I am taking Mr. Levack's classat UT, and of course this book is required reading. Regardless I would probably have gotten the book sooner or later. It is AMAZING. Extremely detailed, delves into both the magical and legal proceedings on the Witch hunt. The focus is on WHY something like this happened, and I feel Mr. Levack is incredibly inciteful in his ideas.
During the 70's and 80's, a flood of new information on historical witchcraft became available. Levack's book is the best survey of this new data, which has revolutionized our understanding of the Great Hunt. It's not a very "daring" book; it sticks to the facts, to the things we're sure about. There isn't a lot of speculation in it. But it's a great antidote to the badly researched books, like Anne Barstow's _Witchcraze_, which flood the popular market.
