Theophrastus adds that the exordium may be drawn from the speech of one's opponent, as that of the pro Ctesiphonte of Demosthenes appears to be, where he asks that he may be allowed to speak as he pleases and not to be restricted to the form laid down by the accuser in his speech.
Confidence often labours under the disadvantage of being regarded as arrogance. But there are certain tricks for acquiring good-will, which though almost universal, are by no means to be neglected, if only to prevent their being first employed against ourselves. I refer to rhetorical expressions of wishing, detestation, entreaty, or anxiety. For it keeps the judge's attention on the alert, if he is led to think the case novel, important, scandalous, or likely to set a precedent, still more if he is excited by concern for himself or the common weal, when
We shall also find it a useful device for wakening the attention of our audience to create the impression that we shall not keep them long and intend to stick closely to the point. The mere fact of such attention undoubtedly makes the judge ready to receive instruction from us, but we shall contribute still more to this effect if we give a brief and lucid summary of the case which he has to try; in so doing we shall be following the method adopted by Homer and Virgil at the beginning of their poems.
For as regards the length of the exordium, it should propound rather than expound, and should not describe how each thing occurred, but simply indicate the points on which the orator proposes to speak. I do not think a better example of this can be found than the exordium to the pro Cluentio of Cicero.
I have noted, judges, that the speech for the prosecution was divided into two parts: of these, the first seemed to rest and in the main to rely on the odium, now inveterate, arising from the trial before Junius, while the other appeared to touch, merely as a matter of form, and with a certain timidity and diffidence, on the question of the charge of poisoning, though it is to try this point that the present court has been constituted in accordance with the law.All this, however, is easier for the defender than the prosecutor, since the latter has merely to remind the judge, while the former has to instruct him.
