Passage 5.21.11
τοῦτον τὸν Νικόστρατον νήπιον παῖδα ἔτι ἐκ Πρυμνησσοῦ λῃσταὶ τῆς Φρυγῶν ἥρπασαν, οἰκίας ὄντα οὐκ ἀφανοῦς· κομισθέντα δὲ αὐτὸν ἐς Αἰγέας ὠνήσατο ὅστις δή. χρόνῳ δὲ ὕστερον τῷ ἀνδρὶ τούτῳ ὄνειρον γίνεται· λέοντος δὲ ἔδοξεν ὑπὸ τῷ σκίμποδι κατακεῖσθαι σκύμνον, ἐφʼ ᾧ ἐκάθευδεν ὁ Νικόστρατος. Νικοστράτῳ μὲν δή, ὡς ηὐξήθη, καὶ ἄλλαι νῖκαι καὶ Ὀλυμπίασιν ἐγένοντο παγκρατίου καὶ πάλης.
This Nikostratos was still a child when, while in Prymnessos, he was seized by Phrygian bandits, though belonging to a household not without prominence. Having been carried to Aegeae, he was bought there by a certain man. Some time afterward, this man had a dream: he thought that a lion’s cub was lying beneath the couch on which Nikostratos slept. When Nikostratos grew up, moreover, he won several victories, both in the pankration and in wrestling at Olympia.
