Passage 6.24.7
ἔχειν δὲ αὐτὰς ἐπὶ τοιῷδε εἰκάζοι τις ἂν τὰ εἰρημένα, ῥόδον μὲν καὶ μυρσίνην Ἀφροδίτης τε ἱερὰ εἶναι καὶ οἰκεῖα τῷ ἐς Ἄδωνιν λόγῳ, Χάριτας δὲ Ἀφροδίτῃ μάλιστα φίλας εἶναι θεῶν· ἀστράγαλον δὲ μειρακίων τε καὶ παρθένων, οἷς ἄχαρι οὐδέν πω πρόσεστιν ἐκ γήρως, τούτων εἶναι τὸν ἀστράγαλον παίγνιον. τῶν Χαρίτων δὲ ἐν δεξιᾷ ἄγαλμά ἐστιν Ἔρωτος· ἕστηκε δὲ ἐπὶ βάθρου τοῦ αὐτοῦ.
One might conjecture that their attributes carry the following significance: the rose and myrtle are both sacred to Aphrodite, and connected with the story of Adonis; while among the gods, the Graces are especially dear to Aphrodite. As for the knucklebone, it is a toy appropriate for youths and maidens, who have as yet no unpleasantness due to old age. Beside the Graces, on their right, stands a statue of Eros, placed upon the same pedestal.
