On beginning to apply himself more resolutely to public business, he remarked it as unreasonable that artificers, using vessels and instruments inanimate, should know the name, place, and use of every one of them, and yet the statesman, whose instruments for carrying out public measures are men, should be negligent and careless in the knowledge of persons. And so he not only acquainted himself with the names, but also knew the very place where every one of the more eminent citizens dwelt, what lands he possessed, his friends and his neighbors, and when he traveled on any road in Italy, he could readily name and show the estates and seats of his acquaintances. Having a small competency for his own expenses, it was much wondered at that he took neither fees nor gifts from his clients, and especially, that he did not do so when he undertook the prosecution of Verres. This Verres, who had been praetor of Sicily, and stood charged by the Sicilians with many evil practices during his government there, Cicero succeeded in getting condemned, not by speaking, but, as it were, by holding his tongue. For the praetors, favoring Verres, had deferred the trial by several adjournments to the last day, in which it was evident there could not be sufficient time for the advocates to be heard, and the cause brought to an issue. Cicero, therefore, came forward, and said there was no need of speeches; and after producing and examining witnesses, he required the judges to proceed to sentence. Many witty sayings are on record, as having been used by Cicero on the occasion. When a man named Caecilius, one of the freed slaves, who was said to be given to Jewish practices, would have put by the Sicilians, and undertaken the prosecution of Verres himself, Cicero asked, "What has a Jew to do with swine?" verres being the Roman word for a boar. And when Verres began to reproach Cicero with effeminate living, "You ought," replied he, "to use this language at home, to your sons;" Verres having a son who had fallen into disgraceful courses. Hortensius, the orator, not daring directly to undertake the defence of Verres, was yet persuaded to appear for him at the laying on of the fine, and received an ivory sphinx for his reward; and when Cicero, in some passage of his speech, obliquely reflected on him, and Hortensius told him he was not skilful in solving riddles, "No," said Cicero, "and yet you have the Sphinx in your house!"

Verres was thus convicted; though Cicero, who set the fine at seventy-five myriads, lay under the suspicion of being corrupted by bribery to lessen the sum. But the Sicilians, in testimony of their gratitude, came and brought him all sorts of presents from the island, when he was aedile; of which he made no private profit himself, but used their generosity only to reduce the public price of provisions.

He had a very pleasant seat at Arpi, he had also a farm near Naples, and another near Pompeii, but none were of any great value. The portion of his wife, Terentia, amounted to ten myriads, and he had a bequest valued at nine myriads of denarii: upon these he lived in a liberal but temperate style, with the learned Greeks and Romans that were his familiars. He rarely, if at any time, sat down to meat till sunset, and that not so much on account of business as for his health and the weakness of his stomach. He was otherwise in the care of his body nice and delicate, appointing himself, for example, a set number of walks and rubbings. And after this manner managing the habit of his body, he brought it in time to be healthful, and capable of supporting many great fatigues and trials. His father's house he made over to his brother, living himself near the Palatine Hill, that he might not give the trouble of long journeys to those that made suit to him. And, indeed, there were not fewer daily appearing at his door, to do their court to him, than there were that came to Crassus for his riches, or to Pompey for his power among the soldiers, these being at that time the two men of the greatest repute and influence in Rome. Nay, even Pompey himself used to pay court to Cicero, and Cicero's public actions did much to establish Pompey's authority and reputation in the state.

Numerous distinguished competitors stood with him for the praetor's office; but he was chosen before them all, and managed the decision of causes with justice and integrity. It is related that Licinius Macer, a man himself of great power in the city, and supported also by the assistance of Crassus, was accused before him of extortion, and that, in confidence on his own interest and the diligence of his friends, whilst the judges were debating about the sentence, he went to his house, where hastily trimming his hair and putting on a clean gown, as already acquitted, he was setting off again to go to the Forum; but at his hall door meeting Crassus, who told him that he was condemned by all the votes, he went in again, threw himself upon his bed, and died immediately. This verdict was considered very creditable to Cicero, as showing his careful management of the courts of justice.

Yet he was preferred to the consulship no less by the nobles than the common people for the good of the city; and both parties jointly assisted his promotion, for the following reasons. The change of government made by Sylla, which at first seemed a senseless one, by time and usage had now come to be considered by the people no unsatisfactory settlement. But there were some that endeavored to alter and subvert the whole present state of affairs, not from any good motives, but for their own private gain; and Pompey being at this time employed in the wars with the kings of Pontus and Armenia, there was no sufficient force at Rome to suppress any attempts at a revolution. These people had for their head a man of bold, daring, and restless character, Lucius Catiline, who was accused, besides other great offences, of killing his own brother; and fearing to be prosecuted at law, he persuaded Sylla to set his brother down, as though he were yet alive, amongst those that were to be put to death by proscription. This man the profligate citizens choosing for their captain, gave faith to one another, amongst other pledges, by sacrificing a man and eating of his flesh; and a great part of the young men of the city were corrupted by him, he providing for every one pleasures and drink, and profusely supplying the expense of their debauches. Etruria, moreover, had all been excited to revolt, as well as a great part of Gaul within the Alps. But Rome itself was in the most dangerous inclination to change on account of the unequal distribution of wealth and property, those of highest rank and greatest spirit having impoverished themselves by shows, entertainments, running for office, and sumptuous buildings, and the riches of the city had thus fallen into the hands of mean and low-born persons. So that it required but a slight impetus to set all in motion, it being in the power of any daring man to overturn a sickly commonwealth.

Catiline, however, being desirous of procuring a strong position to carry out his designs, stood for the consulship, and had great hopes of success, thinking he should be appointed, with Caius Antonius as his colleague, who was a man fit to lead neither in a good cause nor in a bad one, but might be a valuable accession to another's power. The greater part of the good and honest citizens apprehending these things, put Cicero upon standing for the consulship; whom the people readily receiving, Catiline was put by, so that he and Caius Antonius were chosen, although amongst the competitors he was the only man descended from the father of the equestrian, and not of the senatorial, order.

Though the designs of Catiline were not yet publicly known, yet considerable trouble immediately followed 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 entreated the people; 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 conquests, of judging and banishing whom they pleased, of planting colonies, of taking money out of the treasury, and of levying and paying what soldiers should be though needful. And several of the nobility favored 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, endeavoring in the first place to provide a remedy against this danger, procured a decree assigning to Antonius the province of Macedonia, he himself declining that of Gaul, which was offered to him. And this piece of favor so completely won over Antonius, that he was ready to second, like a hired player, whatever Cicero said for the good of the country. And now, having made his colleague tame and tractable, he could with greater courage attack the conspirators. 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.

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 presented. An incident occurred in the theatre, during his consulship, which showed what his speaking could do. Formerly the knights of Rome were mingled in the theatre with the common people, and took their places amongst them just as it happened; but when Marcus Otho became praetor he distinguished them from the other citizens, and appointed them special seats, which they still enjoy as their 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 as to who should give him the greatest demonstrations of honor and respect.

The conspirators with Catiline, at first cowed and disheartened, began presently to take courage again. And assembling together, they exhorted one another boldly to undertake the design before Pompey's return. 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 among 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 aspired for the consulship, having resolved to kill Cicero in a tumult at the elections. 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 to convict 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 one 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 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.
