Passage 8.31.3
ἔστι δὲ καὶ Ἡρακλῆς παρὰ τῇ Δήμητρι μέγεθος μάλιστα πῆχυν· τοῦτον τὸν Ἡρακλέα εἶναι τῶν Ἰδαίων καλουμένων Δακτύλων Ὀνομάκριτός φησιν ἐν τοῖς ἔπεσι. κεῖται δὲ τράπεζα ἔμπροσθεν, ἐπειργασμέναι τε ἐπʼ αὐτῇ δύο τέ εἰσιν Ὧραι καὶ ἔχων Πὰν σύριγγα καὶ Ἀπόλλων κιθαρίζων· ἔστι δὲ καὶ ἐπίγραμμα ἐπʼ αὐτοῖς εἶναι σφᾶς θεῶν τῶν πρώτων.
Beside Demeter is a statue of Heracles, about a cubit tall. Onomacritus asserts in his verses that this Heracles is one of those called the Idaean Dactyls. In front stands a table, on which are sculpted two Horae, Pan with pipes, and Apollo playing the lyre. There is also an inscription upon them, stating that they belong to the earliest of the gods.
