Note 386 — Chapter IV · THE WOMEN’S FESTIVALS. Thesmophoria, Arrephoria, Skirophoria, Stenia, Haloa.
Reading edition
The exact formulary is preserved by Theon of Smyrna, p. 22, τὸ κήρυγμα τοῦτο κηρύττεται ‘ὅστις τὰς χεῖρας μὴ καθαρός ... ὅστις φωνὴν ἀσύνετος.’ Some authorities think that φωνὴν ἀσύνετος means speaking an unknown, barbarous tongue, others that it meant having some impediment of speech that prevented the due utterance of the sacred formularies. I think the former more probable.
