Whether this "Gallic theory," as it is called, concerning the Apollo, Diana, and Athena be correct or no, it is the most satisfactory in sentiment of any that has been advanced, and certainly, when we consider the three statues in this connection, there is nothing inharmonious in the supposition that they made the important parts of a whole which may have had many other figures of lesser importance in it.

There are many other statues of the Roman period in various museums, but I shall leave this part of our subject here, and speak briefly of the historical sculpture in the reliefs upon the triumphal arches of the Eternal City. In an age when martial glory was the chief desire of man, and among a people who accorded to successful generals the highest honors, it was most natural that the conquerors should desire to place some monument of their exploits where it would be constantly before the eyes of the people, and thus keep in perpetual remembrance their valiant deeds and their great successes.

We read that pictures of the foreign scenes of sieges and battles were displayed in public places in Rome at a very early date. We cannot find records of plastic works of this sort before the time of the emperors, but after such sculptures came into favor they were multiplied rapidly. The principal historical reliefs in Rome were upon the arches of Claudius, Titus, Trajan, Marcus Aurelius, and Septimius Severus, and on the architrave of the temple of Minerva in the Forum.

Of the arch of Claudius there are some remaining fragments of sculpture, now in the Villa Borghese. The arch of Titus was erected to celebrate the taking of Jerusalem in A.D. 70. It was restored in 1822. The frieze represents both a triumphal procession and one of sacrifice. The picture we give here shows a company of warriors in the dress of peace, who bear articles of booty taken from the conquered city. They have the candelabra with seven branches, the table of the shew-bread, the silver trumpets, etc. This will give you a good idea of these reliefs. (Fig. 66.)

The arch of Trajan no longer stands, and its reliefs are now on the arch of Constantine; but Trajan's Pillar is one of the best preserved of all the antique monuments of Rome, and with some account of this column and a picture from it we will leave the historical sculptures of Rome. The Senate and people of Rome decreed that this column should be erected to the memory of Trajan, and it was in the centre of the Forum which bore the same name—the Forum Trajani. The column is about one hundred and six feet high, and originally was surmounted by a bronze statue of Trajan, which was replaced by one of St. Peter by Pope Sixtus V. A band of reliefs runs around this pillar in a spiral form; this band is six hundred feet long, and the sculptures represent Trajan's campaign against the Dacians. Many of the figures lose their effect on account of the height at which they are placed. There are more than a hundred scenes upon it, in which are about twenty-five hundred human figures, besides many horses and other objects. The whole is executed with the greatest care.

The real object of the whole work was to glorify the Emperor Trajan, and he is represented in many of the scenes; sometimes he is conducting engagements, storming a fort, or encouraging his troops; again he is holding an audience, protecting the women of a conquered city, or sitting in judgment on captives. Fig. 67 represents the Dacians assaulting a Roman fort. It is winter, and while some have crossed the ice in safety, others have broken through. Everything about it is represented in the most life-like and matter-of-fact manner, and this shows distinctly the principal difference between the Greek and the Roman art when the latter was not influenced by the former. It is pure, realistic, historical sculpture, and this pillar shows this at its very best estate; it is a splendid specimen of this kind of art. In all these many scenes there are but two mythological figures: one is Selene, used to represent Night, and the other is Jupiter tonans, who indicates Storm. But the correctness and elegance of the sculptures show what the Greek teaching did for the Romans; for it was to the Greeks that the latter owed their knowledge of the human form and their power to render it properly in sculpture.
