Gustav Meyrink (1868-1932) was considered a specialist in occult teachings and secret societies, which shaped his work since his greatest success, "The Golem," published in 1915. This is also true for the novel "The Angel from the Western Window," published in 1927, which centers around the teachings of the Rosicrucians, a loose association of various esoteric secret societies that dealt with Kabbalistic studies, theosophy, magic, and alchemy.
