It was Agrippina's determination to be empress, in order that her son might be emperor. Some years previous, an astrologer had said of the boy that he would reign, but that he would be the death of his mother. "Let me die, then," said she, "so he but reign."

Her marriage with Claudius would be illegal and incestuous, he being her uncle. But Agrippina aroused the emperor's desire for the match by the endearments for which her relationship provided the opportunity, and the complacent Senate passed an enactment that henceforth such marriages should be lawful. Before the nuptials were celebrated, Agrippina obtained the promise of the hand of Octavia, the daughter of Claudius by Messalina, for her son, thus doubly securing her position; this was done despite the fact that Octavia had already been betrothed to another man. Being thus able to have her way before marriage, it is not wonderful that after that event Claudius should be wholly under his wife's rule. Tacitus says: "From this moment the city assumed a different character, and a woman had the control of everything. She, however, did not, like Messalina, mock and trample upon the interests of the State in the extravagance of her lewdness. The despotism exercised was as thorough as though it were under the direction of a man. In her public conduct she was grave and rigid, frequently haughty and overbearing. No departure was observable in her domestic deportment, unless it were necessary to support her power; but an insatiable thirst for money was veiled under the pretext of its being used to maintain the imperial authority."

As an instance of Agrippina's cruelty, it may be mentioned that she brought about the condemnation of Lollia, who had been her rival for the hand of Claudius, and compelled the unfortunate woman to destroy herself. Calpurnia, another illustrious lady, she also doomed to ruin, for no other reason than that the emperor once made a casual remark upon her beauty.

The advancement of her son was the object ever before the eyes of Agrippina; for this she lived and for the attainment of this consummation she spared no promising effort, whether lawful or otherwise. Through the influence of Pallas, one of the favorite freedmen, she brought it to pass that her son was adopted by the emperor as his own, and the historians aver that as a reward for this service Pallas received favors which belonged solely to Claudius. Step by step, Nero was preferred, and at the same time the son of Messalina and the emperor was depreciated. Britannicus seems to have been a boy of spirit. Because he persisted in addressing her son by the name Ahenobarbus [Brazenbeard], Agrippina placed over him tutors whose duty it was to teach him to respect the decree of the Senate, by which the more honorable name of Nero had been conferred on her offspring. Still, everything did not go forward quite to Agrippina's satisfaction. She found in Narcissus almost as great an enemy as had Messalina, and even the emperor was somewhat uncertain in his favor; on one occasion, he was heard to mutter something to the effect that he seemed fated to suffer the iniquities of his wives, and then to punish them. Nero was now seventeen years of age, and through the shrewd policy of his mother had not only been named by the emperor as his successor, but had been generally recognized as the heir-apparent by the people; it needed only the death of Claudius to raise him to the imperial throne.

New wants create new professions. In despotic governments, the lives of certain persons are often too prolonged in the opinion of others who have their own purposes to pursue, and there never have been lacking those who in such a juncture could make themselves extremely useful. In the time of Agrippina there lived a woman named Locusta, who, as Tacitus informs us, was a famous artist in the mixing of drugs. Her skill seems always to have had for its object, not the cure of patients who were confided to her care, but their judicious taking-off. The above-mentioned historian informs us that Agrippina allowed this woman to employ her art upon Claudius; and as no other writer approximate to that age seeks to purge the empress of this accusation, it must be reckoned to her account. "In fact," says Tacitus, "all the particulars of this transaction were soon afterward so thoroughly known, that the writers of those times are able to recount how the poison was poured into a dish of mushrooms, of which he was particularly fond; but whether it was that his senses were stupefied, or from the wine he had drunk, the effect of the poison was not immediately perceived." Agrippina therefore became dismayed; but as her life was at stake, she thought little of the odium of her present proceedings, and called in the aid of Xenophon the physician, whom she had already implicated in her guilty project. It is believed that he, as if he purposed to assist Claudius in his efforts to vomit, put down his throat a feather besmeared with deadly poison.

After the death of Claudius, Agrippina discovered that the day was ill-omened, so that she hesitated to have her son proclaimed. The fact of the emperor's death was therefore kept a secret for some hours. The people were so far imposed upon that they believed that Claudius was approving and desired to be entertained. Buffoons were Produced, who played their antics and cracked their jokes in the presence of the corpse; the empress, in the meantime, feigning to be overcome with grief, was clasping the young Britannicus in her arms and declaring that he was the very image of his father.

At noon, it being the thirteenth of October in the year 4, the death of Claudius was announced, and Nero was received by the soldiers with shouts of joy. The Senate confirmed his accession, and that night, when the tribune asked the new emperor for the watchword, he gave "the best of mothers."

Claudius, unless the Roman historians are to be considered entirely unworthy of credence, had been murdered by his wife; but, notwithstanding this fact and also that she had despised him while he lived, she hastened to propose his apotheosis as soon as he was dead. How much those divine honors which were decreed to deceased members of the imperial family meant to the Romans may be gathered from the fragments which have been preserved of a satire written by Seneca at this time; the satire also indicates the contempt into which the ancient religion had fallen. Seneca claims that from him who saw Drusilla, the sister of Caligula, ascend into heaven, he derived his information as to what happened in Olympus when "a respectable-looking old man, with shaking head, lame foot, and some kind of threat upon his lips" [Claudius] arrived thither. The Olympian Senate, notwithstanding the labors of Hercules on his behalf, voted that Claudius was not to be admitted.

After the inauguration of Nero's reign, there followed for the Empire five years of what seemed to the people, so accustomed were they to the worst horrors in the name of government, a wise and upright administration. Nero was to a certain extent under the influence of Seneca and Burrhus, men who perhaps were as good as any of their time. Credit must be given Agrippina for having at least selected the best men she could find to take charge of the education of her son. Nevertheless, during those five years occurred her own murder and that of Britannicus. After the death of the latter, Locusta--for whom Nero had found ample employment--was permitted to retire to the enjoyment of the immense wealth with which she had been rewarded for her services to those in power; it was stipulated, however, that she should train other women in the practice of her art.

Agrippina had done and suffered much to secure the Empire for her son; but she never contemplated that he would reign alone while she lived. She expected to occupy a throne by his side. Her officious dominance soon became intolerable to the young emperor. He also fell under the fascination of the beautiful but unprincipled Poppæa, who refused to share his palace with so jealous and imperious a mother-in-law. Bitter must have been the reflections of Agrippina when she found herself not only disappointed of this part of her ambition, but also saw that her son was impatiently awaiting her death. Indeed, he was devising means to bring it to pass; but she who was herself so well practised in the methods of assassination was not an easy victim. The sword was too open a method, and she was believed to have prepared herself, by taking antidotes, against all kinds of poisons. But there was a genius at the court. Anicetus, an enfranchised slave, now commander of the fleet, could construct a vessel that would fall to pieces at sea at any given moment. Agrippina was invited to join her son at Baise. He was all affection and again seemed willing to commit himself to her influence. A magnificent vessel was provided to convey her to and from the villa where he had provided an entertainment. As she was returning over the smooth waters, lighted by the brilliant stars, the roof of the cabin, which had been weighted with lead, suddenly fell in, killing a man who belonged to her train. Agrippina and Aceronia, her woman attendant, escaped from this part of the prearranged accident; but the boat then upsetting, they were thrown into the sea. Aceronia, in order that she might be rescued, cried out that she was the emperor's mother, and she was immediately killed by oars and boathooks in the hands of the crew. Her mistress, however, suspecting at once the real nature of what had taken place, remained quiet, and swam until she was picked up by passing boats and conveyed to her own villa.
