The extract last given[363] shows with what adroitness he introduces dialogues, in which he questions or answers an imaginary critic. This is a device frequently employed with considerable effect. The following shows a rather different type:

‘If Philip captures Olynthus, who will prevent him from marching on us? The Thebans? It is an unpleasant thing to say, but they will eagerly join him in the invasion. Or the Phocians?—when they cannot even protect their own land, unless you help them. Can you think of any one else?—“My dear fellow, he won’t want to attack us.” It would indeed be the greatest surprise in the world if he did not do it when he got the chance; since even now he is fool enough to declare his intentions.’[364]

Narrative, too, can take the place of argument; a recital of Philip’s misdeeds during the last few years may do far more to convince the Athenians of the necessity for action than any argument about the case of a particular ally who chances to be threatened at the moment.[365]

Demosthenes’ knowledge of history was deep and broad. The superiority of his attainments to those of Aeschines is shown in the more philosophic use which he makes of his appeals to precedent; his examples are apposite and not far-fetched; he can illuminate the present not only by references to ancient facts, but by a keen insight into the spirit which animated the men of old times.[366]

The examples already quoted of rhetorical dialogue with imaginary opponents will have given some idea of his use of a sarcastic tone. Sarcasm thinly concealed may at times run through a passage of considerable length, as in the anecdote which follows. We may note in passing that he is usually sparing in the use of anecdote, which is never employed without good reason. Here it may be excused by the fact that it figures as an historical precedent of a procedure which he ironically recommends to his contemporaries.

Inveighing against the reckless procedure of the Athenian politicians, who propose laws for their own benefit almost every month,[367] he recounts the customs of the Locrians, and, with an assumption of seriousness, implies a wish that similar restrictions could be imposed at Athens:

‘I should like to tell you, Gentlemen, how legislation is conducted among the Locrians. It will do you no harm to have an example before you, especially the example of a well-governed State. There men are so convinced that they ought to keep to the established laws and cherish their traditions, and not legislate to suit their fancy, or to help a criminal to escape, that any man who wishes to pass a new law must have a rope round his neck while he proposes it. If they think that the law is a good and useful one, the proposer lives and goes on his way; if not, they pull the rope and there is an end of him. For they cannot bear to pass new laws, but they rigorously observe the old ones. We are told that only one new law has been enacted in very many years. Whereas there was a law that if a man knocked out another man’s eye, he should submit to having his own knocked out in return, and no monetary compensation was provided, a certain man threatened his enemy, who had already lost an eye, to knock out the one eye he had left. The one-eyed man, alarmed by the threat, and thinking that life would not be worth living if it were put into execution, ventured to propose a law that if a man knocks out the eye of a man who has only one, he shall submit to having both his own knocked out in return, so that both may suffer alike. We are told that this is the only law which the Locrians have passed in upwards of two hundred years.’[368]

This, however, occurs in a speech before the law-courts; it is excellent in its place, but would have been unsuitable to the more dignified and solemn style in which he addresses the assembly. Equally unsuitable to his public harangues would be anything like the virulent satire which he admits into the de Corona, the vulgar personalities of abuse and gross caricatures of Aeschines and his antecedents.[369] For these the only excuse is that, though meant maliciously, they are so exaggerated as to be quite incredible. They may be compared to Aristophanes’ satire of Cleon in the Knights, which was coarse enough, but cannot have done Cleon any serious harm. Demosthenes indeed becomes truly Aristophanic when he talks about Aeschines’ acting:

‘When in the course of time you were relieved of these duties, having yourself committed all the offences of which you accuse others, I vow that your subsequent life did not fall short of your earlier promise. You engaged yourself to the players Simylus and Socrates, the “Bellowers,” as they were called, to play minor parts, and gathered a harvest of figs, grapes, and olives, like a fruiterer getting his stock from other people’s orchards; and you made more from this source than from your plays, which you played in dead earnest at the risk of your lives; for there was a truceless and merciless war between you and the spectators, from whom you received so many wounds that you naturally mock at the cowardice of those who have never had that great experience.’[370]
