Nero (for as to Claudius, he came too late to the throne to indulge any propensities of this nature with so little discretion) was but a variety of the same species. He also was an amateur, and an enthusiastic amateur of murder. But as this taste, in the most ingenious hands, is limited and monotonous in its modes of manifestation, it would be tedious to run through the long Suetonian roll-call of his peccadilloes in this way. One only we shall cite, to illustrate the amorous delight with which he pursued any murder which happened to be seasoned highly to his taste by enormous atrocity, and by almost unconquerable difficulty. It would really be pleasant, were it not for the revolting consideration of the persons concerned, and their relation to each other, to watch the tortuous pursuit of the hunter, and the doubles of the game, in this obstinate chase. For certain reasons of state, as Nero attempted to persuade himself, but in reality because no other crime had the same attractions of unnatural horror about it, he resolved to murder his mother Agrippina. This being settled, the next thing was to arrange the mode and the tools. Naturally enough, according to the custom then prevalent in Rome, he first attempted the thing by poison. The poison failed: for Agrippina, anticipating tricks of this kind, had armed her constitution against them, like Mithridates; and daily took potent antidotes and prophylactics. Or else (which is more probable) the emperor's agent in such purposes, fearing his sudden repentance and remorse on first hearing of his mother's death, or possibly even witnessing her agonies, had composed a poison of inferior strength. This had certainly occurred in the case of Britannicus, who had thrown off with ease the first dose administered to him by Nero. Upon which he had summoned to his presence the woman employed in the affair, and compelling her by threats to mingle a more powerful potion in his own presence, had tried it successively upon different animals, until he was satisfied with its effects; after which, immediately inviting Britannicus to a banquet, he had finally dispatched him. On Agrippina, however, no changes in the poison, whether of kind or strength, had any effect; so that, after various trials, this mode of murder was abandoned, and the emperor addressed himself to other plans. The first of these was some curious mechanical device, by which a false ceiling was to have been suspended by bolts above her bed; and in the middle of the night, the bolt being suddenly drawn, a vast weight would have descended with a ruinous destruction to all below. This scheme, however, taking air from the indiscretion of some amongst the accomplices, reached the ears of Agrippina; upon which the old lady looked about her too sharply to leave much hope in that scheme: so _that_ also was abandoned. Next, he conceived the idea of an artificial ship, which, at the touch of a few springs, might fall to pieces in deep water. Such
