Classen explores the secret as a compelling narrative device in medieval texts. His focus is not on magical and religious elements per se, but rather on the ways in which medieval writers grappled with unknowable, or secret, objects and events. Classen discusses not only characters who wield secret knowledge and powers, but also those affected by, but not privy to, those secrets. The comprehensive introduction defines the significance of secrecy throughout literary studies, and the chapters that follow are devoted to an array of writers and genres. Recommended. Upper-division undergraduates through faculty.
