About this book
What turns a shadow into a spirit, or a strange dream into a warning?
In Demonologia, J. S. Forsyth explores beliefs in spirits, omens, witchcraft and haunting. Sickness, storms and sudden death become reasons to fear unseen powers. Behind these beliefs lies a human need to explain what feels mysterious, threatening or beyond control.
Strange tales meet plain explanations as Forsyth considers fear, fever, poor light, memory and imagination. The book traces ancient ideas into later folk custom and asks why they endure. What makes a vision feel real, and why does an omen keep its hold even when reason offers another answer?

In short
Why did Roman commanders consult augurs before they marched? Demonologia gathers the beliefs that once ruled daily life, from omens and amulets to ghosts, witches and devils.
From the 15-minute summary · Key idea 1
Superstition is older than reason
The book opens with a bold claim. The human mind is drawn to the marvelous, and old superstitions survive even where learning has spread. Greek and Roman heroes and statesmen obeyed augurs, oracles and soothsayers. Kings and commanders would not march without reading entrails, birds and chickens.
Then the author turns the mirror on his own time. A hare on the road, spilled salt and a stumble are old omens, many inherited from Greece and Rome. People of sound judgment still turn pale at them.

What is Demonologia about?
It is a collection of essays and dictionary-style entries on superstition. Topics include omens, astrology, amulets, alchemy, oracles, ghosts, witches, devils, saints and relics, with many anecdotes from ancient and early modern writers.
Who wrote Demonologia and when?
It is credited to J. S. Forsyth. It leans heavily on older authors, quoting and summarizing many of them, so it works as a compiled survey rather than a single argument.
Is Demonologia a true account of witches and ghosts?
It reports many old stories of witch trials, hauntings and apparitions, but the author usually offers natural explanations such as dreams, illness, fear and fraud. It records what people believed rather than proving it.
