Clement of Alexandria, Protreptikos, 4.47.6
“Many would probably be amazed if they learned that the Palladion, reportedly heaven sent, which Diomedes and Odusseus are said to have taken from Troy and then gave to Demophon, was made of Pelops’s bones, just as the Olympion was made from various bones of an Indian animal. I rely on Dionysus for this, who reports it in the fifth book of his Cycle.”
πολλοὶ δ᾽ ἂν τάχα που θαυμάσειαν, εἰ μάθοιεν τὸ Παλλάδιον τὸ διοπετὲς καλούμενον, ὃ Διομήδης καὶ ᾽Οδυσσεὺς ἱοτοροῦνται μὲν ὑφελέσθαι ἀπὸ ᾽Ιλίου, παρακαταθέσθαι δὲ Δημοφῶντι, ἐκ τῶν Πέλοπος ὀστῶν κατεσκευάσθαι, καθάπερ τὸν ᾽Ολύμπιον ἐξ ἄλλων ὀστῶν ᾽Ινδικοῦ θηρίου. καὶ δὴ τὸν ἱστοροῦντα Διονύσιον ἐν τῶι πέμπτωι μέρει τοῦ Κύκλου παρίστημι.
