Tiberius pronounced a panegyric on his son before the Rostra, during which the Senate and people, in appearance rather than in heart, put on the expression and accents of sorrow, while they inwardly rejoiced at the brightening future of the family of Germanicus. This beginning of popularity and the ill-concealed ambition of their mother Agrippina, hastened its downfall. Sejanus when he saw that the death of Drusus was not avenged on the murderers and was no grief to the people, grew bold in wickedness, and, now that his first attempt had succeeded, speculated on the possibility of destroying the children of Germanicus, whose succession to the throne was a certainty. There were three, and poison could not be distributed among them, because of the singular fidelity of their guardians and the unassailable virtue of Agrippina. So Sejanus inveighed against Agrippina's arrogance, and worked powerfully on Augusta's old hatred of her and on Livia's consciousness of recent guilt, and urged both these women to represent to the emperor that her pride as a mother and her reliance on popular enthusiasm were leading her to dream of empire. Livia availed herself of the cunning of accusers, among whom she had selected Julius Postumus, a man well suited to her purpose, as he had an intrigue with Mutilia Prisca, and was consequently in the confidence of Augusta, over whose mind Prisca had great influence. She thus made her aged grandmother, whose nature it was to tremble for her power, irreconcilably hostile to her grandson's widow. Agrippina's friends too were induced to be always inciting her proud spirit by mischievous talk.
