'' Sinal do Labrys '' de Margaret St. Clair, publicado em 1963
Her protagonist, Sam Sewell lives in a post-apocalyptic world, a world where horrific yeast based diseases killed off most people.
....
Despoina in the meanwhile is not quite what the FBY agent told Sam. Sam soon learns she is a Witch, though not the sort of witch Sam first thinks of, the stereotypical old hag who rides a broomstick. What she is, is what we now would call Wiccan, something that the title of the novel hints of already. A Labrys is a double headed ritual axe, as used in Minoan religious rites in ancient Greece and later adopted by neopagans. Sam Sewell, as you may guess has to be initiated into Witchhood and Despoina is the person who has to lead him to the Craft. Witches have of course superhuman powers and they need Sam to help better the world. Their opponents being the FBY, who are busy trying to establish a dictatorship.
