Throughout there will be short entries on individual demons, but Pandemonium will be more than just a visual encyclopedia. It will also focus on the influence of figures like Beelzebub, Azazel, Lilith, and Moloch on Western religion, literature, and art.

Ranging from the earliest scriptural references to demons in the New Testament through the Enlightenment and Romantic eras when our devils took on a subtler form, Pandemonium functions as a compendium of Lucifer's subjects from Dante's The Divine Comedy to John Milton's Paradise Lost, and all points in between. Containing rarely seen illustrations of very old treatises on demonology as well as more well-known works by the great masters of Western painting, this book will celebrate the art of hell like never before!
