Though the designs of Catiline were not yet publicly known, yet considerable preliminary troubles immediately followed upon Cicero's entrance upon the consulship. For, on the one side, those who were disqualified by the laws of Sylla from holding any public offices, being neither inconsiderable in power nor in number, came forward as candidates and caressed the people for them; speaking many things truly and justly against the tyranny of Sylla, only that they disturbed the government at an improper and unseasonable time; on the other hand, the tribunes of the people proposed laws to the same purpose, constituting a commission of ten persons, with unlimited powers, in whom as supreme governors should be vested the right of selling the public lands of all Italy and Syria and Pompey's new conquest, of judging and banishing whom they pleased, of planting colonies, of taking moneys out of the treasury, and of levying and paying what soldiers should be thought needful. And several of the nobility favoured this law, but especially Caius Antonius, Cicero's colleague, in hopes of being one of the ten. But what gave the greatest fear to the nobles was, that he was thought privy to the conspiracy of Catiline, and not to dislike it because of his great debts.
Cicero, endeavouring in the first place to provide a remedy against this danger, procured a decree assigning to him the province of Macedonia, he himself declining that of Gaul, which was offered to him. And this piece of favour so completely won over Antonius, that he was ready to second and respond to, like a hired player, whatever Cicero said for the good of the country. And now, having made his colleague thus tame and tractable, he could with greater courage attack the conspirators. And, therefore, in the senate, making an oration against the law of the ten commissioners, he so confounded those who proposed it, that they had nothing to reply. And when they again endeavoured, and, having prepared things beforehand, had called the consuls before the assembly of the people, Cicero, fearing nothing, went first out, and commanded the senate to follow him, and not only succeeded in throwing out the law, but so entirely overpowered the tribunes by his oratory, that they abandoned all thought of their other projects.
For Cicero, it may be said, was the one man, above all others who made the Romans feel how great a charm eloquence lends to what is good, and how invincible justice is, if it be well spoken; and that it is necessary for him who would dexterously govern a commonwealth, in action, always to prefer that which is honest before that which is popular, and in speaking, to free the right and useful measure from everything that may occasion offence. An incident occurred in the theatre, during his consulship, which showed what his speaking could do. For whereas formerly the knights of Rome were mingled in the theatre with the common people, and took their places among them as it happened, Marcus Otho, when he was praetor, was the first who distinguished them from the other citizens and appointed them a proper seat, which they still enjoy as their special place in the theatre.
This the common people took as an indignity done to them, and, therefore, when Otho appeared in the theatre they hissed him; the knights, on the contrary, received him with loud clapping. The people repeated and increased their hissing; the knights continued their clapping. Upon this, turning upon one another, they broke out into insulting words, so that the theatre was in great disorder.
Cicero being informed of it, came himself to the theatre, and summoning the people into the temple of Bellona, he so effectually chid and chastised them for it, that again returning into the theatre they received Otho with loud applause, contending with the knights who should give him the greatest demonstrations of honour and respect.
The conspirators with Catiline, at first cowed and disheartened, began presently to take courage again. And assembling themselves together, they exhorted one another boldly to undertake the design before Pompey's return, who, as it was said, was now on his march with his forces for Rome. But the old soldiers of Sylla were Catiline's chief stimulus to action. They had been disbanded all about Italy, but the greatest number and the fiercest of them lay scattered among the cities of Etruria entertaining themselves with dreams of new plunder and rapine amongst the hoarded riches of Italy. These, having for their leader Manlius, who had served with distinction in the wars under Sylla, joined themselves to Catiline, and came to Rome to assist him with their suffrages at the election. For he again pretended to the consulship, having resolved to kill Cicero in a tumult at the elections. Also, the divine powers seemed to give intimation of the coming troubles, by earthquakes, thunderbolts, and strange appearances. Nor was human evidence wanting certain enough in itself, though not sufficient for the conviction of the noble and powerful Catiline. Therefore Cicero, deferring the day of election, summoned Catiline into the senate, and questioned him as to the charges made against him. Catiline, believing there were many in the senate desirous of change, and to give a specimen of himself to the conspirators present, returned an audacious answer, "What harm,"said he, "when I see two bodies, the one lean and consumptive with a head, the other great and strong without one, if I put a head to that body which wants one?" This covert representation of the senate and the people excited yet greater apprehensions in Cicero. He put on armour, 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.
