They, our kinsfolk, came against their mother country, that is to say against us, together with the Mede, and instead of having the courage to revolt and sacrifice their property as we did when we abandoned our city, chose to be slaves themselves, and to try to make us so.
We, therefore, deserve to rule because we placed the largest fleet and an unflinching patriotism at the service of the Hellenes, and because these, our subjects, did us mischief by their ready subservience to the Medes; and, desert apart, we seek to strengthen ourselves against the Peloponnesians.
We make no fine professions of having a right to rule because we overthrew the barbarian single-handed, or because we risked what we did risk for the freedom of the subjects in question any more than for that of all, and for our own: no one can be quarrelled with for providing for his proper safety. If we are now here in Sicily, it is equally in the interest of our security, with which we perceive that your interest also coincides.
