Of the new names proposed by Mr. Sharpe “transitional” explains itself; and “geometrical, curvilinear, and rectilinear” refer to the characters of the window tracery at the different periods which they denote.[6]
The history of English Gothic proper may be said to begin with the reign of Henry II., coinciding very nearly with the commencement of the period named by Mr. Sharpe transitional (1145 to 1190), when Norman architecture was changing into Gothic. This history we propose now toconsider somewhat in detail, dividing the buildings in the simplest possible way, namely, into floors, walls, columns, roofs, openings, and ornaments. After this we shall have to consider the mode in which materials were used by the builders of the Gothic period,i.e.the construction of the buildings; and the general artistic principles which guided their architects,i.e.the design of the buildings.
It may be useful to students in and near London to give Sir G. Gilbert Scott’s list of striking London examples[7]of Gothic architecture (with the omission of such examples as are more antiquarian than architectural in their interest):—

Sculptured ornament from Westminster Abbey
THE excellences or defects of a building are more due to the shape and size of its floor and, incidentally, of the walls and columns or piers which inclose and subdivide its floor than to anything else whatever. A map of the floor and walls (usually showing also the position of the doors and windows), is known as a plan, but by a pardonable figure of speech the plan of a building is often understood to mean the shape and size and arrangement of its floor and walls themselves, instead of simply the drawing representing them. It is in this sense that the word plan will be used in this volume.
The plan of a Gothic Cathedral has been described, and it has been already remarked that before the Gothic period had commenced the dimensions of great churches had been very much increased. The generally received disposition of the parts of a church had indeed been already settledor nearly so. There were consequently few radical alterations in church plans during the Gothic period. One, however, took place in England in the abandonment of the apse.
At first the apsidal east end, common in the Norman times, was retained. For example, it is found at Canterbury, where the choir and transept are transitional, having been begun soon after 1174 and completed about 1184; but the eastern end of Chichester, which belongs to the same period (the transition), displays the square east end, and this termination was almost invariably preferred in our country after the twelfth century.
A great amount of regularity marks the plans of those great churches which had vaulted roofs, as will be readily understood when it is remembered that the vaults were divided into equal and similar compartments, and that the points of support had to be placed with corresponding regularity. Where, however, some controlling cause of this nature was not at work much picturesque irregularity prevailed in the planning of English Gothic buildings of all periods. The plans of our Cathedrals are noted for their great length in proportion to their width, for the considerable length given to the transepts, and for the occurrence in many cases (e.g.Salisbury, thirteenth century) of a second transept. The principal alterations which took place in plan as time went on originated in the desire to concentrate material as much as possible on points of support, leaving the walls between them thin and the openings wide, and in the use of flying buttresses, the feet of which occupy a considerable space outside the main walls of the church. The plans of piers and columns also underwent the alterations which will be presently described.[8]
Buildings of a circular shape on plan are very rare, but octagonal ones are not uncommon. The finest chapter-houses attached to our Cathedrals are octagons, with a central pier to carry the vaulting. On the whole, play of shape on plan was less cultivated in England than in some continental countries.
The plans of domestic buildings are usually simple, but grew more elaborate and extensive as time went on. The cloister with dwelling-rooms and common-rooms entered from its walk, formed the model on which colleges, hospitals, and alms-houses were planned. The castle, already described, was the residence of the wealthy during the earlier part of the Gothic period, and when, in the fourteenth and fifteenth centuries, houses which were rather dwellings than fortresses began to be erected, the hall, with a large bay window and a raised floor or dais at one end and a mighty open fire-place, was always the most conspicuous feature in the plan. Towards the close of the Gothic period the plan of a great dwelling, such as Warwick Castle (Fig.8), began to show many of the features which distinguish a mansion of the present day.
In various parts of the country remains of magnificent Gothic dwelling-houses of the fourteenth and fifteenth centuries exist, and long before the close of the perpendicular period we had such mansions as Penshurst and Hever, such palaces as Windsor and Wells, such castellated dwellings as Warwick and Haddon, differing in many respects but all agreeing in the possession of a great central hall. Buildings for public purposes also often took the form of a great hall. Westminster Hall may be cited as the finest example of such a structure, not only in England but in Europe.
The student who desires to obtain anything beyond the most superficial acquaintance with architecture must endeavour to obtain enough familiarity with ground plans, to be able to sketch, measure, and lay down a plan to scale and toreadone. The plan shows to the experienced architect the nature, arrangement, and qualities of a building better than any other drawing, and a better memorandum of a building is preserved if a fairly correct sketch of its plan, or of the plan of important parts of it, is preserved than if written notes are alone relied upon.
The walls of Gothic buildings are generally of stone; brick being the exception. They were in the transitional and Early English times extremely thick, and became thinner afterwards. All sorts of ornamental masonry were introduced into them, so that diapers,[9]bands, arcades, mouldings, and inlaid patterns are all to be met with occasionally, especially in districts where building materials of varied colours, or easy to work, are plentiful. In the perpendicular period the walls were systematically covered with panelling closely resembling the tracery of the windows (e.g., Henry VII.’s Chapel at Westminster).
The wall of a building ordinarily requires some kind of base and some kind of top. The base or plinth in English Gothic buildings was usually well marked and bold, especially in the perpendicular period, and it is seldom absent. The eaves of the roof in some cases overhang the walls, resting on a simple stone band, called an eaves-course, and constitute the crowning feature. In many instances,however, the eaves are concealed behind a parapet[10]which is often carried on a moulded cornice or on corbels. This, in the E. E. period, was usually very simple. In the Dec. it was panelled with ornamental panels, and often made very beautiful. In the Perp. it was frequently battlemented as well as panelled.
A distinguishing feature of Gothic walls is the buttress. It existed, but only in the form of a flat pier of very slight projection in Norman, as in almost all Romanesque buildings, but in the Gothic period it became developed.
The buttress, like many of the peculiarities of Gothic architecture, originated in the use of stone vaults and the need for strong piers at these points, upon which the thrust and weight of those vaults were concentrated. The use of very large openings, for wide windows full of stained glass also made it increasingly necessary in the Dec. and Perp. periods to fortify the walls at regular points.
A buttress[10]is, in fact, a piece of wall set athwart the main wall, usually projecting considerably at the base and diminished by successive reductions of its mass as it approaches the top, and so placed as to counteract the thrust of some arch or vault inside. It had great artistic value; in the feeble and level light of our Northern climate it casts bold shadows and catches bright lights, and so adds greatly to the architectural effect of the exterior. In the E. E. the buttress was simple and ordinarily projected about its own width. In the Dec. it obtained much more projection, was constructed with several diminutions (technically called weatherings), and was considerably ornamented. In the Perp. it was frequently enriched by panelling. The buttresses in the Dec. period are often setdiagonally at the corner of a building or tower. In the E. E. period this was never done.
The flying buttress[11]is one of the most conspicuous features of the exterior of those Gothic buildings which possessed elaborate stone vaults. It was a contrivance for providing an abutment to counterbalance the outward pressure of the vault covering the highest and central parts of the building in cases where that vault rested upon and abutted against walls which themselves were carried by arches, and were virtually internal walls, so that no buttress could be carried up from the ground to steady them.
A pier of masonry, sometimes standing alone, sometimes thrown out from the aisle wall opposite the point to be propped, formed the solid part of this buttress; it was carried to the requisite height and a flying arch spanning the whole width of the aisles was thrown across from it to the wall at the point whence the vault sprung. The pier itself was in many cases loaded by an enormous pinnacle, so that its weight might combine with the pressure transmitted along the slope of the flying arch to give a resultant which should fall within the base of the buttress. The back of such an arch was generally used as a water channel.
The forest of flying buttresses round many French cathedrals produces an almost bewildering effect, as, for instance, at the east end of Notre Dame;—our English specimens, at Westminster Abbey for example, are comparatively simple.
The gable and the tower are developments of the walls of the building. Gothic ispar excellencethe styleof towers. Many towers were built detached from all other buildings, but no great Gothic building is complete without one main tower and some subordinate ones.
In the E. E. style church towers were often crowned by low spires, becoming more lofty as the style advanced. In the Dec. style lofty spires were almost universal. In the Perp. the tower rarely has a visible roof.[12]
The artistic value of towers in giving unity coupled with variety to a group of buildings can hardly be exaggerated.
The positions which towers occupy are various. They produce the greatest effect when central,i.e.placed over the crossing of the nave and transepts. Lichfield, Chichester, and Salisbury may be referred to as examples of cathedrals with towers in this position and surmounted by spires. Canterbury, York, Lincoln, and Gloucester are specimens of the effectiveness of the tower similarly placed, but without a spire (Fig.12). At Wells a fine central octagon occupies the crossing, and is remarkable for the skill with which it is fitted to the nave and aisles internally. Next to central towers rank a pair of towers at the western end of the building. These exist at Lichfield with their spires; they exist (square-topped) at Lincoln, and (though carried up since the Gothic period) at Westminster.[13]Many churches have a single tower in this position (Fig.13).
The obvious purpose of a tower, beyond its serviceableness as a feature of the building and as a landmark, is to lift up a belfry high into the air: accordingly, almost without exception, church and cathedral towers are designed with a large upper story, pierced by openings ofgreat size and height called the belfry stage; and the whole artistic treatment of the tower is subordinate to this feature. It is also very often the case that a turret to contain a spiral staircase which may afford the means of access to the upper part of the tower, forms a prominent feature of its whole height, especially in the Dec. and Perp. periods.
Fig. 12.—Lincoln Cathedral. (Mostly Early English.)
In domestic and monastic buildings, low towers were frequently employed with excellent effect. Many castles retained the Norman keep, or square strong tower, which had served as the nucleus round which other buildings had afterwards clustered; but where during the Gothic period a castle was built, or rebuilt, without such a keep, one or more towers, often of great beauty, were always added. Examples abound; good ones will be found in the Edwardian castles in Wales (end of thirteenth century), as for example at Conway and Caernarvon.
The gable forms a distinctive Gothic feature. The gables crowned those parts of a great church in which the skill of the architect was directed to producing a regular composition, often called a front, or a façade. The west fronts of Cathedrals were the most important architectural designs of this sort, and with them we may include the ends of the transepts and the east fronts.
The same parts of parish churches are often excellent compositions. The gable of the nave always formed the central feature of the main front. This was flanked by the gables, or half-gables, of the aisles where there were no towers, or by the lower portions of the towers. As a rule the centre and sides of the façade are separated by buttresses, or some other mode of marking a vertical division, and the composition is also divided by bands of mouldings or otherwise, horizontally into storeys. Some of the horizontal divisions are often strongly marked, especially in the lower part of the building, where in early examples there is sometimes in addition to the plinth, or base of the wall, an arcade or a band of sculpture running across the entire front (e.g.east front of Lincoln Cathedral). The central gable is always occupied by a large window—or in early buildings a group of windows—sometimes two storeys in height. A great side window usually occurs at the end of each aisle. Below these great windows are introduced, at any rate in west fronts, the doorways, which, even in the finest English examples, are comparatively small. The gable also contains as a rule one or more windows often circular which light the space above the vaults.
Fig. 13.—St. Pierre, Caen, Tower and Spire. (Spire, 1302.)
Part of the art in arranging such a composition is to combine and yet contrast its horizontal and vertical elements.The horizontal lines, or features, are those which serve to bind the whole together, and the vertical ones are those which give that upward tendency which is the great charm and peculiar characteristic of Gothic architecture. It is essential for the masses of solid masonry and the openingsto be properly contrasted and proportioned to each other, and here, as in every part of a building, such ornaments and ornamental features as are introduced must be designed to contribute to the enrichment of the building as a whole, so that no part shall be conspicuous either by inharmonious treatment, undue plainness, or excessive enrichment.
Fig. 14.—House at Chester. (16th Century.)
During the transition the gable became steeper in pitch than the comparatively moderate slope of Norman times. In the E. E. it was acutely pointed, in the Dec. the usual slope was that of the two sides of an equilateral triangle: in the Perp. it became extremely flat and ceased to be so marked a feature as it had formerly been. In domestic buildings the gable was employed in the most effective manner, and town dwelling-houses were almost invariably built their gable ends to the street (Fig.14).
A very effective form of wall was frequently made use of in dwelling-houses. This consisted of a sturdy framework of stout timbers exposed to view, with the spaces between them filled in with plaster. Of this work, which is known as half-timbered work, many beautiful specimens remain dating from the fifteenth and following centuries (Figs.14and15), and a few of earlier date. In those parts of England where tiles are manufactured such framework was often covered by tiles instead of being filled in with plastering. In half-timbered houses, the fire-places and chimneys, and sometimes also the basement storeys, are usually of brickwork or masonry; so are the side walls in the case of houses in streets. It was usual in such buildings to cause the upper storeys to overhang the lower ones.
The columns and piers of a building virtually form portions of its walls, so far as aiding to support the weight of the roof is concerned, and are appropriately considered in connection with them. In Gothic architecture very little use is made of columns on the outside of a building, and the porticoes and external rows of columns proper to the classic styles are quite unknown. On the other hand the series of piers, or columns, from which spring the arches which separate the central avenues of nave, transepts and choir from the aisles, are among the most prominent features in every church. These piers varied in each century.[14]
The Norman piers had been frequently circular or polygonal, but sometimes nearly square, and usually of enormous mass. Thus, at Durham (Norman), oblong piers of about eleven feet in diameter occur alternately with round ones of about seven feet. In transitional examples columns of more slender proportions were employed either (as in the choir of Canterbury) as single shafts or collected into groups. Where grouping took place it was intended that each shaft of the group should be seen to support some definite feature of the superincumbent structure, as where a separate group of mouldings springs from each shaft in a doorway, and this principle was very steadily adhered to during the greater part of the Gothic period.[14]
Fig. 15.—Houses at Lisieux, France. (16th Century.)
Through the E. E. period groups of shafts are generally employed; they are often formed of detached shafts clustering round a central one, and held together atintervals by bands or belts of masonry, and generally the entire group is nearly circular on plan. In the succeeding century (Dec. period) the piers also take the form of groups of shafts, but they are generally carved out of one block of stone, and the ordinary arrangement of the pier is on a lozenge-shaped plan. In the Perp., the piers retain the same general character, but are slenderer, and the shafts have often shrunk to nothing more than reedy mouldings.
The column is often employed in Transitional and E. E. churches as a substitute for piers carrying arches. In every period small columns are freely used as ornamental features. They are constantly met with, for example, in the jambs of doorways and of windows.
Every column is divided naturally into three parts, its base, or foot; its shaft, which forms the main body; and its capital, or head. Each of these went through a series of modifications. Part of the base usually consisted of a flat stone larger than the diameter of the column, sometimes called a plinth, and upon this stood the moulded base which gradually diminished to the size of the shaft. This plain stone was in E. E. often square, and in that case the corner spaces which were not covered by the mouldings of the base were often occupied by an elegantly carved leaf. In Dec. and Perp. buildings the lower part of the base was often polygonal, and frequently moulded so as to make it into a pedestal.[15]
The proportions of shafts varied extraordinarily; they were, as a rule, extremely slender when their purpose was purely decorative, and comparatively sturdy when they really served to carry a weight.
The capital of the column has been perhaps the most conspicuous feature in the architecture of every age andevery country, and it is one of the features which a student may make use of as an indication of date and style of buildings, very much as the botanist employs the flower as an index to the genus and species of plants. The capital almost invariably starts from a ring, called the neck of the column. This serves to mark the end of the shaft and the commencement of the capital. Above this follows what is commonly called the bell,—the main portion of the capital, which is that part upon which the skill of the carver and the taste of the designer can be most freely expended, and on the top of the bell is placed the abacus, a flat block of stone upon the upper surface of which is built the superstructure or is laid the beam or block which the column has to support. The shape and ornaments given to the abacus are often of considerable importance as indications of the position in architectural history which the building in which it occurs should occupy.
The Norman capital differed to some extent from the Romanesque capitals of other parts of Europe. It was commonly of a heavy, strong-looking shape, and is often appropriately called the cushion capital. In its simpler forms the cushion capital is nothing but a cubical block of stone with its lower corners rounded off to make it fit the circular shaft on which it is placed, and with a slab by way of abacus placed upon it. In later Norman and transitional work the faces of this block and the edges of the abacus are often richly moulded. By degrees, however, as the transition to E. E. approached, a new sort of capital[16]was introduced, having the outline of the bell hollow instead of convex. The square faces of the Norman capital of course disappeared, and the square abacus soon (at least in this country) became circular, involving no smallloss of vigour in the appearance of the work. The bell of this capital was often decorated with rich mouldings, and had finely-designed and characteristic foliage, which almost always seemed to grow up the capital, and represented a conventional kind of leaf easily recognised when once seen.
In the Dec. period the capitals have, as a rule, fewer and less elaborate mouldings; the foliage is often very beautifully carved in imitation of natural leaves, and wreathed round the capital instead of growing up it. In the Perp. this feature is in every way less ornate, the mouldings are plainer, and the foliage, often absent, is, when it occurs, conventional and stiff. Polygonal capitals are common in this period.

Sculptured ornament from Westminster Abbey
THE openings (i.e.doors and windows) in the walls of English Gothic buildings are occasionally covered by flat heads or lintels, but this is exceptional; ordinarily they have arched heads. The shape of the arch varies at all periods. Architects always felt themselves free to adopt any shape which best met the requirements of any special case; but at each period there was one shape of arch which it was customary to use.
In the first transitional period (end of twelfth century) semicircular and pointed arches are both met with, and are often both employed in the same part of the same building. The mouldings and enrichments which are common in Norman work are usually still in use. In the E. E. period the doorways are almost invariably rather acutely pointed, the arched heads are enriched by a large mass of rich mouldings, and the jambs[17]have usually a series of small columns, each of which is intended to carry a portion of the entire group of mouldings. Large doorways are often subdivided into two, and frequently approachedby porches. A most beautiful example occurs in the splendid west entrance to Ely Cathedral. Other examples will be found at Lichfield (Fig.1) and Salisbury. It was not uncommon to cover doorways with a lintel, the whole being under an archway; this left a space above the head of the door which was occupied by carving often of great beauty. Ornamental gables are often formed over the entrances of churches, and are richly sculptured; but though beautiful, these features rarely attained magnificence. The most remarkable entrance to an English cathedral is the west portal of Peterborough—a composition of lofty and richly moulded arches built in front of the original west wall. A portal on a smaller scale, but added in the same manner adorns the west front of Wells. As a less exceptional example we may refer to the entrance to Westminster Abbey at the end of the north transept (now under restoration), which must have been a noble example of an E. E. portal when in its perfect state.
Fig. 16.—Lancet Window. (12th Century.)
The windows in this style were almost always long, narrow, and with a pointed head resembling the blade of a lancet (Fig.16). The glass is generally near the outside face of the wall, and the sides of the opening are splayed towards the inside. It was very customary to place these lancet windows in groups. The best known group is the celebrated one of “the five sisters,” five lofty single lights, occupying the eastern end of one of the transepts ofYork Minster. A common arrangement in designing such a group was to make the central light the highest, and to graduate the height of the others. It after a time became customary to render the opening more ornamental by adding pointed projections called cusps. By these the shape of the head of the opening was turned into a form resembling a trefoil leaf. Sometimes two cusps were added on each side. The head is, in the former case, said to be trefoiled—in the latter, cinqfoiled.
Fig. 17.—Two-light Window. (13th Century.)
Fig. 18.—Geometrical Tracery. (14th Century.)
When two windows were placed close together it began to be customary to include them under one outer arch, and after a time to pierce the solid head between them with a circle, which frequently was cusped, forming often a quatrefoil (Fig.17). This completed the idea of agroup, and was rapidly followed by ornamental treatment. Three, four, five, or more windows (which in such a position are often termed lights) were often placed under one arch, the head of which was filled by a more or less rich group of circles; mouldings were added, and thus rose the system of decoration for window-heads known as tracery. So long as the tracery preserves the simple character of piercings through a flat stone, filling the space between the window heads, it is known as plate tracery. The thinning down of the blank space to a comparatively narrow surface went on, and by and by the use of mouldings caused that plain surface to resemble bars of stone bent into a circular form: this was called bar tracery, and it is in this form that tracery is chiefly employed in England (Fig.18). Westminster Abbey is full of exquisite examples of E. E. window-tracery (temp. Henry III.); as, for example, in the windows of the choir, the great circular windows (technically termed rose-windows) at the ends of the transepts, the windows of the chapter-house. Last, but not least, the splendid arcade whichforms the triforium is filled with tracery similar in every respect to the best window tracery of the period (Fig.19).
Fig. 19.—The Triforium Arcade, Westminster Abbey. (1269.)
In the decorated style of the fourteenth century tracery was developed till it reached a great pitch of perfection and intricacy. In the earlier half of the century none save regular geometrical forms, made up of circles and segments of circles, occur; in other words, the whole design of the most elaborate window could be drawn with thecompasses, and a curve of contrary flexure rarely occurred. In the latest half of that period flowing lines are introduced into the tracery, and very much alter its character (Fig.20). The cusping throughout is bolder than in the E. E. period.
Fig. 20.—Rose Window from the Transept of Lincoln Cathedral. (1342-1347.)
In perpendicular windows spaces of enormous size are occupied by the mullions and tracery. Horizontal bars, called transoms, are now for the first time introduced, and the upright bars or mullions form with them a kind of stone grating; but below each transom a series of small stone arches forms heads to the lights below that transom, and a minor mullion often springs from the head of each of these arches, so that as the window increases in height, the number of its lights increases. The characterof the cusping changed again, the cusps becoming club-headed in their form (Fig.21).
Fig. 21.—Perpendicular Window.
Arches in the great arcades of churches, or in the smaller arcades of cloisters, or used as decorations to the surface of the walls, were made acute, obtuse, or segmental, to suit the duty they had to perform; but when there was nothing to dictate any special shape, the arch of the E. E. period was by preference acute[18]and of lofty proportions, and that of the Dec. less lofty, and its head equilateral (i.e.described so that if the ends of the base of an equilateral triangle touch the two points from which it springs, the apex of the angle shall touch the point of the arch). In the Perp. period the four centred depressed arch, sometimes called the Tudor arch, was introduced,and though it did not entirely supersede the equilateral arch, yet its employment became at last all but universal, and it is one of the especially characteristic features of the Tudor period.
The external and the internal covering of a building are very often not the same; the outer covering is then usually called a roof—the other, a vault or ceiling. In not a few Gothic buildings, however, they were the same; such buildings had what are known as open roofs—i.e.roofs in which the whole of the timber framing of which they are constructed is open to view from the interior right up to the tiles or lead. Very few open roofs of E. E. character are now remaining, but a good many parish churches retain roofs of the Dec., and more of the Perp. period. The roof of Westminster Hall (Perp., erected 1397) shows how fine an architectural object such a roof may become. The roof of the hall of Eltham Palace (Fig.22) is another good example. Wooden ceilings, often very rich, are not uncommon, especially in the churches of Norfolk and Suffolk, but greater interest attaches to the stone vaults with which the majority of Gothic buildings were erected, than to any other description of covering to the interiors of buildings.
The vault was a feature rarely absent from important churches, and the structural requirements of the Gothic vault were among the most influential of the elements which determined both the plan and the section of a mediæval church. There was a regular growth in Gothic vaults. Those of the thirteenth century are comparatively simple; those of the fourteenth are much richer and moreelaborate, and often involve very great structural difficulties. Those of the fifteenth are more systematic, and consequently more simple in principle than the ones which preceded them, but are such marvels of workmanship, and so enriched by an infinity of parts, that they astonishthe beholder, and it appears, till the secret is known, impossible to imagine how they can be made to stand.
