Cicero

Now Cicero, as it would seem, was not only without courage under arms, but also felt fear when he began to speak, and in many trials he hardly ceased quivering and trembling after his eloquence had become high and sustained. When he was to plead for Licinius Murena in a case brought against him by Cato, and was ambitious to surpass Hortensius, whom had made a successful plea, he took no rest at all during the night before, so that his lack of sleep and his great anxiety did him harm, and he was thought inferior to himself in his plea.

And so at this time, when he came out of his litter to plead Milo’s cause and saw Pompey stationed on the heights as in a camp, and arms flashing all around the forum, he was confounded and could scarcely begin his speech, for his body quivered and his voice faltered; whereas Milo showed the good courage of a brave man at the trial and had not deigned to let his hair go untrimmed or to change his attire to a dark one; and this seems most of all to have contributed to his condemnation. However, Cicero’s behaviour led men to think him devoted to his friends rather than cowardly.
