'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. 'The Charge of the Goddess', an important piece of liturgy used in Wiccan rituals, was inspired by Aradia's speech in the first chapter of the book. Parts of the speech appeared in an early version of Gardnerian Wicca rituals.
