Passage 4.26.7
Ἐπαμινώνδᾳ μὲν ταῦτα ἔλεγεν, Ἐπιτέλει δὲ τῷ Αἰσχίνου τάδε ἐμήνυε---στρατηγεῖν δὲ αὐτὸν οἱ Ἀργεῖοι τὸν Ἐπιτέλην καὶ Μεσσήνην ἀνοικίζειν ᾕρηντο--- τοῦτον οὖν τὸν ἄνδρα ἐκέλευεν ὁ ὄνειρος, ἔνθα ἂν τῆς Ἰθώμης εὕρῃ πεφυκυῖαν σμίλακα καὶ μυρσίνην, τὸ μέσον ὀρύξαντα αὐτῶν ἀνασῶσαι τὴν γραῦν· κάμνειν γὰρ ἐν τῷ χαλκῷ καθειργμένην θαλάμῳ καὶ ἤδη λιποψυχεῖν αὐτήν. ὁ δὲ Ἐπιτέλης, ὡς ἐπελάμβανεν ἡμέρα, παραγενόμενος ἐς τὸ εἰρημένον χωρίον ἐπέτυχεν ὀρύσσων ὑδρίᾳ χαλκῇ, καὶ αὐτίκα παρὰ τὸν Ἐπαμινώνδαν
These words he spoke to Epaminondas; but to Epiteles, the son of Aeschines—whom the Argives had chosen as their general to resettle Messene—the dream gave the following message: it bid this man, wherever on Ithome he found a growing ivy and myrtle, to dig between them and rescue the old woman, who lay exhausted and close to fainting, imprisoned in a bronze chamber. Therefore Epiteles, as soon as day dawned, went to the appointed place and began digging; he quickly chanced upon a bronze water-urn, and then immediately went to Epaminondas.
