John Malalas, Chronographia, V
“The wise Euripides put in his poetic drama about the Cyclops that he had three eyes, indicating by this that he had three brothers and that they cared for one another and kept a watchful eye on one another’s places in the island, fought together, and avenged one another.
And he also adds that he made the Cyclops drunk and unable to flee, because Odysseus made that very Cyclops “drunk” with a ton of money and gifts so he would not “eat those with him up”, which is not actually to consume them with slaughter.
He also says that Odysseus blinded his one eye with torch fire, really meaning that he stole away the only daughter of Polyphemos’ brother, a maiden named Elpê, with “fire”, which means he seized her on fire with burning lust. This is what it means that he burned Polyphemos in one of his eyes, he really deprived him of his daughter. The very wise Pheidias of Corinth provided this interpretation saying that Euripides explained this poetically because he did not agree with what the wisest Homer said about the wandering of Odysseus.”
ὁ γὰρ σοφὸς Εὐριπίδης <ποιητικῶς> δρᾶμα ἐξέθετο περὶ τοῦ Κύκλωπος, ὅτι τρεῖς ἔσχεν ὀφθαλμούς, σημαίνων τοὺς τρεῖς ἀδελφοὺς (50 F 2) ὡς συμπαθοῦντας ἀλλήλοις καὶ διαβλεπομένους τοὺς ἀλλήλων τόπους τῆς νήσου καὶ συμμαχοῦντας καὶ ἐκδικοῦντας ἀλλήλους. (2) καὶ ὅτι οἴνωι μεθύσας τὸν Κύκλωπα ἐκφυγεῖν ἠδυνήθη, διότι χρήμασι πολλοῖς καὶ δώροις ἐμέθυσε τὸν αὐτὸν Κύκλωπα ὁ ᾽Οδυσσεὺς πρὸς τὸ μὴ κατεσθίειν τοὺς μετ᾽ αὐτοῦ, <τουτέστι μὴ καταναλίσκειν σφαγαῖς>. (3) καὶ ὅτι λαβὼν ᾽Οδυσσεὺς λαμπάδα πυρὸς ἐτύφλωσε τὸν ὀφθαλμὸν αὐτοῦ τὸν ἕνα, διὁτι τὴν θυγατέρα τὴν μονογενῆ τοῦ ἀδελφοῦ αὐτοῦ Πολυφήμου ῎Ελπην, παρθένον οὖσαν, λαμπάδι, πυρὸς ἐρωτικοῦ καυθεῖσαν ἥρπασε, τουτέστιν ἕνα τῶν ὀφθαλμῶν τοῦ Κύκλωπος ἐφλόγισε τὸν Πολύφημον τὴν αὐτοῦ θυγατέρα ἀφελόμενος. (4) ἥντινα ἑρμηνείαν ὁ σοφώτατος Φειδίας(?) ὁ Κορίνθιος ἐξέθετο, εἰρηκὼς ὅτι ὁ σοφὸς Εὐριπίδης ποιητικῶς πάντα μετέφρασε, μὴ συμφωνήσας τῶι σοφωτάτωι ῾Ομήρωι ἐκθεμένωι τὴν ᾽Οδυσσέως πλάνην.
Ok, this story might be totally nuts, but there was a scholiastic debate about how many eyes Polyphemos had.
