[138] But now a multitude of Germans had surrounded the theater with their swords drawn: all the spectators looked for nothing but death, and at every one coming in a fear seized upon them, as if they were to be cut in pieces immediately; and in great distress they were, as neither having courage enough to go out of the theater, nor believing themselves safe from dangers if they tarried there. And when the Germans came upon them, the cry was so great, that the theater rang again with the entreaties of the spectators to the soldiers, pleading that they were entirely ignorant of every thing that related to such seditious contrivances, and that if there were any sedition raised, they knew nothing of it; they therefore begged that they would spare them, and not punish those that had not the least hand in such bold crimes as belonged to other persons, while they neglected to search after such as had really done whatsoever it be that hath been done. Thus did these people appeal to God, and deplore their infelicity with shedding of tears, and beating their faces, and said every thing that the most imminent danger and the utmost concern for their lives could dictate to them. This brake the fury of the soldiers, and made them repent of what they minded to do to the spectators, which would have been the greatest instance of cruelty. And so it appeared to even these savages, when they had once fixed the heads of those that were slain with Asprenas upon the altar; at which sight the spectators were sorely afflicted, both upon the consideration of the dignity of the persons, and out of a commiseration of their sufferings; nay, indeed, they were almost in as great disorder at the prospect of the danger themselves were in, seeing it was still uncertain whether they should entirely escape the like calamity. Whence it was that such as thoroughly and justly hated Caius could yet no way enjoy the pleasure of his death, because they were themselves in jeopardy of perishing together with him; nor had they hitherto any firm assurance of surviving.
