It was charged on Lepida that she had made attempts on the Emperor's consort by magical incantations, and was disturbing the peace of Italy by an imperfect control of her troops of slaves in Calabria.She was for this sentenced to death, notwithstanding the vehement opposition of Narcissus, who, as he more and more suspected Agrippina, was said to have plainly told his intimate friends that "his destruction was certain, whether Britannicus or Nero were to be emperor, but that he was under such obligations to Claudius that he would sacrifice life to his welfare.Messalina and Silius had been convicted, and now again there were similar grounds for accusation.If Nero were to rule, or Britannicus succeed to the throne, he would himself have no claim on the then reigning sovereign.Meanwhile, a stepmother's treacherous schemes were convulsing the whole imperial house, with far greater disgrace than would have resulted from his concealment of the profligacy of the emperor's former wife.Even as it was, there was shamelessness enough, seeing that Pallas was her paramour, so that no one could doubt that she held honour, modesty and her very person, everything, in short, cheaper than sovereignty."This, and the like, he was always saying, and he would embrace Britannicus, expressing earnest wishes for his speedy arrival at a mature age, and would raise his hand, now to heaven, now to the young prince, with entreaty that as he grew up, he would drive out his father's enemies and also take vengeance on the murderers of his mother.
Under this great burden of anxiety, he had an attack of illness, and went to Sinuessa to recruit his strength with its balmy climate and salubrious waters.Thereupon, Agrippina, who had long decided on the crime and eagerly grasped at the opportunity thus offered, and did not lack instruments, deliberated on the nature of the poison to be used.The deed would be betrayed by one that was sudden and instantaneous, while if she chose a slow and lingering poison, there was a fear that Claudius, when near his end, might, on detecting the treachery, return to his love for his son.She decided on some rare compound which might derange his mind and delay death.A person skilled in such matters was selected, Locusta by name, who had lately been condemned for poisoning, and had long been retained as one of the tools of despotism.By this woman's art the poison was prepared, and it was to be administered by an eunuch, Halotus, who was accustomed to bring in and taste the dishes.
All the circumstances were subsequently so well known, that writers of the time have declared that the poison was infused into some mushrooms, a favourite delicacy, and its effect not at the instant perceived, from the emperor's lethargic, or intoxicated condition.His bowels too were relieved, and this seemed to have saved him.Agrippina was thoroughly dismayed.Fearing the worst, and defying the immediate obloquy of the deed, she availed herself of the complicity of Xenophon, the physician, which she had already secured.Under pretence of helping the emperor's efforts to vomit, this man, it is supposed, introduced into his throat a feather smeared with some rapid poison; for he knew that the greatest crimes are perilous in their inception, but well rewarded after their consummation.
Meanwhile the Senate was summoned, and prayers rehearsed by the consuls and priests for the emperor's recovery, though the lifeless body was being wrapped in blankets with warm applications, while all was being arranged to establish Nero on the throne.At first Agrippina, seemingly overwhelmed by grief and seeking comfort, clasped Britannicus in her embraces, called him the very image of his father, and hindered him by every possible device from leaving the chamber.She also detained his sisters, Antonia and Octavia, closed every approach to the palace with a military guard, and repeatedly gave out that the emperor's health was better, so that the soldiers might be encouraged to hope, and that the fortunate moment foretold by the astrologers might arrive.
At last, at noon on the 13th of October, the gates of the palace were suddenly thrown open, and Nero, accompanied by Burrus, went forth to the cohort which was on guard after military custom.There, at the suggestion of the commanding officer, he was hailed with joyful shouts, and set on a litter.Some, it is said, hesitated, and looked round and asked where Britannicus was; then, when there was no one to lead a resistance, they yielded to what was offered them.Nero was conveyed into the camp, and having first spoken suitably to the occasion and promised a donative after the example of his father's bounty, he was unanimously greeted as emperor.The decrees of the Senate followed the voice of the soldiers, and there was no hesitation in the provinces.Divine honours were decreed to Claudius, and his funeral rites were solemnized on the same scale as those of Augustus; for Agrippina strove to emulate the magnificence of her great-grandmother, Livia.But his will was not publicly read, as the preference of the stepson to the son might provoke a sense of wrong and angry feeling in the popular mind.
