The book Aradia Gospel of the Witches by Charles G. Leland
(1899 and often reprinted) presented traditional witchcraft
teachings from Italy, which Leland claimed he obtained from
a Florentine fortune-teller and hereditary witch in the late
nineteenth century. This book is clearly one of the inspirations
of the modern witchcraft revival launched by Gerald B. Gardner,
and it has furnished some materials for the contemporary
witches Book of Shadows, the ritual book used by modern
Leland, Charles Godfrey. Aradia Gospel of the Witches. 1899.
