[Illustration: Britannicus.]

In order to understand how wise and reasonable the conduct of Agrippina really was, we must also remember that Nero was four years older than Britannicus, and that, therefore, in the year 50, when Nero was adopted, Britannicus was a mere lad of nine. As Claudius was already sixty, it would have been most imprudent to designate a nine-year-old lad as his only possible successor, when Nero, who was four years his senior, would have been better prepared than Britannicus to take up the reign. There is a further proof that Agrippina had no thought of destroying the race of Claudius and Messalina, for before his adoption she had married Nero to Octavia, the daughter of the imperial pair. Octavia was a woman possessed of all the virtues which the ancient Roman nobility had cherished. She was chaste, modest, patient, gentle, and unselfish, and she would be able to assist in strengthening the power of her house. Agrippina had therefore, in the ancient manner, affianced the young pair at an early age, and hoped that she might make a couple which would serve as an example to the families of the aristocracy.

In short, Agrippina, far from seeking to weaken the imperial house by destroying the descendants of Messalina, was attempting to bring her son into the family precisely for the purpose of giving it strength. And, sensible woman that she was, she could hardly have acted otherwise. She had seen the family of Augustus, once so prosperous, reduced to a state of exhaustion and virtually destroyed by the fatal discord between her mother and Tiberius and the quarrels between her brothers. The state had suffered greatly through the madness of Caligula and the reckless hatred of the first Agrippina, and the present empress, her daughter, who was not merely fond of her son, but endowed in addition with the gift of reflection, sought as far as possible to make amends for the evils which had unconsciously been wrought. The hopes of the future were henceforth to abide in Britannicus and in Nero. In Agrippina there reappeared the wisdom of her greatest predecessors, and the people were so well satisfied that they conferred upon her the very highest honor, such as in her time even Livia herself had not received. She was given the title Augusta; she was allowed to ride into the precincts of the Capitol in a gilded coach (carpentum), though this was an honor which in old time had been conceded only to priests and to the images of the gods. This last descendant of Livia and Drusus, in whom the virtues of a venerated past seemed to reappear, was surrounded by a semi-religious adoration. This is an evidence of sincere and profound respect, for though the Romans often showered marks of human adulation upon their potentates, it was not often that they bestowed honors of so sacred a character.

The unforeseen death of Claudius suddenly cut short the work which Agrippina had well under way. Claudius was sixty-four years old, and one night in the month of October of the year 54 he succumbed to some mysterious malady after a supper of which, as usual, he had partaken inordinately. Tacitus pretends to know that Agrippina had secretly administered poison to Claudius in a plate of mushrooms. During the night, however, fearing lest Claudius would survive, she had called Claudius's physician, Xenophon, who was a friend of hers. The latter, while pretending to induce vomiting, had painted his throat with a feather dipped in a deadly poison, and had killed him. This version is so strange and improbable that Tacitus himself does not dare affirm it, but says that "many believe" that it was in this manner that Claudius met his death. But if there are still people credulous enough to believe that the head of a great state can be poisoned in the twinkling of an eye by a doctor who brushes his throat with a feather, it is more difficult to understand what grounds Agrippina could have had for poisoning her husband. According to Tacitus, it was because she was disturbed by the fact that Claudius had for some time shown that he preferred Britannicus to Nero; but even if the fact were true, as a motive it would be ridiculous. Augustus was much fonder of Germanicus than he was of Tiberius; and yet at his death the senate chose Tiberius, and not Germanicus, because at that moment the situation clearly called for the former as head of the empire. When Claudius died, Britannicus was thirteen and Nero seventeen years old. They were both, therefore, mere lads, and it was most probable that if the imperial seat fell vacant, the senate would choose neither, since they were both too young and inexperienced. This is so true that other historians have supposed, on the contrary, that Agrippina had fallen out with some one of the more powerful freedmen of Claudius, and seeing Claudius waver, had despatched him in order that she herself should not end like Messalina. But this hypothesis also is absurd. An empress was virtually invulnerable. Messalina had proved this, for she had committed every excess and abuse with impunity. Agrippina, protected as she was by the respect of all, invested with honors that gave her person a virtually sacred character, had nothing to fear either from the weak Claudius or from his powerful freedmen.

This accusation of poisoning, therefore, seems to be of precisely the same sort as, and not a whit more serious than, all those other similar accusations which were brought against the members of the Augustan family. Claudius, who was already sixty-four, in all probability died a sudden but natural death, and from the point of view of the interests of the house of Augustus, which Agrippina had strongly at heart, he died much too soon. It was a dangerous and difficult matter to ask the Roman senate to appoint one of these striplings commander of the armies and emperor, even though they were the only survivors of the race of Augustus. So true is this that Tacitus tells us that Agrippina kept the death of Claudius secret for many hours and pretended that the physicians were still struggling to save him, when in reality he was already dead, dum res firmando Neronis imperio componuntur (while matters were being arranged to assure the empire to Nero). Consequently, if everything had to be hurried through in confusion at the last moment, it is plain that Agrippina herself must have been taken by surprise by the illness and death of Claudius. She therefore cannot be held responsible for having caused it.

It is not, however, difficult to reconstruct the course of events. On the nights of the twelfth and thirteenth of October, soon after Claudius had been suddenly stricken down by his violent malady, the doctors announced to Agrippina that the emperor was lost. Agrippina immediately understood that since the family of Augustus could at that moment present no full-grown man as candidate for the imperial office, there was grave danger that the senate might refuse to confer the supreme power either upon Nero or Britannicus. The only means of avoiding this danger was to bring pressure to bear upon the senate through the pretorian cohorts, which were as friendly to the family of Augustus as the senate was hostile. She must present one of the two youths to the guards and have him acclaimed not head of the empire, but head of the armies. The senate would thereby be constrained to proclaim him head of the empire, as they had done in the case of Claudius.

But which one of the two youths was it best to choose, Claudius's son by blood or his son by adoption? Nero was chosen as the result of the unrighteous ambition of Agrippina, so Tacitus says. It is very probable that Agrippina was more eager to see her own son at the head of the empire than to see Britannicus there; but this does not seem to have been the real reason of her choice, for it could not have been otherwise, even if Agrippina had detested Nero and had cherished Britannicus with a maternal affection. Nero was four years older than Britannicus, and therefore he had to be given the preference over the latter. It was a very bold move to propose that the senate make a youth of seventeen emperor; it would have been nothing less than folly to ask that they accept a thirteen-year-old lad as commander-in-chief of the imperial armies of Rome.

Through the help of Seneca and Burrhus, the plan developed by Agrippina was carried out with rapidity and success. On the thirteenth of October, after matters had been arranged with the troops, the doors of the imperial palace were thrown open at noon; Nero, accompanied by Burrhus, advanced to the cohort which was on guard. He was received with joyous welcome, placed in a litter, borne to the quarters of the pretorians, and acclaimed head of the army. The senate grudgingly confirmed his election. There resulted in Rome a most extraordinary situation: a youth of seventeen, educated in the antique manner, and, though already married, still entirely under the tutelage of a strict mother, had been elevated to the highest position in the immense empire. He was ignorant of the luxury, pleasure, and elegance which were becoming general in the great families; outside of a lively disposition and docility toward his mother, he had up to this point shown no special quality, and no particular vice. Only one peculiarity had been noticed in him: he had studied with great zest music, painting, sculpture, and poetry, and had made himself proficient in these arts, which were considered frivolous and useless for a Roman noble. On the contrary, he had neglected oratory, which was held a necessary art by an aristocracy like the Roman, whose duty it was to use speech at councils, in the tribunals, and in the senate, just as it used the sword on the fields of battle. But the majority believed that this was merely a passing caprice of youth.
