The following scene which occurred in the senate shows significantlyhow matters stood.  Immediately after the arrest of Lentulus and his comrades, a messenger despatched by the conspirators in the capital to Catilina was seized by the agents of the government, and, after having been assured of impunity, was induced to make a comprehensive confession in a full meeting of the senate.  But when he came to the critical portions of his confession and in particular named Crassus as having commissioned him, he was interrupted by the senators, and on the suggestion of Cicero it was resolved to cancel the whole statement without farther inquiry, but to imprison its author notwithstanding the amnesty assured to him, until such time as he should have not merely retracted the statement, but should have also confessed who had instigated him to give such false testimony!  Here it is abundantly clear, not merely that that man had a very accurate knowledge of the state of matters who, when summoned to make an attack upon Crassus, replied that he had no desire to provoke the bull of the herd, but also that the majority of the senate with Cicero at their head were agreed in not permitting the revelations to go beyond a certain limit.  The public was not so nice; the young men, who had taken up arms to ward off the incendiaries, were exasperated against no one so much as against Caesar, on the 5th of December, when he left the senate, they pointed their swords at his breast and even now he narrowly escaped with his life on the same spot where the fatal blow fell on him seventeen years afterwards; he did not again for a considerable time enter the senate-house.  Any one who impartially considers the course of the conspiracy will not be able to resist the suspicion that during all this time Catilina was backed by more powerful men, who—­relying on the want of a legally complete chain of evidence and on the lukewarmness and cowardice of the majority of the senate, which was but half-initiated and greedily caught at any pretext for inaction—­knew how to hinder any serious interference with the conspiracy on the part of the authorities, to procure free departure for the chief of the insurgents, and even so to manage the declaration of war and the sending of troops against the insurrection that it was almost equivalent to the sending of an auxiliary army.  While the course of the events themselves thus testifies that the threads of the Catilinarian plot reached far higher than Lentulus and Catilina, it deserves also to be noticed, that at a much later period, when Caesar had got to the head of the state, he was in the closest alliance with the only Catilinarian still surviving, Publius Sittius the leader of the Mauretanian free bands, and that he modified the law of debt quite in the sense that the proclamations of Manlius demanded.
