What turns a storm into a demon, an old god into an enemy, and fear into a witch hunt?
In Demonology and Devil-Lore, Moncure Daniel Conway follows the devil through myths, customs and religious traditions. His study moves from gods of storm and darkness to evil spirits in Persia, India, Egypt and Hebrew tradition. Serpents, goats and demons of disease reveal how people give fear a shape.
Conway writes as a freethinker with firm opinions, asking where the devil comes from and why cultures need him. He explores Ahriman in the religion of Zoroaster, the Christian story of Satan and hell, and the trials of accused witches. His central argument links these beliefs to human experience.

From the 15-minute summary · Key idea 1
Evil began when a united heaven split
Conway opens with a piece of advice, orient thyself. To read old myths, he says, we must picture a world without scientific eyes, where the sun is a chariot and a spirit lives in every tree. Worship began with wonder at the sky, not with logs and stones.
The oldest hymns of the Rig-Veda are cheerful. Storm gods are praised beside the sun god, and one verse says no real foe is known in heaven. Conway calls this early pantheism the counterpart of ignorance. It is a mind that has not yet learned to tell good from evil.

What is Demonology and Devil-Lore about?
It traces how demons, dragons, witches and the Devil arose from fear, nature and religious rivalry. Conway draws on myths from India, Persia, Egypt, Scandinavia, Palestine and Christian Europe, and argues that most demons began as gods.
What is the difference between a demon and a devil?
For Conway, a demon harms for a reason, like hunger or desire, and has no moral purpose. A devil loves evil for its own sake, an idea that needs a developed moral sense and appears much later.
What does Conway mean by saying demons were once gods?
He shows through names and stories that many demons carry traces of divine origin. Deva means god in India and devil in Persia, Lucifer means light-bearing, and Beelzebub began as Baal-zebub, a fly-god of the Philistines.
