Such was the answer made by Periklês in defence of his policy against the opposition headed by Thucydidês. And as far as we can make out the ground taken by both parties, the answer was perfectly satisfactory. For when we look at the very large sum which Periklês continually kept in reserve in the treasury, no one could reasonably complain that his expenditure for ornamental purposes was carried so far as to encroach upon the exigences of defence. What Thucydidês and his partisans appear to have urged, was, that this common fund should still continue to be spent in aggressive warfare against the Persian king, in Egypt and elsewhere,—conformably to the projects pursued by Kimon during his life.[31] But Periklês was right in contending that such outlay would have been simply wasteful; of no use either to Athens or her allies, though risking all the chances of distant defeat, such as had been experienced a few years before in Egypt. The Persian force was already kept away, both from the waters of the Ægean and the coast of Asia, either by the stipulations of the treaty of Kallias, or—if that treaty be supposed apocryphal—by a conduct practically the same as those stipulations would have enforced. The _allies_, indeed, might have had some ground of complaint against Periklês, either for not reducing the amount of tribute required from them, seeing that it was more than sufficient for the legitimate purposes of the confederacy, or for not having collected their positive sentiment as to the disposal of it. But we do not find that this was the argument adopted by Thucydidês and his party, nor was it calculated to find favor either with aristocrats or democrats, in the Athenian assembly.
