Wherein, then, lies the force of an oratorical image? Doubtless in
adding energy and passion in a hundred different ways to a speech; but
especially in this, that when it is mingled with the practical,
argumentative parts of an oration, it does not merely convince the
hearer, but enthralls him. Such is the effect of those words of
Demosthenes:[16] “Supposing, now, at this moment a cry of alarm were
heard outside the assize courts, and the news came that the prison was
broken open and the prisoners escaped, is there any man here who is such
a trifler that he would not run to the rescue at the top of his speed?
But suppose some one came forward with the information that they had
been set at liberty by the defendant, what then? Why, he would be
lynched on the spot!”

Compare also the way in which Hyperides excused himself, when he was
proceeded against for bringing in a bill to liberate the slaves after
Chaeronea. “This measure,” he said, “was not drawn up by any orator, but
by the battle of Chaeronea.” This striking image, being thrown in by the
speaker in the midst of his proofs, enables him by one bold stroke to
carry all mere logical objection before him.
