being engaged in a plot against him, he put to death Antonia, Claudius's daughter, who refused to marry him after the death of Poppaea. In the same way, he destroyed all who were allied to him either by blood or marriage; amongst whom was young Aulus Plautinus. He first compelled him to submit to his unnatural lust, and then ordered him to be executed, crying out, "Let my mother bestow her kisses on my successor thus defiled;" pretending that he had been his mothers paramour, and by her encouraged to aspire to the empire. His step-son, Rufinus Crispinus, Poppaea's son, though a minor, he ordered to be drowned in the sea, while he was fishing, by his own slaves, because he was reported to act frequently amongst his play-fellows the part of a general or an emperor. He banished Tuscus, his nurse's son, for presuming, when he was procurator of Egypt, to wash in the baths which had been constructed in expectation of his own coming. Seneca, his preceptor, he forced to kill himself [609], though, upon his desiring leave to retire, and offering to surrender his estate, he solemnly swore, "that there was no foundation for his suspicions, and that he would perish himself sooner than hurt him." Having promised Burrhus, the pretorian prefect, a remedy for a swelling in his throat, he sent him poison. Some old rich freedmen of Claudius, who had formerly not only promoted (366) his adoption, but were also instrumental to his advancement to the empire, and had been his governors, he took off by poison given them in their meat or drink.
