In Catilinam

In the meantime, about the end of the third watch, when the ambassadors of the Allobroges, with a great retinue and Vulturcius with them, began to come upon the Mulvian bridge, an attack is made upon them; swords are drawn both by them and by our people; the matter was understood by the praetors alone, but was unknown to the rest. Then, by the intervention of Pomtinus and Flaccus, the fight which had begun was put an end to; all the letters which were in the hands of the whole company are delivered to the praetors with time seals unbroken; the men themselves are arrested and brought to me at daybreak. And I immediately summoned that most worthless contriver of all this wickedness, Gabinius, as yet suspecting nothing; after him, P. Statilius is sent for, and after him Cethegus; but Lentulus was a long time in coming,—I suppose, because, contrary to his custom, he had been up a long time the night before, writing letters.

But when those most noble and excellent men of the whole city, who, hearing of the matter, came in crowds to me in the morning, thought it best for me to open the letters before I related the matter to the senate, lest, if nothing were found in them, so great a disturbance might seem to have been caused to the state for nothing, I said I would never so act as shrink from referring matter of public danger to the public council. In truth if, O Romans, these things which had been reported to me had not been found in them, yet I did not think I ought, in such a crisis of the republic, to be afraid of the imputation of over-diligence.
