The conspiracy, conducted by the adventurous spirit of its chief, had acquired considerable development. Senators, knights, young patricians, a great number of the notable citizens of the allied towns, partook in it. Cicero, informed of these designs, assembles the Senate in the Temple of Concord, and communicates to it the information he had received: he informs it that, on the 5th of the calends of November, a rising was to take place in Etruria; that on the morrow a riot would break out in Rome; that the lives of the consuls were threatened; that, lastly, everywhere stores of warlike arms and attempts to enlist the gladiators indicated the most alarming preparations. Catiline, questioned by the consul, exclaims, that the tyranny of some men, their avarice, their inhumanity, are the true causes of the uneasiness which torments the Republic; then, repelling with scorn the projects of revolt which they imputed to him, he concludes with this threatening figure of speech: “The Roman people is a robust body, but without head: I shall be that head.”[956] He departed with these words, leaving the Senate undecided and trembling. The assembly, meanwhile, passed the usual decree, enjoining the consuls to watch _that the Republic received no injury_.
The election of consuls for the following year, till then deferred, took place on the 21st of October, 691, and Silanus having been nominated with Murena, Catiline was a third time rejected. He then dispatched to different parts of Italy his agents, and among others, C. Mallius into Etruria, Septimius to the Picenum, and C. Julius into Apulia, to organise the revolt.[957] At the mouth of the Tiber, a division of the fleet, previously employed against the pirates, was ready to second his projects.[958] At Rome even the assassination of Cicero was boldly attempted.
The Senate was convened again on the 8th of November. Catiline dared to attend, and take his seat in the midst of his colleagues. Cicero, in a speech which has become celebrated, apostrophised him in terms of the strongest indignation, and by a crushing denunciation forced him to retire.[959] Catiline, accompanied by three hundred of his adherents, left the capital next morning to join Mallius.[960] During the following days, alarming news arriving from all parts threw Rome into the utmost anxiety. Stupor reigned there. To the animation of fêtes and pleasures had, all of a sudden, succeeded a gloomy silence. Troops were raised; armed outposts were placed at various points; Q. Marcius Rex is dispatched to Fæsulæ (_Fiesole_); Q. Metellus Creticus into Apulia; Pomponius Rufus to Capua; Q. Metellus Celer into the Picenum; and, lastly, the consul, C. Antonius, led an army into Etruria. Cicero had detached the latter from the conspiracy by giving him the lucrative government of Macedonia.[961] He accepted in exchange that of Gaul, which he also subsequently renounced, not wishing, after his consulship, to quit the city and depart as proconsul. The principal conspirators, at the head of whom were the prætor Lentulus and Cethegus, remained at Rome. They continued energetically the preparations for the insurrection, and entered into communication with the envoys of the Allobroges. Cicero, secretly informed by his spies, among others by Curius, watched their doings, and, when he had indisputable proofs, caused them to be arrested, convoked the Senate, and exposed the plan of the conspiracy.
