In this period died, in the eighty-sixth year of her age, Livia Drusilla, mother of the emperor, and the relict of Augustus, whom she survived fifteen years. She was the daughter of L. Drusus Calidianus and married Tiberius Claudius Nero, by whom she had two sons, Tiberius and Drusus. The conduct of this lady seems to justify the remark of Caligula, that "she was an Ulysses in a woman's dress." Octavius first saw her as she fled from the danger which threatened her husband, who had espoused the cause of Antony; and though she was then pregnant, he resolved to marry her; whether with her own inclination or not, is left by Tacitus undetermined. To pave the way for this union, he divorced his wife Scribonia, and with the approbation of the Augurs, which he could have no difficulty in obtaining, celebrated (241) his nuptials with Livia. There ensued from this marriage no issue, though much desired by both parties; but Livia retained, without interruption, an unbounded ascendancy over the emperor, whose confidence she abused, while the uxorious husband little suspected that he was cherishing in his bosom a viper who was to prove the destruction of his house. She appears to have entertained a predominant ambition of giving an heir to the Roman empire; and since it could not be done by any fruit of her marriage with Augustus, she resolved on accomplishing that end in the person of Tiberius, the eldest son by her former husband. The plan which she devised for this purpose, was to exterminate all the male offspring of Augustus by his daughter Julia, who was married to Agrippa; a stratagem which, when executed, would procure for Tiberius, through the means of adoption, the eventual succession to the empire. The cool yet sanguinary policy, and the patient perseverance of resolution, with which she prosecuted her design, have seldom been equalled. While the sons of Julia were yet young, and while there was still a possibility that she herself might have issue by Augustus, she suspended her project, in the hope, perhaps, that accident or disease might operate in its favour; but when the natural term of her constitution had put a period to her hopes of progeny, and when the grandsons of the emperor were risen to the years of manhood, and had been adopted by him, she began to carry into execution what she long had meditated. The first object devoted to destruction was C. Caesar Agrippa, the eldest of Augustus's grandsons. This promising youth was sent to Armenia, upon an expedition against the Persians; and Lollius, who had been his governor, either accompanied him thither from Rome, or met him in the East, where he had obtained some appointment. From the hand of this traitor, perhaps under the pretext of exercising the authority of a preceptor, but in reality instigated by Livia, the young prince received a fatal blow, of which he died some time after.
