It is admitted that no small share of the happiness of this period was due to the firmness of the honest Burrus, and the wise, high-minded precepts of Seneca. They deserve the amplest gratitude and credit for this happy interregnum, for they had no easy task to perform. Besides the difficulties which arose from the base and frivolous character of their pupil, besides the infinite delicacy which was requisite for the restraint of a youth who was absolute master of such gigantic destinies, they had the task of curbing the wild and imperious ambition of Agrippina, and of defeating the incessant intrigues of her many powerful dependents. Agrippina had no doubt persuaded herself that her crimes had been mainly committed in the interest of her son; but her conduct showed that she wished him to be a mere instrument in her hands. She wished to govern him, and had probably calculated on doing so by the assistance of Seneca, just as our own Queen Caroline completely managed George II. with the aid of Sir Robert Walpole. She rode in a litter with him; without his knowledge she ordered the poisoning of M. Silanus, a brother of her former victim, she goaded Narcissus to death, against his will; through her influence the Senate was sometimes assembled in the palace, and she took no pains to conceal from the senators that she was herself seated behind a curtain where she could hear every word of their deliberations;--nay, on one occasion, when Nero was about to give audience to an important Armenian legation, she had the audacity to enter the audience-chamber, and advance to take her seat by the side of the Emperor. Every one else was struck dumb with amazement, and even terror, at a proceeding so unusual; but Seneca, with ready and admirable tact, suggested to Nero that he should rise and meet his mother, thus obviating a public scandal under the pretext of filial affection.
