Juba, BNJ 275 F 5 (=Pseudo-Plutarch, Parallel Stories 23 p. 311b-c)
“After the destruction of Troy, Diomedes was shipwrecked in Libya where the king was Lykos. He had the custom of sacrificing foreigners to his father Ares. But Kallirhoe, his daughter, betrayed her father because she was infatuated with Diomedes.
She saved Diomedes by releasing him from his chains. But he sailed away without any concern for the woman who helped him and she killed herself by hanging. That is the story of Juba in the third book of his Libyan Tales.”
Μετὰ τὴν ᾽Ιλίου πόρθησιν ἐξεράσθη Διομήδης εἰς Λιβύην, ἔνθα Λύκος ἦν βασιλεύς, ἔθος ἔχων τοὺς ξένους ῎Αρει τῶι πατρὶ θύειν. Καλλιρρόη δὲ ἡ θυγάτηρ ἐρασθεῖσα Διομήδους τὸν πατέρα προύδωκε, καὶ τὸν Διομήδην ἔσωσε λύσασα τῶν δεσμῶν. ὁ δὲ ἀμελήσας τῆς εὐεργέτιδος ἀπέπλευσεν, ἡ δὲ βρόχωι ἐτελεύτησεν, ὡς ᾽Ιόβας ἐν τρίτηι Λιβυκῶν.
Scholia to Lykophron Alexandra 615
“After Troy was sacked, Diomedes threw stones from the walls of Troy into his ship for ballast. When he arrived in Argos and went unnoticed by Aigialeia, his wife, he went to Italy. When he found a Skythia dragon laying waste to Phaiacia, he killed it as he held Glaukos’ golden shield (and the dragon thought the shield was the golden skin of the ram).
Diomedes was especially honored for this act and he made a statue, shaping it from the stones taken from Troy. Timaios tells this story and Lykos does too in his third book. Later on, Daunos killed Diomedes and threw the statues into the sea. But they returned again over the waves and proceeded back to their bases. That’s the story, at least.”
ἁλούσης τῆς ᾽Ιλίου, Διομήδης ἀντὶ τοῦ ἕρματος ἐκ τοῦ τείχους τῶν Τρώων λίθους εἰς τὴν ναῦν ἐβάλετο. παραγενόμενος δὲ εἰς τὸ ῎Αργος καὶ ἐλαθεὶς ὑπὸ Αἰγιαλείας τῆς γαμετῆς παρεγένετο εἰς ᾽Ιταλίαν. εὑρὼν δὲ τηνικαῦτα τὸν ἐν τῆι Σκυθίαι δράκοντα λυμαινόμενον τὴν Φαιακίδα, διέφθειρε τοῦτον, τὴν τοῦ Γλαύκου χρυσῆν ἀσπίδα κατέχων, νομίσαντος τοῦ δράκοντος τὸ χρυσοῦν δέρας εἶναι τοῦ κριοῦ. τιμηθεὶς δὲ ἐπὶ τούτωι σφόδρα, ἀνδριάντα κατασκευάσας, ἱδρύσατο ἐκ τῶν λίθων τῶν ἐκ τῆς ᾽Ιλίου. ἱστορεῖ δὲ τοῦτο Τίμαιος καὶ Λύκος ἐν τῶι τρίτωι. ὕστερον δὲ ἀνελὼν ὁ Δαῦνος αὐτόν, ἔρριψε καὶ τοὺς ἀνδριάντας εἰς θάλασσαν· οὗτοι δὲ ἀνεχόμενοι τὰ κύματα, πάλιν ἐξήρχοντο πρὸς τὰς βάσεις αὐτῶν. καὶ ἡ μὲν ἱστορία τοιαύτη.
