Passage 9.39.4
τὰ δὲ ἐπιφανέστατα ἐν τῷ ἄλσει Τροφωνίου ναὸς καὶ ἄγαλμά ἐστιν, Ἀσκληπιῷ καὶ τοῦτο εἰκασμένον· Πραξιτέλης δὲ ἐποίησε τὸ ἄγαλμα. ἔστι δὲ καὶ Δήμητρος ἱερὸν ἐπίκλησιν Εὐρώπης καὶ Ζεὺς Ὑέτιος ἐν ὑπαίθρῳ. ἀναβᾶσι δὲ ἐπὶ τὸ μαντεῖον καὶ αὐτόθεν ἰοῦσιν ἐς τὸ πρόσω τοῦ ὄρους, Κόρης ἐστὶ καλουμένη θήρα καὶ Διὸς Βασιλέως ναός. τοῦτον μὲν δὴ διὰ τὸ μέγεθος ἢ καὶ τῶν πολέμων τὸ ἀλλεπάλληλον ἀφείκασιν ἡμίεργον· ἐν δὲ ἑτέρῳ ναῷ Κρόνου καὶ Ἥρας καὶ Διός ἐστιν ἀγάλματα. ἔστι δὲ καὶ Ἀπόλλωνος ἱερόν.
The most notable things in the grove are the temple and statue of Trophonius, which statue resembles Asklepios; this sculpture is the work of Praxiteles. There is also a sanctuary of Demeter, surnamed Europa, and Zeus Hyetios ("God of Rain"), set up in the open air. Proceeding up towards the oracle and then forward from there to the higher part of the mountain, there stands what is called the Thera ("Hunt") of Kore and a temple of Zeus Basileus ("the King"). This temple, indeed, has been left half-finished, owing perhaps to its great size or to wars continually breaking out. Within another temple are statues of Kronos, Hera, and Zeus. There is also a sanctuary of Apollo.
