[157] Now by this time the people in the theatre were arisen from their seats, and those that were within made a very great disturbance; the cause of which was this, that the spectators were too hasty in getting away. There was also one Aleyon, a physician, who hurried away, as if to cure those that were wounded, and under that pretense he sent those that were with him to fetch what things were necessary for the healing of those wounded persons, but in reality to get them clear of the present dangers they were in. Now the senate, during this interval, had met, and the people also assembled together in the accustomed form, and were both employed in searching after the murderers of Caius. The people did it very zealously, but the senate in appearance only; for there was present Valerius of Asia, one that had been consul; this man went to the people, as they were in disorder, and very uneasy that they could not yet discover who they were that had murdered the emperor; he was then earnestly asked by them all who it was that had done it. He replied, "I wish I had been the man." The consuls ¹ also published an edict, wherein they accused Caius, and gave order to the people then got together, and to the soldiers, to go home; and gave the people hopes of the abatement of the oppressions they lay under; and promised the soldiers, if they lay quiet as they used to do, and would not go abroad to do mischief unjustly, that they would bestow rewards upon them; for there was reason to fear lest the city might suffer harm by their wild and ungovernable behavior, if they should once betake themselves to spoil the citizens, or plunder the temples. And now the whole multitude of the senators were assembled together, and especially those that had conspired to take away the life of Caius, who put on at this time an air of great assurance, and appeared with great magnanimity, as if the administration of the public affairs were already devolved upon them.
