Passage 1.34.2
λέγεται δὲ Ἀμφιαράῳ φεύγοντι ἐκ Θηβῶν διαστῆναι τὴν γῆν καὶ ὡς αὐτὸν ὁμοῦ καὶ τὸ ἅρμα ὑπεδέξατο· πλὴν οὐ ταύτῃ συμβῆναί φασιν, ἀλλά ἐστιν ἐκ Θηβῶν ἰοῦσιν ἐς Χαλκίδα Ἅρμα καλούμενον. θεὸν δὲ Ἀμφιάραον πρώτοις Ὠρωπίοις κατέστη νομίζειν, ὕστερον δὲ καὶ οἱ πάντες Ἕλληνες ἥγηνται. καταλέξαι δὲ καὶ ἄλλους ἔχω γενομένους τότε ἀνθρώπους, οἳ θεῶν παρʼ Ἕλλησι τιμὰς ἔχουσι, τοῖς δὲ καὶ ἀνάκεινται πόλεις, Ἐλεοῦς ἐν Χερρονήσῳ Πρωτεσιλάῳ, Λεβάδεια Βοιωτῶν Τροφωνίῳ· καὶ Ὠρωπίοις ναός τέ ἐστιν Ἀμφιαράου καὶ ἄγαλμα λευκοῦ λίθου.
They say that when Amphiaraus was fleeing from Thebes, the earth opened up and received both him and his chariot; yet they affirm that this event occurred not at this spot, but at a place called Harma ("Chariot") on the road leading from Thebes to Chalcis. It was the Oropians who first established the worship of Amphiaraus as a god, but afterwards all the Greeks respected him as divine. I could also list other men of past times who have received divine honors among the Greeks and even have cities dedicated to them—for instance, Protesilaus at Elaeus in the Chersonese and Trophonius at Lebadeia in Boeotia. Likewise, the Oropians have a temple for Amphiaraus and a statue of him made from white stone.
