Passage 3.18.13
Ἥρα δὲ ἀφορᾷ πρὸς Ἰὼ τὴν Ἰνάχου βοῦν οὖσαν ἤδη, καὶ Ἀθηνᾶ διώκοντα ἀποφεύγουσά ἐστιν Ἥφαιστον. ἐπὶ δὲ τούτοις Ἡρακλέους πεποίηται τάξις τῶν ἔργων τῶν τὸ ἐς τὴν ὕδραν καὶ ὡς ἀνήγαγε τοῦ Ἅιδου τὸν κύνα. Ἀναξίας δὲ καὶ Μνασίνους, τούτων μὲν ἐφʼ ἵππου καθήμενός ἐστιν ἑκάτερος, Μεγαπένθην δὲ τὸν Μενελάου καὶ Νικόστρατον ἵππος εἷς φέρων ἐστίν. ἀναιρεῖ δὲ καὶ Βελλεροφόντης τὸ ἐν Λυκίᾳ θηρίον, καὶ Ἡρακλῆς τὰς Γηρυόνου βοῦς ἐλαύνει.
Hera is looking toward Io, daughter of Inachus, who is already transformed into a cow, and Athena is depicted fleeing from Hephaestus who pursues her. Following these scenes, there are representations of Heracles’ tasks, including his contest with the hydra and his fetching up the dog from Hades. Anaxias and Mnasinous are each shown mounted upon a horse, while Megapenthes, the son of Menelaus, and Nicostratus are both carried by a single horse. Bellerophon is shown killing the beast in Lycia, and Heracles is depicted driving away the cattle of Geryon.
