Unlike most of the reviewers here, I come from a different starting place. I knew Margaret Murray. She lived to be a hundred years old and died in 1963.
It's a shame that she's known mostly now for her books on witches. She was an Egyptologist and did valuable work back in the late 1890's with Sir Matthew Finders Petrie.
This book is not one of her best. She was cantankerous to say the least. She would agree with me, if she were able. Sorry, Margaret.....
Murray's book actually contains a statement to the effect of "What reason would there have been for anyone to be accused of witchcraft other than that they were a witch?" and its entire argument is based on testimonies extracted under torture by people who were using the _Malleus Maleficarum_ as a guide, and would not accept any answers except what the book told them to expect.
The main reason to own this book today is for its place in the history of ideas about European Paganism.
