After much debate, and many consultations in respect to the best course to be pursued, it was decided to accept the offer of a certain Subrius Flavius, who undertook to kill the emperor in the streets, at night, at some time when he was roaming about in his carousals. Flavius, in fact, was very daring and resolute in his proposals, though wanting, as it proved in the end, in the fulfillment of them. He offered to stab Nero in the theater, when he was singing on the stage, in the midst of all the thousands of spectators convened there. This the conspirators thought, it seems, an unnecessarily bold and desperate mode of accomplishing the end in view, and the plan was accordingly overruled. Flavius then proposed to set the palace on fire some night when Nero was out in the city, and then, in the confusion that would ensue, and while the attention of the guards who had accompanied Nero should be drawn toward the fire, to assassinate the emperor in the streets. This plan was acceded to by the conspirators, and it was left to Flavius to select a favorable time for the execution of it.
Time passed on, however, and nothing was done. The favorable time which Flavius looked for did not appear. In the meanwhile Epicharis became more and more impatient of the delay. She urged the conspirators to do their work, and chided in the strongest terms their irresolution and pusillanimity. At length finding that her invectives and reproaches were of no avail, she determined to leave them, and to see what she could do herself toward the attainment of the end.
She accordingly left Rome and proceeded southwardly along the coast till she came to Misenum, which, as has already been said, was the great naval station of the empire at this time. Epicharis went to some of the officers of the fleet, many of whom she knew,-and in a very secret and cautious manner made known to them the nature of the plot which had been formed at Rome for the destruction of Nero and the elevation of Piso to the empire in his stead. Before, however, communicating intelligence of the conspiracy to any persons whatever, Epicharis would converse with them secretly and confidentially to learn how they were affected toward Nero and his government. If she found them well disposed she said nothing. If on the other hand any one appeared discontented with the government, or hostile to it in any way, she would cautiously make known to him the plans which were concocting at Rome for the overthrow of it. She took care, however, in these conversations to have never more than one person present with her at a time, and she revealed none of the names of the conspirators.
Among the other officers of the fleet was a certain Proculus, who was one of the first with whom Epicharis communicated. Proculus was one of the men who had been employed by Nero in his attempts to assassinate Agrippina his mother, and for his services on that occasion had been promoted to the command of a certain number of ships, a number containing in all one thousand men. This promotion, however, as Epicharis found when she came to converse with him, Proculus did not consider as great a reward as his services had deserved. The perpetration of so horrible a crime as the murder of the emperor's mother, merited, in his opinion, as he said to Epicharis, a much higher recompense than the command of a thousand men. Epicharis thought so too. She talked with Proculus about his wrongs, and the injuries which he suffered from Nero's ingratitude and neglect, until she fancied that he was in a state of mind which would prepare him to join in the plans of the conspirators, and then she cautiously unfolded them to him.
Proculus listened with great apparent interest to Epicharis's communication, and pretended to enter very cordially into the plan of the conspiracy; but as soon as the interview was ended he immediately left Misenum, and proceeded immediately to Rome, where he divulged the whole design to Nero.
Nero was exceedingly alarmed, and sent officers off at once to seize Epicharis and bring her before him. Epicharis, when questioned and confronted with Proculus, resolutely denied that she had ever held any such conversation with Proculus as he alledged, and feigned the utmost astonishment at what she termed the impudence of his accusation. She called for witnesses and proofs. Proculus of course could produce none, for Epicharis had taken care that there should be no third person present at their interviews. Proculus could not even give the names of any of the conspirators at Rome. He could only persist in his declaration that Epicharis had really disclosed to him the existence of the conspiracy, and had proposed to him to join in it; while she on the contrary as strenuously and positively denied it. Nero was perplexed. He found it impossible to determine what to believe. He finally dismissed Proculus, and sent Epicharis to prison, intending that she should remain there until he could make a more full examination into the case, and determine what to do.
In the mean time the conspirators became considerably alarmed when they heard of the arrest of Epicharis, and though they knew that thus far she had revealed nothing, they could not tell how soon her fidelity and firmness might yield under the tortures to which she was every day liable to be subjected; and as there appeared to be now no prospect that Flavius would ever undertake to execute his plan, they began to devise some other means of attaining the end.
It seems that Piso possessed at this time a villa and country-seat at Baiæ, on the coast south of Rome, and near to Misenum, and that Nero was accustomed sometimes to visit Piso here. It was now proposed by some of the conspirators that Piso should invite Nero to visit him at this villa, as if to witness some spectacles or shows which should be arranged for his entertainment there, and that then persons employed for the purpose should suddenly assassinate him, when off his guard, in the midst of some scene of convivial pleasure. Piso, however, objected to this plan. He conceived, he said, that it would be dishonorable in him to commit an act of violence upon a guest whom he had invited under his roof, as his friend. He was willing to take his full share of the responsibility of destroying the tyrant in any fair and manly way, but he would not violate the sacred rites of hospitality to accomplish the end.
So this plan was abandoned. It was supposed, however, that Piso had another and a deeper reason for his unwillingness that Nero should be assassinated at Baiæ than his regard for his honor as a host. He thought, it was said, that it would not be safe for him to be away from Rome when the death of Nero should be proclaimed in the capitol, lest some other Roman nobleman or great officer of state should suddenly arise in the emergency and assume the empire. There were, in fact, one or two men in Rome of great power and influence, of whom Piso was specially jealous and he was naturally very much disposed to be on his guard against opening any door of opportunity for them to rise to power. To commit a great crime in order to secure his own aggrandizement, and yet to manage the commission of it in such a way as not only to shut himself off from the expected benefit, but to secure that benefit to a hated rival, would have been a very fatal misstep. So the plan of destroying Nero at Baiæ was overruled.
At length one more, and as it proved a final scheme, was formed for accomplishing the purpose of the conspiracy. It was determined to execute Nero in Rome, at a great public celebration which was then about to take place. It seems that it was sometimes customary in ancient times for persons who had any request or petition to make to an emperor or king, to avail themselves of the occasion of such celebrations to present them. Accordingly it was determined that Lateranus should approach Nero at a certain time during the celebration of the games, as if to offer a petition,-the other conspirators being close at hand, and ready to act at a moment's warning. Lateranus, as soon as he was near enough, was to kneel down and suddenly draw the emperor's robes about his feet, and then clasp the feet thus enveloped, in his arms, so as to render Nero helpless. The other conspirators were then to rush forward and kill their victim with their daggers. In the mean time while Lateranus and his associates were perpetrating this deed in the circus where the games were to be exhibited, Piso was to station himself in a certain temple not far distant, to await the result; while Fenius, the officer of the guard, who has already been mentioned as the chief military reliance of the conspirators, was to be posted in another part of the city, with a military cavalcade in array, ready to proceed through the streets and bring Piso forth to be proclaimed emperor as soon as he should receive the tidings that Nero had been slain. It is said that in order to give additional éclat and popularity to the proceeding, it was arranged that Octavia, a daughter of Claudius, the former emperor, was to be brought forward with Piso in the cavalcade, as if to combine the influence of her hereditary claims, whatever they might be, with the personal popularity of Piso in favor of the new government about to be established.
