To what extent this animosity between the two ladies was carried it is difficult to determine. Some historians claim that it resulted in placing another awful crime to Livia's account. Germanicus died in Seleucia in the thirty-fourth year of his age, of some mysterious malady; and there were many who at once whispered that Livia had been the means of bringing about his death by poisoning. But there is no proof of this, and a careful study of the known facts causes it to seem improbable. There was no motive for such an act, beyond the fact that the husband of Agrippina was exceedingly popular with the army and the people; but this was offset by his undoubted and enthusiastic devotion to Tiberius. The facts, so far as they are now ascertainable, are these: Piso, who was Proconsul of Syria, was instigated by his wife Plancina to acts of disrespect and animosity against Germanicus and Agrippina. This woman, who was of an exceedingly masculine temperament,--as is shown among other things by her habit of taking part in the exercises of the cavalry,--was a great favorite with Livia and shared her closest confidence. Plancina is said to have kept about her a woman named Martina, who had an evil reputation as being expert in the use of poisonous drugs, but of whose existence nothing more is known than the little that is told in this connection, Germanicus, on his deathbed, declared that he was cut short in his career by the dark devices of a woman. The news of his decease did not affect Livia with the same degree of sorrow as it did the populace; which fact tended to strengthen suspicion in the minds of the latter. But all this proves nothing, even though Piso, despairing of acquittal, destroyed himself during his trial, after having written a letter protesting his innocence. Nor does the fact that Plancina was protected by Livia furnish any proof that the aged and much-maligned empress was guilty of instigating the crime, if crime it was.

Agrippina, after the body of her husband had been burned on the funeral pyre, set forth in the depth of winter on her journey to Rome with his ashes. At every port where the fleet touched she received a sad but an imposing ovation. All the friends of her husband crowded to Brundusium, where she was to disembark; but they could not agree as to whether she should be received in respectful silence or with some more demonstrative expression of their sympathy. Tacitus thus depicts the affecting scene: "Nothing was settled when the fleet came sweeping slowly in, not rigged out in sprightly fashion, but wearing the ensigns of sadness. When, however, the widow descended from the ship, bearing the funeral urn in her hand, accompanied by her two infants and with her eyes steadily fixed on the ground, one simultaneous groan burst from the entire assemblage." Neither Tiberius, nor Livia, nor Antonia, the mother of Germanicus, attended the funeral. Tacitus gives the reasons that were alleged, but does not decide which was nearest the truth. "Tiberius and Livia either thought public lamentation beneath their dignity, or else they feared lest if folk peered into their faces their hypocrisy would be discovered. Whether sickness detained Antonia, or overmuch sorrow and inability to go through the ceremony, is not known. I would rather believe that she was held back by Tiberius and Livia, who did not leave the palace, that they might seem to mourn in private."

Agrippina had been exhorted by her dying husband, "as she would cherish his memory, and for the sake of their children, to divest herself of her unyielding spirit, and humble herself to Fortune in the storm of her displeasure; and, on her return to the city, not to irritate, in a competition for the mastery, those who were more than a match for her." Such advice given to a Roman matron would have appeared unnecessary to the men of the old regime; but there was now a throne in Rome, and consequently women jostled each other for the place of power behind it.

Agrippina needed just such counsel; but her nature would not allow her to profit by it. Irreproachable in her life, her virtues were not beautified by the divine gift of good humor; and she possessed no philosophy. Her mind was of that sort, more common among women than men, in which an idea having once been entertained is henceforth unassailable and undetachable by reason. Than this class of mind there is nothing more exasperating in human knowledge, and it is not to be wondered at that she irritated Tiberius. These two angered each other on every occasion of their meeting: the emperor by his cruel persecution of Agrippina's friends, and she him both by her air of martyrdom and by her evident and constant suspicion that he was planning some nefarious project against herself.

There lacked not ambitious men at the time who were ready to gather around the noble widow on the pretence of siding with her in her complaints against the emperor; they even sought to raise a party for the advantage of her children. She probably lent herself to some extent to these schemes, but not in sufficient degree to bring upon herself the violence of the suspicious and resentful Tiberius. Nevertheless, all her sons perished, except Caligula, whom a destiny unkind to the Roman people protected from the fate of his brothers.

Sejanus, the all-powerful favorite of the emperor, adroitly fanned the ever-smoldering animosity which naturally existed between Tiberius and Agrippina. He warned her to beware of poison, after having informed Tiberius that the matron suspected that the emperor had designs on her life. So, when the emperor politely handed her fruit, calling her attention to its excellence, she silently passed it to the slaves. "Can I avoid," he exclaimed to Livia, "treating this woman with harshness, when she accuses me to my face of seeking to poison her?"

The favorite Sejanus aimed at removing every heir to the imperial throne, in order that at the death of Tiberius he might rule in name, as he already did in effect. To achieve this end, he first seduced Livilla, the wife of the son of Drusus Tiberius; then he procured by her means the death of Drusus and asked Livilla in marriage. This the emperor refused. At length,--not, however, until after Agrippina's sons had been destroyed,--Antonia, the mother of Livilla, was constrained to write to Tiberius of the conspiracy of Sejanus, and by her means he was brought to justice. Livilla was starved to death by the command of her mother.

Livia seems to have been at all times an obedient and submissive wife. She was honored by the confidence of her husband. She shared in the knowledge of his deepest political projects, and her advice was asked in regard thereto. But there is no indication that she ever sought to dictate. It was otherwise, however, with Tiberius. Whether Livia considered that a mother's prerogative was more commanding than that of a wife, or that a larger share of the rule might be claimed by her on account of the fact that she had secured it for Tiberius, certain it is that the latter found there was not enough room for himself and the Augusta in the imperial palace. Suetonius informs us that on one occasion, when Tiberius had haughtily objected to his mother's sharing the government with him, Livia produced some letters which Augustus had written to her complaining of the pride and arrogance of Tiberius. The discovery that his mother had treasured these letters against him for so many years so wounded the emperor that he immediately left the city, and he never again saw his mother except for a few hours on one occasion.

It is said that during her last days, when there was little more to hope for and nothing else to do, Livia strove to defend Agrippina from the machinations of Sejanus and the hatred of Tiberius. For twenty years she had done somewhat to relieve the hardship of her daughter-in-law Julia's exile; but she never sought to have her recalled. Tacitus says that, having secretly overthrown her stepchildren in their prosperity, it was her custom to make an open show of compassion toward them in their adversity.

Livia the Augusta died in A.D. 29, at the age of eighty-five. The verdict of the historian is that she had been a stepmother to the commonwealth of Rome; and this perhaps expresses her politics better than any other term that could be employed. A faithful wife, a fond mother, she had relentlessly witnessed the removal of every obstacle in the way of Tiberius. For the sake of her son, she had done and suffered everything; for the people, she had done nothing. Her powerful influence had at all times been directed by her emotions; and if we should carry the study to the end of the Empire, bringing into review all the consorts and female associates of the emperors, this would still be the summary of the story of the Roman woman in politics.
