The character and statesmanship of Tiberius is one of the most vexed problems in Roman history; and it is significant to observe how, in all the discussions about it, the question perpetually reverts to another-- the view to be taken of the personality of the historian who wrote nearly a century after Tiberius' accession, and was not born till long after his death. In no part of his work does Tacitus use his great weapon, insinuation of motive, with such terrible effect. All the speeches or letters of the Emperor quoted by him, almost all the actions he records, are given with this malign sidelight upon them: that, in spite of it, we lose our respect for neither Emperor nor historian is strong evidence both of the genius of the latter and the real greatness of the former. The case of Germanicus Caesar is a cardinal instance. In the whole account of the relations of Tiberius to his nephew there is nothing in the mere facts as stated inconsistent with confidence and even with cordiality. Tiberius pronounces a long and stately eulogy on Germanicus in the senate for his suppression of the revolt of the German legions. He recalls him from the German frontier, where the Roman supremacy was now thoroughly re-established, and where the hot-headed young general was on the point of entangling himself in fresh and dangerous conquests, in order to place him in supreme command in the Eastern provinces; but first he allows him the splendid pageant of a Roman triumph, and gives an immense donative to the population of the capital in his nephew's name. Germanicus is sent to the East with _maius imperium_ over the whole of the transmarine provinces, a position more splendid than any that Tiberius himself had held during the lifetime of Augustus, and one that almost raised him to the rank of a colleague in the Empire. Then Germanicus embroils himself hopelessly with his principal subordinate, the imperial legate of Syria, and his illness and death at Antioch put an end to a situation which is rapidly becoming impossible. His remains are solemnly brought back to Rome, and honoured with a magnificent funeral; the proclamation of Tiberius fixing the termination of the public mourning is in its gravity and good sense one of the most striking documents in Roman history. But in Tacitus every word and action of Tiberius has its malignant interpretation or comment. He recalls Germanicus from the Rhine out of mingled jealousy and fear; he makes him viceroy of the East in order to carry out a diabolically elaborate scheme for bringing about his destruction. The vague rumours of poison or magic that ran during his last illness among the excitable and grossly superstitious populace of Antioch are gravely recorded as ground for the worst suspicions. That dreadful woman, the elder Agrippina, had, even in her husband's lifetime, made herself intolerable by her pride and jealousy after her husband's death she seems to have become quite insane,
