Sejanus had in fact formed the daring project of destroying Tiberius and his family, and seizing the supreme power. As besides Tiberius and Drusus, who had two sons, there were a brother and three sons of Germanicus living, he resolved, as the safer course, to remove them gradually by art and treachery. He began with Drusus, against whom he had a personal spite, as that violent youth had one time publicly given him a blow in the face. In order to effect his purpose, he seduced his wife Livia or Livilla, the sister of Germanicus; and then, by holding out to her the prospect of a share in the imperial power, he induced her to engage in the plan for the murder of her husband. Her physician Eudemus was also taken into the plot, but it was some time before the associates could finally determine what mode to adopt. At length a slow poison was fixed on, which was administered to Drusus by a eunuch named Lygdus, and he died apparently of disease (23). Tiberius, who while his son was lying dead, had entered the senate house and addressed the members with his usual composure, pronounced the funeral oration himself, and then turned to business for consolation. So far all had succeeded with Sejanus, and death carried off the younger son of Drusus soon after his father; but Nero and Drusus, the two elder sons of Germanicus, were now growing up, and the chastity of their mother and the fidelity of those about them put poison out of the question. He therefore adopted another course; and taking advantage of the high spirit of Agrippina, and working on the jealousy of her which Augusta was known to entertain, he managed so that both she and Livia should labour to prejudice Tiberius against Agrippina by talking of the pride which she took in her progeny, and the ambitious designs which she entertained. At the same time he induced some of those about her to stimulate her haughty spirit by their treacherous language. He further proposed to deprive her of support by destroying those persons of influence who were attached to her family, or the memory of her husband. With this view he selected for his first victims C. Silius and Titius Sabinus, the friends of Germanicus, and Silius’ wife, Sosia Galla, to whom Agrippina was strongly attached, and who was therefore an object of dislike to Tiberius. Omitting however Sabinus for the present, he caused the consul Visellius Varro to accuse Silius of treason for having dissembled his knowledge of the designs of Sacrovir, having disgraced his victory by his avarice, and countenanced the acts of his wife. Having vainly asked for a delay till his accuser should go out of office, and seeing that Tiberius was determinedly hostile to him, Silius avoided a condemnation by a voluntary death. His wife was banished; a portion of his property was confiscated, but the remainder was left to his children. [Sidenote: [24-25 A.D.]]
