In 113 or 114 Trajan left Italy to make war in the East. The never-ending Parthian problem confronted him, and with it were more or less connected a number of minor difficulties. Already by 106 the position of Rome in the East had been materially improved by the peaceful annexation of districts bordering on the province of Syria. The district of Damascus, hitherto a dependency, and the last remaining fragment of the Jewish kingdom, were incorporated with Syria; Bostra and Petra were permanently occupied, and a great portion of the Nabathæan kingdom was constituted the Roman province of Arabia. Rome thus obtained mastery of the most important positions lying on the great trade-routes from East to West. These changes could not but affect the relations of the Roman with the Parthian empire, and the affairs of Armenia became, in 114, the occasion of war. Trajan's campaigns in the East ended in complete though brilliant failure. In the retreat from Ctesiphon (117), the old emperor tasted for almost the first time the bitterness of defeat in the field. He attacked the desert city of Hatra, westward of the Tigris, whose importance is still attested by grand ruins. The want of water made it impossible to maintain a large force near the city, and the brave Arabs routed the Roman cavalry. Trajan, who narrowly escaped being killed, was forced to withdraw.
A more alarming difficulty lay before him. Taking advantage of the absence of the emperor in the far East, and possibly by an understanding with the leaders of the rising in Armenia and the annexed portions of Parthia, the Jews all over the East had taken up arms at the same moment, and at a given signal. The massacres they committed were portentous. In Cyprus 240,000 men are said to have been put to death, and at Cyrene 220,000. At Alexandria, on the other hand, many Jews were killed. The Romans punished massacre by massacre, and the complete suppression of the insurrection was long delayed, but the Jews made no great stand against disciplined troops. Trajan still thought of returning to Mesopotamia, and of avenging his defeat at Hatra, but he was stricken with sickness and compelled to take ship for Italy. His illness increasing, he landed in Cilicia, and died at Selinus in that country about the end of July, 117.
Trajan, who had no children, had continually delayed to settle the succession to the throne, though Pliny, in the "Panegyric" had pointedly drawn his attention to the matter, and it must have caused the Senate much anxiety. Whether Hadrian, the cousin of Trajan, was actually adopted by him or not, is impossible to determine; certainly Hadrian had not been advanced to any great honors by Trajan. Even his military service had not been distinguished. Plotina asserted the adoption, and it was readily and most fortunately accepted, if not believed, as a fact.
The Senate had decreed to Trajan as many triumphs as he chose to celebrate. For the first time a dead general triumphed. When Trajan was deified, he appropriately retained, alone among the emperors, a title he had won for himself in the field, that of "Parthicus." He was a patient organizer of victory rather than a strategic genius. He laboriously perfected the military machine, which when once set in motion went on to victory. Much of the work he did was great and enduring, but the last year of his life forbade the Romans to attribute to him that felicitas which they regarded as an inborn quality of the highest generals. Each succeeding emperor was saluted with the wish that he might be "better than Trajan and more fortunate than Augustus." Yet the breach made in Trajan's felicitas by the failure in the East was no greater than that made in the felicitas of Augustus by his retirement from the right bank of the Rhine.[Back to Contents]
DIOCLETIAN
(245-313)
Caius Valerius Diocletianus, one of the most famous of the Roman emperors, was, as De Quincey says, "doubtless that man of iron whom the times demanded." He was born at Dioclea, in Dalmatia, some say at Salona, about A.D. 245 according to some, but others make him ten years older. His original name was Diocles, which he afterward changed into Diocletianus. He is said by some to have been the son of a notary, by others the freedman of a senator named Anulinus. He entered the army at an early age, and rose gradually to rank; he served in Gaul, in Mœsia, under Probus, and was present at the campaign against the Persians, in which Carus, then emperor, perished in a mysterious manner. Diocletian commanded the household or imperial body-guards when young Numerianus, the son of Carus, was secretly put to death by Aper his father-in-law, while travelling in a close litter on account of illness, on the return of the army from Persia. The death of Numerianus being discovered after several days by the soldiers near Calchedon, they arrested Aper and proclaimed Diocletian emperor, who addressing the soldiers from his tribunal in the camp, protested his innocence of the death of Numerianus, and then upbraiding Aper for the crime, plunged his sword into the traitor's body.
The new emperor observed to a friend that "he had now killed the boar," punning on the word Aper, which means a boar, and alluding to the prediction of a soothsayer in Gaul, who had told him that he would become emperor after having killed a boar (Vopiscus, in "Hist. Aug."). Diocletian, self-composed and strong-minded in other respects, was all his life an anxious believer in divination, which superstition led him probably to inflict summary punishment upon Aper with his own hands. He made his solemn entrance into Nicomedia in September, 284, which town he afterward chose for his favorite residence.
Carinus, the other son of Carus, who had remained in Italy, having collected a force to attack Diocletian, the two armies met at Margum, in Mœsia, where the soldiers of Carinus had the advantage at first, but Carinus himself being killed during the battle by his officers, who detested him for his cruelty and debauchery, both armies joined in acknowledging Diocletian emperor in 285. Diocletian was generous after his victory, and, contrary to the common practice, there were no executions, proscriptions, or confiscations of property; he even retained most of the officers of Carinus in their places.
