The Encyclopedia of Demons and Demonology

The Encyclopedia of Demons and Demonology was published in 2009 as a comprehensive reference work detailing the cultural and historical presence of demonic entities across various religious and folkloric traditions. Written by Rosemary Guiley, an esteemed researcher in the fields of the paranormal and occult, the volume was designed to provide an objective, academic overview of its subject matter rather than acting as a grimoire or practical manual. It reflects Guiley's broader mission to catalog supernatural phenomena through a scholarly lens, documenting the evolution of demonic iconography from ancient Mesopotamia to contemporary popular culture.

The design of the encyclopedia adheres to a standard reference format, featuring alphabetized entries accompanied by historical illustrations and woodcuts that have come to define Western perceptions of the demonic. Upon its release, it was noted for its breadth and neutral tone, serving as a vital resource for writers, historians, and enthusiasts of occult history. Critics and readers alike praised the work for its accessibility, noting that it manages to synthesize complex theological concepts into a digestible format without sacrificing the depth of its research.
