Roman Mosaics; Or, Studies in Rome and Its Neighbourhood

by Hugh Macmillan

The work of excavation was begun seventy-five years ago by the Duchess of Devonshire, who spent the last years of her life in Rome, and formed the centre of its brilliant society. Napoleon III., the late Emperor of the French, carried on the task thus auspiciously commenced, for the purpose of shedding light upon the parts of Roman history connected with Julius Cæsar, the hero of his book. In spite of much opposition from the Papal Government, the work of exhumation was continued in fits and starts after the French emperor had given it up; and ever since the Italian Government have taken the matter in hand, gangs of labourers under the directorship of the accomplished Signor Rosa have been more or less continually employed, with the result that almost the whole area has been laid bare from the Capitol to the Arch of Titus. The British Archæological Society of Rome has given valuable aid according to the funds in its possession, and the contributions sent from this country for the purpose. When first commenced, the changes caused by these excavations were regarded with no favourable eye by either the artists or the people of Rome. The trees were cut down, the mantle of verdure that for centuries had covered the spot—Nature's appropriate pall for the decay of art—was ruthlessly torn up, and great unsightly holes and heaps of débris utterly destroyed the picturesque beauty of the scene. But the loss to romance was a gain to knowledge; and now that the greatest part of the Forum has been cleared down to the ancient pavement, we are able to form a much more vivid and accurate conception of what the place must have been in the days of the empire, and are in a position to identify buildings which previously had been a theme for endless and violent disputes. It is a very interesting and suggestive coincidence that the Forum of Rome should have been thus disentombed at the very time that Italy rose from its grave of ages, and under a free and enlightened government, having its centre once more in the Eternal City, proved that it had inherited no small share of the spirit of the heroic past.

Let us go over in brief detail the various objects of interest that may now be seen in the centre of Roman greatness. Numerous sources of information exist which enable us to identify these monuments, and to form some idea of what they were in their prime. Among these may be mentioned coins and medals of the emperors, with representations upon them of buildings and sculptures in the Forum; a marble stone found at Ancyra, now Angouri in Phrygia, on which is a long inscription regarding the acts and achievements of Augustus, which is of the greatest value in determining the topography of the city; the bas-reliefs on the Arch of Constantine, and on the marble screens of Trajan, recently excavated in the Forum itself, giving a view of its north-western and south-eastern ends; and the remains of the antique marble plan of Rome, now preserved in the Capitoline Museum, originally affixed to the wall of the superb Temple of Rome, and discovered in fragments in 1867 in the garden of the monastery of SS. Cosma e Damiano. We also get most valuable help in the work of identification from the Itineraries of the middle ages—especially from that of the celebrated pilgrim from Einsiedlen, Zwingli's town in Switzerland—who visited Rome in the eighth century, and left his manuscript to his own abbey, where it may still be seen. A vast apparatus of learning has been accumulated from the works of ancient classic authors by the great scholars who have written on the historical localities and buildings of the Forum, from Donati to Becker. Nibby, Canina, Ampère, Bunsen, Plattner, and Uhrlich, in their magnificent works have supplied a mine of wealth from which most subsequent writers on the Forum have enriched their descriptions.

The direction of the Forum is nearly from north to south, trending a little from north-east to south-west. It is surprisingly small to have contained such a large number of buildings, and to have bulked so prominently in the eye of the world; its greatest length being only six hundred and seventy-one feet, and its greatest breadth about two hundred and two feet. Beginning at the north end, we see before us the vast mass of the ancient Capitol, the proudest symbol of the majesty of Rome, crowned with the great staring medieval structures of the Roman municipality, rising up into the campanile of Michael Angelo. Until of late years, this renowned building was completely buried beneath a huge mound of rubbish. Now that it has been removed, the venerable fabric stands out distinctly to view, and we behold the massive walls of the Treasury, the Record Office, and the Senate House. The lowest part, constructed of huge blocks of volcanic stones, was the Ærarium or Public Treasury, and is supposed to have been formed out of the original wall of the city of the Sabines, which surrounded the hill of Saturn, as the Capitoline Mount was originally called, long before Romulus laid the foundation of Rome. As the Roman army was paid in coppers, spacious cellars were required for storing the coin, and these were provided in the underground vaults of the Treasury, partially cut out of the volcanic rock of the Capitol, on which the building rests. Above the Treasury, on the second floor, we see the remains of the Doric portico of the Tabularium or Public Record Office, where the records of Rome, engraved upon bronze tablets, were kept. The place is now converted into an architectural museum, where all the most interesting sculptured fragments found in the Forum are preserved, and are exhibited by gaslight owing to the darkness. These buildings, it must be remembered, form the back of the Capitol fronting the Forum. Strictly speaking, they do not belong to the Forum, which should be traced only from their verge.

The view on the other side of the Capitol, where a gently-inclined staircase leads up from the streets to the piazza at the top, surrounded by the modern municipal buildings, raised upon the ancient substructures above described, is quite different. But the present aspect of the Capitol is quite disappointing to one who comes to it seeking for evidences of its former grandeur. There is no trace of the Temple of Jupiter Capitolinus, to which the triumphal processions of the Roman armies led up, gorgeous with all the attractions of marble architecture, and the richest spoils of the world, the most splendid monument of human pride which the world then contained. Probably its remains were used up in the construction of the gloomy old church of the Ara Coeli, which is supposed by most archæologists to stand upon its site. The Capitol, it may be remarked, was precisely similar to the moot-hill, or open-air court, which existed in our own country in primitive times, and where justice was administered at regular intervals. The tradition of this original use of it still clings to the place as a shadow from the past. The hill has always been appropriated for political purposes. It has continued from the earliest days to be a centre of secular as opposed to ecclesiastical authority. The Popes ceded it to the magistracy, whose municipal buildings now cover it, and placed the church of Ara Coeli—the only one ever built on the Capitoline Hill—under their protection. The place of execution was chosen conveniently near to this moot-hill, or seat of justice; and the criminal, when condemned, was speedily executed, by being hurled over the rock, just outside of the eastern rampart, which surrounded the settlement. We can thus easily understand the association of the Tarpeian Rock with the Capitoline Hill. They were as closely correlated as the moot-hill and the Gallow hill in our own country. The primitive method of execution derived a sanctity from its antiquity, and was continued far on into the most civilised times of the empire.

So densely crowded were the historical buildings and remarkable sites in that part of the Forum which lay immediately behind the Capitol, that it is almost impossible now to identify their position or remains. This spot forms the great battle-ground of the antiquaries, whose conclusions in many instances are mere guess-work. Below the medieval tower of the Capitol is a wide space paved with fragments of coloured marbles, and with indications of the ground-plan of a building. This is supposed to mark the site of the Temple of Concord, erected by the great general Camillus, after the expulsion of the Gauls, to perpetuate the concord between the plebeians and patricians on the vexed question of the election of consuls. It was placed beside the old meeting-place of the privileged families. From the charred state of some of its sculptures discovered on the spot, it is supposed to have been destroyed by fire. It was restored and enlarged a hundred and twenty years before Christ by the Consul Opimius immediately after the murder of Caius Gracchus. To the classical student it is specially interesting as the place where Cicero convoked the senate after the discovery of the Catiline conspiracy, for the purpose of fixing the punishment due to one of the greatest of crimes. Among the senators present on that memorable occasion were men of the highest political and philosophical renown, including Cæsar, Cato, and Cicero. They came to the conclusion that there was no such thing as retribution beyond the grave, no future state of consciousness, no immortality of the soul; consequently death was considered too mild a punishment for the impious treason of the conspirators; and a penalty, which should keep alive instead of extinguishing suffering, was advocated. We learn from this extraordinary argument, as Merivale well says, how utter was the religious scepticism among the brightest intellects of Rome only thirty-seven years before the coming of Christ. The very name of the temple itself, dedicated not to a divine being as in a more pious age, but to a mere political abstraction, a mere symbol of a compact effected between two discordant parties in the state, indicated how greatly the Romans had declined from their primitive faith.

But the most conspicuous of the ancient remains in this quarter, and the first to attract the notice of every visitor, is the Ionic portico of eight columns, called at first the Temple of Jupiter, and then of Vespasian, but now definitely determined to be the Temple of Saturn, for it is closely connected with the Ærarium, and the Ærarium is said by several ancient authors to have led into the podium of the temple by a doorway in its wall still visible. This temple is supposed to be of very early origin, and to have marked the site of an ancient Sabine altar to the oldest of the gods of Italy long before the arrival of the Romans. It was nearly entire so late as the fifteenth century; but its cella was ruthlessly destroyed shortly afterwards, and its marble ornaments used for making lime. The present group of pillars was so clumsily restored by the French at the beginning of this century that they are seen to differ from each other in diameter, and the frieze is composed of fragments that do not harmonise.

But the most remarkable monument of antiquity in this part is the marble triumphal Arch of Septimius Severus, which stands in front of the ruins of the Temple of Concord. It invaded the site of the republican Græcostasis, where foreign ambassadors waited for an audience of the senate, and occupied part of the area of the Comitium, whose original character was thereby destroyed; for it was erected at a time when men ceased to care for the venerable associations connected with the early history of their city. One gazes upon this monument of Roman power and pride with deep respect, for it has stood nearly seventeen centuries; and though rusty and sorely battered, and its sculptures much mutilated, it is still one of the most solid and perfect relics of imperial times. It was raised to commemorate the wars of Septimius Severus in Parthia and Arabia; and represents among its carvings the goddess Rome receiving the homage of the Eastern nations. It exhibits on its panels many scenes connected with his campaigns, the memory of which no humane man would have liked to perpetuate. On the upper part of the Arch is a large inscription in honour of the emperor and his two sons, Caracalla and Geta. The name of Geta, however, was afterwards erased by his brother when he had murdered him, and other words substituted. Marks of the erasure may still be seen perfectly distinct after all these centuries, and vividly recall the terrible associations of the incident. The dislike which Caracalla and Geta had for each other was so virulent that their father took them both with him to Britain, in order that they might forget their mutual animosity while engaged in active warfare. Septimius Severus died during this campaign at York, and his sons returned to Rome to work out soon after the domestic tragedy of which this Arch reminds us. On the top of the Arch there was originally a bronze group of a chariot and four horses, with the emperor and his sons driving it. But this was removed at an early date; and in the middle ages the summit of the Arch supported the campanile of the church of St. Sergius and Bacchus that was built up against its sides. A little to the left, the road passing under the Arch joins the Clivus Capitolinus which wound through the Forum, and led up to the great Temple of Jupiter on the Capitol. The pavement of this ancient road, which still exists, is formed of broad hexagonal slabs of lava, and is as smooth and as finely jointed at this day as when the triumphal processions of the victorious Roman generals used to pass over it.

At the western corner of the Arch of Severus are the scanty remains of a tall conical pyramid, about fifteen feet in diameter, which is identified as the Umbilicus Romæ, placed in the exact centre of old Rome. Not far from it stood the Milliarium Aureum, or Golden Milestone, on which were inscribed all the distances of roads without the walls. The Roman roads throughout the empire terminated at this point. With this central milestone was connected that admirable system of roads which the Romans constructed in our distant island; and it is a remarkable circumstance that the principal railway lines in England are identical with the general direction of the old Roman roads. The Antonine Way is now the Great Western Railway, and the Roman Watling Street, which ran diagonally across the country from Chester in the north-west to Dover in the south-east, is now replaced by the Dover, London, Birmingham, Grand Junction, Chester, and Crewe Railways. The reason of this union of ancient and modern lines of communication is obvious. The Romans formed their roads for the purpose of transporting their armies from place to place, and at certain distances along the roads a series of military stations were established. In course of time these stations became villages, towns, and cities such as Chester, Leicester, Lancaster, Manchester. Thus, strange as it may appear, the Milliarium Aureum of the Roman Forum has had much to do with the origin of our most ancient and important towns, and with the formation of the great lines of railway that now carry on the enormous traffic between them.

The exposed vaults immediately behind the Arch of Severus, bounding the Forum in this direction, are richly draped with the long, delicate fronds of the maidenhair fern. Shaded from the sun, it grows here in the crevices of the old walls in greater luxuriance and profusion than elsewhere in the city. There is something almost pathetic in this association of the frailest of Nature's productions with the ruins of the most enduring of man's works. Strength that is crumbling to dust and ashes, and tender beauty that ever clings to the skirts of time, as she steps over the sepulchres of power, have here in their combination a deep significance. The growth of the soft fern on the mouldering old stones seems like the sad, sweet smile of Nature over a decay with which she sympathises, but which she cannot share. The same feeling took possession of me when, wandering over the ruins of the Palaces of the Cæsars on a sunny February afternoon, I saw above the hoary masses of stone the rose-tinted bloom of almond-trees. Out of the gray relics of man's highest hour of pride, the leafless almond-rod blossomed as of old in the holy place of the Hebrew Tabernacle; and its miracle of colour and tenderness was like the crimson glow that lingers at sunset upon Alpine heights, telling of a glory that had long vanished from the spot.

Beneath these fern-draped vaults is the oldest prison in the world. The celebrated Mamertine Prison takes us back to the very foundation of the city. It was regarded in the time of the Cæsars as one of the most ancient relics of Rome, and was invested with peculiar interest because of its venerable associations. It consists of a series of vaults excavated out of the solid tufa rock, where it slopes down from the Capitoline Hill into the Forum, each lined with massive blocks of red volcanic stone. For a long time these vaults have been used as cellars under a row of tall squalid-looking houses built over them between the Via di Marforio and the Vicolo del Ghettarello; and the sense of smell gives convincing proof that where prisoners of state used to be confined, provisions of wine, cheese, and oil have been stored. The prison has recently passed into the possession of the British and American Archæological Society of Rome, which pays a certain rent to the Italian Government for its use. By this society it is illuminated and shown every Monday afternoon during the season. One of the members conducts the party through the upper and lower prisons, and explains everything of interest connected with them. Dr. Parker, whose labours have done so much to elucidate this part of ancient Rome, was the guide on the occasion of my visit; and as the party was unusually small, we had a better opportunity of seeing what was to be seen, and hearing the guide's observations.
