His grandmother Antonia desiring a private conference with him, he denied the request, unless Macro, commander of the guards, might be present. By affronts of this kind, and ill usage, he was the occasion of her death; but, as some think, not without giving her a dose of poison. He paid not the smallest respect to her memory after her death; and gratified himself at beholding, from his parlour, her funeral pile on fire. His brother Tiberius, who had no expectation of any violence, he despatched, by suddenly sending to him a military tribune for that purpose. He forced Silanus his father-in-law to kill himself, by cutting his throat with a razor. The pretext he alleged for these murders was, that the latter had not followed him upon putting to sea in stormy weather, but stayed behind with the view of seizing the city, if he should have been lost in the voyage. The other, he said, smelt of an antidote, which he had taken to prevent his being poisoned by him; whereas Silanus was only afraid of being seasick, and of the trouble of the voyage; and Tiberius had only made use of a medicine for a habitual cough, which was constantly increasing upon him. As to his successor Claudius, he only saved him to make sport with. He lived in the habit of incest with all his sisters; when one of them, Drusilla, was married to Cassius Longinus, a man of consular rank, he took her from him, and kept her openly as his wife. In a fit of sickness, he by his will appointed her heiress of his estate, and the empire likewise. After her death, he ordered a public mourning for her; during which it was capital for any person to laugh, use the bath, or sup with parents, wife, or children. Being inconsolable under his affliction, he went hastily, and in the night-time, from the city, going through Campania to Syracuse; and then suddenly he returned without shaving his beard, or trimming his hair all that time. Nor did he ever after, in matters of the greatest importance, not even in the assemblies of the people and soldiers, swear any otherwise, than “By the divinity of Drusilla.”
