There were however obstacles to his ambition in the imperial house with its many princes, a son in youthful manhood and grown-up grandsons. As it would be unsafe to sweep off such a number at once by violence, while craft would necessitate successive intervals in crime, he chose, on the whole, the stealthier way, and to begin with Drusus, against whom he had the stimulus of a recent resentment. Drusus, who could not brook a rival and was somewhat irascible, had, in a casual dispute, raised his fist at Sejanus, and, when he defended himself, had struck him in the face. On considering every plan, Sejanus thought his easiest revenge was to turn his attention to Livia, Drusus's wife. She was a sister of Germanicus, and though she was not handsome as a girl, she became a woman of surpassing beauty. Pretending an ardent passion for her, he seduced her, and having won his first infamous triumph, and assured that a woman after having parted with her virtue will hesitate at nothing, he lured her on to thoughts of marriage, of a share in sovereignty, and of her husband's destruction. And she, the niece of Augustus, the daughter-in-law of Tiberius, the mother of children by Drusus, for a provincial paramour, foully disgraced herself, her ancestors, and her descendants, giving up honour and a sure position for prospects as base as they were uncertain. They took into their confidence Eudemus, Livia's friend and physician, whose profession was a pretext for frequent secret interviews. Sejanus, to avert his mistress's jealousy, divorced his wife Apicata, by whom he had had three children. Still the magnitude of the crime caused fear and delay, and sometimes a conflict of plans.
