The last twenty-five years have seen an explosion of scholarly studies on lollardy, the late medieval religious phenomenon that has often been credited with inspiring the English Reformation. In A Companion to Lollardy, Patrick Hornbeck sums up what we know about lollardy and what have been its fortunes in the hands of its most recent chroniclers. This volume describes trends in the study of lollardy and explores the many individuals, practices, texts, and beliefs that have been called lollard.Joined by Mishtooni Bose and Fiona Somerset, Hornbeck assesses how scholars and polemicists, literary critics and ecclesiastics have defined lollardy and evaluated its significance, showing how lollardy has served as a window on religion, culture, and society in late medieval England.
