Moreover, the reputation of Kleon as a frequent and unmeasured accuser of others, may be explained partly by a passage of his enemy Aristophanês: a passage the more deserving of confidence as a just representation of fact, since it appears in a comedy (the “Frogs”) represented (405 B.C.) fifteen years after the death of Kleon, and five years after that of Hyperbolus, when the poet had less motive for misrepresentations against either. In the “Frogs,” the scene is laid in Hades, whither the god Dionysus goes, in the attire of Hêraklês and along with his slave Xanthias, for the purpose of bringing up again to earth the deceased poet Euripidês. Among the incidents, Xanthias, in the attire which his master had worn, is represented as acting with violence and insult towards two hostesses of eating-houses; consuming their substance, robbing them, refusing to pay when called upon, and even threatening their lives with a drawn sword. Upon which the women, having no other redress left, announce their resolution of calling, the one upon her protector Kleon, the other on Hyperbolus, for the purpose of bringing the offender to justice before the dikastery.[760] This passage shows us, if inferences on comic evidence are to be held as admissible, that Kleon and Hyperbolus became involved in accusations partly by helping poor persons who had been wronged to obtain justice before the dikastery. A rich man who had suffered injury might apply to Antipho or some other rhetor for paid advice and aid as to the conduct of his complaint; but a poor man or woman would think themselves happy to obtain the gratuitous suggestion, and sometimes the auxiliary speech, of Kleon or Hyperbolus; who would thus extend their own popularity, by means very similar to those practised by the leading men in Rome.[761]

But besides lending aid to others, doubtless Kleon was often also a prosecutor, in his own name, of official delinquents, real or alleged. That some one should undertake this duty was indispensable for the protection of the city; otherwise, the responsibility to which official persons were subjected after their term of office would have been merely nominal: and we have proof enough that the general public morality of these official persons, acting individually, was by no means high. But the duty was at the same time one which most persons would and did shun. The prosecutor, while obnoxious to general dislike, gained nothing even by the most complete success; and if he failed so much as not to procure a minority of votes among the dikasts, equal to one-fifth of the numbers present, he was condemned to pay a fine of one thousand drachms. What was still more serious, he drew upon himself a formidable mass of private hatred, from the friends, partisans, and the political club, of the accused party, extremely menacing to his own future security and comfort, in a community like Athens. There was therefore little motive to accept, and great motive to decline, the task of prosecuting on public grounds. A prudent politician at Athens would undertake it occasionally, and against special rivals, but he would carefully guard himself against the reputation of doing it frequently or by inclination, and the orators constantly do so guard themselves in those speeches which yet remain.

It is this reputation which Thucydidês fastens upon Kleon, and which, like Cato the censor at Rome, he probably merited; from native acrimony of temper, from a powerful talent for invective and from his position, both inferior and hostile to the Athenian knights, or aristocracy, who overshadowed him by their family importance. But in what proportion of cases his accusations were just or calumnious, the real question upon which a candid judgment turns, we have no means of deciding, either in his case or that of Cato. “To lash the wicked (observes Aristophanês himself[762]) is not only no blame, but is even a matter of honor to the good.” It has not been common to allow to Kleon the benefit of this observation, though he is much more entitled to it than Aristophanês. For the attacks of a poetical libeller admit neither of defence nor retaliation; whereas a prosecutor before the dikastery found his opponent prepared to reply or even to retort, and was obliged to specify his charge, as well as to furnish proof of it; so that there was a fair chance for the innocent man not to be confounded with the guilty.

The quarrel of Kleon with Aristophanês is said to have arisen out of an accusation which he brought against that poet[763] in the Senate of Five Hundred, on the subject of his second comedy, the “Babylonians,” exhibited B.C. 426, at the festival of the urban Dionysia in the month of March. At that season many strangers were present at Athens, and especially many visitors and deputies from the subject-allies, who were bringing their annual tribute: and as the “Babylonians,” (now lost), like so many other productions of Aristophanês, was full of slashing ridicule, not only against individual citizens but against the functionaries and institutions of the city,[764] Kleon instituted a complaint against it in the senate, as an exposure dangerous to the public security before strangers and allies. We have to recollect that Athens was then in the midst of an embarrassing war; that the fidelity of her subject-allies was much doubted; that Lesbos, the greatest of her allies, had been reconquered only in the preceding year, after a revolt both troublesome and perilous to the Athenians. Under such circumstances, Kleon had good reason for thinking that a political comedy of the Aristophanic vein and talent tended to degrade the city in the eyes of strangers, even granting that it was innocuous when confined to the citizens themselves. The poet complains[765] that Kleon summoned him before the senate, with terrible threats and calumny: but it does not appear that any penalty was inflicted. Nor, indeed, had the senate competence to find him guilty or punish him except to the extent of a small fine: they could only bring him to trial before the dikastery, which in this case plainly was not done. He himself, however, seems to have felt the justice of the warning: for we find that three out of his four next following plays, before the Peace of Nikias,—the Acharnians, the Knights, and the Wasps,—were represented at the Lenæan festival,[766] in the month of January, a season when no strangers nor allies were present. Kleon was doubtless much incensed with the play of the Knights, and seems to have annoyed the poet either by bringing an indictment against him for exercising freemen’s rights without being duly qualified, since none but citizens were allowed to appear and act in the dramatic exhibitions, or by some other means which are not clearly explained. Nor can we make out in what way the poet met him, though it appears that finding less public sympathy than he thought himself entitled to, he made an apology without intending to be bound by it.[767] Certain it is, that his remaining plays subsequent to the Knights, though containing some few bitter jests against Kleon, manifest no second deliberate set against him.

The battle of Amphipolis removed at once the two most pronounced individual opponents of peace, Kleon and Brasidas. Athens too was more than ever discouraged and averse to prolonged fighting; for the number of hoplites slain at Amphipolis doubtless filled the city with mourning, besides the unparalleled disgrace now tarnishing Athenian soldiership. The peace-party under the auspices of Nikias and Lachês, relieved at once from the internal opposition of Kleon, as well as from the foreign enterprise of Brasidas, were enabled to resume their negotiations with Sparta in a spirit promising success. King Pleistoanax, and the Spartan ephors of the year, were on their side equally bent on terminating the war, and the deputies of all the allies were convoked at Sparta for discussion with the envoys of Athens. Such discussion was continued during the whole autumn and winter after the battle of Amphipolis, without any actual hostilities on either side. At first, the pretensions advanced were found very conflicting; but at length, after several debates, it was agreed to treat upon the basis of each party surrendering what had been acquired by war. The Athenians insisted at first on the restoration of Platæa; but the Thebans replied that Platæa was theirs neither by force nor by treason, but by voluntary capitulation and surrender of the inhabitants. This distinction seems to our ideas somewhat remarkable, since the capitulation of a besieged town is not less the result of force than capture by storm. But it was adopted in the present treaty; and under it the Athenians, while foregoing their demand of Platæa, were enabled to retain Nisæa, which they had acquired from the Megarians, and Anaktorium and Sollium,[768] which they had taken from Corinth. To insure accommodating temper on the part of Athens, the Spartans held out the threat of invading Attica in the spring, and of establishing a permanent fortification in the territory: and they even sent round proclamation to their allies, enjoining all the details requisite for this step. Since Attica had now been exempt from invasion for three years, the Athenians were probably not insensible to this threat of renewal under a permanent form.

At the beginning of spring, about the end of March, 421 B.C., shortly after the urban Dionysia at Athens, the important treaty was concluded for the term of fifty years. The following were its principal conditions:—

1. All shall have full liberty to visit all the public temples of Greece, for purposes of private sacrifice, consultation of oracle, or public sacred mission. Every man shall be undisturbed both in going and coming. [The value of this article will be felt, when we recollect that the Athenians and their allies had been unable to visit the Olympic or Pythian festival since the beginning of the war.]

2. The Delphians shall enjoy full autonomy and mastery of their temple and their territory. [This article was intended to exclude the ancient claim of the Phocian confederacy to the management of the temple; a claim which the Athenians had once supported, before the thirty years’ truce: but they had now little interest in the matter, since the Phocians were in the ranks of their enemies.]

3. There shall be peace for fifty years, between Athens and Sparta with their respective allies, with abstinence from mischief, either overt or fraudulent, by land as well as by sea.

4. Neither party shall invade for purposes of mischief the territory of the other, not by any artifice or under any pretence.
