What Is a Demon
The category 'demon' covers an enormous range of supernatural malevolent beings across human cultures — from the Mesopotamian alu and utukku to the Christian fallen angels, the Japanese oni and tengu, the Islamic djinn, and the Hindu asuras. What unites them is their adversarial relationship to human wellbeing, their supernatural nature, and their role as agents of disruption and harm within their respective cosmological systems. The Western horror demon is primarily derived from Christian demonology but draws freely on other traditions for aesthetic and narrative effect.
Christian Demonology
Christian demonological tradition, developed through patristic theology and medieval texts, established the hierarchy of demons — Satan, Beelzebub, Asmodeus, Belphegor, Mammon, Leviathan, and the legions beneath them — that horror fiction and film draw from extensively. The Ars Goetia, a grimoire listing 72 demons with their sigils and attributes, has been a consistent source for horror aesthetics from medieval woodcuts to contemporary heavy metal imagery to horror film iconography.
Demons in Horror
The demon in horror cinema operates primarily as an agent of possession — from The Exorcist's Pazuzu to Hereditary's Paimon, the possession film gives the demonic tradition its most effective horror expression. The demon as external force invading the domestic space is the possession film's central image — the family home made alien by the presence of something ancient and malevolent that uses a beloved person as its vehicle.
