Temples.
There is perhaps nothing that strikes the inquirer into the architectural history of Rome more than the extreme insignificance of her temples, as compared with the other buildings of the imperial city and with some contemporary temples found in the provinces. The only temple which remains at all worthy of such a capital is the Pantheon. All others are now mere fragments, from which we can with difficulty restore even the plans of the buildings, far less judge of their effect. We have now no means of forming an opinion of the great national temple of the Capitoline Jove, no trace of it, nor any intelligible description, having been preserved to the present time. Its having been of Etruscan origin, and retaining its original form to the latest day, would lead us to suppose that the temple itself was small, and that its magnificence, if any, was confined to the enclosure and to the substructure, which may have been immense.
Of the Augustan age we have nothing but the remains of three temples, each consisting of only three columns; and the excavations that have been made around them have not sufficed to make even their plans tolerably clear.
The most remarkable was that of Jupiter Stator in the Forum, the beautiful details of which have been already alluded to and described. This temple was octastyle in front. It was raised on a stylobate 22 ft. in height, the extreme width of which was 98 ft., and this corresponds as closely as possible with 100 Roman ft. The angular columns were 85 ft. from centre to centre. The height of the pillars was 48 ft., and that of the entablature 12 ft. 6 in.[[165]] It is probable that the whole height to the apex of the pediment was nearly equal to the extreme width, and that it was designed to be so.
The pillars certainly extended on both flanks, and the temple is generally restored as peristylar, but apparently without any authority. From the analogy of the other temples it seems more probable that there were not more than eight or ten pillars on each side, and that the apse of the cella formed the termination opposite the portico.
The temple nearest to this in situation and style is that of Jupiter Tonans.[[166]] The order in this instance is of slightly inferior dimensions to that of the temple just described, and of very inferior execution. The temple, too, was very much smaller, having only six columns in front, and from its situation it could not well have had more than that number on the flanks, so that its extreme dimensions were probably about 70 ft. by 85.
The third is the Temple of Mars Ultor, of which a plan is annexed; for though now as completely decayed as the other two, in the time of Ant. Sabacco and Palladio there seem to have been sufficient remains to justify an attempt at restoration. As will be seen, it is nearly square in plan (112 ft. by 120). The cella is here a much more important part than is usual in Greek temples, and terminates in an apse, which afterwards became characteristic of all places of worship. Behind the cella, and on each side, was a lofty screen of walls and arches, part of which still remain, and form quite a new adjunct, unlike anything hitherto met with attached to any temple now known.

The next class of temples, called pseudo-peripteral (or those in which the cella occupies the whole of the after part), are generally more modern, certainly more completely Roman, than these last. One of the best specimens at Rome is the Temple of Antoninus and Faustina, a small building measuring 72 ft. by 120. There is also a very elegant little Ionic temple of this class called that of Fortuna Virilis; while the Ionic Temple of Concord, built by Vespasian, and above alluded to, appears also to have been of this class. So was the temple in the forum at Pompeii; but the finest specimen now remaining to us is the so-called Maison Carrée at Nîmes, which is indeed one of the most elegant temples of the Roman world, owing probably a great deal of its beauty to the taste of the Grecian colonists long settled in its neighbourhood. It is hexastyle, with 11 columns in the flanks, 3 of which stand free, and belong to the portico; the remaining 8 are attached to the walls of the cella. The temple is small, only 45 ft. by 85; but such is the beauty of its proportions and the elegance of its details that it strikes every beholder with admiration.

The date of this temple has not been satisfactorily ascertained. From the nail-holes of the inscription on the frieze it has been attempted to make out the names of Caius and Lucius Cæsar, and there is nothing in the style of its architecture to contradict this hypothesis. Even if the buildings in the capital were such as to render this date ambiguous, it would scarcely be safe to apply any argument derived from them to a provincial example erected in the midst of a Grecian colony. But for their evidence we might almost be inclined to fancy its style represented the age of Trajan.
The temple of Diana in the same city is another edifice of singular beauty of detail, and interesting from the peculiarity of its plan. Exclusive of the portico it is nearly square, 70 ft. by 65, and consists of a cella which is covered with a stone ribbed vault, the thrust of which is counteracted by smaller vaults thrown across two side passages or aisles which are, however, not thrown open to the cella. The columns in the cella are detached from the wall, which is singularly interesting as the origin of much which we find afterwards in Gothic work. (A somewhat similar arrangement is found in the small temple at Baalbec (Woodcut No. [197]) where, however, the peristyle occupies the position and serves the same purpose as the aisles at Nîmes, viz., to resist the thrust of the vault over the cella.)

Throughout this building the details of the architecture are unsurpassed for variety and elegance by anything found in the metropolis, and are applied here with a freedom and elegance bespeaking the presence of a Grecian mind even in this remote corner of the Empire. Another interesting feature is the porch. This was supported by four slender columns of singularly elegant design, but placed so widely apart that they could not have carried a stone entablature. It is difficult to guess what could have been the form of the wooden ones; but a mortice which still exists in the walls of the temple shows that it must have been eight or ten feet deep, and therefore probably of Etruscan form (Woodcut No. [167]); though it may have assumed a circular arched form between the pillars.[[167]]

Another peculiarity is, that the light was introduced over the portico by a great semicircular window, as is done in the Buddhist caves in India; which, so far as I know, is the most perfect mode of lighting the interior of a temple which has yet been discovered.
Not far from the Colosseum, in the direction of the Forum, are still to be seen the remains of a great double temple built by the Emperor Hadrian, and dedicated to Venus and Rome, and consisting of the ruins of its two cells, each about 70 ft. square, covered with tunnel-vaults, and placed back to back, so that their apses touch one another. These stand on a platform 480 ft. long by 330 wide; and it is generally supposed that on the edge of this once stood 56 great columns, 65 ft. in height, thus moulding the whole into one great peripteral temple. Some fragments of such pillars are said to be found in the neighbourhood, but not one is now erect,—not even a base is in its place,—nor can any of its columns be traced to any other buildings. This part, therefore, of the arrangement is very problematical, and I should be rather inclined to restore it, as Palladio and the older architects have done, with a corridor of ten small columns in front of each of the cells. If we could assume the plan of this temple to have been really peripteral, as supposed, it must have been a building worthy of the imperial city and of the magnificence of the emperor to whom its erection is ascribed.
More perfect and more interesting than any of these is the Pantheon, which is undoubtedly one of the finest temples of the ancient world. Externally its effect is very much destroyed by its two parts, the circular and the rectangular, being so dissimilar in style and so incongruously joined together. The portico especially, in itself the finest which Rome exhibits, is very much injured by being prefixed to a mass which overpowers it and does not harmonise with any of its lines. The pitch, too, of its pediment is perhaps somewhat too high, but, notwithstanding all this, its sixteen columns, the shaft of each composed of a single block, and the simple grandeur of the details, render it perhaps the most satisfactory example of its class.

The pillars are arranged in the Etruscan fashion, as they were originally disposed in front of three-celled temples. As they now stand, however, they are added unsymmetrically to a rotunda, and in so clumsy a fashion that the two are certainly not part of the same design and do not belong to the same age. Either it was that the portico was added to the pre-existing rotunda, or that the rotunda is long subsequent to the portico. Unfortunately the two inscriptions on the portico hardly help to a solution of the difficulty. The principal one states that it was built by M. Agrippa, but the “it” may refer to the rotunda only, and may have been put there by those who in the time of Aurelius[[168]] repaired the temple which had “fallen into decay from age.” This hardly could, under any circumstances, be predicated of the rotunda, which shows no sign of decay during the last seventeen centuries of ill-treatment and neglect, and may last for as many more without injury to its stability, but might be said of a portico which, if of wood, as Etruscan porticoes usually were, may easily in 200 years have required repairs and rebuilding. From a more careful examination on the spot, I am convinced that the portico was added at some subsequent period to the rotunda. If by Agrippa, then the dome must belong to Republican times; if by Severus it may have been, as is generally supposed, the hall of the Baths of Agrippa.[[169]] Altogether I know of no building whose date and arrangements are so singular and so exceptional as this. Though it is, and always must have been, one of the most prominent buildings in Rome, and most important from its size and design, I know of no other building in Rome whose date or original destination it is so difficult to determine.

Internally perhaps the greatest defect of the building is a want of height in the perpendicular part, which the dome appears to overpower and crush. This mistake is aggravated by the lower part being cut up into two storeys, an attic being placed over the lower order. The former defect may have arisen from the architect wishing to keep the walls in some proportion to the portico. The latter is a peculiarity of the age in which I suppose this temple to have been remodelled, when two or more storeys seem to have become indispensable requisites of architectural design. We must ascribe also to the practice of the age the method of cutting through the entablature by the arches of the great niches, as shown in the sectional part of the last woodcut. It has already been pointed out that this was becoming a characteristic of the style at the time when the circular part of this temple was arranged as it at present appears.
Notwithstanding these defects and many others of detail that might be mentioned, there is a grandeur and a simplicity in the proportions of this great temple that render it still one of the very finest and most sublime interiors in the world, and the dimensions of its dome, 145 ft. 6 in. span by 147 in height, have not yet been surpassed by any subsequent erection. Though it is deprived of its bronze covering[[170]] and of the greater part of those ornaments on which it mainly depended for effect, and though these have been replaced by tawdry and incongruous modernisms, still nothing can destroy the effect of a design so vast and of a form so simply grand. It possesses moreover one other element of architectural sublimity in having a single window, and that placed high up in the building. I know of no other temples which possess this feature except the great rock-cut Buddhist basilicas of India. In them the light is introduced even more artistically than here; but, nevertheless, that one great eye opening upon heaven is by far the noblest conception for lighting a building to be found in Europe.
Besides this great rotunda there are two other circular temples in or near Rome. The one at Tivoli, shown in plan and elevation in the annexed woodcuts (Nos. [192] and [193]), has long been known and admired; the other, near the mouth of the Cloaca Maxima, has a cell surrounded by twenty Corinthian columns of singularly slender proportions. Both these probably stand on Etruscan sites; they certainly are Etruscan in form, and are very likely sacred to Pelasgic deities, either Vesta or Cybele.

Both in dimensions and design they form a perfect contrast to the Pantheon, as might be expected from their both belonging to the Augustan age of art: consequently the cella is small, its interior is unornamented, and all the art and expense is lavished on the external features, especially on the peristyle; showing more strongly than even the rectangular temple the still remaining predominance of Grecian taste, which was gradually dying out during the whole period of the Empire.
It is to be regretted that the exact dates of both these temples are unknown, for, as that at Tivoli shows the stoutest example of a Corinthian column known and that in Rome the slenderest, it might lead to some important deductions if we could be certain which was the older of the two. It may be, however, that this difference of style has no connection with the relative age of the two buildings, but that it is merely an instance of the good taste of the age to which they belong. The Roman example, being placed in a low and flat situation, required all the height that could be given it; that at Tivoli, being placed on the edge of a rock, required as much solidity as the order would admit of to prevent its looking poor and insecure. A Gothic or a Greek architect would certainly have made this distinction.
One more step towards the modern style of round temples was taken before the fall of the Western Empire, in the temple which Diocletian built in his palace at Spalato. Internally the temple is circular, 28 ft. in diameter, and the height of the perpendicular part to the springing of the dome is about equal to its width. This is a much more pleasing proportion than we find in the Pantheon; perhaps the very best that has yet been employed. Externally the building is an octagon, surrounded by a low dwarf peristyle, very unlike that employed in the older examples. This angularity is certainly a great improvement, giving expression and character to the building, and affording flat faces for the entrances or porches; but the peristyle is too low, and mars the dignity of the whole.[[171]]

To us its principal interest consists in its being so extremely similar to the Christian baptisteries which were erected in the following centuries, and which were copies, but very slightly altered, from buildings of this class.
