Passage 2.9.8
τούτου δέ εἰσιν εἰκόνες ἐφεξῆς χαλκαῖ· τὰς Προίτου θυγατέρας λέγουσιν εἶναι σφᾶς, τὸ δὲ ἐπίγραμμα ἐς γυναῖκας ἄλλας εἶχεν. ἐνταῦθα Ἡρακλῆς χαλκοῦς ἐστι· Λύσιππος ἐποίησεν αὐτὸν Σικυώνιος, καὶ πλησίον Ἑρμῆς ἕστηκεν Ἀγοραῖος.
Next to this are bronze statues set up in succession: they say that these represent the daughters of Proetus, though the inscription upon them refers to other women. Here is also a bronze Heracles, made by Lysippos of Sikyon, and close by stands Hermes Agoraios.
