This is a powerful study of millenarian sects in Europe in the Middle Ages, and its images of armies of flagellants roaming the countryside, whipping themselves into a frenzy to gain God's forgiveness, alongside its subtle weaving of religion and politics, makes it one of the most exciting history books available. The reader really feels as if they are there, watching the wild, dark pageant whirl all around. (Kirkus UK)
