CHAPTER VI

EARLY MEDIÆVAL OR ROMANESQUE ARCHITECTURE

Romanesque is the term applied to the architectural style of the early Middle Ages which prevailed from 1000 to 1200. It manifests considerable variety, according to locality, but at the same time a distinct character common to all branches, in that it embodied a return to certain Roman principles of construction, modified more or less by early Christian and Byzantine methods. It represents a stage in the evolution of Gothic architecture.

In such localities as the North of Italy and Provence, where Roman remains were plentiful, the Romanesque architecture made free use of antique columns and details. But in the Rhine Provinces, the North of France, and England, the lack of such materials and of skilful workmen encouraged the substitution of the pier for the column and caused the latter to be of simpler and in many cases ruder design. Necessity, in fact, compelled the adoption of new forms. Moreover, the desire of the Church to build permanently led to the use of stone in place of inflammable timber, especially in the building of the roofs. Accordingly, the use of vaulting was revived.

It was out of the application of these necessities of construction that the Romanesque style was evolved.

=Chevêt.=--The basilica plan became gradually modified. The nave and aisles were retained, but the chancel, with or without an apse, was carried farther back and the length of the transepts prolonged, so that in time the cruciform plan prevailed and acquired a symbolic significance. A special feature, gradually introduced, was the _chevêt_ which formed an _ambulatory_ around the sides of the choir and the semi-circle of the apse, and could be divided up into chapels dedicated to individual saints.

=Vaulting.=--In the earlier examples the nave was covered with a barrel-vault, the thrust of which was sustained in the first place by strengthening the nave walls by the omission of clerestory windows and, secondly, by the weight of barrel-vaults over the side aisles, their thrust, in turn, being sustained by thickening the outer walls and keeping the windows small. As a further reinforcement of the walls, projecting piers of masonry were built into them, which in time became features of the external decoration.

Gradually the barrel-vault was superseded by groin vaults; at first in the aisles and later over the nave as well. The groin vaulting over the aisles represented, as in Roman times, the intersection of two semicircular vaults. But since the nave was usually twice the width of the aisles, each of the nave bays would be oblong in plan. Accordingly two of these were included in one square bay, which took in two of the nave arches and corresponded to two aisle bays.

In some instances a shaft was carried up from the intervening pier on each side of the nave, supporting an intermediate transverse arch, so that the vaulting became sexpartite, or divided into six compartments. Whether the bay were six part or four part, the curve of all the groins--longitudinal, transverse, and diagonal--were semicircular. Accordingly, since the diagonals had a longer diameter, their curves rose above the others. This variation was met by giving a concave or domelike surface to each of the compartments, so that the workmen were able to adjust the stones to the differences of the curves.

=Rib-vaulting.=--While this was possible in the actual operation of placing the stones, it would have needed exceedingly delicate calculation to build timber centering adjusted in advance to these domelike surfaces. Moreover, the ponderousness of the dome nave vaulting had made the use of timber centering extremely costly, even where timber was plentiful; while in districts sparsely supplied the cost had been prohibitive. Consequently, the ingenuity of the builders devised a system of construction that reduced the need of timber centering to a minimum. This was the system known as rib-vaulting. Briefly, it consisted in spanning the space--longitudinally, transversely, and diagonally--with preliminary arches of masonry, thus forming a skeleton frame composed of what are known as ribs. Each of these ribs, being comparatively light, could be constructed on a single moveable and expansible piece of centering, called a _cerce_. When the ribs had set, they offered sufficient support to hold up the doming of the compartments while it was being laid.

To some extent this method of construction had been anticipated by the Romans who in certain instances built preliminary transverse ribs to act as permanent centerings of the vault, in the masonry of which the ribs were buried from sight. The reintroduction of this device and its further development, as above described, originated with the Lombard architects. This has been definitely determined by the English architect, Arthur Kingsley Porter, who has proved that the adoption of the system was prompted by the scarcity of wood in this locality. From Italy it spread to France, where it made its appearance in the Ile de France about 1100 or some 60 years after its adoption in Lombardy. It was at first employed purely as a necessary constructive expedient. Later its æsthetic possibilities came to be recognised, and the rib was developed by the Gothic architects into an element of great beauty, one of the characteristic features of the Gothic style.

Meanwhile, the use of vaulting by the Romanesque architects affected the character of the exterior. Mention has already been made of the masonry piers and the massive outside walls, pierced with small windows. For the further support of the vaulting-thrust towers were freely used. While in Italy the campanile was frequently detached from the main edifice, the towers in western and northern Romanesque churches became elements of prominence in the design. A pair frequently flanked the apse or four rose in the angles of the transepts and choir, while another pair, sometimes connected by a gallery, flanked the west end. A tower or dome might also surmount the _crossing_ of the nave and transepts. The towers were square, polygonal, or circular, divided into stories which were pierced with windows or embellished with arcades. They were crowned, like the nave and aisles, with an exterior sloping roof.

=Arcading.=--The arcading, which now became a favourite method of embellishing walls, was of two kinds; either being _open_ and permitting a passageway at the back of them, or with columns and arch mouldings attached to the wall, in the manner known as _blind arcading_. Another feature for strengthening as well as embellishing the wall was the use of masonry piers, which, resting on a plinth, projected from the wall only as far as the width of the cornice.

The exteriors, in fact, were no longer, as in early Christian churches, plain and almost barn-like, but assumed a varied picturesqueness that, however, was distinguished by a fine structural unity.

The arch, whether used in interior or exterior arcading or for the tops of doors and windows, was round; usually semicircular but occasionally _stilted_, the ends of the semicircle, that is to say, being raised on perpendicular lines. The later introduction of the pointed arch, it may be added, marks the transition from Romanesque to Gothic.

A characteristic development of the Romanesque style is the treatment of the doors and windows. The jambs or sides were carried back in a series of angular recesses, which were filled with small columns, whose abaci frequently united in a continuous moulding. In many cases the angular recesses of the jambs were prolonged around the arch.

The shafts of columns were decorated with fluting, which might be perpendicular, spiral, or barred like trellis-work. The capitals, except when antique Corinthian or Ionic columns were utilised, display a variety of embellishments, sometimes influenced by Byzantine examples, at other times representing an original working out of foliage motives, often rude in treatment, but, especially in the German work, vigorously decorative.

In the nave arcading, that is to say the series of arches on each side of the nave, the supports consisted of square piers, to the faces of which columns were attached. From two of them sprang the arches; a third supported the vaulting of the aisles, while a fourth was run up to a higher level to carry the vaulting of the nave.

=Italian Romanesque.=--Since the Romanesque style was coloured by the locality in which it appeared, it is necessary to study examples of it as they are found respectively in Italy, France, the Rhine Provinces, Spain, and England.

The Italian examples are conveniently subdivided into those of Northern, Central, and Southern Italy, or, more specifically, into the examples found in the districts north of the River Po, between the Po and the Tiber, and south of the latter. Of these the northern, to be considered later, are the most important, since they show, as we have noted, a more adventurous spirit in the matter of construction.

CENTRAL ITALY.--On the other hand, the builders of Central and Southern Italy still followed the simple basilican plan and retained the wooden roofs and, in consequence, clerestory windows. They raised, however, in many cases the level of the choir and placed a crypt chamber beneath it; which sometimes, as in =S. Miniato=, =Florence=, is open to the nave. But their inventiveness was displayed rather in the details of decoration. Central Italy being rich in marbles, the use of this material for embellishing the exterior and the interior with bands and geometric designs was carried to such a perfection as virtually to constitute a style. The most beautiful example is that of =S. Miniato=, where, too, the open woodwork of the roof has been restored to its original colouring of gold, green, blue, and red.

Another notable example of this developed style of decoration is presented at =Pisa=, in the group of buildings comprising the =Cathedral=, =Campanile=, and =Baptistry=. Here the façades are embellished--one might almost say composed, for the embellishment is applied so constructionally--with tiers of blind arcades or of open arcades of red and white marble. Those of the Baptistry received in the fifteenth century additions of Gothic canopies and traceries, but the front of the Cathedral and the circular Campanile retain their original character. The Baptistry, also circular in plan, is crowned by an outer hemispherical dome, through which penetrates a conical dome, which in the interior is supported on four piers and eight columns. The influence of Byzantine workmen is seen here as well as in the dome which crowns the crossing of the Cathedral. The transepts of the latter are prolonged beyond the basilica plan and terminate in apses.

The Campanile, which comprises eight stories embellished with arcading, is known as “The Leaning Tower,” since it inclines from the perpendicular about 13 feet in a height of 179, the greatest inclination being in the ground story, after which there is a slight recovery toward the perpendicular. It was begun in 1174 and completed in 1350. Vasari, the historian of Italian artists, writing some 200 years later, ascribes this lean to a settlement of the foundations. His explanation, though occasionally disputed, had been generally accepted, until the investigations of Professor William H. Goodyear, in 1910, established the fact that the inclination was intentional and provided for from the start of the work.

The tower is constructed of an exterior and an interior cylinder of masonry, the space between them being occupied by a spiral staircase. The steps of the latter were individually measured by Professor Goodyear, who has set forth the results in a Bulletin of the Brooklyn Institute of Arts and Sciences (Jan. 21, 1911). Briefly, they show that the treads of the steps vary in height and that they incline sometimes toward the inner wall, sometimes toward the outer. In this way they tend to create a balance of strains on the whole structure, which is further secured by increasing the strength of the inner walls, where the inclination is inward. That the careful calculation involved in this was not due to an afterthought or the necessity of remedying the effects of a settlement is proved by the fact that the inclination begins at the lowest step.

Why then was this design adopted? Professor Goodyear furnishes the answer in two subsequent Bulletins. Reduced to briefest terms it is this: The Pisan Baptistry also has an inclination from the normal, both perpendicular and horizontal. Thus, in the south façade there is an inclination in the horizontal lines of 2 feet 2 inches toward the choir. Meanwhile, the vertical lines of the west façade are perpendicular to this slope and, consequently, the front inclines inward toward the nave. And these are only instances of a number of asymmetries that occur throughout the cathedral, all of which are proved to have been intentional in the original design.

Further, the asymmetries at Pisa bear a close analogy to the numberless asymmetries that appear in S. Mark’s, Venice. The latter was built by Byzantine workmen, who therein followed the Oriental and the Hellenic dislike of formal mathematical regularity; and it is the Byzantine tradition again which in this respect, as in other details of decoration, domes and so forth, influenced the Romanesque group of buildings at Pisa. The order in which they were erected is, the Cathedral, Baptistry, and Campanile; so that in the Leaning Tower the architects merely carried the principle of asymmetry to an extreme pitch.

The influence of Pisa is found in =S. Michele= and =S. Martino= in =Lucca=, and in the =Cathedral of Pistoia=.

=South Italy.=--The most important SOUTHERN examples are found in Sicily, which in the tenth century was overrun by the Saracens, who in the following century were routed by the Normans. Consequently, the Saracenic influence is mingled with the Byzantine in the =Cathedral of Monreale=, near =Palermo=. The plan is basilican, with apses at the eastern ends of the nave and aisles. The choir is raised. The arches of the nave are pointed but not recessed, and are supported on columns, with Byzantine capitals. The aisle walls have a dado of white marble, twelve feet high, inlaid with borders, composed of porphyry, while the arches and clerestory of the nave are embellished with mosaics of biblical subjects, framed in arabesque borders. Of a sombre richness of colour, they display the Byzantine characteristic of severity of design, and impart to the interior a solemn grandeur.

=North Italy.=--It is in NORTHERN Italy, particularly in the Lombard churches, that the constructional development is most marked. For, while the plan remained basilican, only occasionally showing well-defined transepts, the architects devoted their energies to the problem of vaulting. A notable instance is =San Ambrogio, Milan=, which is an early example of the use of ribs in vaulting. The original church, erected in the ninth century, had wooden roofs; but in the rebuilding the nave was divided into four square bays, and immense piers were constructed to carry the diagonal, transverse, and longitudinal ribs.[6] Of corresponding massiveness are the transverse ribs, while to support the strain on the longitudinal ribs intermediate piers were introduced with an upper and a lower tier of double arches. These open into the two stories of the groin-vaulted aisles, which are given this treatment in order to act as buttresses to the thrust of the nave vaults. This compelled the omission of clerestory windows, thus adding to the sombreness of effect. Indeed the whole suggestion is one of ponderousness. It is the work of men experimenting with a new method of construction and intent for the present on achieving stability. The combination of the latter with dignity of height and the grace of lightness was yet to be developed in the Gothic treatment of the ribs.

The west end is approached by a narthex, opening into an arcaded atrium.

In the external decoration of the triple apse of the east end appears the rudimentary principle of the open arcade. The walls above the semi-dome and beneath the wooden exterior roof are crowned with a cornice, composed of arches supported upon corbels, the space between each being penetrated with a niche. This produces a series of deep shadows, in contrast with which the actual construction of the corbels assumes a lightness of effect. It was the preliminary step to the substitution of small detached columns for the corbels and the development of external arcading.

The open arcading in its full development appears in the west façade of =S. Michele=, =Pavia=, where it serves its characteristic purpose of constructively lightening the effect of the cornice of the roof. In this instance, as in many of the Lombard façades, the nave and aisles are included in a single gable, their interior separation being marked upon the exterior by masonry piers. Into this façade also, as in the older part of the exterior of =San Ambrogio=, are set pieces of earlier sculptured ornament. These exhibit a strange mingling of grotesque animals with Scandinavian interlaces and Byzantine features--a notable fact, since they correspond with the sculptured ornament found on some of the Rhenish churches. This suggests that Lombard workmen were employed in Germany and that they brought back with them some of the German taste for symbolism in ornament.

In the west front of the =Cathedral at Piacenza=, we find the same use of single gable and masonry piers, but the cornice arcade is supplemented by two horizontal bands, that mark the division of the aisles into two stories. Moreover, each of the three entrances is embellished with a two storied porch, supported on columns that rest on recumbent lions. Over the nave porch the wall is penetrated by a characteristically Romanesque feature--a _rose_ or _wheel_ window. A comparison of this façade with the elaborate ones of Central Italy illustrates the preference of the Lombard architects for organic disposition of decoration rather than decoration for the sake of decoration.

An important feature of North Italy is the Campanile. Intended, it is supposed, as a symbol of power, it is usually detached from the church, and square in plan. The walls are simply treated, being reinforced often with masonry piers, but interrupted with as few windows as possible, while the top is marked by one or two stories of arcaded windows and is crowned with a pyramidal or conical roof.

FRENCH ROMANESQUE

The map of France at the end of the tenth century shows the Royal Domain, the Ile de France, a dense forest with Orleans, the city of learning, at one end, and at the other, Paris, the city of the future--hemmed in on all sides by counties and duchies over which the Capetian King held little more than nominal suzerainty. For the purpose of architectural study these territories may be divided into north and south, on a line with the River Loire. Thus, to the north belong the Ile de France, Normandy, and Brittany; to the south, Provence, Aquitaine, Anjou, and Burgundy.

Everywhere the builders were intent upon the problem of vaulting; but were influenced in the south by local conditions. In Provence, for example, the seat of Roman civilisation, not only does classical influence appear in the details, but the vaulting is of the old Roman kind. =Notre Dame=, =Avignon=, is a well-known instance. And the barrel-vaulting was continued throughout the neighbouring Duchy of Aquitaine. Here, however, another influence intervened. The district had close commercial relations with Venice, Ravenna, and Byzantium, and it is reflected in the domical vaulting of many of the churches.

=S. Front=, =Perigeux=, for example, resembles S. Mark’s, Venice, in having the plan of a Greek cross, surmounted by five pendentives. The arches, however, are _pointed_; of great depth, resting on piers, pierced with passages. In the =cathedral= of the neighbouring city, =Angoulême=, a Latin cross is substituted for the Greek in plan. The aisleless nave is surmounted by three stone domes, roofed on the exterior. Over the crossing rises another dome, visible outside, which is raised upon a drum that is pierced with pointed windows, disposed in pairs. The southern transept is still crowned with a tower, its fellow to the north having been destroyed in 1568.

This building served as a model for the =Abbey of Fontevrault= in =Anjou=.

In Burgundy the most renowned of the numerous monastic establishments was the =Benedictine Abbey= of =Cluny=. Until the building of the present S. Peter’s, its abbey church was the largest and most magnificent in Christendom. The plan was a basilica with double aisles, the east end terminating in a _chevêt_ (shě-vay´); that is to say, an apse surrounded by a circular aisle, divided into chapels; in this case five in number. The nave was arcaded with pointed arches and spanned by an immense barrel vault. Groined vaulting, on the other hand, is supposed to have covered the aisles.

Groined vaulting takes the place of barrel-vaulting in the nave of the =Church of Vézelay=, and was also used in the ante-chapel, erected some thirty years later. But by this time the builders, in order to reduce the thrust, adopted a pointed section for the ribs--the first instance in France of the pointed groined vault, which was successfully developed later by the Gothic architects.

It is to be noted that the early vaulting, erected by the Clunisian architects, compelled the abandonment of the clerestory windows. The thrust of the great barrel vault of the nave was sustained either by high side aisles with either transverse or groined vaults over the bays, or by barrel vaults over the aisles, which in turn were supported by the massive outer walls. For the use of the flying buttress had not yet been adopted.

Meanwhile, the northern climate demanded the additional light provided by a clerestory, and the architects of Normandy applied themselves to the problem. It was to be solved later in Gothic architecture by the use of pointed groin vaulting, but, pending this discovery, a method of vaulting was employed which is known as sexpartite. For the square bay was crossed in the centre by another transverse arch, which, when cut by the two diagonals, produced a plan of six parts. This, however, necessitated two narrow skew vaults, meeting in the centre, which was awkward in appearance. The method is illustrated in =S. Etienne=, the great church of the =Abbaye-aux-hommes= and =La Trinité= of the =Abbaye-aux-Dames=, both in =Caen=. These and other churches of Normandy such as the Abbey church of =Mont-St. Michel=, are characterised by an adventurous spirit as well as logic of design, marking a distinct progress toward the Gothic.

ENGLISH ROMANESQUE OR NORMAN

The audacity and resourcefulness of the Norman builders found extensive opportunity after the conquest of England. But few remains survive of Anglo-Saxon architecture, and they suggest that the buildings were of a rude kind. They were constructed of rubble work, reinforced with engaged piers and ashlar masonry at the corners, arranged in what is called “long and short” courses. The columns were short, stumpy cylinders crowned with one or two square blocks, and the details of doorways and windows were roughly hewn with an axe, though in the case of certain belfry windows, jambs of baluster shape, seem to have been turned upon a lathe. The openings were either round-topped, suggesting a clumsy copy of the Roman style or else triangular, as if perpetuating a form of timber construction. The plan of the church appears to have been of the simplest, representing an oblong nave, separated by an arch from the smaller oblong of the chancel; the latter being lower than the nave and, on the inside, approached by two or three descending steps. The arrangement seems to have been derived from the example of the Celtic churches, as also was the habit of erecting towers, which, however, are not circular as in Ireland, but square without buttresses. One example of such a tower exists at =Earl’s Barton=, =Northamptonshire=, in which occur balustered windows.

The Normans, therefore, had a free field for their architectural enterprise and, while they immediately commenced the erection of castles to overawe the country, they also erected monasteries and cathedrals, designed to surpass in size and magnificence the ones in Normandy. While following the latter in a general way, the English examples were characterised, on the one hand, by a more massive and picturesque treatment, and, on the other, owing probably to the scarcity of skilled labour, by simpler and less refined details.

The capitals of columns, for instance, were usually of the cubic-cushion form, as may be seen in =S. John’s Chapel= in the =Tower of London=. The piers were often round and frequently clustered with columns, the round arches being recessed and framed with round mouldings. The latter, in the case of doorways and windows, were enriched with ornament carved in zig-zag, chevrons, billets, and beaked heads. The plan was apt to be longer than that of the French churches, and the elevations were proportionately lower. Vaulting was, for the present, confined to smaller churches and the side aisles of the larger; but the nave walls of the cathedrals were built sufficiently massive to support the vaulting which in some cases was subsequently added. The clerestory windows were set toward the outer part of the wall, the remaining space being occupied by a passageway, which, in front of the windows was screened from the nave by three arches.

While the Norman style, as the English-Romanesque is usually called in England, appears in many cathedrals, the character of it has been greatly modified by later additions. But the finest example still existing is that of =Durham=; next to which come =Peterborough= and portions of =Norwich=. The tower above the crossing, which became a distinction of English cathedrals and is so imposing a feature of =Durham=, was added much later. But the original nave (1096) is a remarkable example of massive Norman construction, the round piers having a diameter nearly equal to the span of the arches and being channelled with flutings and spirals. The vaulting was completed in 1133 and is said to be the earliest example of Norman vaulting in England. Another notable feature of Durham Cathedral is the so-called Galilee chapel, which, in imitation of the ante-chapel in Caen, takes the place of a porch at the west end. It was used by penitents.

At =Peterborough= the nave, only second to Durham as an example of Norman at its finest, is still covered with the original wooden ceiling, divided into lozenge shapes and painted. It is believed to be the oldest wooden roof in England. The Norman parts of =Norwich Cathedral= are the long, narrow, aisleless nave, the transepts, and the choir with its chevêt of chapels. =Ely=, again, has Norman nave and transepts; =Bristol=, a Norman chapter house; =Oxford=, nave and choir; =Southwell=, Norman nave, transepts, and towers; =Winchester=, transepts and towers; while =Worcester= has a Norman crypt, transepts, and circular chapter house. The last named is the only one of this design in England. Original Norman work is also to be found in the transepts at =Canterbury=, while the narrowness of its choir is due to the preservation of two Norman chapels.

In England the interior wall spaces and vaulting were decorated with paintings, for in this branch of decorative work the Normans found no scarcity of skill, since the Anglo-Saxon school of miniaturists, originally started by Celtic missionaries, had attained a high degree of proficiency, and now developed the principles of missal-painting into the larger and freer scope of mural decoration.

A good example of the small Norman church is that of =Iffley=, near Oxford. Especially interesting is the west front. In the larger examples this feature underwent change with the introduction of the pointed arch; but here is a distribution of the gabled end into three well defined and excellently proportioned stories, pierced, respectively, with a doorway, circular window, and an arcade of three windows. All are deeply recessed and enriched with characteristic moulding, and the effect, while a trifle barbaric, is vigorously decorative.

RHENISH ROMANESQUE

In the Rhenish Provinces is found the most fully developed Romanesque style, characterised by the fewest local differences. When, during the years 768-814, Charlemagne built his royal tomb-church, which with subsequent Gothic additions is now the =Cathedral= of =Aix-le-Chapelle=, he adopted the plan of S. Vitale in Ravenna and imported classic columns. Moreover, the Rhine Provinces possessed many remains of Roman architecture. Later they became closely allied by commerce with Northern Italy and seem to have employed the services of Lombard architects.

All these circumstances tended to make Rhenish Romanesque resemble that of Northern Italy. On the other hand, it developed a style more constructively adventurous, vigorous, and picturesque; while at the same time it was on the whole more systematically organised than the French. It was, however, about fifty years behind the latter in its development which began late and continued longer.

A typical example of the earlier period of Rhenish Romanesque is the =Cathedral at Worms= (1110-1200). Its design shows features that are characteristically Rhenish: an apse at both the west and east end, flanked in each case by two towers; the use of transepts at the west end as well as the east (the eastern ones being here omitted), the erection of octagonal lanterns over both crossings, and entrances on the north and south sides instead of the west.

The exterior exhibits a well-defined orderliness and picturesqueness. The walls are reinforced with projecting piers and pierced with deeply recessed, round-arch windows. Noticeable also is the effective use of corbel arcades beneath the gable ends of the roofs and in various string courses, while the richer emphasis of open arcades is applied with equal discretion and effectiveness. Another noteworthy feature in the towers is the use of dormers to embellish the conical or octagonal roof, which in effect are rudimentary spires.

Other early representative cathedrals are those of =Spires=, =Treves=, and =Mayence= while to the later period belongs the =Church of the Apostles=, =Cologne= (1220-1250). It offers a varied application of the same features in a singularly perfect design. The transepts and choir present a cluster of three apses round a low, octagonal lantern. The nave is short, twice the width of the side aisles and has western transepts and a square western tower. Especially fine are the exterior embellishments of the apses, consisting of two stories of blind arcading, surmounted by open arcades beneath the roof, while a corresponding sense of proportional dignity characterises the grouping of the eastern towers and lantern and the solitary distinction of the western tower. Here, as in three other examples of triapsal churches in =Cologne=--=S. Maria-in-Capitol=, =S. Martin=, and =S. Cunibert=--the domical vaulting is supported by squinches or pendentives.

The earliest example of nave vaulting is found in the =Cathedral of Mayence=, closely followed in the Cathedrals of =Spires= and =Worms= and the abbey church at =Laach=.

SPANISH ROMANESQUE

In Spain great impetus was given to cathedral building by the recapture of Toledo from the Moors in 1085. In architecture, as in painting, the Spaniards seem to have sought their artistic impulses from abroad, since the most important example of their early Romanesque style--the Cathedral of =Santiago de Compostello=--is a modified copy of =S. Sernin=, at =Toulouse=, =Aquitaine=. The plan is a Latin cross with aisles not only flanking the nave but also carried round the transepts and choir apse in the manner of the French chevêt. The aisles are groin-vaulted, while a lofty barrel vault covers the nave, and an octagonal lantern crowns the crossing.

A special feature of Spanish Romanesque, also derived apparently from Aquitaine, is the beauty of the dome, which covers the crossing, as in the old =Cathedral of Salamanca=, the =Collegiate Church= at =Toro= and the =Cathedral of Zamora=. They are circular in the interior and octagonal on the outside with large turrets in the angles of the octagon. The interior dome is carried upon pointed arches, between which and the spring of the vault, in the case of Salamanca, are two tiers of arcaded windows. For the admission of light the arrangement is excellent, while the general character of these domes, covered on the outside with a low, steeple-like roof of stone, is admirably monumental.

Another characteristic Spanish feature, met with in some churches, as for example, that of =San Millan=, =Sagovia=, is an open cloister, on the outside of the aisle, from which doors open into it.

Carved ornament was rather sparingly applied, and except in minute details suggests no Moorish influence.
