M. Tullius Cicero, Speech before Roman Citizens on Behalf of Gaius Rabirius, Defendant Against the Charge of Treason
William Blake Tyrrell, Ed.

[25] And so I marvel where you, Labienus, discovered this death mask you have in your possession. After Sextus Titius was condemned, no one was found who dared to possess one. But if you had heard about this or if you were old enough to know, surely you never would have brought to the Rostra and into a public meeting that death mask of yours which, when placed in his home, brought the plague of exile down upon Sextus Titius. Nor would you have driven your boat onto those rocks against which you saw Sextus Titius' ship dashed all to pieces and upon which you saw the shipwreck of all Gaius Decianus' fortunes.

But in all these matters, you are tripped up by your lack of foresight. You have undertaken a case older than your memory, a case which was dead before your were born. And had you been old enough, you of all people surely would have been implicated in the very case you are now hauling into court.
