M. Tullius Cicero Pro P. Sulla 68

[68] But even if any one had had a doubt on that subject before, would he have thought (as you accuse him of having done) of descending, after the murder of your father, who was then consul, into the Campus on the first of January with the lictors? This suspicion, in fact you removed yourself, when you said that he had prepared an armed band and cherished violent designs against your father, in order to make Catiline consul. And if I grant you this, then you must grant to me that Sulla, when he was voting for Catiline, had no thoughts of recovering by violence his own consulship, which he had lost by a judicial decision. For his character is not one, O judges, which is at all liable to the imputation of such enormous, of such atrocious crimes.
