Locusta, the reader will remember, was the woman whom Agrippina had employed for the murder of her husband, Claudius. She was still in custody as a convict, being under sentence of death for her crimes. She was in the charge of a certain captain named Pollio, an officer of the Prætorian guard. Nero sent for Pollio, and directed him to procure from his prisoner a poisonous potion suitable for the purpose intended. The potion was prepared, and soon afterward it was administered. At least it was given to certain attendants that were employed about the person of Britannicus, with orders that they should administer it. The expected effect, however, was not produced. Whether it was because the potion which Locusta had prepared was too weak, or because it was not really administered by those who received it in charge, no result followed, and Nero was greatly enraged. He sent for Pollio, and assailed him with reproaches and threats, and as for Locusta, he declared that she should be immediately put to death. They were both miserable cowards, he said, who had not the firmness to do their duty. Pollio, in reply, made the most earnest protestations of his readiness to do whatever his master should command. He assured Nero that the failure of their attempt was owing entirely to some accidental cause, and that if he would give Locusta one more opportunity to make the trial, he would guarantee that she would prepare a mixture that would kill Britannicus as quick as a dagger would do it.

A second attempt.
A second preparation.

Nero ordered that this should immediately be done. Locusta was sent for, and was shut up with Pollio in an apartment adjoining that of the emperor, with directions to make the mixture there, and then to administer it forthwith. Their lives were to depend upon the result. The poison was soon prepared. There was, however, a serious difficulty in the way of administering it, since a potion so sudden and violent in its character as this was intended to be, might be expected to take immediate effect upon the taster, and so produce an alarm which would prevent Britannicus from receiving it. To obviate this difficulty, Pollio and Locusta cunningly contrived the following plan.

Mode of administering the poison.
Britannicus dies.

They mixed the poison when it was prepared, with cold water, and put it in the pitcher in which cold water was customarily kept in the apartment where Britannicus was to take his supper. When the time arrived Nero himself came in and took his place upon a couch which was standing in the room, with a view of watching the proceedings. Some broth was brought in for the prince's supper. The attendant whose duty it was, tasted it as usual, and then passed it into the prince's hand. Britannicus tasted it, and found it too hot. It had been purposely made so. He gave it back to the attendant to be cooled. The attendant took it to the pitcher, and cooled it with the poisoned water, and then gave it back again to Britannicus without asking the taster to taste it again. Britannicus drank the broth. In a few minutes the fatal consequences ensued. The unhappy victim sank suddenly down in a fainting fit. His eyes became fixed, his limbs were paralyzed, his breathing was short and convulsive. The attendants rushed toward him to render him assistance, but his life was fast ebbing away, and before they could recover from the shock which his sudden illness occasioned them, they found that he had ceased to breathe.

Agrippina's agitation and distress.

The event produced, of course, great excitement and commotion throughout the palace. Agrippina was immediately summoned, and as she stood over the dying child she was overwhelmed with terror and distress. Nero, on the other hand, appeared wholly unmoved. "It is only one of his epileptic fits," said he. "Britannicus has been accustomed to them from infancy. He will soon recover."

As soon, however, as there was no longer any room to question that Britannicus was dead, Nero began immediately to make preparations for the burial of the body. The remorse which, notwithstanding his depravity, he could not but feel at having perpetrated such a crime, made him impatient to remove all traces and memorials of it from his sight; and, besides, he was afraid to wait the usual period and then to make arrangements for a public funeral, lest the truth in respect to the death of Britannicus might be suspected by the Romans, and a party be formed to revenge his wrongs. Any tendency of this kind which might exist would be greatly favored, he knew, by the excitement of a public funeral. He determined, therefore, that the body should be immediately buried.

Effect produced by the poison.
Remedy.

There was another reason still for this dispatch. It seems that one of the effects of the species of poison which Locusta had administered was that the body of the victim was turned black by it soon after death. This discoloration, in fact, began to appear in the face of the corpse of Britannicus before the time for the interment arrived; and Nero, in order to guard against the exposure which this phenomenon threatened, ordered the face to be painted of the natural color, by means of cosmetics, such as the ladies of the court were accustomed to use in those days. By doing this the countenance of the dead was restored to its proper color, and afterward underwent no further change. Still the emperor was naturally impatient to have the body interred.
