What it is

This book is the most well-known historical document about witchcraft. It was written by Heinrich Kramer, a Catholic priest from Germany. The title translates to Hammer of Witches. Many scholars see it as a collection of earlier ideas rather than a new invention. It claims to represent the official view of the Church. However, it was actually rejected by many church leaders. The text focuses on how to identify and punish those accused of magic.

Where it comes from

Heinrich Kramer wrote this book after failing to prosecute witches in Tyrol. He was expelled from Innsbruck and called crazy by local bishops. He wrote this text to justify his actions and prove that witchcraft was real. He wanted to convince judges to use his specific methods for finding witches. Some people later claimed Jacob Sprenger helped write it, but this is debated. The book was first printed in Speyer in 1486.

How it is done

The text provides a legal framework for accusing people of heresy through magic. It suggests using torture to force confessions from the accused. It argues that death is the only way to stop the evil caused by witches. Secular courts used these rules to try people. The Inquisition did not use this book because they rejected its methods. The book treats witchcraft as a serious crime against God and society.

Tools and materials

The main tool is the Latin text itself. It includes a papal bull from Pope Innocent VIII. This bull gives authority to Kramer and Sprenger. It also includes a fake approval letter from the University of Cologne. These documents were used to give the book an air of official power. The text relies on religious arguments about demons and Satan.
