Passage 1.31.1
δῆμοι δὲ οἱ μικροὶ τῆς Ἀττικῆς, ὡς ἔτυχεν ἕκαστος οἰκισθείς, τάδε ἐς μνήμην παρείχοντο· Ἀλιμουσίοις μὲν Θεσμοφόρου Δήμητρος καὶ Κόρης ἐστὶν ἱερόν, ἐν Ζωστῆρι δὲ ἐπὶ θαλάσσης καὶ βωμὸς Ἀθηνᾶς καὶ Ἀπόλλωνος καὶ Ἀρτέμιδος καὶ Λητοῦς. τεκεῖν μὲν οὖν Λητὼ τοὺς παῖδας ἐνταῦθα οὔ φασι, λύσασθαι δὲ τὸν ζωστῆρα ὡς τεξομένην, καὶ τῷ χωρίῳ διὰ τοῦτο γενέσθαι τὸ ὄνομα. Προσπαλτίοις δέ ἐστι καὶ τούτοις Κόρης καὶ Δήμητρος ἱερόν, Ἀναγυρασίοις δὲ Μητρὸς θεῶν ἱερόν· Κεφαλῆσι δὲ οἱ Διόσκουροι νομίζονται μάλιστα, Μεγάλους γὰρ σφᾶς οἱ ταύτῃ θεοὺς ὀνομάζουσιν.
The small demes of Attica, founded each according to chance, provide the following noteworthy places: the Halimousians have a sanctuary of Demeter Thesmophoros and Kore. In Zoster, near the sea, there stands an altar dedicated to Athena, Apollo, Artemis, and Leto. They do not say that Leto actually bore her children here, but rather that she loosened her girdle at this spot, preparing herself for childbirth; hence the district received its name. At Prospalta too, there is a temple sacred to Kore and Demeter, and at Anagyrus a sanctuary of the Mother of the Gods. Among the Kephalenses, the Dioskouroi receive special veneration, and the people here call them the "Great Gods."
