Apollodorus Against Stephanus, Charged with False Testimony I (50-52)

For you have sworn to give a verdict, not in regard to matters upon which the defendant asks your decision, but in regard to those only which are raised by the prosecution. The cause of action must be made clear by the complaint of the prosecutor, and this in my case is a suit against this man for false testimony. Let him not, then, leave this and talk about matters regarding which I am not suing him; and do you, if he is so shameless, refuse to permit it.

I imagine that, having no just argument to advance on any point, he will have recourse to this defence also—that it is absurd for me, after having been worsted in the case of the special plea, to sue those who gave evidence of a will; and he will maintain that the jurymen in that trial were led to vote in favor of Phormio, by the evidence of those who testified to the release rather than by that of those who testified to the will. But, men of Athens, I think you all know that it is your habit to examine the facts no less closely than the pleas which men make regarding them; and these men, by giving false testimony against me regarding the facts themselves, weakened my arguments on the special plea.

However, besides this, it is absurd, when all have given false evidence, to demonstrate who did the greatest amount of harm, instead of making each one prove that he has himself testified to the truth. It is not by proving that another has done more outrageous things than himself that a witness is to be let off, but by showing that he has himself given testimony that is true.
