Magliocco calls "Aradia" "the first real text of the 20th century Witchcraft revival", and it is repeatedly cited as being profoundly influential on the development of Wicca. The text apparently corroborates the thesis of Margaret Murray that early modern and Renaissance witchcraft represented a survival of ancient pagan beliefs, and after Gerald Gardner's claim to have encountered religious witchcraft in 20th-century England, the works of Michelet, Murray, and Leland helped support at least the possibility that such a survival could exist.
