Schütz, the late German editor of Cicero, has subscribed to the opinion of Wolf, and has published the speech for Marcellus, along with the other four doubtful harangues at the end of the genuine orations.
But supposing that these five contested speeches are spurious, a sufficient number of genuine orations remain to enable us to distinguish the character of Cicero's eloquence. Ambitious from his youth of the honours attending a fine speaker, he early travelled to Greece, where he accumulated all the stores of knowledge and rules of art, which could be gathered from the rhetoricians, historians, and philosophers, of that intellectual land. While he thus extracted and imbibed the copiousness of Plato, the sweetness of Isocrates, and force of Demosthenes, he, at the same time, imbued his mind with a thorough knowledge of the laws, constitution, antiquities, and literature, of his native country. Nor did he less study the peculiar temper, the jealousies, and enmities of the Roman people, both as a nation and as individuals, without a knowledge of which, his eloquence would have been unavailing in the Forum or Comitia, where so much was decided by favouritism and cabal. By these means he ruled the passions and deliberations of his countrymen with almost resistless sway--upheld the power of the Senate--stayed the progress of tyranny--drove the audacious Catiline from Rome--directed the feelings of the state in favour of Pompey--shook the strong mind of Cæsar--and kindled a flame by which Antony had been nearly consumed. But the main secret of his success lay in the warmth and intensity of his feelings. His heart swelled with patriotism, and was dilated with the most magnificent conceptions of the glory of Rome. Though it throbbed with the fondest anticipations of posthumous fame, the momentary acclaim of a multitude was a chord to which it daily and most readily vibrated; while, at the same time, his high conceptions of oratory counteracted the bad effect which this exuberant vanity might otherwise have produced. Thus, when two speakers were employed in the same cause, though Cicero was the junior, to him was assigned the peroration, in which he surpassed all his contemporaries; and he obtained this pre-eminence not so much on account of his superior genius or knowledge of law, as because he was more moved and affected himself, without which he would never have moved or affected his judges.
