“Renate Blumenfeld-Kosinski writes with a real sympathy for her subjects, who emerge as flesh-and-blood humans struggling to make sense of a profound crisis that threatens to undermine their faith in the clergy. No book more vividly tells the story of the Great Schism or brings together a more fascinating set of characters and texts from the period. I can think of no finer introduction to the workings of the minds of medieval people than Poets, Saints, and Visionaries.”—Laura Ackerman Smoller, University of Arkansas at Little Rock
