Nero accordingly avoided secret interviews with her, and when she withdrew to her gardens or to her estates at Tusculum and Antium, he praised her for courting repose. At last, convinced that she would be too formidable, wherever she might dwell, he resolved to destroy her, merely deliberating whether it was to be accomplished by poison, or by the sword, or by any other violent means. Poison at first seemed best, but, were it to be administered at the imperial table, the result could not be referred to chance after the recent circumstances of the death of Britannicus. Again, to tamper with the servants of a woman who, from her familiarity with crime, was on her guard against treachery, appeared to be extremely difficult, and then, too, she had fortified her constitution by the use of antidotes. How again the dagger and its work were to be kept secret, no one could suggest, and it was feared too that whoever might be chosen to execute such a crime would spurn the order.
An ingenious suggestion was offered by Anicetus, a freedman, commander of the fleet at Misenum, who had been tutor to Nero in boyhood and had a hatred of Agrippina which she reciprocated. He explained that a vessel could be constructed, from which a part might by a contrivance be detached, when out at sea, so as to plunge her unawares into the water. "Nothing, he said, "allowed of accidents so much as the sea, and should she be overtaken by shipwreck, who would be so unfair as to impute to crime an offence committed by the winds and waves? The emperor would add the honour of a temple and of shrines to the deceased lady, with every other display of filial affection."
