Passage 2.10.5
τὸ μὲν δὴ ἄγαλμα καθήμενον Κάναχος Σικυώνιος ἐποίησεν, ὃς καὶ τὸν ἐν Διδύμοις τοῖς Μιλησίων καὶ Θηβαίοις τὸν Ἰσμήνιον εἰργάσατο Ἀπόλλωνα· πεποίηται δὲ ἔκ τε χρυσοῦ καὶ ἐλέφαντος, φέρουσα ἐπὶ τῇ κεφαλῇ πόλον, τῶν χειρῶν δὲ ἔχει τῇ μὲν μήκωνα τῇ δὲ ἑτέρᾳ μῆλον. τῶν δὲ ἱερείων τοὺς μηροὺς θύουσι πλὴν ὑῶν, τἄλλα δὲ ἀρκεύθου ξύλοις καθαγίζουσι, καιομένοις δὲ ὁμοῦ τοῖς μηροῖς φύλλον τοῦ παιδέρωτος συγκαθαγίζουσιν.
The seated statue was created by Kanachos of Sikyon, who also fashioned the Apollo at Didyma of the Milesians, as well as the Ismenian Apollo at Thebes. It is made from gold and ivory; on her head she bears a polos, and in her hands she carries a poppy in one hand and an apple in the other. As for sacrifices, they burn the thighs of victims except those of pigs, and the other portions they consecrate by burning them with juniper wood; along with the thighs they also offer up leaves of the peony plant.
