The several reigns from the death of Augustus present us with uncommon scenes of cruelty and horror; but it was reserved for that of Nero to exhibit to the world the atrocious act of an emperor deliberately procuring the death of his mother. Julia Agrippina was the daughter of Germanicus, and married Domitius Aenobarbus, by whom she had Nero. At the death of Messalina she was a widow; and Claudius, her uncle, entertaining a design of entering again into the married state, she aspired to an incestuous alliance with him, in competition with Lollia Paulina, a woman of beauty and intrigue, who had been married to C. Caesar. The two rivals were strongly supported by their (383) respective parties; but Agrippina, by her superior interest with the emperor's favourites, and the familiarity to which her near relation gave her a claim, obtained the preference; and the portentous nuptials of the emperor and his niece were publicly solemnized in the palace. Whether she was prompted to this flagrant indecency by personal ambition alone, or by the desire of procuring the succession to the empire for her son, is uncertain; but there remains no doubt of her having removed Claudius by poison, with a view to the object now mentioned. Besides Claudius, she projected the death of L. Silanus, and she accomplished that of his brother, Junius Silanus, by means likewise of poison. She appears to have been richly endowed with the gifts of nature, but in her disposition intriguing, violent, imperious, and ready to sacrifice every principle of virtue, in the pursuit of supreme power or sensual gratification. As she resembled Livia in the ambition of a mother, and the means by which she indulged it, so she more than equalled her in the ingratitude of an unnatural son and a parricide. She is said to have left behind her some memoirs, of which Tacitus availed himself in the composition of his Annals.
