He put on armor, and was attended from his house by the noble citizens in a body; and a number of the young men went with him into the Plain. Here, designedly letting his tunic slip partly off from his shoulders, he showed his armor underneath, and discovered his danger to the spectators, who, being much moved at it, gathered around about him for his defence. At length, Catiline was by general suffrage again put by, and Silanus and Murena chosen consuls. Not long after this, Catiline's soldiers got together in a body in Etruria, and began to form themselves into companies, the day appointed for the design being near at hand. About midnight, some of the principal and most powerful citizens of Rome, Marcus, Crassus, Marcus Marcellus, and Scipio Metellus went to Cicero's house, where, knocking at the gate, and calling up the porter, they commanded him to awake Cicero, and tell him they were there. The business was this: Crassus's porter after supper had delivered to him letters brought by an unknown person. Some of them were directed to others, but one to Crassus, without a name; this only Crassus read, which informed him that there was a great slaughter intended by Catiline, and advised him to leave the city. The others he did not open, but went with them immediately to Cicero, being affrighted at the danger, and to free himself of the suspicion he lay under for his familiarity with Catiline. Cicero, considering the matter, summoned the senate at break of day. The letters he brought with him, and delivered them to those to whom they were directed, commanding them to read them publicly; they all alike contained an account of the conspiracy. And when Quintus Arrius, a man of praetorian dignity, recounted to them, how soldiers were collecting in companies in Etruria, and Manlius was stated to be in motion with a large force, hovering about those cities, in expectation of intelligence from Rome, the senate made a decree to place all in the hands of the consuls, who should undertake the conduct of everything, and do their best to save the state. This was not a common thing, but only done by the senate in cases of imminent danger.
