And it was no equal return of favour that you made them, nor one free from disgrace. For you introduced them, as you say, when you were being injured; but you became co-operators with them in injuring others. And yet not to return equal favours is more disgraceful than to fail in those which, though justly due, will be returned in furtherance of injustice.
"You showed then plainly, that not even at that time was it for the sake of the Greeks that you alone did not Medize, but because the Athenians did not either, and because you wished to side with them, and against the rest.
And now you claim to derive assistance from the circumstances in which you acted well through the influence of others. That however is not reasonable; but as you chose the Athenians, stand the brunt of the struggle with them, and do not bring forward the league that was then made, as though you ought to be spared from regard to that.
For you deserted it, and in violation of it joined in enslaving the Aeginetans, and some others who had entered into it, rather than prevented their being enslaved; and that too not against your will, but while enjoying the same laws as you have to the present time, and without any one's compelling you, as they did us.
Besides, the last proposal made to you before you were blockaded, that you should remain unmolested on condition of your aiding neither side, you did not accept. Who, then, could be more justly hated by the Greeks than you, who assumed an honourable bearing for their injury? And the goodness which you say you once exhibited, you have now shown to be not your proper character; but what your nature always wished, has been truly proved against you; for you accompanied the Athenians when they were walking in the path of injustice.
With regard then to our involuntary Medizing, and your voluntary Atticizing, such are the proofs we have to offer.
"As for the last injuries which you say that you received, namely, that we came against your city in time of peace and at a holy time of the month, we are of opinion that neither in this point did we act more wrongly than you.
If, indeed, we came against your city by our own design, and fought, and ravaged the land as enemies, we are guilty. But if men who were the first among you, both in property and family, wishing to stop you from your foreign connexion, and restore you to your hereditary principles common to all the Boeotians, voluntarily called us to their aid, how are we guilty?
