A Book of Shadows is a book containing religious texts and instructions for magical rituals found within the Neo-pagan religion of Wicca. The first Book of Shadows was created by Gerald B. Gardner, (an author as well as an amateur archaeologist and anthropologist), in the late 1940's or early 1950's, which he used in his Bricket Wood coven and then in later covens which he founded. The concept was adopted by other traditions. The current Book of Shadows is a compilation of manuscripts found in his museum after his death.
