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

[28] Indeed, if in the case of Gaius Rabirius because he ran to the call for arms, Titus Labienus thought that a cross must be fixed in the Campus Martius, just what punishment will be devised for that man who summoned Rabirius? And if the promise of protective custody was given to Saturninus, as you have repeatedly claimed, Gaius Rabirius did not give it, but Gaius Marius gave it, and the same man violated it if he did not abide by its protection. What protective custody, Labienus, could be given, how could it be given, without a decree of the senate? [Are you] such a stranger to this city, so ignorant of our ways and customs that you do not know the answer, that you appear to be sojourning in a foreign city instead of conducting public office in your own?
