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.
