Passage 10.5.5
ἡ δὲ λεωφόρος αὐτόθεν ἡ ἐς Δελφοὺς καὶ προσάντης γίνεται μᾶλλον καὶ ἀνδρὶ εὐζώνῳ χαλεπωτέρα. λέγεται δὲ πολλὰ μὲν καὶ διάφορα ἐς αὐτοὺς τοὺς Δελφούς, πλείω δὲ ἔτι ἐς τοῦ Ἀπόλλωνος τὸ μαντεῖον. φασὶ γὰρ δὴ τὰ ἀρχαιότατα Γῆς εἶναι τὸ χρηστήριον, καὶ Δαφνίδα ἐπʼ αὐτῷ τετάχθαι πρόμαντιν ὑπὸ τῆς Γῆς·
From that point onward, the road to Delphi becomes steeper and more difficult for a lightly equipped traveler. Many differing tales are reported concerning the Delphians themselves, but even more numerous accounts refer to the oracle of Apollo. They assert that the most ancient oracle was originally that of Earth, and that Daphnis was appointed by Earth herself as prophetess at this place.
