The Annals and the Histories · Ann. 5.9

It was next decided to punish the remaining children of Sejanus, though the fury of the populace was subsiding, and people generally had been appeased by the previous executions. Accordingly they were carried off to prison, the boy, aware of his impending doom, and the little girl, who was so unconscious that she continually asked what was her offence, and whither she was being dragged, saying that she would do so no more, and a childish chastisement was enough for her correction. Historians of the time tell us that, as there was no precedent for the capital punishment of a virgin, she was violated by the executioner, with the rope on her neck. Then they were strangled and their bodies, mere children as they were, were flung down the Gemoniae.
