And now you expect to be rewarded for the virtuous conduct that was due to the inspiration of others! But that is unreasonable; as you chose the Athenians, continue to fight on their side. And do not keep reminding us of the alliance you made then, and claim that it ought to save you now.
For you have abandoned it and in violation of its principles have constantly aided, instead of trying to prevent, the enslavement of the Aeginetans[*](cf. cv., cviii.; 2.27.) and other members of the alliance; and that, too, not against your will, since you then enjoyed the laws under which you have lived till now and were not, like us, under compulsion by another.
Moreover, you refused to accept the last proposal we made you before Plataea was invested[*](cf. 2.72.1.)—to leave you unmolested if you would aid neither side. Who, then, would more justly be hated by all the Hellenes than you, who displayed your virtue in order to compass their injury? Furthermore, those noble qualities which, as you claim, you once displayed you have now made plain were not properly yours, but your natural longings have been put to the proof and shown in their reality;
for you have followed the Athenians when they walked in the way of iniquity. Such, then, is our affirmation regarding our unwilling medism and your willing atticism.
"As to your last charge of wrong-doing on our part—that we unlawfully attacked your city in time of peace and on a day of festival—we do not think that in this matter, either, we are more at fault than you.
