 Perhaps the most notable of these was the Protestant pastor Georg Conrad Horst (1779–1832), who from 1821 to 1826, published a six-volume collection of magical texts in which he studied grimoires as a peculiarity of the Mediaeval mindset.Another scholar of the time interested in grimoires, the antiquarian bookseller Johann Scheible, first published the "Sixth and Seventh Books of Moses", two influential magical texts that claimed to have been written by the ancient Jewish figure Moses.
