An excellent starting point for understanding Western occultism. Move forward from here - hitting other high points over the next five hundred years, including:
1) John Dee and Edward Kelly (late 1500s)- many books available on the history and fruits of their brief but intense collaboration.
2) Rosicrucian manifestos (early 1600s; authorship unknown, typically assigned to the name 'Christian Rosenkreutz') - available from many internet sources.
3) Count Cagliostro (aka Joseph Balsamo; 1700s) - mostly biographical works.
4) Adam Weishaupt & Illuminati sects (1700s)- mostly biographical and historical works.
5) Emanuel Swedenborg (1700s)
6) Paschal Beverly Randolph (1800s) - probably the most important, influential occultist to come out of the American spirituality movement of that century. Many of his works are in the public domain.
7) Eliphas Levi (1800s) - French occultist with large output, mostly a synthesizer.
