§12.12a.1ἐπὶ τῶν ἀθετούντων τὰς ὁμολογίας προφερόμεθα ταύτην τὴν παροιμίαν "Λοκροὶ τὰς συνθήκας. "τοῦτο δέ τις ἐξεύρηκεν ὅτι καὶ παρὰ τοῖς συγγραφεῦσι καὶ παρὰ τοῖς ἄλλοις ἀνθρώποις ὁμολογούμενόν ἐστι, §12.12a.2διότι κατὰ τὴν τῶν Ἡρακλειδῶν ἔφοδον συνθεμένων τῶν Λοκρῶν τοῖς Πελοποννησίοις πολεμίους πυρσοὺς αἴρειν, ἐὰν συμβῇ τοὺς Ἡρακλείδας μὴ κατὰ τὸν Ἰσθμόν, ἀλλὰ κατὰ τὸ Ῥίον ποιεῖσθαι τὴν διάβασιν, χάριν τοῦ προαισθομένους φυλάξασθαι τὴν ἔφοδον αὐτῶν, §12.12a.3οὐ ποιησάντων δὲ τῶν Λοκρῶν, πᾶν δὲ τοὐναντίον φιλίους ἀράντων πυρσούς, ὅτε παρῆσαν, τοὺς μὲν Ἡρακλείδας συνέβη μετʼ ἀσφαλείας χρῆσθαι τῇ διαβάσει, τοὺς δὲ Πελοποννησίους κατολιγωρήσαντας λαθεῖν παραδεξαμένους εἰς τὴν οἰκείαν τοὺς ὑπεναντίους παρασπονδηθέντας ὑπὸ τῶν Λοκρῶν.
Against those who disregard agreements, we quote this proverb, "The Locrians and the treaty." And someone has discovered that this is agreed upon both among writers and among other men, namely that, during the invasion of the Heracleidae, the Locrians agreed with the Peloponnesians to raise hostile signal-fires if it should happen that the Heracleidae made their crossing not by the Isthmus but by Rhium, for the purpose of their perceiving it beforehand and guarding against their invasion, but the Locrians did not do this, but on the contrary, when they arrived, raised friendly signal-fires, with the result that the Heracleidae succeeded in making their crossing in safety, while the Peloponnesians, having grown careless, were betrayed by the Locrians and unawares admitted their enemies into their own land.
