Scourge of Demons: Terrible, Most Powerful, and Effective Exorcisms

First printed in the 16th century, Hieronymus Mengus’s Scourge of Demons (Flagellum Daemonum) is one of the most dreaded manuals of exorcism ever penned. Written as both weapon and warning, it offers priests a fearsome arsenal of prayers, adjurations, and rites designed to drive out demons, break curses, and shield the afflicted from infernal torment.

Every page burns with urgency: invocations that call upon divine authority, commands that strike at the heart of demonic pride, and rituals crafted to protect body and soul alike. Yet the book also breathes danger—for Mengus makes clear that to wield these rites without purity, courage, and faith is to invite destruction.

Revered by some as a holy safeguard, reviled by others as too perilous to handle, Scourge of Demons has echoed through centuries as a cornerstone of Catholic exorcism and demonology. To study it is to step into a battlefield where victory and ruin lie perilously close.
