Hermocrates spoke to this effect; and after him, Euphemus, the Athenian ambassador, as follows:
"Though we are come hither for the purpose of renewing our former alliance, yet, as the Syracusan orator has attacked us on that head, we must also address you on the subject of our empire, to show that we enjoy it on just grounds.
The strongest proof, then, of this he himself has mentioned, in his assertion that the Ionians have ever been hostile to the Dorians. And such too is the case. For we, who are Ionians, considered, with regard to the Peloponnnesians. who are Dorians, and more numerous than ourselves, and living near us, in what way we might be least subject to them.
And after the Median invasion, having got a fleet, we released ourselves from the empire and supremacy of the Lacedaemonians; since they had no more right to command us than we them, except so far as they were at present more powerful. Thus having been ourselves appointed leaders of those who were before under the king, we so continue; considering that in this way we should least fall under the power of the Peloponnesians, by having a force with which to defend ourselves; and, to speak accurately, not having unjustly, either, reduced the Ionians and islanders to subjection, whom the Syracusans say that we have enslaved, though our kinsmen.
