Rome listened open-mouthed. The change from Domitian's formula, "Your god and master orders it," was too abrupt to be immediately understood. Before it was grasped Trajan was off again; this time to the Danube and beyond it, to Dacia and her fens.
Many years later—a century or two, to be exact—a Persian satrap loitered in a forum of Rome. "It is here," he declared, "I am tempted to forget that man is mortal."
He had passed beneath a triumphal arch; before him was a glittering square, grandiose, yet severe; a stretch of temples and basilicas, in which masterpieces felt at home—the Forum of Trajan, the compliment of a nation to a prince. Dominating it was a column, in whose thick spirals you read to-day the one reliable chronicle of the Dacian campaign. Was not Gautier well advised when he said only art endures?
There were other chronicles in plenty; there were the histories of AElius Maurus, of Marius Maximus, and that of Spartian, but they are lost. There is a page or two in the abbreviation which Xiphilin made of Dion; Aurelius Victor has a little to add, so also has Eutropus, but, practically speaking, there is, apart from that column, nothing save conjecture.
Campaigns are wearisome reading, but not the one that is pictured there. You ask a curve a question, and in the next you find the reply. There is a point, however, on which it is dumb—the origin of the war. But if you wish to know the result, not the momentary and transient result, but the sequel which futurity held, look at the ruins at that column's base.
The origin of the war was Domitian's diplomacy. The chieftain whom he had made king, and who had been surprised enough at receiving a diadem instead of the point of a sword, fancied, and not unreasonably, that the annuity which Rome paid him was to continue forever. But Domitian, though a god, was not otherwise immortal. When he died abruptly the annuity ceased. The Dacian king sent word that he was surprised at the delay, but he must have been far more so at the promptness with which he got Trajan's reply. It was a blare of bugles, which he thought forever dumb; a flight of eagles, which he thought were winged.
In the spirals of the column you see the advancing army, the retreating foe; then the Dacian dragon saluting the standards of Rome; peace declared, and an army, whose very repose is menacing, standing there to see that peace is kept. And was it? In the ascending spiral is the new revolt, the attempt to assassinate Trajan, the capture of the conspirators, the advance of the legions, the retreat of the Dacians, burning their cities as they go, carrying their wounded and their women with them, and at last pressing about a huge cauldron that is filled with poison, fighting among themselves for a cup of the brew, and rolling on the ground in the convulsions of death. Farther on is the treasure of the king. To hide it he had turned a river from its source, sunk the gold in a vault beneath, and killed the workmen that had labored there. Beyond is the capture of the capital, the suicide of the chief, a troop of soldiers driving captives and cattle before them, the death of a nation and the end of war.
The subsequent triumph does not appear on the column. It is said that ten thousand beasts were slaughtered in the arenas, slaughtering, as they fell, a thousand of their slaughterers. But the spectacle, however fair, was not of a nature to detain Trajan long in Rome. The air there had not improved in the least, and presently he was off again, this time on the banks of the Euphrates, arguing with the Parthians, avoiding danger in the only way he knew, by facing it.
It was then that the sheen of the purple glowed. If lustreless at home, it was royally red abroad. In a campaign that was little more than a triumphant promenade he doubled the empire. To the world of Caesar he added that of Alexander. Allies he turned into subjects, vassals into slaves. Armenia, Mesopotamia, Assyria, were added to the realm. Trajan's footstools were diadems. He had moved back one frontier, he moved another. From Britain to the Indus, Rome was mistress of the earth. Had Trajan been younger, China, whose very name was unknown, would have yielded to him her corruption, her printing press, her powder and her tea.
That he would have enjoyed these things is not at all conjectural. He was then an old man, but he was not a good one—at least not in the sense we use the term to-day. He had habits which are regarded now less as vices than perversions, but which at that time were taken as a matter of course and accepted by everyone, even by the stoics, very calmly, with a grain of Attic salt at that. Men were regarded as virtuous when they were brave, when they were honest; the idea of using the expression in its later sense occurred, if at all, in jest merely, as a synonym for the eunuch. It was the matron and the vestal who were supposed to be straight, and their straightness was wholly supposititious. The ceremonies connected with the phallus, and those observed in the worship of the Bona Dea, were of a nature that no virtue could withstand. Every altar, Juvenal said, had its Clodius, and even in Clodius' absence there were always those breaths of Sapphic song that blew through Mitylene.
