Passage 10.4.9
θαυμάσαι δὲ ἄξιον ὅτι ἐν τῇ γῇ ταύτῃ χελιδόνες οὔτε τίκτουσιν οὔτε ἐκλέπουσί γε τὰ ᾠά, οὐδʼ ἂν ἀρχὴν πρὸς οἰκήματος ὀρόφῳ νεοσσιὰν χελιδὼν ποιήσαιτο· λέγουσι δὲ οἱ Φωκεῖς ὡς τῇ Φιλομήλᾳ καὶ ὄρνιθι οὔσῃ Τηρέως δεῖμα ἐφάνη καὶ οὕτω τῆς πατρίδος ἀπέστη τῆς Τηρέως. Δαυλιεῦσι δὲ Ἀθηνᾶς ἱερὸν καὶ ἄγαλμά ἐστιν ἀρχαῖον· τὸ δὲ ξόανον τὸ ἔτι παλαιότερον λέγουσιν ἐπαγαγέσθαι Πρόκνην ἐξ Ἀθηνῶν.
It is worthy of wonder that in this land swallows neither lay eggs nor hatch them, nor would a swallow ever begin to build its nest upon the roof of a house. The Phocians say this is because Philomela, having become a bird, was so terrified of Tereus that she thus abandoned his homeland. At Daulis there is an ancient sanctuary and image of Athena; and the even older wooden statue, they say, was brought from Athens by Procne herself.
