Basilicas.
Like the study of all modern history, that of Christian architecture commences with Rome; and not, as is sometimes supposed, where the history of Rome leaves off, but far back in the Empire, if not, indeed, almost in the Republic.
As has already been pointed out, the whole history of the art in Imperial Rome is that of a style in course of transition, beginning with a purely Pagan or Grecian style in the age of Augustus, and passing into one almost wholly Christian in the age of Constantine.
At the first epoch of the Empire the temple architecture of Rome consisted in an external arrangement of columns, without arches or vaults, and was wholly unsuited for the purposes of Christian worship. Towards the end of the period it had become an internal architecture, making use of arches and vaults almost entirely to the exclusion of the columnar orders, except as ornaments, and became so perfectly adapted to Christian requirements, that little or no essential change in it has taken place from that time to the present day. A basilica of the form adopted in the first century after Constantine is as suited now as it was then to the forms and ceremonies of the Christian ritual.
The fact seems to be, that during the first three centuries after the Christian era an immense change was silently but certainly working its way in men’s minds. The old religion was effete: the best men, the most intellectual spirits of the age, had no faith in it; and the new religion with all its important consequences was gradually supplying its place in the minds of men long before it was generally accepted.
There is thus no real distinction between the Emilian or Ulpian basilicas and those which Constantine erected for the use of the early Christian republic. Nor is it possible, in such a series as the Pantheon, the Temple of Minerva Medica, and the Church of San Vitale at Ravenna, to point out what part really belongs to Pagan and what to Christian art.
It is true that Constantine fixed the epoch of completed transition, and gave it form and substance; but long before his time Paganism was impossible and a reform inevitable. The feeling of the world had changed—its form of utterance followed as a matter of course.
Viewed in this light, it is impossible to separate the early history of Christian art from that of Imperial Rome. The sequence is so immediate and the change so gradual, that a knowledge of the first is absolutely indispensable to a right understanding of the second.
One of the most remarkable facts connected with the early history of the Christian religion is, that neither its Founder nor any of His more immediate successors left any specific directions either as to the liturgical forms of worship to be observed by His followers, nor laid down any rules to be observed in the government of the newly established Church. Under these circumstances it was left almost wholly to those to whose care the infant congregation was entrusted to frame such regulations for its guidance as the exigencies of the occasion might dictate, and gradually to appoint such forms of worship as might seem most suitable to express the purity of the new faith, but at the same time with a dignity befitting its high mission.
In Judea these ceremonies, as might naturally be expected, were strongly tinctured with the forms of the Mosaic dispensation; but it appears to have been in Africa, and more especially in the pomp-loving and ceremonious Egypt, that fixed liturgies and rites first became an integral part of the Christian religion. In those countries far from the central seat of government, more liberty of conscience seems to have been attained at an early period than would have been tolerated in the capital. Before the time of Constantine they possessed not only churches, but a regularly established hierarchy and a form of worship similar to what afterwards obtained throughout the whole Christian world. The form of the government of the Church, however, was long unsettled. At first it seems merely to have been that the most respected individuals of each isolated congregation were selected to form a council to advise and direct their fellow-Christians, to receive and dispense their alms, and, under the simple but revered title of Presbyters, to act as fathers rather than as governors to the scattered communities by which they were elected. The idea, however, of such a council naturally includes that of a president to guide their deliberations and give unity and force to their decisions; and such we soon find springing up under the title of Bishops, or Presbyter Bishops, as they were first called. During the course of the second century the latter institution seems gradually to have gained strength at the expense of the power of the Presbyters, whose delegate the Bishop was assumed to be. In that capacity the Bishops not only took upon themselves the general direction of the affairs of the Church, but formed themselves into separate councils and synods, meeting in the provincial capitals of the provinces where they were located. These meetings took place under the presidency of the Bishop of the city in which they met, who thus assumed to be the chief or metropolitan. These formed a new presbytery above the older institution, which was thus gradually superseded—to be again surpassed by the great councils which, after the age of Constantine, formed the supreme governing body of the Church; performing the functions of the earlier provincial synods with more extended authority, though with less unanimity and regularity than had characterised the earlier institution.
It was thus that during the first three centuries of its existence the Christian community was formed into a vast federal republic, governed by its own laws, administered by its own officers, acknowledging no community with the heathen and no authority in the constituted secular powers of the State. But at the same time the hierarchy admitted a participation of rights to the general body of the faithful, from whom they were chosen, and whose delegation was still admitted to be their title to office.
When, in the time of Constantine, this persecuted and scattered Church emerged from the Catacombs to bask in the sunshine of Imperial favour, there were no buildings in Rome, the plan of which was more suited to their purposes than that of the basilicas of the ancient city. Though designed and erected for the transaction of the affairs of the heathen Empire, they happened to be, in consequence of their disposition and immense size, eminently suited for the convenience of the Christian Church, which then aspired to supersede its fallen rival and replace it by a younger and better institution.[[257]]
In the basilica the whole congregation of the faithful could meet and take part in the transaction of the business going on. The bishop naturally took the place previously occupied by the prætor or quæstor, the presbyters those of the assessors. The altar in front of the apse, where the pious heathen poured out libations at the commencement and conclusion of all important business, served equally for the celebration of Christian rites, and with the fewest possible changes, either in the form of the ceremonies or in the nature of the business transacted therein, the basilica of the heathen became the ecclesia or place of assembly of the early Christian community.
In addition, however, to the rectangular basilica, which was essentially the place of meeting for the transaction of the business of the Church, the Christian community early adopted a circular-formed edifice as a ceremonial or sacramental adjunct to the basilica. These were copied from the Roman tombs above described, and were in fact frequently built for the sepulchres of distinguished persons; but they were also used at a very early date as baptisteries, as well as for the performance of funereal rites. It does not appear that baptism, the marriage rites, or indeed any of the sacraments, were performed in the earliest ages in the basilica, though in after ages a font was introduced even into cathedrals. The rectangular church became ultimately the only form used. In the earlier ages, however, a complete ecclesiastical establishment consisted of a basilica, and a baptistery, independent of one another and seldom ranged symmetrically, though the tendency seems to have been to place the round church opposite the western or principal entrance of the basilica.
Though this was the case in the capital and other great cities, it was otherwise before the time of Constantine in the provinces. There the Christian communities existed as members of a religious sect long before they aspired to political power or dreamt of superseding the secular form of government by combination among themselves. In the remote parts of the Empire, in the earliest ages, they consequently built for themselves churches which were temples, or, in other words, houses of prayer, designed for and devoted wholly to the celebration of religious rites, as in the Pagan temples, and without any reference to the government of the community or the transaction of the business of the assembly. If any such existed in Italy or any other part of Europe, they either perished in the various persecutions to which the Christians were exposed when located near the seat of government, or they became hallowed by the memories of the times of martyrdom, and were rebuilt in happier days with greater magnificence, so that little or no trace of the original buildings now remains. So long, therefore, as our researches were confined to European examples, the history of Christian architecture began with Constantine; but recent researches in Africa have shown that, when properly explored, we shall certainly be able to carry the history of the early Christian style in that country back to a date at least a century before his time. In Syria and Asia Minor so many early examples have come to light that it seems probable that we may, before long, carry the history of Byzantine art back to a date nearly approaching that of the destruction of Jerusalem by Titus. It is, however, only so recently that the attention of ecclesiologists has been directed to the early examples of Christian architecture, that it is not yet possible to grasp completely the whole bearing of the subject; but enough is known to show how much the progress of research may modify the views hitherto entertained on the subject. Meanwhile too much attention can hardly be bestowed upon it, as it is by means of these early specimens of architectural art that we shall probably be best able to recover the primitive forms of the Christian liturgical observance.
One of the most ancient as well as interesting of the African churches which has yet been brought to light is that at Djemla. It is a simple rectangle, internally 92 ft. by 52, divided longitudinally with three aisles, the centre one of which terminates in a square cella or choir, which seems to have been enclosed up to the roof; but the building is so ruined that this cannot be known for a certainty. Though so exceptional, it is not difficult to see whence the form was derived. If we take such a plan, for instance, as that of the Maison Carré at Nîmes (Woodcut No. [187]), and build a wall round and put a roof over it, so as to make a building which was originally appropriated to external worship suitable for internal religious purposes, we should have exactly such a result as this. The cella must be diminished in extent, the pillars more widely spaced, and the front row converted into a wall in which the entrances would be usually placed. In this instance the one entrance, for some local reason, is lateral. The whole floor of the church is covered with a mosaic so purely classical in style of execution as to leave no doubt as to its early date.

A more common form is shown in the annexed woodcut, representing a small church at Announa, likewise in Algeria, about 45 ft. square, divided into three aisles and with a projecting apse. If we turn to the plan of the Temple of Mars Ultor (Woodcut No. [186]), we see at once whence this form was derived. It only requires the lateral columns to be brought slightly forward to effect the requisite change. When the building was to be used by a congregation, and not merely for display, the pillars would require to be more widely spaced.
A third form, from Ibrim in Nubia, shows the peculiarity of the apse being internal, which became very fashionable in the Eastern, though not so much so in the Western, churches, but still sufficiently so to make its introduction at this early age worthy of notice. The building is small, being only 57 ft. in length externally, but is remarkable for being built with something of the solidity of the Egyptian edifices among which it stands.
The next example which it may be necessary to quote to make this early form intelligible, is that of the church of St. Reparatus, near Orleansville—the ancient Castellum Tingitanum. According to an inscription still existing, it was erected A.D. 252,[[258]] but the second apse seems to have been added at a later date, to contain the grave of the saint. As it now stands, it is a double-apsed basilica 80 ft. long by 52 broad, divided into five aisles, and exhibiting on a miniature scale all the peculiarities of plan which we have hitherto fancied were not adopted until some centuries later. In this instance both the apses are internal, so that the side-aisles are longer than the centre one, no portion of them appearing to have been cut off for chalcidica or vestries, as was very generally the case in this age.
Another example, very much like this in arrangement, but on a larger scale, is found at Ermet, the ancient Hermonthis in Egypt. It measures over all 150 ft. by 90, and, if the plan in the great French work[[259]] is to be depended upon, is one of the most complete examples of its class. It has four ranges of columns, taken apparently from more ancient examples, and two apses with all the usual appurtenances.

Another two-aisled and single apse church, measuring 100 ft. by 65, called Dyer Abou Taneh, is represented in the same work;[[260]] but perhaps the most interesting of these churches is that known as the White Convent, situated on the edge of the Libyan Desert, above Siout. Externally it measures 215 ft. by 122, and is enclosed in a solid wall, surmounted by an Egyptian cornice, so that it looks much more like an ancient temple than a Christian church. Originally it had six doors, but all are now walled up, except one in the centre of the southern face; and above, a series of small openings, like loopholes, admitted light to apartments which apparently occupied the upper storey of lateral corridors. Light to the church was, of course, admitted through the clerestory, which could easily be done; and altogether as a fortified and mysterious abode, and place of worship of ascetics, it would be difficult to find a more appropriate example.
The age of this church is not very well ascertained; popularly it is, like so many others, ascribed to Sta. Helena, and the double aisles and triapsal arrangements are so like her church at Bethlehem, that there is no à priori improbability in the assumption. The plan, however, is more complicated and complete, and its external form bespeaks of troublous times, so that altogether it is probably a century or two (the monks say 140 years) more modern. Like other churches of its class, ancient materials have been so used up with those prepared at the time, that it is extremely difficult to ascertain the dates of such buildings. If, however, any one with sufficient knowledge would make a special study of these Egyptian churches, he would add one of the most interesting chapters to our history of early Christian Architecture, and explain many ritual arrangements whose origin is now involved in mystery; but for this we must wait. The materials are not at present available, all travellers in Egypt being so attracted by the surpassing interest of the Pagan remains of that country, as hardly to find time for a glance at the Christian antiquities.[[261]]

It was probably in a great measure owing to the influence of these provincial examples that the arrangements of the metropolitan basilicas were not long allowed to retain the form above described, though more was probably due to the change which was gradually taking place in the constitution of the governing body of the Church. The early arrangements of the Christian basilica, as copied from the secular forms of the Pagan places of assembly, soon became unsuited to the more exclusively religious purposes to which they were to be appropriated. The now dominant hierarchy of Rome soon began to repudiate the republicanism of the early days of the Church, and to adopt from the East the convenient doctrine of the absolute separation of the congregation into clergy and laity. To accommodate the basilica to this new state of things, first the apse was railed off and appropriated wholly to the use of the clergy: then the whole of the dais, or raised part in front of the apse on which the altar stood, was separated by pillars, called cancelli, and in like manner given up wholly to the clergy, and was not allowed to be profaned by the presence of the unordained multitude.
The last great change was the introduction of a choir, or enclosed space in the centre of the nave, attached to the bema or presbytery, as the raised space came to be called. Round three sides of this choir the faithful were allowed to congregate to hear the Gospels or Epistles read from the two pulpits or ambones, which were built into its enclosure, one on either side; or to hear the services which were read or sung by the inferior order of clergy who occupied its precincts.
The enclosure of the choir was kept low, so as not to hide the view of the raised presbytery, or to prevent the congregation from witnessing the more sacred mysteries of the faith which were there performed by the higher order of clergy.
Another important modification, though it entailed no architectural change, was the introduction of the bodies of the saints in whose honour the building was erected into the basilica itself, and depositing them in a confessional or crypt below the high altar.
There is every reason to believe that a separate circular building, or proper tomb, was originally erected over the grave or place of martyrdom, and the basilica was sanctified merely by its propinquity to the sacred spot. Afterwards the practice of depositing the relics of the saint beneath the floor became universally the rule. At about the same time the baptistery was also absorbed into the basilica; and instead of standing opposite the western entrance, a font placed within the western doors supplied its place. This last change was made earlier at Rome than elsewhere. It is not known at what exact period the alteration was introduced, but it is probable that the whole was completed before the age of Gregory the Great.
It was thus that in the course of a few centuries the basilicas aggregated within themselves all the offices of the Roman Church, and became the only acknowledged ecclesiastical buildings—either as places for the assembly of the clergy for the administration of the sacraments and the performance of divine worship, or for the congregation of the faithful.
None of the basilican churches, either of Rome or the provinces, possess these arrangements exactly as they were originally established in the fourth or fifth century. The church of San Clemente, however, retains them so nearly in their primitive form that a short description of it may tend to make what follows more easily intelligible. This basilica seems to have been erected in the fourth or fifth century over what was supposed to be the house in which the saint of that name resided. Recently a subterranean church or crypt has been discovered, which must of course be more ancient than the present remains.[[262]] Above this subterranean church stands the edifice shown in the accompanying plan (Woodcut No. [395]), nearly one-third less in size, being only 65 ft. wide internally, against 93 of the original church, though both were about the same length.

It is one of the few that still possesses an atrium or courtyard in front of the principal entrance, though there can be but little doubt that this was considered at that early age a most important, if not indeed an indispensable, attribute to the church itself. As a feature it may have been derived from the East, where we know it was most common, and where it afterwards became, with only the slightest possible modifications, the mosque of the Moslems. It would seem even more probable, however, that it is only a repetition of the forum, which was always attached to the Pagan basilica, and through which it was always entered; and for a sepulchral church at least nothing could be more appropriate, as the original application of the word forum seems to have been to the open area that existed in front of tombs as well as of other important buildings.[[264]]
In the centre of this atrium there generally stood a fountain or tank of water, not only as an emblem of purity, but that those who came to the church might wash their hands before entering the holy place—a custom which seems to have given rise to the practice of dipping the fingers in the holy water of the piscina, now universal in all Catholic countries.
The colonnade next the church was frequently the only representative of the atrium, and then—perhaps indeed always—was called the narthex, or place for penitents or persons who had not yet acquired the right of entering the church itself.
From this narthex three doorways generally opened into the church, corresponding with the three aisles; and if the building possessed a font, it ought to have been placed in one of the chapels on either the right or left hand of the principal entrance.
The choir, with its two pulpits, is shown in the plan—that on the left-hand side being the pulpit of the Epistle, that on the right of the Gospel. The railing of the bema or presbytery is also marked, so is the position of the altar with its canopy supported on four pillars, and behind that the throne of the bishop, with the seats of the inferior clergy surrounding the apse on either side.
Besides the church of San Clemente there are at least thirty other basilican churches in Rome, extending in date from the 4th to the 14th century. Their names and dates, as far as they have been ascertained, are set forth in the accompanying list, which, though not altogether complete, is still the best we possess, and is sufficient for our present purpose.[[265]]

Three of these, St. Peter’s, St. Paul’s, and the Lateran church, have five aisles, all the rest three, with only one insignificant exception, Sta. Balbina, which has no side-aisles. Two, St. Agnes and the old part of St. Lorenzo, have their side-aisles in two storeys, all the rest are only one storey in height, and the side-aisles generally are half the width of the central aisle or nave. Some of the more modern churches have the side-aisles vaulted, but of those in the list all except the two last have flat wooden ceilings over the central compartment, and generally speaking the plain ornamental construction of the roof is exposed. It can scarcely be doubted that originally they were ceiled in some more ornamental manner, as the art of ornamenting this new style of open construction seems to have been introduced at a later date.

Of the two last named, the Sta. Maria sopra Minerva might perhaps be more properly classed among the buildings belonging to the Italian Gothic style; but as it is the only one in Rome that has any claim to such a distinction, it is hardly worth while making it an exception to the rest. The San Agostino might also be called a Renaissance specimen. It certainly is a transitional specimen between the pillared and pilastered styles, which were then struggling for mastery. It may either be regarded as the last of the old race or the first of the new style, which was so soon destined to revolutionise the architectural world.
