of character and incapacity of decided or energetic effort. When he discovered that he had been out-manœuvred by the Lacedæmonian diplomacy, and had fatally misadvised his countrymen into making important cessions on the faith of equivalents to come, we might have expected to find him spurred on by indignant repentance for this mistake, and putting forth his own strongest efforts, as well as those of his country, in order to recover those portions of her empire which the peace had promised, but did not restore. Instead of which he exhibits no effective movement, while Alkibiadês begins to display the defects of his political character, yet more dangerous than those of Nikias, the passion for showy, precarious, boundless, and even perilous novelties. It is only in the year 417 B.C., after the defeat of Mantineia had put an end to the political speculations of Alkibiadês in the interior of Peloponnesus, that Nikias projects an expedition against Amphipolis; and even then it is projected only contingent upon the aid of Perdikkas, a prince of notorious perfidy. It was not by any half-exertions of force that the place could be regained, as the defeat of Kleon had sufficiently proved. We obtain from these proceedings a fair measure of the foreign politics of Athens at this time, during what is called the Peace of Nikias, preparing us for that melancholy catastrophe which will be developed in the coming chapters, where she is brought near to ruin by the defects of Nikias and Alkibiadês combined for, by singular misfortune, she does not reap the benefit of the good qualities of either.
