Some solitary Wiccans also perform self-initiation rituals, to dedicate themselves to becoming a Wiccan. The first of these to be published was in Paul Huson's Mastering Witchcraft (1970), and unusually involved recitation of the Lord's Prayer backwards as a symbol of defiance against the historical Witch Hunt.[6] Subsequent, more overtly pagan self-initiation rituals have since been published in books designed for solitary Wiccans by authors like Doreen Valiente, Scott Cunningham and Silver RavenWolf.[citation needed]
