The Sixth & Seventh Books of Moses was originally published in Germany in 1849. Its author, by the name of Johann Scheibel, is shrouded in mystery.
The author claimed that the seals and invocations given in the book came from ancient Hebrew sources, particularly the Talmud. It is not sure whether or not his claims were based on truth, although Talmudic scholars will probably deny that there are any references in Talmudic literature to The Sixth & Seventh Books of Moses.
While the original source of the book will probably never be ascertained, its popularity and durability can hardly be denied. The revised edition is an attempt at the reorganization of a work long hailed by occult masters as a valuable tool in the study and practice of cabalistic magic.
