Examines the ways in which people made sense of religious conversion during the 12th century, a critical point in the formation of Western moral values. The book also indicates that the understanding of conversions, rooted in medieval love of indirect and intricate allegorical symbolism, entered the permanent legacy of Western literature and art. The idea of conversion became a mythic strategy of survival in conflict against the world, the flesh and the devil. This book holds that the idea of conversion was a study in aesthetics, specifically in a male aesthetic, combining the brotherhood that violence engendered among warriors with the inexplicable genius of the poet. It explores the ascetic discipline, social myth, and representational art as components in a vast, militantly aggressive education system that served as context defining in the conversion process.
