Stregheria, or the Strega tradition of modern Italian Wiccan-styled witchcraft
Grimassi shares in common, in his books, the general "Witch-cult hypothesis" that appears in the writings of Charles G. Leland (Aradia, or the Gospel of the Witches, 1899), a theory to the effect that European witchcraft was the continuation of an ancient pre-Christian form.
Burchard's mention of Herodias is relevant especially the theories of Charles Godfrey Leland presented in Aradia, or the Gospel of the Witches (1899), and taken up in the Stregheria of Raven Grimassi.
