Question for Wiccans: who wrote the Book Of Shadows?
Gerald Gardner, the founder of the religion, compiled the first Book of Shadows from various sources, with the input of Doreen Valiente. Since then each Tradition has created its own and each individual Wiccan usually keeps their own version of the BoS, which is a journal/diary of one’s rituals, liturgy, recipes, elemental correspondences, and so forth.
