Passage 4.18.5
οἱ μὲν δὴ ἄλλοι Μεσσηνίων ἐσπίπτοντες ἀπώλλυντο αὐτίκα, Ἀριστομένην δὲ ἔς τε τὰ ἄλλα θεῶν τις καὶ δὴ καὶ τότε ἐφύλασσεν· οἱ δὲ ἀποσεμνύνοντες τὰ κατʼ αὐτὸν Ἀριστομένει φασὶν ἐμβληθέντι ἐς τὸν Κεάδαν ὄρνιθα τὸν ἀετὸν ὑποπέτεσθαι καὶ ἀνέχειν ταῖς πτέρυξιν, ἐς ὃ κατήνεγκεν αὐτὸν ἐς τὸ πέρας οὔτε πηρωθέντα οὐδὲν τοῦ σώματος οὔτε τραῦμά τι λαβόντα. ἔμελλε δὲ ἄρα καὶ αὐτόθεν ὁ δαίμων ἔξοδον ἀποφαίνειν αὐτῷ.
The other Messenians, rushing in, perished immediately; but Aristomenes was protected by one of the gods both on other occasions and especially at this moment. Those who glorify Aristomenes' deeds declare that when he was thrown into the Ceadas, an eagle flew beneath him and supported him with its wings, carrying him down safely to the bottom without injury to his body or sustaining any wound. Indeed, even from that place, the divine power was later to reveal to him a way of escape.
