As we have already stated, the story of Trajan's expeditions into Dacia is recorded in the bas-reliefs of the column bearing his name and still existing in Rome. These bas-reliefs have been subject to various readings and interpretations, but we have so far avoided referring to them under the impression that they can only be taken in a general sense to represent the exploits of Trajan, and that any attempt to extract from them the names of localities is at best a hazardous experiment. With these reservations, however, it is safe to say that they vividly represent incidents of the campaign and bring us face to face with the warlike character and customs of the contending nations. The progress of the expedition, as shown on the column, is divided into sections, placed one above another, and separated by stems of trees which coil round the column; in the first of these sections we see the passage of the army across the Danube over two bridges of boats. The Roman soldiers are chiefly bareheaded, carrying their shields and helmets, and many bearing standards with eagles, images of the gods, and other devices. Some of the objects carried are supposed to be lanterns, from which it is inferred that the passage took place at night. In advance are the trumpeters bearing long curved horns, and the led horses of Trajan and his generals. The last-named have already crossed the river, and Trajan is seated on a platform surrounded by his officers, haranguing his men. Next we find ourselves in the enemy's country, although there are no signs as yet of the Dacians, and the two succeeding sections of the column are occupied by the progress of the Roman arms. The soldiers are felling timber, removing obstructions, and building forts and bridges, over all of which operations Trajan is seen to preside in person. In the fourth division the Dacians appear, suing for peace; the emissaries are clad in long robes, and Trajan meets them outside a fort. Then follow further incidents in the campaign; encounters take place between the opposing forces, in which the Dacians are defeated and their dead lie scattered on the ground. They are then seen retreating with their women and children, devastating the country and slaying their cattle which are heaped up in piles. Trajan is again present, sparing the old men, women, and children, and making prisoners. Now the Dacians are the attacking party, and the Romans defend themselves behind forts; and then again the army is in motion with Trajan at its head, crossing rivers, and erecting fortifications. In the next section the Dacians have made a stand, and the scene represents a pitched battle in which they are again defeated with great slaughter. All the incidents of the fight are vividly depicted: Romans fighting from their chariots, Dacians and their allies mounted and on foot, prisoners brought in, and a man, apparently a spy, bound before Trajan himself. Then follows a further advance, which occupies some of the succeeding scenes of the panorama. Here the Romans fall into an ambuscade, from which they extricate themselves; there they pass a post of danger, apparently a wooden stronghold of the Dacians, under cover of a wall of shields held aloft by the soldiers; and at length they arrive before a fortified town, where Trajan is again seen seated upon a platform, surrounded by his generals, whilst the Dacians, one of whom is supposed to be Decebalus himself, kneel round about, suing for peace. In this scene the attire, emblems, and accoutrements of the two contending nations are presented in marked contrast. The Roman standards and eagles have already been mentioned; those of the Dacians generally represent serpentine monsters at the end of a long pole.[93] Whilst the Romans carry their tall, curved, oblong shield, the oval ones of the Dacians ornamented with floral devices lie heaped in confusion. Most of the Dacians are bareheaded, but some, supposed to be chiefs, wear a head-dress resembling a cap of liberty. Another section completes the panorama of the first expedition, representing the embarkation and landing of Trajan; the sacrifices, triumph, and rejoicings in the capital.
But Decebalus had no more intention of abiding by the terms of his treaty with the Roman emperor than had Trajan with that of his predecessor. The Dacian king had no sooner seen his enemy's back than he repaired his fortresses, armed his people afresh, sought new alliances with his neighbours, and commenced depredations upon the territories of Rome and her allies. Then it was that Trajan prepared to chastise the barbarians, and this time he determined to crush the Dacian power completely, and to annex the conquered country as a Roman province. Although he is said to have been in Mœsia in a.d. 104, the actual movements against Dacia only commenced the following year, and in this as in the preceding expedition the routes pursued by the Roman army have not been clearly defined. The bridge across the Danube from Gladowa to Turnu-Severin was most likely completed, and part, if not the whole, of Trajan's army crossed there. Those writers who believe that in the first expedition a portion of the forces entered from Pannonia, say that, knowing the geography of the country better, Trajan now sent a division up the valley of the Theiss, crossing the Danube at Viminacium; whilst there is little doubt that a portion of the army continued the march eastward along the Mœsian bank of the Danube, crossed at a station opposite the mouth of the Alutus (now Oltu), landed near the modern Celeiu, and, crossing the plain, entered the mountain fastnesses through the Rothenthurm pass.[94]
By whatever routes Trajan's army invaded the dominions of the doomed king, it is known that his advance was prompt and successful, and that this time the fame of the Roman arms prevented Decebalus from securing many allies. He once more sued for peace; but Trajan's terms being a virtual relinquishment of his independence, he prepared himself for a supreme and desperate effort for the defence of his kingdom. At first it is said that he attempted to remove Trajan by assassination, but that his emissaries were detected and put to death. Another expedient seems to have been temporarily successful. He managed to decoy into his power Longinus, a Roman general, said to have been a great favourite of Trajan, and, holding him as a hostage, Decebalus demanded extravagant terms of peace. To this proposal Trajan gave an evasive reply, in order, if possible, to save the life of his officer. The last-named, however, with true Roman patriotism, had a message conveyed to Trajan by his freedman, advising him to proceed with his operations, and at the same time he himself took a dose of poison in order to relieve his master from further perplexity on his account. Decebalus then offered to give up the body of the Roman general and certain other captives in return for the escaped freedman, but Trajan returned no answer to his proposal. Very little is known of the incidents of this campaign, excepting that Trajan forced the passes of the Carpathians, and, taking one defended post after another, drove the enemy into the vicinity of his capital; that the tribes who had allied themselves with the Dacians, amongst whom the Sarmatians, Jasyges, and Burri are named, deserted them one by one, and that the Romans at length laid siege to Sarmizegethusa, where Decebalus had taken refuge. After a brave but ineffectual defence the king, rather than yield himself a prisoner, committed suicide with his sword; whilst his followers, after setting fire to the town, imitated the example of their leader by taking poison. The head of Decebalus was cut off and sent to Rome by Trajan, who discovered and divided amongst his soldiers vast spoils and treasures which the Dacians had endeavoured to conceal, and then returned to Rome, where (a.d. 106) a triumph was celebrated on even a grander scale than after the conclusion of his first expedition.[95]
Before drawing to a close this hasty survey of the rise and fall of the Dacian monarchy, let us turn again for a moment to the bas-reliefs upon Trajan's Column, the indelible and, after all, the most trustworthy record of his second expedition.[96] Passing hastily over the first scenes, which comprise tho landing of his troops, the assault and capture of a fortified place, the defeat of the Dacians, and what appears to be a refusal on the part of Trajan to grant them peace, we have a very faithful and circumstantial picture of a halt, where the emperor is present at the offering of a bull as sacrifice. Then there is a continuance of the march inland, followed by fierce contests between the two armies. At length the Romans arrive before a walled city (probably Sarmizegethusa) where all the incidents of a siege, including personal adventures, are portrayed. A Roman soldier, standing at the top of a scaling ladder, has struck off the head of one of the Dacians on the wall, whilst the latter are seen hurling stones and other missiles at those engaged in the assault. Then comes another application for peace, a Dacian prince kneeling at the feet of Trajan; whilst in the same section, separated only by a couple of thin trees, we have the scene of the Dacians setting fire to their city, and in close contiguity is their dying leader. The remaining scenes depict the Roman soldiers dividing the spoil. Trajan is addressing them, distributing rewards, and bidding them adieu. Then follow secondary incidents; the building of fortresses by the Romans; one or two more contests in which Trajan's generals defeat the Dacians, driving them into the mountains, whither they are seen fleeing with their flocks, women, and children. One of the last scenes represents the second triumph of Trajan, with soldiers who arrive bearing the head of Decebalus. Some of the minor incidents in the panorama are intended to exhibit the barbarity of the Dacians, one being the exhibition of a row of heads stuck upon spears on the walls of a town or fortress; another the burning and torturing of naked Roman prisoners by Dacian women. Altogether these bas-reliefs, which are said to be the work of several artists, present anything but an edifying spectacle of the ancient mode of warfare.
III.
Whatever uncertainty attaches to the details of Trajan's expeditions, there is none as to their ultimate result, nor concerning the chief operations of the conqueror and his successors in the newly-acquired territory, which was formally annexed as a province of the Empire. Some historians have attempted to define with great minuteness the boundaries of the new province, but more cautious writers content themselves with naming approximate limits; and these have done wisely, as there is no doubt that the movements of the neighbouring tribes and even of the conquered Dacians (for it is a mistake to suppose, as some do, that they went out of existence) prevented any strict line of demarcation. The nominal boundaries of Roman Dacia were the river Theiss on the west, the Pruth on the east, 'barbarians' on the north, and the river Danube on the south. The country actually colonised embraced the Banate of Temesvar, Transylvania (Siebenbürgen), and Roumania as they exist to-day. There were several centres of colonisation, of which the chief was Ulpia Trajana, including the old capital of Decebalus, Sarmizegethusa (now Varhely), and other important centres were Apulum and Cerna or Tierna.[97]
Trajan and his successors built fortifications, walls, and towns; and, attracted partly by the fertility of the plains and partly by the gold mines of the Carpathians, the Roman colonies soon swelled in numbers and importance.[98] Different opinions have been expressed concerning the character of these colonists. One modern writer, Carra, who is considered an authority in Roumanian history, says that the Romans regarded Dacia as the French, Cayenne, and sent thither a colony consisting of the scum of the principal towns of Greece and the Roman Empire. Their descendants, he adds, who inherited their vices and cowardice, were turn by turn conquered and enslaved by the Sarmatians, Huns, and Tartars.[99] This is a statement which rather affects the feelings of modern Roumanians than the current of historical events, and it brings us face to face with an enquiry which we shall have to handle with great circumspection, namely, the descent of the modern Roumanians from the old Daco-Roman colonists, lest we find ourselves involved in a controversy that would fill volumes. So far as the records of Roman history enable us to judge, Carra has done great injustice to the colonists of Dacia. It is true that the Romans banished some of their malefactors, and especially political offenders, to their colonies, as Ovid was expatriated; and that Trajan colonised Dacia from various parts of the Empire; but the custom of the Roman generals, which Trajan would doubtless have followed, was to divide the most fertile districts amongst their veteran soldiers,[100] and therefore, if the charges of cowardice and debauchery made by Carra were true, they would apply to the bravest in the legions who had conquered the almost indomitable Decebalus. But Carra lived and wrote at a time (a.d. 1777) when cool judgment could hardly be expected in a writer on Roumania, and if he were alive to-day he would be surprised to hear that there is a school of modern historians who, using his very authorities, deny that the descendants of the Daco-Roman colonists were ever to be found on Dacian ground during the incursions of the eastern barbarians. But of that more hereafter.[101]
The history of the Roman occupation of Dacia, which lasted from the time of Trajan until it was evacuated by Aurelian,[102] affords little to interest the reader. Dacia was, so to speak, the outwork of the Empire which served to hold the barbarians at bay during its 'decline and fall;' and the country was more prosperous than during the period of its independence, when the tribes were constantly at war with one another and there was no settled government. That the attitude of the barbarians was threatening even a few years after the death of Trajan is, however, more than probable, for his immediate successor, Hadrian, contemplated withdrawing his legions, and destroyed the bridge across the Danube, 118 or 120 a.d. Some writers, indeed, attribute this act to his jealousy of Trajan, others to his hatred of Apollodorus, the architect; but most probably the cause assigned by Dion Cassius, that it was to prevent its being used by the barbarians for making inroads into Mœsia, was the true one.[103] During the reigns of Antoninus Pius and Marcus Aurelius for about half a century, the barbarians were kept in check, although even during that period they had managed to encroach upon the Roman territory.
At the beginning of the third century, however, the Roman hold on Dacia began to be very precarious, and we approach the time when the dark veil of the so-called barbarian ages is drawn over the history of Europe. That the Roman emperors had to contend, with very varying fortunes, with barbarous tribes is certain, and that their arms were still frequently successful is proved by the erection of fortresses and towns, named after their emperors, on the borders of their possessions. For example, Caracalla defeated certain barbarous hordes about a.d. 212, and assumed the name of 'Geticus,' but whether the conquered tribes were Dacians or Goths is uncertain.
