Raven Grimassi, the pen name of Gary Charles Erbe, was an American writer born in 1951 who became one of the most prolific voices in modern witchcraft publishing. Across more than twenty books he covered Wicca, witchcraft and neo-paganism, and he is credited with popularising Stregheria, the religious practice of witchcraft with roots in Italy, which he presented to readers through the lens of contemporary neo-paganism.
This was not armchair scholarship. Grimassi had been a practitioner of witchcraft for over forty-five years and served as co-director of the Ash, Birch and Willow tradition. He died of pancreatic cancer in March 2019, leaving behind a substantial and genuinely influential body of work.
