Institutio Oratoria

Laughter then will be derived either from the physical appearance of our opponent or from his character as revealed in his words and actions, or from external sources; for all forms of raillery come under one or other of these heads; if the raillery is serious, we style it as severe; if, on the other hand, it is of a lighter character, we regard it as humorous. These themes for jest may be pointed out to the eye or described in words or indicated by some mot.

The narration of a humorous story may often be used with clever effect and is a device eminently becoming to an orator. Good examples are the story told of Caepasius and Fabricius, which Cicero tells in the pro Cluentio, or the story told by Caelius of the dispute between Decimus Laelius and his colleague when they were both in a hurry to reach their province first. But in all such cases the whole narrative must possess elegance and charm, while the orator's own contribution to the story should be the most humorous element. Take for instance the way in which Cicero gives a special relish to the flight of Fabricius. [*](pro Cluent. xxi. 58. )
