Of course while passing through this scene the mind of Chærea was in a tumult of agitation and excitement,-the anguish of mind which he must have felt in his compassion for the sufferer, mingling and contending with the desperate indignation which burned in his bosom against the author of all these miseries. He was wrought up, in fact, to such a state of frenzy by this transaction, that as soon as it was over he determined immediately to take measures to put Caligula to death. This was a very bold and desperate resolution. Caligula was the greatest and most powerful potentate on earth. Chærea was only a captain of his guard, without any political influence or power, and with no means whatever of screening himself from the terrible consequences which might be expected to follow from his attempt, whether it should succeed or fail.
So thoroughly, however, was he now aroused, that he determined to brave every danger in the attainment of his end. He immediately began to seek out among the officers of the army such men as he supposed would be most likely to join him,-men of courage, resolution, and faithfulness, and those who, from their general character or from the wrongs which they had individually endured from the government, were to be supposed specially hostile to Caligula's dominion. From among these men he selected a few, and to them he cautiously unfolded his designs. All approved of them. Some, it is true, declined taking any active part in the conspiracy, but they assured Chærea of their good wishes, and promised solemnly not to betray him.
The number of the conspirators daily increased. There was, however, at their meetings for consultation, some difference of opinion in respect to the course to be pursued. Some were in favor of acting promptly and at once. The greatest danger which was to be apprehended, they thought, was in delay. As the conspiracy became extended, some one would at length come to the knowledge of it, they said, who would betray them. Others, on the other hand, were for proceeding cautiously and slowly. What they most feared was rash and inconsiderate action. It would be ruinous to the enterprise, as they maintained, for them to attempt to act before their plans were fully matured.
Chærea was of the former opinion. He was very impatient to have the deed performed. He was ready himself, he said, to perform it, at any time; his personal duties as an officer of the guard, gave him frequent occasions of access to the emperor, and he was ready to avail himself of any of them to kill the monster. The emperor went often, he said, to the capitol, to offer sacrifices, and he could easily kill him there. Or, if they thought that that was too public an occasion, he could have an opportunity in the palace, at certain religious ceremonies which the emperor was accustomed to perform there, and at which Chærea himself was usually present. Or, he was ready to throw him down from a tower where he was accustomed to go sometimes for the purpose of scattering money among the populace below. Chærea said that he could easily come up behind him on such an occasion, and hurl him suddenly over the parapet down to the pavement below. All these plans, however, seemed to the conspirators too uncertain and dangerous, and Chærea's proposals were accordingly not agreed to.
At length, the time drew near when Caligula was to leave Rome to proceed to Alexandria in Egypt, and the conspirators perceived that they must prepare to act, or else abandon their design altogether. It had been arranged that there was to be a grand celebration at Rome previous to the emperor's departure. This celebration, which was to consist of games, and sports, and dramatic performances of various kinds, was to continue for three days, and the conspirators determined, after much consultation and debate, that Caligula should be assassinated on one of those days.
After coming to this conclusion, however, in general, their hearts seemed to fail them in fixing the precise time for the perpetration of the deed, and two of the three days passed away accordingly without any attempt being made. At length, on the morning of the third day, Chærea called the chief conspirators together, and urged them very earnestly not to let the present opportunity pass away. He represented to them how greatly they increased the danger of their attempts by such delays, and he seemed himself so full of determination and courage, and addressed them with so much eloquence and power, that he inspired them with his own resolution, and they decided unanimously to proceed.
The emperor came to the theater that day at an unusually early hour, and seemed to be in excellent spirits and in an excellent humor. He was very complaisant to all around him, and very lively, affable, and gay. After performing certain ceremonies, by which it devolved upon him to open the festivities of the day, he proceeded to his place, with his friends and favorites about him, and Chærea, with the other officers that day on guard, at a little distance behind him.
The performances were commenced, and every thing went on as usual until toward noon. The conspirators kept their plans profoundly secret, except that one of them, when he had taken his seat by the side of a distinguished senator, asked him whether he had heard any thing new. The senator replied that he had not. "I can then tell you something," said he, "which perhaps you have not heard, and that is, that in the piece which is to be acted to-day, there is to be represented the death of a tyrant." "Hush!" said the senator, and he quoted a verse from Homer, which meant, "Be silent, lest some Greek should overhear."
It had been the usual custom of the emperor, at such entertainments, to take a little recess about noon, for rest and refreshments. It devolved upon Chærea to wait upon him at this time, and to conduct him from his place in the theater to an adjoining apartment in his palace which was connected with the theater, where there was provided a bath and various refreshments. When the time arrived, and Chærea perceived, as he thought, that the emperor was about to go, he himself went out, and stationed himself in a passage-way leading to the bath, intending to intercept and assassinate the emperor when he should come along. The emperor, however, delayed his departure, having fallen into conversation with his courtiers and friends, and finally he said that, on the whole, as it was the last day of the festival, he would not go out to the bath, but would remain in the theater; and then ordering refreshments to be brought to him there, he proceeded to distribute them with great urbanity to the officers around him.
In the mean time, Chærea was patiently waiting in the passage-way, with his sword by his side, all ready for striking the blow the moment that his victim should appear. Of course the conspirators who remained behind were in a state of great suspense and anxiety, and one of them, named Minucianus, determined to go out and inform Chærea of the change in Caligula's plans. He accordingly attempted to rise, but Caligula put his hand upon his robe, saying, "Sit still, my friend. You shall go with me presently." Minucianus accordingly dissembled his anxiety and agitation of mind still a little longer, but presently, watching an opportunity when the emperor's attention was otherwise engaged, he rose, and, assuming an unconcerned and careless air, he walked out of the theater.
He found Chærea in his ambuscade in the passage-way, and he immediately informed him that the emperor had concluded not to come out. Chærea and Minucianus were then greatly at a loss what to do. Some of the other conspirators, who had followed Minucianus out, now joined them, and a brief but very earnest and solemn consultation ensued. After a moment's hesitation, Chærea declared that they must now go through with their work at all hazards, and he professed himself ready, if his comrades would sustain him in it, to go back to the theater, and stab the tyrant there in his seat, in the midst of his friends. Minucianus and the others concurred in this design, and it was resolved immediately to execute it.
