Passage 3.22.7
ἑορτὴν δὲ ἄγουσι τῷ θεῷ κατὰ ἔτος, ἐν ᾗ γυναιξίν ἐστιν ἀπηγορευμένον ἐσελθεῖν ἐς τὸ ἄλσος. περὶ δὲ τὴν ἀγοράν σφισιν αἱ πηγαὶ τῶν ποτίμων εἰσὶν ὑδάτων. ἐν δὲ τῇ ἀκροπόλει ναός ἐστιν Ἀπόλλωνος καὶ ἀγάλματος ἐλέφαντος πεποιημένου κεφαλή· τὰ δὲ λοιπὰ τοῦ ἀγάλματος πῦρ ἠφάνισεν ὁμοῦ τῷ προτέρῳ ναῷ.
They celebrate an annual festival in honor of the god, during which women are forbidden to enter the grove. Around the marketplace lie the springs of drinking water. On the acropolis there stands a temple of Apollo, and an image whose head is made of ivory. The remainder of the statue was destroyed by fire, along with the earlier temple.
