Among those who paid that tribute were the Thessalians, Dolopes, Enienes, Perrhaebians, Locrians, Magnesians, Melians, Achaeans of Phthia, Thebans, and all the Boeotians except the men of Thespiae and Plataea. Against all of these the Greeks who declared war with the foreigner entered into a sworn agreement, which was this: that if they should be victorious, they would dedicate to the god of Delphi the possessions of all Greeks who had of free will surrendered themselves to the Persians. Such was the agreement sworn by the Greeks.
