The Ground Plan of the English Parish Church Part 2

- 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.

[Ill.u.s.tration: Fig. 11. Plan of Harringworth church, Northants.]

- 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 a.s.sign 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 doc.u.mentary evidence, might be given.

[Ill.u.s.tration: Fig. 12. Plans of Grantham church: (1) probable arrangement about 1190; (2) at beginning of 14th century.]

- 51. The rebuilding of the south aisle, about 1313, at Newark, was the prelude to an entire rebuilding of the church, which extended over many years. The builders began by setting out their aisles as usual, and by the middle of the fourteenth century the south aisle was finished, and the lower courses of the north aisle and the new aisled chancel were built. However, in 1349, the Black Death interrupted the work. The north aisle and chancel were not completed, and the new arcades of nave and chancel were not built until the fifteenth century. In this case there were certainly older, and almost certainly narrower aisles. The rebuilding included aisles on a larger scale, and new internal arcades whose s.p.a.cing corresponded to the s.p.a.cing of the aisle walls. All systematic rebuilding, in the full development of Gothic art, began with the planning of the aisles. The naves of Cirencester and Northleach churches, rebuilt at the end of the middle ages, are examples of this method. The arcades at Cirencester are known to have been built about 1514-5; but the aisles were obviously completed first, and their remodelling may have been begun in the second quarter of the fifteenth century. At Northleach the nave was finished about 1458; and there seems to have been a break of some years between the building of the aisles and the destruction of the older church which, no doubt, lay within them. But it did not always happen that the full intention of the builders was carried out. One of the most splendid schemes which we possess for the enlargement of a parish church was the great enterprise begun at Grantham soon after the middle of the thirteenth century. An aisleless Norman church had been enlarged at the end of the twelfth century by the addition of aisles to the nave, the connexion being formed by arcades of rounded arches springing from very elegant cl.u.s.tered columns. Above the arcades were low clerestories, lighted by round-headed windows. About 1230, the neighbouring church of Newark was taken in hand by masons, who built a new west tower up to a certain height, and, as an afterthought, planned aisles to engage the tower completely. 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, 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 b.u.t.tresses than the rest, owing to the greater s.p.a.ce taken up by the tower and its piers internally. The remaining six bays were set out with equal widths between the b.u.t.tresses, the middle bay of the aisle being covered by a porch. The eastern bay overlapped the western part of the aisleless chancel, its western b.u.t.tress being in a line with the division between chancel and nave. The western bay of the south aisle was set out about the same time, and there was, no doubt, an intention of proceeding with the rest on the same lines as in the north aisle.

There can also be little doubt that the builders intended to take down the old arcades, and build new arcades, with s.p.a.cing corresponding to that of their aisles, and to lengthen the chancel eastwards, while bringing its western portion into the nave. The tower and north aisle were built on the intended scale; and, when the tower had risen to a certain height, the ambition of the builders was fired to add to it an extra stage, hitherto uncontemplated, below the spire with which it was to be crowned. This project of giving their church a tower and stone spire, which remained, for many years, the loftiest in England, evidently curtailed the full accomplishment of their earlier plan. The columns of the old arcades were kept, and the tower was connected by arcades of two bays with the angles of the west wall of the old church; while an arch was pierced through the north wall of the chancel, to give access to the east bay of the new aisle. The new arches were pointed: in order to match them, the older round-headed arches were taken down, and pointed arches built, which cut into and blocked the clerestory windows.

This change was made with great economy of material, the springing stones of some of the old arches being kept to afford footing for the new. When the south aisle was seriously begun, about 1300, similar economy was shown. Four bays, in addition to the western bay, were s.p.a.ced out, without regard to the plan of the north aisle. The fourth bay from the west was covered by a porch, smaller than that on the north side; and the east wall of the aisle was probably built on a line with the division between nave and chancel. Half a century later, the east wall was taken down, and the south aisle was extended to the full length of the chancel; but this later development was not contemplated by the thirteenth century builders. These hesitations and changes, consequent upon the expense entailed by the north aisle and by the alteration in the elevation of the tower and spire, make Grantham second to no English church in interest.

- 52. Grantham also provides us with a lengthened nave. The position of its earlier west wall is clearly shown by the ma.s.ses of masonry which occur between the eastern bay of the new, and western bay of the old, arcade on either side. The responds on the eastern side of these pieces of wall are twelfth century work: on the west side, they belong to the later part of the thirteenth century. Such lengthening was probably very common in later Gothic times, and we may surmise that it took place in many instances where arcades were entirely rebuilt, and no visible trace of the process was left. However, there are many churches in which one or more extra bays have been added to the nave, and the join of the old and new work is marked as at Grantham. Whaplode church in south Lincolnshire had its early twelfth century nave lengthened by three bays about 1180. At Colsterworth, near Grantham, a western bay was added to the nave about the same time, and an earlier north aisle lengthened.

Above the piece of wall which occurs between the older and newer work, the quoins of the aisleless church remain entire. Usually, as at Grantham, the lengthening of the nave was undertaken in connexion with a new western tower, which was built up outside the church, and then connected with it by one or two bays of arcading. Almost contemporary with the tower and spire of Grantham are those of Tilney All Saints, near Lynn. Here a single bay was added west of the late twelfth century nave; and, as no new aisles were contemplated, the old arcades, with their rounded arches, were left intact. Bubwith in Yorkshire, and Caunton in Nottinghamshire, are later examples of churches where the tower was built west of the end of an earlier nave, and a bay was built to connect it with the older work. Sometimes, as at Gretton in Northamptonshire, where the slope of a steep hill forbade extension far to the west, a new tower was built only a few feet beyond the limit of the old nave. In such a case, the side walls of the nave might be carried solid westwards to meet the tower, or, as happened at Gretton, narrow arches might be made between the tower and the west end of the older wall. The beautiful tower and spire at Oundle were built just outside the west wall of the thirteenth century nave; and were doubtless intended to be followed by a complete rebuilding of the arcades--such a rebuilding as took place at Lavenham in Suffolk, towards the end of the fifteenth century. The idea, however, was abandoned, and the s.p.a.ce between the arcades and the tower filled in solid with rather rough masonry.

[Ill.u.s.tration: Fig. 13. Gretton, Northants: extension of 12th century arcade to meet 15th century tower.]

- 53. The position of the western tower in the plan is normally at the west end of the nave, with which it is connected by an arch, low at first, but loftier as time goes on, until, in later Gothic churches, its height frequently is nearly that of the whole nave. The remaining three walls are usually external, and clear of the aisles. But sometimes, owing to a freak of planning, or, more frequently, owing to the conditions of the site, the tower is, as at Bibury, at the west end of one of the aisles. At Gedling in Nottinghamshire the tower and spire are at the end of the north aisle. The tower of St Michael's, Cambridge, is at the west end of the south aisle: probably the western extension of the church was prevented by the neighbourhood of the street, a circ.u.mstance which often accounts for the irregularity of plan in some town churches. At St Mary Redcliffe, Bristol, built on the edge of the "red cliff" from which it takes its name, the tower and spire are at the end of the north aisle: had they been planned in the usual place, a full bay of the nave would have been sacrificed. The tower at Spalding was planned, in the first instance, to stand against the south wall of the west bay of the south aisle: subsequently a new south aisle was built east of it. One of the most curious instances is that of St Mary's at Leicester, where the tower, subsequently, as at Spalding, heightened by a spire, was planned in the thirteenth century, outside a very narrow south aisle. A tower at the west end of the nave would have encroached upon the inner ward of the adjacent castle. The chancel of St Mary's was used for collegiate services, and parochial accommodation was limited.

Towards the end of the thirteenth century, a very wide south aisle, a parish church in itself, was built the full length of the nave, and overlapping the chancel at the east end. The tower was left standing on piers entirely within the west end of the new aisle. It may be added that, where towers occur at the end of aisles, they seldom project beyond the west wall of the nave, but open into the nave by an arch in the north or south wall, as the case may be. Plans with two western towers, as at Melbourne or St Margaret's at Lynn, are of very rare occurrence; and, where they are found, the plan was probably designed on more ambitious lines than those of the ordinary parish church.

- 54. The plan in which the western tower is engaged within the aisles--that is, where the aisles are brought up flush with the west end of the church--is not very common. Still, instances occur in all parts of England. At Grantham, the plan is deliberate. It was imitated, as has been said, from Newark, where the side walls of the tower had been pierced with arches as an after-thought. Newark, in turn, may have taken the design from Tickhill in south Yorkshire; and the design at Tickhill may have been taken from the early and unpretentious example at Sherburn-in-Elmet. Grantham probably suggested other similar designs, such as Ewerby, near Sleaford. Several of our finest late Gothic churches, like St Nicholas at Newcastle, have plans in which the aisles are continued up to the west face of the tower. The method affords full development to the aisles, and, as at Sileby in Leicestershire, has an imposing interior effect. Outside, however, the aisles crowd the base of the tower too much, and the fine effect of a lofty, free standing tower is lost. Sometimes aisles were extended westwards, so as to engage an earlier tower, as at Sleaford, where the low tower and spire are almost overwhelmed by a pair of wide fourteenth century aisles. At Brigstock and Winterton, late Saxon towers have been left without alteration inside aisles which have been brought westward in the thirteenth and fourteenth centuries. The nave of Holy Trinity, Cambridge, was much widened in the fourteenth century, and a small tower and spire of earlier date were brought entirely within the new nave, as happened in the south aisle at St Mary's, Leicester, and were left without sufficient abutment. As a consequence, the arches of the ground story had to be strengthened about a century later with additional masonry.

Cases occur, as at Coln Rogers in Gloucestershire, where a tower has been built within the west end of an earlier church. In most of such instances, the churchyard boundary probably allowed of no further building westward. The nearness of the churchyard boundary also seems to have given cause to a peculiarity which may be seen at Wollaton, near Nottingham, Dedham in Ess.e.x, and in a few other places, where the west tower is in its usual position, but is pierced from north to south by an archway. It is possible that this gave facility to processions, which could thus pa.s.s round the church without leaving consecrated ground. The tower of old All Saints, Cambridge, now destroyed, projected over the public foot-way of the street, which pa.s.sed through its ground story; while St John's, Bristol, is built on the city wall, and the tower and spire, which it shared with the adjoining church of St Lawrence, are over the south gate of the city.

- 55. Sometimes, as at Oundle, the tower was rebuilt with a view to the reconstruction of the whole church. But, as also at Oundle, the design was often abandoned, or was altered. The magnificent tower of St Michael's, Coventry, was built, between 1373 and 1394, at the west end of an older nave: its spire was not begun till 1430. Whether the rebuilding of the nave was contemplated when the tower was begun, it is impossible to say. A new nave was actually begun in 1432, and finished in 1450. A thoroughfare immediately south of the church prevented extension on that side. The old south porch was retained in place as the princ.i.p.al entrance, so that the line of the wall of the south aisle follows closely that of the original church. The new south arcade was set out, not in a line with the south-east b.u.t.tress of the tower, but somewhat to the north of it, so that the b.u.t.tress is external; while, for the width of the nave, a s.p.a.ce approximating to twice the internal breadth of the tower was taken. The tower is thus placed almost wholly south of the central axis of the nave produced westward. Here, once more, we may note the influence of site on the plan.

- 56. The people's entrance to the church was ordinarily through a porch, covering the north or south doorway of the nave. The south doorway is usually covered by a porch. Frequently, as at Hallaton in Leicestershire, or Henbury in Gloucestershire, there is a north as well as a south porch. At Warmington, near Oundle, where there is a beautiful doorway in the west tower, the vaulted south porch is the princ.i.p.al entrance; but there is also a somewhat smaller north porch, also vaulted. The chief porch at Grantham is on the north side; but there is also a large porch on the south. At Newark, there is only a south porch, on the side of the church next the market place. The south porch of St Mary Redcliffe, at Bristol, is the ordinary entrance of the church; but the chief entrance of the building, until the fifteenth century, was on the north side, at the head of the abrupt slope towards the city. In the fourteenth century, this entrance was covered by a large and lofty octagonal porch, approached by a flight of steps. There is an octagonal south porch at Chipping Norton, and a hexagonal south porch at Ludlow.

The magnificent porches of the fifteenth century, as at Burford in Oxfordshire, Northleach in Gloucestershire, Worstead in Norfolk, Walberswick in Suffolk, St Mary Magdalene's at Taunton, or Yatton in Somerset, are usually on the south side of the church.

- 57. The positions of the porch and doorway in the wall of the aisle vary. At St Nicholas, Newcastle, where the west tower is engaged within the aisles, there is a porch in the western bay of each aisle. Usually, however, the porch will be found in the second bay of one of the aisles, counting from the west end. Sometimes, especially in larger churches, the porch occurs a bay further east. At Warmington and at Grantham, the two porches of either church are nearly opposite each other, and project approximately from the centre of the walls of the aisles. Where the porch has been pushed eastward in this way, the west end of the aisle seems to have been occupied by one or more chapels. There are indications of this at Warmington; while, in the neighbouring church of Tansor, where the porch is in the usual place, but the aisle has been lengthened somewhat to the west, there was certainly an altar west, as well as east, of the porch. There was at least one chantry chapel west of the south porch at Grantham. The south porch at Ludlow covers the wall of the third bay of the aisle from the west: here there were two chapels in the western part of the aisle. There was another chapel at the west end of the north aisle. It can hardly be proved that the position of porches was actually planned with this use of the aisles in view; but there can be no doubt that advantage was frequently taken of the s.p.a.ce thus added to the aisle.

CHAPTER V

THE AISLED PARISH CHURCH

II. TRANSEPTS AND CHANCEL

- 58. The aisled nave, with its usual appendages of porch and tower, has now been described at length. Before we proceed to the development of the chancel, the transepts or transeptal chapels of the parish church invite discussion. The distinction between true transepts, in churches with central towers, and the transeptal chapels which are nothing more than northern and southern extensions of the aisles, has been made already; and it has been seen that the cruciform plan with central tower reached a very full state of perfection during the twelfth century.

Further dignity was given to some cruciform churches by the addition of aisles to the transepts. St Mary Redcliffe at Bristol, the plan of which is that of a large collegiate or cathedral rather than a parish church, has transepts with eastern and western aisles: there is no central tower, but the transepts form a definite cross-arm to the church, which was designed with regard to the central point formed by the crossing of a longitudinal and a transverse axis. There are few churches in England as beautiful as that of Melton Mowbray, with its aisled transepts and tower above the crossing: had the chancel only been planned on a larger scale and with aisles, the unrivalled beauty and dignity of St Mary Redcliffe might have been approached here. The cruciform plan with central tower is the most n.o.ble of all church plans, when carried out by builders with large ideas. Churches like Ludlow, Nantwich, Holy Trinity and St John's at Coventry, St Mary's at Beverley, excite an admiration which is the natural result of the fact that the plan, instead of straggling in the ordinary way from east to west, is brought to a focus beneath the central tower.

[Ill.u.s.tration: Fig. 14. Plan of 13th century church: west tower, south porch, unequal transeptal chapels.]

- 59. Apart, however, from the tower above the crossing, the transept had a value of its own. It gave additional room for the side altars of the church. The transeptal chapels at Worth allowed of greater width for the chancel arch: the altars, which naturally would have stood against the wall on either side of the chancel arch, could be placed within these excrescences from the north and south walls of the church, and the central s.p.a.ce was thus left clear. This method of extension of the church by adding north and south chapels to the nave was pursued throughout the middle ages. The thirteenth century plan of Acton Burnell is virtually identical with the tenth or eleventh century plan of Worth. In aisled churches, such transeptal additions are simply outgrowths of the aisle walls, and were not necessarily planned with any regard to the s.p.a.cing of the arcades of the nave. They may, of course, be placed symmetrically at the east end of the aisles, the width of each chapel corresponding to the width of the arch of the arcade which is opposite its opening. Thus Exton church in Rutland, rebuilt about the beginning of the thirteenth century, has north and south transeptal chapels whose width is that of the eastern bay of each arcade. A transverse arch was thrown across each aisle at its junction with the adjacent chapel. Here the chapels form quasi-transepts in perfect union with the design of nave and aisles. Symmetrical plans in which it is clear at a glance that the transeptal chapels are developments of the aisles, and have no necessary relation to the nave, are those of Kegworth in Leicestershire, rebuilt in the fourteenth century, and Aylsham, Cawston, and Sall in Norfolk, which belong to the fifteenth century. But even more obvious than these are the plans in which transeptal chapels have been thrown out at different periods, or even at one and the same period, without the least regard to symmetry. A small aisleless nave at Stretton in Rutland received a north aisle about the beginning of the thirteenth century. Soon after, the eastern part of the side walls was taken down, and chapels built out to north and south. The width of the south chapel was determined by that of the old chancel arch, which was rebuilt between the chapel and the nave, there being no aisle on that side. The north chapel, on the other hand, was formed simply by returning the wall of the aisle northward, and throwing a transverse arch across the aisle from the wall above the arcade. Its width corresponds roughly with that of the south chapel, but has no correspondence with that of the adjacent bay of the arcade. Examples of this form of growth of plan, dictated by convenience and the necessity of the moment, are common in every part of England.

- 60. It is quite clear that the transeptal chapel, being nothing more than an excrescence from the wall of a nave or aisle, is a feature which may be treated with some freedom. Its width and length are dependent upon the convenience and will of the builders. The north chapel of the aisleless church of Clapton-in-Gordano, Somerset, is entered by an arch in the east part of the north wall: the chapel itself, however, extends some distance westward, so that its longer axis is parallel to the longer axis of the nave. The south chapel, again, at Lowick in Northamptonshire has its longer axis from east to west, although its roof is at right angles to that of the adjacent aisle. Externally, its transeptal character is apparent; internally, it has the appearance of an additional south aisle. A chantry was founded in this chapel in 1498.

Very often, where special chantry chapels were built, they took the position of transeptal chapels. Cases in point are the late Gothic chantry chapels in All Saints and St Lawrence's at Evesham. Such chapels may obviously be lengthened westward, like the chapel at Clapton-in-Gordano, so that they become additional aisles. The Milcombe chapel at Bloxham in Oxfordshire, the Greenway aisle at Tiverton in Devonshire, and the side chapels of the north and south aisles at St Andrew's, Plymouth, and Plympton St Mary are the logical outcome of the habit of adding transeptal chapels to the plan. Two transeptal chapels of the ordinary type are found in other Devonshire churches rebuilt in the fifteenth century, as at East Portlemouth: the Kirkham chapel at Paignton, famous for its carved stone-work, is transeptal. From this it is but a step to the chapels at Plymouth and Plympton, with their longer axes from east to west: while the aisle at Tiverton (1517) develops naturally, in the churches of Cullompton (1526) and Ottery St Mary (before 1530), into a vaulted aisle the full length of the nave. At Bloxham, on the other hand, the Milcombe chapel, which extends from the east wall of the south aisle as far as the porch, was probably grafted upon an earlier and smaller transeptal chapel. A comparison with the neighbouring church of Adderbury shows that the fabric of the transeptal chapels at Adderbury is largely of the twelfth century. The north chapel at Bloxham is, in its present state, much later; but the similarity of plan to that of Adderbury leads to the justifiable conclusion that it was rebuilt on old foundations, and that there was a similar south chapel. About 1290 the aisles at Bloxham were widened, and a beautiful arcade of two bays was built at the east end of the north aisle, between it and the north chapel. Within the next few years, the aisles at Adderbury were also widened, and arcades similar to that at Bloxham, though coa.r.s.er in detail, were built at the east end of either aisle.

The projection of the transeptal chapels from the side walls was now very slight; and, in the fifteenth century, the projection of the south chapel at Bloxham was absorbed by the building of the Milcombe chapel, between which and the south aisle an arcade of two bays was made. There is more intrinsic interest in this gradual development of plan than in the Devonshire plans we have noticed, which are all due to fifteenth century rebuildings; and the mutual influence exercised throughout the middle ages by two neighbouring churches like Bloxham and Adderbury gives us an insight into the progress of local art which the energy of fifteenth century masons in certain districts has somewhat obscured.

From the arrangement of the south transept at Adderbury, there appear to have been two altars in each of the chapels.

- 61. Transeptal chapels occasionally appear in unusual positions. For example, at Brans...o...b.. in south Devon, there is a tower between nave and chancel. There are, however, no transepts; but transeptal chapels are built out from the walls of the aisleless nave, west of the tower. These chapels appear to be enlargements of earlier transeptal chapels; while the tower seems to have been built over the chancel of the earlier church. Heckington church in south Lincolnshire was rebuilt in the fourteenth century. The nave has aisles with transeptal chapels, very regular and symmetrical in plan, but is continued beyond the opening of the transeptal projections by an aisleless bay, east of which comes the chancel arch. At Bottesford in north Lincolnshire, where much rebuilding was done in the thirteenth century, the transeptal chapels open from the bay east of the chancel arch. In the case of Heckington, the earlier church was probably cruciform: when the rebuilding came to pa.s.s, the ground plan of the western portion of the church was kept, while the chancel was built on an extended plan, and the site of the western part of the old chancel thrown into the nave. The case of Bottesford is probably accounted for in the opposite way: the site was not enlarged eastwards, but the chancel was lengthened by the absorption of the eastern part of the old nave.

- 62. There are a number of cases in which transeptal chapels have been kept from an earlier cruciform plan, in which they may have formed true transepts. The fine church of Oundle, whose western tower and spire already have been mentioned as built about 1400, has very fully developed transeptal chapels. The nave and aisles, and the greater part of the chapels, are, in their present state, work of the thirteenth century; but the eastern bay of the present nave was entirely remodelled about 1350, when a clerestory was added. This bay had evidently been designed to carry a central tower: the nave arcades stop west of it, and there is a thick piece of wall between them and the arches opening from it into the chapels. These arches and the chancel arch were entirely reconstructed at the time just mentioned. The western arch, however, was removed, and an original crossing was thus converted into a bay of the nave. Whether there ever was a central tower is, of course, an uncertain point; but the building of a west tower on a new site not many years after this reconstruction is a fact which makes the previous existence of a central tower probable. The removal of a central tower would be due to one of two causes. Either its supports were weak, or it blocked up the s.p.a.ce between nave and chancel too much. The central tower of Petersfield in Hampshire was taken down; but its east wall still remains between nave and chancel. However, if there are cases in which a central tower was removed, and a west tower built, there are probably more in which a central tower was planned, and then abandoned. Campsall church, near Doncaster, has unmistakable signs of a projected cruciform plan with a central tower, and has a regular crossing with transepts. But it is probable that the builders changed their minds before the nave was finished; and, although they doubtless left the arches, which were intended to bear their tower, for a later generation to remove and rebuild, they went westward and built a tower at the other end of the nave. This tower was finished towards the end of the third quarter of the twelfth century. The builders of Newark church, who were peculiarly susceptible to after-thoughts, apparently planned a central tower in the later part of the twelfth century. It is difficult to explain otherwise the slender cl.u.s.ters of shafts which project into the nave from the first pier west of the chancel arch on either side. Such piers were hardly capable of bearing the weight of a tower; and so the builders must have thought. Early in the thirteenth century, they began the present west tower, the first stage of a rebuilding which, with long intervals, continued into the sixteenth century. The final step by which the church reached its present plan was the addition of a transeptal chapel to either aisle, opposite the site which, more than three centuries before, had been chosen for the piers of the abandoned central tower.

[Ill.u.s.tration: Fig. 15. St Mary's, Beverley: arcades of quire and S.

transept, from S.W.]

- 63. Even in strictly cruciform churches, transepts were sometimes treated with a freedom which was more appropriate to the transeptal chapel. It is not unusual to find one transept longer than the other, as at Felmersham in Bedfordshire. Here, however, the transepts are not only of different lengths, but the south transept is loftier, as well as shorter, than the north, which is little more than a chapel-like excrescence from the tower. At Witney in Oxfordshire both transepts are of great projection, but the north transept is slightly longer than that on the south. Both have considerable traces of thirteenth century work; but, in the fourteenth century, the north transept was lengthened by an addition divided into two stories, the upper of which was a chapel, while the lower was probably a vaulted bone-hole. The south transept was also lengthened; and a chapel was built, projecting from its east wall near the south end. Both transepts have western aisles: that of the north transept, which stops short of the two-storied extension, contained an altar near the north end. There are traces of at least three other altars in the transepts, so that there was excellent reason for their somewhat unusual projection. At St Mary's, Beverley, an eastern aisle was added to the south transept in the fifteenth century, to provide more room for altars. The north transept already had a large chapel of two stages upon its eastern side, so that the plan was treated unsymmetrically. The tower of St Mary's at Stafford rests on heavy piers and narrow arches, and is flanked by north and south transepts. However, while the south transept, of good thirteenth century work, is rather small and short, the north transept was rebuilt with great magnificence in the fourteenth century, and its internal effect is that of a large side chapel rather than a transept. Aisled transepts are never common, even in large churches. Instances in which a transeptal chapel is aisled are even less common. The aisled south chapel at Medbourne in Leicestershire has been mentioned in an earlier chapter. Oakham and Langham churches in Rutland have large transeptal chapels with western aisles: the north chapel at Langham was removed in the fifteenth century, when the aisles of the nave were widened.

- 64. Reference has also been made to those plans in which the side walls of a tower between chancel and nave have been pierced with arches, and quasi-transepts have been constructed. This is very noticeable at Almondsbury in Gloucestershire, where the transeptal chapels, turned at a later date into burial-places for two local families, are very large and roomy. The cross-plan of Burford church in Oxfordshire was formed in this way, early in the thirteenth century. Plans like this, in which the chapels grow out of the central s.p.a.ce, instead of being planned from the first in relation to it, are imperfectly cruciform; but are highly characteristic of the irregular methods of development pursued by the builders of medieval parish churches.

- 65. Towers above transeptal chapels are not uncommon. The two transeptal towers at Ottery St Mary in Devon were doubtless copied from the arrangement at Exeter cathedral: there was an altar against the east wall of each chapel. The tower at Coln St Aldwyn, Gloucestershire, rises above a south chapel projecting from an aisleless nave. This addition was made in the fifteenth century. At Duddington in Northamptonshire the ground floor of the tower virtually forms, in its present state, an eastward extension of the south aisle parallel to the western part of the chancel: the original plan was probably similar to the present plan of Coln St Aldwyn. The n.o.ble church of Whaplode had transeptal chapels projecting from the east end of either aisle: the thirteenth century tower is above the south chapel. At Clymping in Suss.e.x the arrangement is very peculiar. The church, which is almost entirely of the thirteenth century, has north and south transeptal chapels, and only a south aisle to the nave. The tower, which is at the end of the south chapel, is earlier than the rest of the building, but is clearly in its original position.

- 66. The early progress of Gothic art in parish churches was marked by a general lengthening of chancels, a.n.a.logous to that elongation of the eastern arm which is characteristic of cathedrals and monastic churches.

This may be seen very clearly at Iffley, near Oxford, and Avening in Gloucestershire, where vaulted chancels of the twelfth century were lengthened in the thirteenth century by an eastern bay. Sometimes, as at St Mary's, Shrewsbury, where successive generations of builders were very faithful to the remains of earlier work, the old sedilia of a twelfth century chancel have been left in place. But, as a rule, the enlargement of the chancel implied an entire reconstruction, or the entire transformation of old work by the insertion of new windows or b.u.t.tresses. From the end of the twelfth century onwards, the normal chancel of the parish church has a length which is from a half to two-thirds of the length of the nave, the nave being slightly broader than the chancel. This is the case with most of those Norfolk churches, which may be regarded as the ideal examples of parish church planning.

Room was in this way secured both for the altar and the quire stalls, for which the ordinary rectangular chancel offered a very restricted s.p.a.ce.

- 67. Sometimes a new chancel encroached upon the nave. This happened at Skipwith in Yorkshire, where the church underwent some alteration about the middle of the fourteenth century. The new chancel was made of the same width as the nave; and apparently the old chancel arch was entirely removed, and its site, with the part of the nave immediately west of it, made into an extra bay of the chancel. No new chancel arch was built.

One of the most curious and perplexing instances, in which additional westward room has been given to the chancel, and there is no structural division between chancel and nave, is at Tansor in Northants. The perplexity which arises here is due to the plentiful re-use of old work by the builders, the presence of which in unexpected places makes the history of the building a nearly insoluble puzzle. The church reached its present length about 1140, when probably the Saxon nave was left as the west part of a church, which was now of the same width the whole way through, and had no chancel arch. Some forty years later, narrow aisles of three bays were added to the nave; and, about the same time, a transeptal chapel may have been thrown out from the south wall, immediately east of the south aisle. As the church stands on southward sloping ground, there seems to have been no room for another chapel on the north side. In the thirteenth century, the aisles were lengthened eastwards, to flank the western part of the chancel. The builders moved back the eastern responds of the old arcades to the points from which the lengthened arcades were to start. They set themselves, however, a difficult problem when they reserved a s.p.a.ce at the end of the north aisle for a sacristy, and set the respond on the west side of this narrow bay. Their north aisle thus consisted of five bays and a very narrow eastern bay for the sacristy. On the south side no s.p.a.ce corresponding to the sacristy was marked out, although the eastern respond was placed in a line with the east side of the opening of the sacristy. The number of bays on the south side had to be five, as there was no room for six. The result is that the pillars of the arcades, with the exception of those of the two bays furthest west, which were left unaltered, are not opposite each other. In the meantime, the old transeptal chapel was left standing between a south aisle and a short south chapel of the chancel. About 1300, the aisle and chapel seem to have been widened to the full length of the transeptal chapel, and thus a broad south aisle was formed. In this plan, the chancel proper projects for some distance east of the aisles; but, for ritual purposes, the eastern part of the nave, corresponding to the eastern bay of the north aisle and the sacristy bay beyond, forms, and has formed since the twelfth century, a western extension of the chancel.

- 68. The addition of aisles to chancels was an even more gradual process than the addition of aisles to naves; and, as a rule, the aisles were at first mere chapels. Chancel aisles or chapels of twelfth century date are not very common in smaller churches. But a plan like that at Melbourne, where the apsidal chapels east of the transepts flank the chancel very closely, leads naturally to the provision of chapels communicating directly with the chancel. The logical consequence of such a plan is seen at Oundle, at the close of the twelfth century, where rectangular chapels were built along the north and south walls of the western part of the chancel. The walls were pierced with broad, low arches, and arches were built between the chapels and the transepts. The chapels, in this instance, are at the back of the quire stalls; and a long projecting piece of aisleless chancel was left beyond them, to which, in the fifteenth century, a large northern vestry was added. This plan, where both chancel chapels were added at much the same time and on the same scale, is symmetrical. But, as a rule, chancel chapels were built just when they were needed. At Arksey, near Doncaster, where, as at St Mary's, Shrewsbury, the walls of late twelfth century transepts have been largely preserved inside the church in spite of many alterations, the chancel is a long aisleless twelfth century building east of a central tower. Towards the end of the thirteenth century, the north chancel wall was pierced, and a narrow chapel built, which was one bay shorter than the chancel itself. In the fourteenth and fifteenth centuries the nave was enlarged, and the south aisle was widened to the full length of the south transept. A south chapel was added to the chancel: its outer wall was continued from the south wall of the transept, and carried eastwards for a little distance beyond the east wall of the chancel. Thus chancel, south chapel, and north chapel, are all of three different lengths and breadths, the south chapel being the longest and widest. When the south chapel was built, a considerable portion of the old chancel wall was left untouched on its north side. It is obvious that the methods of building employed in such additions were those which have been described in connexion with the addition of aisles to a nave. It is no uncommon thing to enter, as at Tamworth, a chancel aisle or chantry chapel, and find substantial remains of the old outer wall of the chancel, which has been pierced with one or more arches of communication.

- 69. As the relative dates and proportions of chancel chapels vary so greatly, it is obvious that in many cases only one will be found. We frequently meet with churches which have only one aisle to the nave; but these are for the most part small buildings, and one aisle usually, in larger buildings, presupposes another, although symmetry of proportion need not be expected. However, many important churches have one chancel chapel, and no more. Raunds in Northamptonshire, and Leverington in Cambridgeshire, have south, but not north, chapels. Stanion in Northamptonshire, and Hullavington in Wiltshire, have north, but not south chapels. In both these last cases, the chapels are simply continuations of the aisles, without a break or intermediate arch; and the chapel at Stanion is neither more nor less than a second chancel. As the dedication of Stanion church is to St Peter and St Paul, it is not unlikely that the prominence given to the north chapel may be due to the provision of altars for both saints. The same consideration may have influenced the building of the church at Wisbech, which is also dedicated to St Peter and St Paul. Here, the twelfth century chancel had a south chapel; but when, at the end of the thirteenth century, the chancel was lengthened, the south chapel was also enlarged into what is practically a second chancel. Not only this, but the south aisle of the church was rebuilt on the scale of a second nave, a second south aisle was built out beyond it, and the whole church, which afterwards was enlarged towards the north and otherwise altered, was more than doubled in size.

- 70. Where chantry chapels are attached to one side or other of a chancel, their variations in size and plan are almost infinite. In the smallest examples, they are mere projections from the wall of the chancel, and little more than tomb recesses, such as the Cresacre chapel at Barnburgh, near Rotherham, or the Booth chapel on the south side of the chancel at Sawley in Derbyshire. The little north chapel of the chancel at Clapton-in-Gordano in Somerset may have served as a vestry.

At Brancepeth, near Durham, where there is a long chancel and an aisled nave with transeptal chapels, a south chantry chapel adjoins the east side of the south transeptal chapel, while a north chantry chapel forms an independent excrescence from the north wall, and is shut off from the chancel by a doorway. Brigstock in Northamptonshire has a very large north chancel chapel, which is virtually the eastern portion of a widened aisle: the south chapel, on the other hand, is of much later date, and is so small that there must have been room in it for an altar and little more. These smaller chantry chapels, like the beautiful south chapel at Aldwinkle All Saints, Northants, have often great architectural beauty of their own, and give great variety to the plan of the church. But chancel chapels are often larger and more important, like the fourteenth century south chapel at Leverton, near Boston, which is practically a separate building, separated from the chancel by a wall without an arcade, or like the very s.p.a.cious north chapel of the priory church at Brecon. The south chapel of the chancel at Berkeley in Gloucestershire, and the Clopton chapel at Long Melford in Suffolk, are shut off from the adjacent parts of the church, and belong to that cla.s.s of chantry chapel of which our cathedrals furnish many examples. In this case, the chapel is a small separate building, attached to the fabric of the church, but hardly forming an integral part of it.

- 71. 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 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. Moreover, when, in the fourteenth and fifteenth centuries, aisles were rebuilt or widened, there was always, as at Tansor, a tendency to decide the width of the aisle by the length of an existing transept or transeptal chapel, and to build the new outer wall flush with its gable wall. In this case, the aisle would be planned to communicate with the transept, and the west wall of the transept would have to be cut through. Where, as at Arksey, there was a central tower, the old transept was structurally necessary, and only as much of its masonry would be removed as was absolutely necessary. But we have seen that there were cases in which it was thought advisable to take down the central tower altogether, and build a new one at the west end, in which case the transepts were of no structural use; and there were far more cases in which the transeptal excrescences were merely projecting chapels. In these instances, the transept was felt to intervene awkwardly between the aisles of nave and chancel. Accordingly, its side walls and gabled roof were taken down, its end wall was remodelled, and it was placed under one roof with the adjacent aisles, in which it became merged. The cruciform plan was thus lost in certain churches, becoming absorbed in the ordinary elongated plan, with aisles to nave and chancel. Tamworth church in Staffordshire, and Marshfield in Gloucestershire, had twelfth century central towers.

These were removed or destroyed, at Tamworth in the fourteenth, at Marshfield in the fifteenth century, and the aisles and chancel chapels were widened to the original length, approximately, of the transepts.

The north and south arches of the crossing, however, remain in a blocked condition, and tell the tale of what has happened. Wakefield cathedral is another instance of a large parish church whose aisleless cruciform plan has gradually disappeared within the aisles, until the plan is--or was till the additions of a few years ago--an aisled rectangle, the origin of which is certainly not obvious at first sight. The transformations here described must clearly be understood not to apply to cruciform churches generally, but merely to churches which, with an originally cruciform plan, needed enlargement. Many handsome late Gothic buildings, like the churches of Rotherham and Chesterfield, or St Mary's at Nottingham, are regular cruciform churches with central towers; and sometimes, as at Newark, transeptal chapels were the latest of all additions to a church. But, where the transeptal chapel cramped necessary s.p.a.ce, it had to disappear. At St Margaret's, Leicester, the arches into the transeptal chapels remain; but the chapels themselves have entirely disappeared, and the arches merely form part of the arcade between the nave and its broad aisles.

- 72. The aim of restorers and rebuilders from the middle of the fourteenth century onwards was to convert the church into a rectangle with aisles. As we have seen, the chancel was constantly, in late Gothic churches, an aisleless projection from the main fabric; but, where it was aisled, the old haphazard methods were often abandoned, and the aisles were made of approximately equal size. The old distinction between nave and chancel, marked by the chancel arch, and the arches between chapels and aisles, begin to vanish. Where the chancel arch was kept, as at Long Sutton in Lincolnshire, new chancel chapels were prolonged westward on each side of the nave, in place of the old nave aisles. Fairford church in Gloucestershire was rebuilt towards the end of the fifteenth century, to contain the splendid stained gla.s.s which had just been acquired for it. A central tower was built on strong piers, as a concession to the old plan; but the aisles of the nave were continued on either side of the tower and along the sides of the chancel till within a bay of the east end. But, in a great many churches, not merely the aisles, but the nave and chancel also became continuous, without a structural division. This feature, common in East Anglia and the south-west of England, was the result of the importance of carved and painted wood-work in late Gothic churches. The rood screen, stretching across nave and aisles, appeared to full advantage, when unbroken by the chancel arch. 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. The arcades were rebuilt first, and the aisles followed. Many of these churches were doubtless enlarged from much smaller buildings. The south aisle at Ingham was probably the nave of the earlier church, to which the present nave, north aisle, chancel, and west tower, were added. The aisles in most cases continued at a uniform width eastward as chancel chapels. The north aisle at Worstead was continued by a two-storied sacristy to the level of the east wall of the chancel. The south aisle stops at a bay short of the east wall, leaving the end of the chancel projecting as an altar s.p.a.ce. Whether the chancel arch was retained or not, the projection of this aisleless eastern bay became a very general feature of the larger churches of East Anglia, and, in churches like Trunch, Southwold, and Clare, its tall side windows flood the s.p.a.ce with light The most striking example of this plan is at Long Melford in Suffolk, where there is no chancel arch, and the actual chancel projects beyond the aisles. Here, however, it is flanked on the north by the Clopton chapel, and on the south by the vestry, which forms a covered way to the detached lady chapel further east. The Long Melford plan, with a projecting altar s.p.a.ce, and without a chancel arch, is nearly universal in Cornwall, and is common in south Devon, where, as at Totnes, the aisles of the chancel are usually little more than comparatively short chapels, and sometimes, as at West Alvington, near Kingsbridge, extend only a bay beyond the screen. Its great advantages, apart from the display of wood-work which it permits, are the gain of internal s.p.a.ce permitted by the reduction of the solid portions of the building to a minimum, the additional light admitted by the same means, and the long uninterrupted clerestory which forms a wall of gla.s.s, with thin stone divisions, on each side of the upper part of the church.

- 73. The tendency to give the whole church aisles of equal width throughout, and extending along its whole length, was irresistible, especially in East Anglia. The church of North Walsham, rebuilt towards the end of the fourteenth century, is a great rectangle of three parallel divisions, with axes from east to west, and of nearly equal breadth. The chapel of St Nicholas at Lynn, rebuilt in 1419, is an even more striking example of the same design: in both cases the simple and somewhat monotonous plan is varied by the projection of a handsome south porch. At Lynn, the thirteenth century west tower, with a spire, was kept at the south-west corner of the aisled building. But the aisled rectangular plan, if it attained its highest development in East Anglia, had been reached already in other parts of England by gradual methods.

It has sometimes been fathered upon aisled naves of friary churches, which, like the great nave of the Black friars at Norwich, afforded s.p.a.ce for large congregations who came to hear sermons. But it is probable that the first churches which followed the course of expansion into the aisled rectangle were directly influenced by the example of the larger churches, like Lincoln, or, at a later date, York, which, in extending their eastern arms, aisled their quires, presbyteries, and eastern chapels, right up to the east wall. Thus the whole quire and chancel of Newark, with aisles extending their whole length, were planned in the early part of the fourteenth century, when the great eastern chapel, the "Angel Quire," of Lincoln, was little more than a generation old; and, although the progress of the work was long delayed, the eventual arrangement, in which the high altar was brought two bays forward from the east wall, and a s.p.a.cious chapel was left at the back, exactly recalls the arrangements of Lincoln and York.

Similarly the quire and chancel of the cruciform church of Holy Trinity at Hull are aisled to their full length: the arrangement, again, is that of a cathedral rather than a parish church. The influence of cathedral plans is clearly visible in St Mary Redcliffe at Bristol, and in the collegiate churches of Ottery St Mary and Crediton: but here the type followed is not that of Lincoln and York, but that more usual in the west and south of England at Hereford, Wells, Salisbury, Exeter, and elsewhere, where the aisles of the chancel are returned at the back of the east wall, and form a vestibule to a projecting aisleless lady chapel. This type of plan occurs outside its regular district at Tickhill, on the borders of Yorkshire and Nottinghamshire. But it is naturally exceptional, and would be used only where there was plenty of money and s.p.a.ce to spare: it demands for its full effect a considerable elevation, involving a large clerestory, and a church could seldom, if ever, be found whose original plan invited expansion on these lines. On the other hand, the aisling of the chancel throughout was simply the logical development of the ordinary church plan: if the plans of cathedrals may have suggested the later developments at churches like Newark or Hull, the simple aisled rectangle, with its three parallel divisions, and without any clerestory to distinguish the nave from the aisles--a plan remarkably characteristic of Cornwall--came into existence in the ordinary course of things, by an extension of the wings of the building until they flanked the whole of the nave and chancel.

- 74. The work done at Grantham in the fourteenth and fifteenth centuries ill.u.s.trates the purely natural development of the ordinary aisled church into the aisled rectangle. We have seen, in an earlier chapter, that, soon after 1300, the church consisted of an aisleless chancel, which was, however, overlapped at the west end by the north aisle of the nave; a nave, the north and south aisles of which followed different systems of s.p.a.cing; a western tower and spire, engaged within the aisles; and north and south porches. Several chantries were founded in the church during the fourteenth century. Not long after the Black Death of 1349, the south aisle was extended eastward to the whole length of the chancel. The south wall of the chancel was pierced by an arcade; and the lady chapel thus formed was raised upon a double crypt. It was not until more than a century later that the east wall of the north aisle was taken down, and the "Corpus Christi chancel" built out, continuing the north aisle without a break, and completely flanking the north wall of the chancel, through which an arcade was made. Here the reason of expansion was obviously the growth of chantry chapels; and the expansion follows the simplest course. The last addition to the fabric was the present vestry, in which was a chantry founded by the Hall family. This was built out at right angles to the north aisle, at the point where the old work was met by the later extension. Not until the church had been fully aisled, and afforded no further room for new altars, were chantry chapels usually added in the shape of excrescences from the fabric.

[Ill.u.s.tration: Fig. 16. Plans of Grantham church: (3) about 1350; (4) present day.]

- 75. One interesting feature in the planning of chancels, which has been much discussed, is worth a note. This is the fact that the axis of the chancel is frequently out of line with the axis of the nave, and generally has a slight northward inclination. Sometimes, as at Henbury in Gloucestershire, the inclination is very considerable, so that, from the west end of the church, nearly a quarter of the east wall is out of sight. Usually, the inclination is very slight; and there are many cases in which it is not northward, but southward--Sidbury and Salcombe Regis, near Sidmouth, Eastbourne in Suss.e.x and Aldwinkle St Peter in Northants, are cases in point. The popular explanation is that it symbolises the leaning of our Saviour's head upon the cross. Like most symbolical explanations, this is founded entirely upon fancy: the inclination is by no means confined to churches with cross plans, and, if it were, the theorists who argue from this standpoint confound the symbolism of the cross-plan between the cross itself and the Body which it bore. Others have sought to explain the phenomenon by suggesting that the orientation of the chancel followed the direction in which the sun rose on the morning of the patronal feast. A succession of visits at sunrise to churches on appropriate dates has not hitherto been attempted upon a comprehensive scale: if it were undertaken, it probably would be found that the sun, instead of rising obediently opposite the middle light of every east window, as the theory requires, would have many puzzling exceptions in reserve. The marked divergence of axis at Henbury is explained by the site of the building, which is on a gentle slope, with the axis of the nave distinctly from south-east to north-west. When the chancel was rebuilt in the thirteenth century, the masons kept as high upon the slope as they could, and so twisted the axis of the chancel a little further east. But we must also remember that, when chancels were lengthened and rebuilt, the work was done while the old chancels were still standing. The axis of the old chancel might be out of line with that of the nave. Unless very careful measurements were taken, the new east wall would probably be not quite parallel with the old east wall of the chancel. The side walls would be set out at right angles to the new east wall; and thus, when the new chancel was joined to the church, the divergence of axis would be more palpable than before. Or, for the same reason, a divergence of axis might be created for the first time. This seems to be the common sense explanation of a very common feature. But it must be added that there are instances in which the inclination is so decided that one is tempted to conclude either that the masons had very crooked sight, or that they were playing tricks with their perspective.

The feature, where it is at all marked, is something of a deformity. In our own day it has been introduced, apparently by design, into the plan of Truro cathedral. In medieval work, however, it will seldom be found in a chancel where no enlargement upon an early site has taken place; and it seems safe to conclude that, like so much else in medieval building which is irregular, it generally arises from the rebuilding of a fabric upon an enc.u.mbered site.
