Great Demonology Information

Great old academic book on how cultures form demon and god mythologies and what happens when they are brought together. Goes into a lot of depth about religions all over the world and how they will adopt and absorb each other. Any reader will get a thorough overview of different devil-lore from every major influence. The concise but stimulating content will lay a good foundation to explore many aspects of theology, from Angel to demon and back again.
