In my judgement they could not have done you a more grievous injury. To turn their treaty of peace with a mortal man, a mere potentate of occasion, into a covenant of immortal ignominy for the commonwealth; to strip their city of all she had, even of the largess of her good fortune; in the veriest extravagance of malice to heap injuries not only on the Athenians of today but upon all who shall hereafter be Athenians,—is not that an appalling iniquity?
Never would you have consented to add to the treaty by afterthought the words and to his posterity, but for your confidence in the promises alleged by Aeschines. In those promises the Phocians confided,—and perished! They surrendered themselves to Philip; of their own accord they put their cities at his mercy; and their treatment has exactly contradicted all the assurances of Aeschines.
