Passage 8.31.8
τοῦ ναοῦ δὲ τῶν Μεγάλων θεῶν ἐστιν ἱερὸν ἐν δεξιᾷ καὶ Κόρης· λίθου δὲ τὸ ἄγαλμα ποδῶν ὀκτὼ μάλιστα· ταινίαι δὲ ἐπέχουσι διὰ παντὸς τὸ βάθρον. ἐς τοῦτο τὸ ἱερὸν γυναιξὶ μὲν τὸν πάντα ἐστὶν ἔσοδος χρόνον, οἱ δὲ ἄνδρες οὐ πλέον ἢ ἅπαξ κατὰ ἔτος ἕκαστον ἐς αὐτὸ ἐσίασι. γυμνάσιον δὲ τῇ ἀγορᾷ συνεχὲς κατὰ ἡλίου δυσμάς ἐστιν ᾠκοδομημένον.
To the right of the temple of the Great Gods there is a sanctuary of Kore, and her statue, made of stone, is approximately eight feet high. Ribbons constantly encircle its pedestal. Women have perpetual access to this sanctuary, but men may enter it only once each year. Adjoining the marketplace on the west is a gymnasium.
