Raven Grimassi was a Neo-Pagan scholar and award-winning author of more than eighteen books on Witchcraft, Wicca, and Neo-Paganism. He was devoted to the study and practice of witchcraft for over forty years, and was co-founder and co-director of the Ash, Birch, and Willow tradition.
Grimassi's background included training in old forms of witchcraft as well as Brittic Wicca, the Pictish-Gaelic tradition, Italian Witchcraft, and Celtic Traditionalist Witchcraft. Raven was also a member of the Rosicrucian Order, and studied the Kabbalah through the First Temple of Tifareth under Lady Sara Cunningham.
Raven lived in New England with his wife and co-author Stephanie Taylor-Grimassi. Together, they directed The Fellowship of the Pentacle, a modern Mystery School devoted to preserving pre-Christian European spirituality.
