Passage 10.8.5
πέμπουσι δὲ καὶ Λοκροὶ οἵ τε καλούμενοι Ὀζόλαι καὶ οἱ πέραν Εὐβοίας ἕνα ἑκάτεροι, καὶ Εὐβοεύς ἐστιν εἷς· Πελοποννησίων δὲ ἐξ Ἄργους καὶ Σικυῶνος καὶ Κορίνθου σὺν Μεγαρεῦσίν ἐστιν εἷς καὶ εἷς Ἀθηναῖος. αἱ μὲν δὴ πόλεις Ἀθῆναι καὶ Δελφοὶ καὶ ἡ Νικόπολις, αὗται μὲν ἀποστέλλουσι συνεδρεύσοντας ἐς Ἀμφικτυονίαν πᾶσαν· ἀπὸ δὲ ἐθνῶν τῶν κατειλεγμένων ἑκάστῃ πόλει ἀνὰ μέρος ἐς Ἀμφικτύονας καὶ ἐν χρόνου περιόδῳ συντελεῖν ἔστιν.
The Lokrians also send deputies, one from the so-called Ozolian Lokrians and one from those beyond Euboea, and there is one from Euboea itself. Of the Peloponnesians, Argos, Sicyon, and Corinth, together with Megara, send one representative among them, and Athens sends one separately. As for the cities of Athens, Delphi, and Nicopolis, these send deputies to participate in every meeting of the Amphictyonic Council. From each of the aforementioned groups of peoples, the various cities take turns in appointing representatives to the Amphictyonic Council and share responsibility periodically.
