This congress met in the spring of 424 B.C., when Syracuse, the most powerful city in Sicily, took the lead in urging the common interest which all had in the conclusion of peace. The Syracusan Hermokratês, chief adviser of this policy in his native city, now appeared to vindicate and enforce it in the congress. He was a well-born, brave, and able man, clear-sighted in regard to the foreign interests of his country; but at the same time of pronounced oligarchical sentiments, mistrusted by the people, seemingly with good reason, in regard to their internal constitution. The speech which Thucydidês places in his mouth, on the present occasion, sets forth emphatically the necessity of keeping Sicily at all cost free from foreign intervention, and of settling at home all differences which might arise between the various Sicilian cities. Hermokratês impressed upon his hearers that the aggressive schemes of Athens, now the greatest power in Greece, were directed against all Sicily, and threatened all cities alike, Ionians not less than Dorians. If they enfeebled one another by internal quarrels, and then invited the Athenians as arbitrators, the result would be ruin and slavery to all. The Athenians were but too ready to encroach everywhere, even without invitation: they had now come, with a zeal outrunning all obligation, under pretence of aiding the Chalkidic cities who had never aided them, but in the real hope of achieving conquest for themselves. The Chalkidic cities must not rely upon their Ionic kindred for security against evil designs on the part of Athens: as Sicilians, they had a paramount interest in upholding the independence of the island. If possible, they ought to maintain undisturbed peace; but if that were impossible, it was essential at least to confine the war to Sicily, apart from any foreign intruders. Complaints should be exchanged, and injuries redressed, by all, in a spirit of mutual forbearance; of which Syracuse—the first city in the island, and best able to sustain the brunt of war—was prepared to set the example, without that foolish over-valuation of favorable chances so ruinous even to first-rate powers, and with full sense of the uncertainty of the future. Let them all feel that they were neighbors, inhabitants of the same island, and called by the common name of Sikeliots; and let them all with one accord repel the intrusion of aliens in their affairs, whether as open assailants or as treacherous mediators.[207] [207] See the speech of Hermokratês, Thucyd. iv, 59-64. One expression in this speech indicates that it was composed by Thucydidês many years after its proper date, subsequently to the great expedition of the Athenians against Syracuse in 415 B.C.; though I doubt not that Thucydidês collected the memoranda for it at the time.
