Moreover, I think that the women were called doves by the people of Dodona for the reason that they were Barbarians and because it seemed to them that they uttered voice like birds; but after a time (they say) the dove spoke with human voice, that is when the woman began to speak so that they could understand; but so long as she spoke a Barbarian tongue she seemed to them to be uttering voice like a bird: for had it been really a dove, how could it speak with human voice?
