Dion Cassius tells the story of Trajan’s accession as follows:
“Nerva, seeing that he was despised on account of his advanced age, ascended to the Capitol and said in a loud voice: ‘May the thing be fortunate and well-pleasing to the senate, and the Roman people as well as to myself! I adopt M. Ulpius Trajan.’ After which he declared him Cæsar in the senate and wrote to him with his own hand (Trajan was commanding in Germany):
“‘May the Danubians expiate my tears under the stroke of thy darts.’
“Thus Trajan became Cæsar, and afterwards emperor, though Nerva had relatives. But Nerva did not place his kindred before the good of the state; although Trajan was a Spaniard and not an Italian or even the son of an Italian, he was nevertheless adopted in spite of this, for to that day no foreigner had been emperor of the Romans; Nerva thought that it was a man’s merit, and not his country which was the important question. He died after this adoption, having reigned one year, four months, and nine days; he had lived sixty-five years, ten months, and ten days.
“Trajan before attaining to the empire had had the following dream: It seemed to him that an old man clothed in the pretexta and adorned with a crown, in the fashion in which the senate is represented, marked his seal on him with a ring on the left side of the neck and then on the right. When he had become emperor he wrote to the senate with his own hand, saying amongst other things that he would not put to death nor brand as infamous any worthy man; and these promises he confirmed with an oath both at the time and subsequently. Having sent for Ælianus and the prætorian guards who had risen against Nerva, as if with the intention of making use of them, he rid himself of them. He had no sooner reached Rome than he made several regulations for the reformation of the state and in favour of worthy men, whom he treated with so much consideration that he granted funds to the cities of Italy for the education of the children whose benefactor he became. The first time that his wife Plotina entered the palace, having reached the top of the steps and turning towards the temple, she said, ‘Such as I enter, so I would depart.’ Throughout his reign she conducted herself in such a manner that no reproach could be made against her.”[g]
Trajan (M. Ulpius Trajanus Crinitus), 98-117 A.D.
[98-101 A.D.]
By birth, as just noted, Trajan was a Spaniard, although his father had filled the office of consul in Rome. Not more than fifty years earlier it would have been intolerable to the Romans to obey a foreigner; but in Trajan’s time a man’s birthplace was no longer taken into consideration. So greatly had opinions and circumstances altered in consequence of the growing amalgamation of the empire into a single state.
Nerva died in the year after the appointment of his co-regent (Jan., 98). The latter, who at the time of his accession was in the prime of life, and reigned from 98-117, possessed all the qualities which the spirit of the times, the existing state of things, and the welfare of the empire required of a ruler. As a ruler he only committed a single error, he tried to extend the borders of the empire by conquest, and thus led the Romans once more along a path which they had abandoned since the time of Augustus, to the great benefit of the state. Trajan combined a lofty spirit with all the best qualities of a soldier. He had received a military training, and had spent the greater part of his previous life in camp; he was therefore lacking in conventional culture, the hardships of military service had given him health and strength, while a simple and hardy life had preserved the firmness and uprightness of his mind. By his unvarying regard for law and justice, for equality and civil virtue, for ancient custom, and for the reputation of the highest office in the state, no less than by his choice of subordinates and friends (amongst whom were two of the best writers of those days, Pliny the Younger and Tacitus) Trajan showed how little culture and learning was necessary, where such qualities existed, to enable a man worthily to take his place at the head of the empire.
