Mystery Cults of the Ancient World, published April 2010, by Princeton University Press, Hugh Bowden systematically reviews literature, anthropology, and archaeology to provide a picture of what we know of the ancient mystery religions. He begins with ordinary religion then and now, distinguishing between modern-style religions -- especially religions of the Book -- and ancient, gods-based ones where individuals and communities had transactional relationships with supernatural beings who could make a difference in their lives.

This book sounds fascinating–it’s going on my ever-expanding “To Read” list.
Since it contains some Roman religious material and could use multiple reads, perhaps we could suggest it as a Roman History Book Chat book — once it gets a bit older.
My initial reaction to this, I kid you not, was “OhmyGods, I so need this book!” (I consider myself a Neo-Pagan and have been interested in how the ancient Greeks and Romans lived their religion.) I don’t know if the ancients would have been pleased by that or not. I do know I’m ordering this and the book about ancient Greek priestesses that you mentioned in the review when I get paid next week. Thank you for bringing it to the attention of those of us who want it!
