CHAPTER III.
THE COLISEUM AND ESQUILINE.
Meta Sudans.
On the road from the Forum Romanum to the Coliseum, after passing through the Arch of Titus, we descend between the platform and ruins of the Temple of Venus and Rome, and the remains called the lavacrum of Heliogabalus, mentioned previously, and, close to the south-western corner of the mass of substruction on the left, we find a conical column of brickwork about thirty feet high. A large breach on the side towards the Coliseum shows that the centre was pierced with a perpendicular pipe, and the eastern exhibits traces of having been divided into three ledges or stages. This conical building stood in the centre of a circular basin, the ruin of which has been traced out and restored. The shape would of itself point to the purpose which this building served, even if this were not rendered clear by the remains of a watercourse which descended to it from the Esquiline. The name Meta Sudans by which the ruin is known comes from the mediæval list of buildings known as the Curiosum Urbis, but the earliest authentic authority to which we can appeal for its date is a coin of Alexander Severus, A.D. 222. The passage of Seneca in which he gives the name Meta Sudans as being a spot at which the flute-players and trumpeters made a din by their practice, does not give us any information as to its position, and therefore we are not justified in assuming that the fountain was erected in Nero’s time.[67] The coins of Titus which represent the Coliseum do not show it. Cassiodorus and other chronologists place the date of the Meta Sudans in Domitian’s reign, and this agrees with the coins of Titus and also with the nature of the brickwork, which is of the Flavian era.
Arch of Constantine.
Near the Meta Sudans at the entrance of the Via di S. Gregorio stands the Arch of Constantine, which is the most completely preserved of all ancient Roman buildings. The name of Constantine, revered by subsequent ages, seems to have defended the archway from the barbarous spoliation which attacked most of the great monuments of Rome. The most interesting feature of this arch in the history of art is the proof which it gives of the decline of art in the fourth century. Some of the reliefs with which it is ornamented were taken from an older arch, probably that which formed the entrance to Trajan’s Forum, and those which are of Constantine’s time show a coarse and harsh style of execution in lamentable contrast to the flowing and delicate lines of the more ancient work by their side.
Among the sculptures which belong to the earlier and better period are the large reliefs under the central arch and those which are placed on either end of the attica. These four were originally parts of a larger relief which has been sawn into four equal pieces for the purpose of adorning Constantine’s arch. The order in which they stood in the original design has been pointed out by Bellori. The first part is that now placed on the inside of the middle archway towards the Coliseum, the second stands on the side of the attica over the arch towards the Cælian, the third on the inside of the middle archway towards the Palatine, and the fourth upon the attica on the same side. When united they represented Trajan crowned by Victory, with the goddess Roma standing near, a battle between Dacians and Romans, ending in the defeat and submission of the barbarian army. The dress of the Roman soldiers and of the Dacians is similar to that represented on Trajan’s column, and quite different from the Roman military habit in the age of Constantine. Beside these four rectangular reliefs the eight circular sculptures which stand over the smaller archways belong to the time of Trajan. They represent hunting scenes and sacrificial ceremonies. One of them, the second from the left, upon the side towards the Coliseum, has a remarkable figure of the Emperor with a nimbus or cloud encircling his head, exactly similar to those represented round the heads of modern saints. The eight large reliefs upon the attica over the side archways are also of the workmanship of Trajan’s time, and commemorate some of the exploits of that emperor, among which may be mentioned the construction of a road through the Pontine marshes represented upon the second relief from the left on the side of the attica towards the Coliseum. The reclining figure with a wheel represents the road, and the other figures the surveyors, one of which is perhaps Apollodorus, the famous Greek architect of Damascus. The other reliefs upon the sides of the attica represent interviews of Trajan with barbarian princes, and the common sacrifice of the Suovetaurilia, so frequently depicted on the reliefs of the columns of that emperor, and also on the large marble screens now standing in the Forum Romanum. The remainder of the sculptures belong to the Constantinian era, and contain, viewed as works of art, nothing worth attention. One of them on the side next to the Coliseum is, however, of great interest to the antiquarian, as it represents the rostra of the later Empire and the northern end of the Forum, with the arches of Severus and Tiberius, and the end of the Basilica Julia, and another, on the side towards the Via di S. Gregorio representing the victory of Constantino over Maxentius at the Milvian bridge, is historically valuable.
The figures which stand in front of the attica have the Dacian costume, and have been removed from some one of Trajan’s buildings. Upon the side of the central archway can be still seen the traces of nails which fastened some Roman ensigns to the stones. Similar traces of nails are to be seen upon the arch of Severus as before mentioned.
