This contention, which undergirds most of his book, is entirely true: any strand of behavior that’s lasted throughout the whole length of human history is eminently worth serious study. And for the bulk of Magic, a History, that’s just what Gosden does. His inquiry looks back to prehistoric times and ranges across the whole breadth of the world, from ancient China to the Eurasian steppes to the long Middle Ages in Europe. His endeavor is to understand the role of magic in human societies over the sprawl of 40,000 years, and although that’s a mind-bogglingly enormous goal, the book pulls in a fascinating array of cultures and aspects of magic rites and rituals. The book’s central weakness is, unfortunately, its central tenet: 'Magical fictions are underpinned by magical fact.' There is no such thing as 'magical fact'.
