This was a German magical handbook first published in Stuttgart in 1849. It became famous in American folk magic and voodoo. The text of the supposed Sixth and Seventh Books consumed just twenty-two pages, the remaining 168 are filled with essays on magical history and theory, collections of Kabbalist talismans, and explanations of the magical usage of psalms and similar material.
It was first popular among the Pennsylvania Dutch and other German communities in the United States. The Stuttgart edition was being reprinted in the 1850s and English translations were available by 1880. Within a decade it gained popularity among the voodoo populations in America and the West Indies from which it gained its legendary reputation. A.G.H.
