Aradia [EPUB ebook] 
or The Gospel of the Witches

’Aradia’ is perhaps the first 20th century text of Witchcraft revival. It is repeatedly cited as being profoundly influential to the development of Wicca. The text corroborates the thesis of Margaret Murray that early modern and Renaissance witchcraft represented a survival of ancient pagan beliefs.

Parts of the speech appeared in an early version of Gardnerian Wicca rituals
