This first argument, drawn both from the rules of civil rights, and from the customs prevailing with respect to such security, is a most important and powerful one, which I would press at greater length, if I had not other more undeniable and manifest proofs in the cause. And that you may not say I have promised this on insufficient grounds, I will call you—you, I say, Fannius—from your seat as a witness against yourself.—What is your charge? That Roscius settled with Flavius on behalf of the partnership.—When? Four years ago.—What is my defence? That Roscius settled with Flavius for his share in the property. You yourself, three years ago, made a new engagement with Roscius.—What? Recite that stipulation plainly.—Attend, I beg you, O Piso—I am compelling Fannius against his will, and though he is shuffling off in every direction, to give evidence against himself. For what are the words of this new agreement? “Whatever I receive from Flavius, I undertake to pay one half of to Roscius.” These are your words, O Fannius.
