Temple of Minerva Medica.
One important building remains to be mentioned before leaving this part of the subject. It commonly goes by the name of the Temple of Minerva Medica, though this is certainly a misnomer.[[189]] Recently it has become the fashion to assume that it was the hall of some bath; no building of that class, however, was known to exist in the neighbourhood, and it is extremely improbable that any should be found outside the Servian walls in this direction; moreover, it is wanting in all the necessary accompaniments of such an establishment.
It is here placed with the tombs, because its site is one that would justify its being so classed, and its form being just such as would be applicable to that purpose and to no other. It is not by any means certain, however, that it is a tomb, though there does not seem to be any more probable supposition. It certainly belongs to the last days of the Roman Empire, if indeed it be not a Christian building, which I am very much inclined to believe it is, for, on comparing it with the Baptistery of Constantine and the tomb of Sta. Costanza, it shows a considerable advance in construction on both these buildings, and a greater similarity to San Vitale at Ravenna, and other buildings of Justinian’s time, than to anything else now found in Rome.
As will be seen from the plan and section (Woodcuts Nos. [228] and [229]), it has a dome, 80 ft. in diameter, resting on a decagon of singularly light and elegant construction. Nine of the compartments contain niches which give great room on the floor, as well as great variety and lightness to the general design. Above this is a clerestory of ten well-proportioned windows, which give light to the building, perhaps not in so effective a manner as the one eye of the Pantheon, though by a far more convenient arrangement, to protect from the elements a people who did not possess glass. So far as I know, all the domed buildings erected by the Romans up to the time of Constantine, and indeed long afterwards, were circular in the interior, though, like the temple built by Diocletian at Spalato, they were sometimes octagonal externally. This, however, is a Polygon both internally and on the outside, and the mode in which the dome is placed on the polygon shows the first rudiments of the pendentive system, which was afterwards carried to such perfection by the Byzantine architects, but is nowhere else to be found in Rome. It probably was for the purpose of somewhat diminishing the difficulties of this construction that the architect adopted a figure with ten instead of eight sides.

This, too, is, I believe, the first building in which buttresses are applied so as to give strength to the walls exactly at the point where it is most wanted. By this arrangement the architect was enabled to dispense with nearly one-half the quantity of material that was thought necessary when the dome of the Pantheon was constructed, and which he must have employed had he copied that building. Besides this, the dome was ribbed with tiles, as shown in Woodcut No. [230], and the space between the ribs filled in with inferior, perhaps lighter masonry, bonded together at certain heights by horizontal courses of tiles where necessary.

Besides the lightness and variety which the base of this building derives from the niches, it is 10 ft. higher than its diameter, which gives to it that proportion of height to width, the want of which is the principal defect of the Pantheon. It is not known what the side erections are which are usually shown in the ground-plans, nor even whether they are coeval with the main central edifice. I suspect they have never been very correctly laid down.
Taking it altogether, the building is certainly, both as concerns construction and proportion, by far the most scientific of all those in ancient Rome, and in these respects as far superior to the Pantheon as it is inferior to that temple in size. Indeed there are few inventions of the Middle Ages that are not attempted here or in the Temple of Peace—but more in this than in the latter; so much so, indeed, that I cannot help believing that it is much more modern than is generally supposed.
As might be expected from our knowledge of the race that inhabited the European provinces of the Roman Empire, there are very few specimens of tombs of any importance to be found in them. One very beautiful example exists at St. Rémi, represented in the annexed woodcut (No. [231]). It can hardly, however, be correctly called a tomb, but is rather a cenotaph or a monument, erected as the inscription on it tells us, by Sextus and Marcus, of the family of the Julii, to their parents, whose statues appear under the dome of the upper storey. There is nothing funereal either in the inscription or the form, nor anything to lead us to suppose that the bodies of the parents repose beneath its foundation.
The lower portion of this monument is the square basement which the Romans always added to the Etruscan form of tomb. Upon this stands a storey pierced with an archway in each face, with a three-quarter pillar of the Corinthian order at every angle. The highest part is a circular colonnade, a miniature copy of that which we know to have once encircled Hadrian’s Mole.
The open arrangement of the arches and colonnade, while it takes off considerably from the tomb-like simplicity appropriate to such buildings, adds very much to the lightness and elegance of the whole. Altogether the building has much more of the aspiring character of Christian art than of the more solid and horizontal forms which were characteristic of the style then dying out.
Another monument of very singular and exceptional form is found at Igel, near Trèves, in Germany. It is so unlike anything found in Italy, or indeed anything of the Roman age, that were its date not perfectly known from the inscription upon it, one might rather be inclined to ascribe it to the age of Francis I. than to the latter days of the Roman Empire.
The form is graceful, though the pilasters and architectural ornaments seem somewhat misplaced. It is covered with sculptures from top to bottom. These, however, as is generally the case with Roman funereal monuments, have no reference to death, nor to the life or actions of the person to whom the monument is sacred, but are more like the scenes painted on a wall or ornamental stele anywhere. The principal object on the face represented in the woodcut is the sun, but the subjects are varied on each face, and, though much time-worn, they still give a very perfect idea of the rich ornamentation of the monuments of the last age of the Empire.

The Tour Magne at Nîmes is too important a monument to be passed over, though in its present ruined state it is almost more difficult to explain than any other Roman remains that have reached our times. It consists of an octagonal tower 50 ft. in diameter, and now about 120 ft. high. The basement is extended beyond this tower on every side by a series of arches supporting a terrace to which access was obtained by an external flight of steps, or rather an inclined plane. From the marks in the walls it seems evident that this terrace originally supported a peristyle, or, possibly, a range of chambers. Within the basement is a great chamber covered by a dome of rubble masonry, to which no access could be obtained from without, but the interior may have been reached through the eye of the dome. From the terrace an important flight of steps led upwards to—what? It is almost impossible to refrain from answering, to a cella, like those which crowned the tomb temples of Assyria. That the main object of the building was sepulchral seems hardly doubtful, but we have no other instance in Europe of a tomb with such a staircase leading to a chamber above it.
That Marseilles was a Phœnician and then a Phocian colony long before Roman times seems generally to be admitted, and that in the Temple of Diana (Woodcuts Nos. [188] and [189]) and in this building there is an Etruscan or Eastern element which can hardly be mistaken, and may lead to very important ethnographical indications when more fully investigated and better understood.
