§2.171.1ἐν δὲ τῇ λίμνῃ ταύτῃ τὰ δείκηλα τῶν παθέων αὐτοῦ νυκτὸς ποιεῦσι, τὰ καλέουσι μυστήρια Αἰγύπτιοι.
On this lake they perform by night the representations of his sufferings, which the Egyptians call "mysteries".
περὶ μέν νυν τούτων εἰδότι μοι ἐπὶ πλέον ὡς ἕκαστα αὐτῶν ἔχει, εὔστομα κείσθω.
Now concerning these, though I know more details about how each of them is, let them be kept in holy silence.
§2.171.2καὶ τῆς Δήμητρος τελετῆς πέρι, τὴν οἱ Ἕλληνες θεσμοφόρια καλέουσι, καὶ ταύτης μοι πέρι εὔστομα κείσθω, πλὴν ὅσον αὐτῆς ὁσίη ἐστὶ λέγειν·
And concerning the rite of Demeter, which the Greeks call Thesmophoria, concerning this too let it be kept in holy silence by me, except so much of it as it is lawful to speak.
§2.171.3αἱ Δαναοῦ θυγατέρες ἦσαν αἱ τὴν τελετὴν ταύτην ἐξ Αἰγύπτου ἐξαγαγοῦσαι καὶ διδάξασαι τὰς Πελασγιώτιδας γυναῖκας· μετὰ δὲ ἐξαναστάσης πάσης Πελοποννήσου ὑπὸ Δωριέων ἐξαπώλετο ἡ τελετή, οἱ δὲ ὑπολειφθέντες Πελοποννησίων καὶ οὐκ ἐξαναστάντες Ἀρκάδες διέσωζον αὐτὴν μοῦνοι.
It was the daughters of Danaus who brought this rite out of Egypt and taught it to the Pelasgian women; but afterwards, when the whole Peloponnese was depopulated by the Dorians, the rite perished, and those of the Peloponnesians who were left behind and not driven out, namely the Arcadians, alone preserved it.
