[17-20 A.D.]
In the East, Germanicus had equal successes. Everywhere he had given justice and peace as the watchword of the new government. In Armenia, he gave the crown to Zenon, son of the king of Pontus and a faithful vassal of the empire. This prince had long since adopted Armenian customs. Germanicus had made a wise choice and the whole nation applauded. Cappadocia, whose old king had just died in Rome, was, like Commagene, reduced to a province. In Syria, Germanicus concluded an alliance with Artabanus, who only asked for the removal of his rival. In Thrace, one of the two kings had killed the other. The assassin was sent to Alexandria and, later on, put to death.
A more serious affair had begun the preceding year [17 A.D.] in Africa. A Numidian, Tacfarinas, a deserter from the legions, had collected and disciplined some troops and persuaded the Musulanii and Moors to rise. The proconsul defeated him, and for this vigorous act, which gave security to a fertile country, he received the distinction of a triumph.
DEATH OF GERMANICUS (19 A.D.); EXTERNAL AFFAIRS
At this prosperous moment Germanicus died, poisoned, it has been alleged, by order of Tiberius. Yet could a man such as he, thoughtful, serious, calculating, have committed such a senseless crime? The death of his adopted son took away no rival. He knew him to be incapable of treason and his death deprived him of a necessary support. The mystery is still unsolved. The perpetrator of the crime was, it is said, Piso, a patrician of a violent disposition, who had obtained the governorship of Syria during the time that Germanicus was in the East. It was on his return from a journey in Egypt, undertaken without permission and in defiance of Tiberius, that Germanicus found that the arrangements he had adopted had been interfered with by Piso.
Lively quarrels took place between them, and the insubordinate governor, rather than yield, preferred to quit the province. The news that Germanicus was seriously ill stopped him at Antioch. The prince becoming better, Piso opposed the celebration of any fêtes in honour of the event, and went on to Seleucia, where the report of an alarming relapse made him stop again. Amongst Agrippina’s attendants there was mention of poisoning, and emissaries from Piso who had come to report on the progress of the malady, could show, it was said, by whose hand the blow had been struck. Germanicus died. His body was burnt in the Forum at Antioch, and Agrippina, having piously gathered the ashes, landed at Brundusium, carrying the burial urn herself, and followed by an immense crowd, all plunged in heart-breaking sorrow.
Piso received the news of Germanicus’ death with unseemly joy, and immediately set off to return to his province. The legate and the senators throughout Syria had conferred the governorship on one of themselves. Piso did not recoil before the prospect of civil war. Tiberius would not pardon him. Forced to embark, he returned to Italy, where accusers awaited him. These wanted the emperor alone to judge his cause. Now, had the emperor feared possible revelations he would have accepted, but he sent the accusers back to the senate. He presided at the trial, and the accused, says Tacitus, looked at him fearfully as he sat there pitiless, calm, impassive, and impenetrable. This portrait of Tiberius is the most faithful Tacitus has left.
Piso killed himself in his own house. The emperor rewarded the three friends of Germanicus who had come as accusers, and asked for Nero, the eldest of Germanicus’ sons, the honour of the quæstorship five years before the regulation age, and married him to a daughter of Drusus. Later on he begged the same favour for the second son of Germanicus.
