"Catilina in particular was one of the most nefarious men in that nefarious age. His villanies belong to the criminal records, not to history; but his very outward appearance - the pale countenance, the wild glance, the gait by turns sluggish and hurried - betrayed his dismal past. He possessed in a high degree the qualities which are required in the leader of such a band - the faculty of enjoying all pleasures and of bearing all privations, courage, military talent, knowledge of men, the energy of a felon, and that horrible mastery of vice which knows how to bring the weak to fall, and how to train the fallen to crime."
