Ammianus Marcellinus Res Gestae 29.1.25

[25] First, after some unimportant questions, Pergamius was called in, betrayed (as has been said) ¹ by Palladius of having foreknowledge of certain things through criminal incantations. Since he was very eloquent and was prone to say dangerous things, while the judges were in doubt what ought to be asked first and what last, he began to speak boldly, and shouted out in an endless flood the names of a very large number of men as accomplices, demanding that some be produced from all but the ends of the earth, to be accused of great crimes. He, as the contriver of too hard a task, ² was punished with death; and after him others were executed in flocks; then finally they came to the case of Theodorus himself, as if to the dusty arena of an Olympic contest.
