provides, it is true, a large central area conveniently near the altar; but the provision of a chancel or altar-space necessitates the grafting on the plan of a feature borrowed from the ordinary basilica, which, as at San Vitale, breaks the symmetry of the design. ”

“ When they came to build the arcades, they were conscious of their previous error, and planned them in five equal bays irrespective of the plan of the aisles. In churches of the fourteenth and fifteenth centuries, especially in districts like Norfolk or south Lincolnshire, where much rebuilding was done, the regularity of plan is often remarkable. The nave of the famous church of Heckington, near Sleaford, was planned with an exact correspondence between aisles and arcades: pier is opposite buttress, window opposite window. Islip and Brampton Ash in Northamptonshire show an equal accuracy. ”

“ It is obvious that, from necessary considerations of space, much has been omitted. The elevation of the building, and the treatment of its decorative features, window-tracery, sculpture, etc., belong to another and wider branch of architectural study, in which the parish church pursues the same line of structural development as the cathedral or monastic church, and the architectural forms of the timber-roofed building follow the example set by the larger churches with their roofs of stone. ”

“ The usefulness of aisles is at once apparent. They afford greater space for the distribution of the congregation. The aisleless church may be inconveniently crowded from wall to wall: on the other hand, where spaces are left between the nave and side walls, the congregation will mass itself in the nave, but the aisles will be left free until the nave is filled, and thus there will be free access through the side doorways for as long a time as possible. Aisles also afford a clear space for processions, and allow them to turn inside the church at a certain point and without difficulty. ”

“ The splendid timber roofs of nave and aisles gained in effect, if they formed, as at Southwold, or in the churches of Norwich, an unbroken covering to the church from end to end. In Norfolk and Suffolk, where the work of rebuilding began in the fourteenth century, as at Cawston, Worstead, or Tunstead, the chancel arch was often kept. At Worstead and other Norfolk churches the method pursued by the builders was precisely opposite to that which we have seen employed by Gloucestershire masons at Cirencester and other places, and may see in most of the fifteenth century churches of Somerset. ”

“ Builders in remote, and especially in hilly, districts, from Saxon times to the present day, have naturally restricted themselves to plans which require as little cost as possible to carry out. Local building material is also an important consideration. In districts where good building stone is to be obtained on the spot, or where money is plentiful and water carriage is possible, the development of plan is naturally rapid, and every fifty years or so, additions to churches will be made in which the old plan will become entirely transformed. ”

“ 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. ”

“ In one respect the plan of St Pancras at Canterbury is allied to that of the church at Bradford-on-Avon in Wiltshire. At Bradford there remains one of the two porches, which also were probably side chapels, projecting from the sides of the nave. But at Bradford the remaining porch is larger in proportion to the nave than is the case at St Pancras. There is no entrance porch on the west side. Further, the chancel at Bradford is rectangular, not apsidal. Instead of a screen-wall with a central opening nine feet wide, the wall dividing nave from chancel is pierced by a small arch only 3 ft. ”

“ If an untouched Saxon nave is a rare thing, an unaltered Saxon chancel is obviously rarer. The small rectangular chancel of the large medieval church at Repton, in Derbyshire, is practically unique; it was probably preserved for the sake of the crypt beneath, which, at first a plain rectangular chamber, was subsequently, but still in pre-Conquest times, vaulted in compartments supported by columns. ”

“ The tower will thus be introduced between nave and chancel, either as an independent structure, or as an upward extension of part of the side walls. The transepts thus, as at Stow, can be raised to an equal height with nave and chancel. From this to a plan in which the component parts are recognised as interdependent, and are closely knit together in structural unity, is an obvious step. At this point, architectural skill, as distinct from mere building ingenuity, comes into play. ”

“ If we try to trace any principle of development in its plan, we find that this develop [3] ment is directly inverse to that of the Christian basilica. The secular basilica, in earlier examples a colonnaded building with its central space open to the sky, became at a later time a roofed hall, either, as in the case of the basilica at Trier, without aisles, or, like the basilica of Maxentius or Constantine in the Roman forum, with a series of deep recesses at the side, the vaulted roofs of which served to counteract the outward pressure of the main vault. ”

“ As we have seen, the building of the aisles at Newark upon their present scale did not begin till much later. The work of rebuilding at Grantham was clearly inspired by that already begun at Newark. A tower was planned on a site much to the west of the nave, [90] and was engaged within very broad aisles. The tower and north aisle were set out first. The north aisle was divided into seven bays, with a large traceried window in each bay, the western bay being much wider between the buttresses than the rest, owing to the greater space taken up by the tower and its piers internally. ”

“ If errors like this could take place in churches where the width of the bays of the aisles was calculated, they were much more likely to take place where builders worked with less accurate ideas of measurement. In an unvaulted church, where the pressure of the roof is not a serious factor in the construction, the exact correspondence of pier to buttress need not be taken into account; and there are many churches in which the spacing of the aisles is quite independent of that of the arcades. This happens at Melbourne, where the church was not planned for stone vaulting. ”

“ Again, it may be that, by accident or design, the backing for the responds may project more on one side of the nave than on the other, at either or both ends. The result will be that the piers of one arcade will be out of line with those of the arcade opposite. That discrepancies of this kind were sometimes the result of intention cannot be denied; but there is generally some practical reason to be found for the intention, and the discrepancies themselves were a pis aller which the builders would have avoided, if they could. ”

“ In Yorkshire, where the number of Norman rectangular chancels is large, and buildings such as Adel exhibit the aisleless church in its highest state of architectural development, the number of apsidal chancels can [50] be counted on the fingers of one hand. In Sussex, where Caen stone was largely used, and we should expect foreign influence to be noticeable, the proportion of apsidal chancels is small. In Gloucestershire, the Cotswold district contains several small Norman churches, which have been little altered: the rectangular chancel is universal. ”
