What can be more fatal to any emotional appeal than that the speaker should, when the situation calls for grief, anger, indignation or pity, not merely avoid the expression of those emotions which require to be kindled in the judge, but outrage the dignity of the courts with noises such as are dear to the Lycians and Carians? For Cicero [*](Or. xviii. 57. ) has told us that the rhetoricians of Lycia and Caria come near to singing in their perorations. But, as a matter of tact, we have somewhat overstepped the limits imposed by the more restrained style of singing.
I ask you, does anyone sing, I will not say when his theme is murder, sacrilege or parricide, but at any rate when he deals with figures or accounts, or, to cut a long story short, when he is pleading in any kind of lawsuit whatever? And if such a form of intonation is to be permitted at all, there is really no reason why the modulations of the voice should not be accompanied by harps and flutes, or even by cymbals, which would be more appropriate to the revolting exhibitions of which I am speaking.
