The Doctrine of the Hert was the fifteenth-century English translation of De doctrina cordis, the thirteenth-century Latin devotional treatise addressed to nuns. The text progressively pairs the seven gifts of the Holy Spirit with seven key actions of the heart, leading readers toward contemplative unity with God. The text was a religious bestseller. It circulated widely throughout Europe between the thirteenth and fifteenth centuries and was translated into numerous vernacular versions. This book consists of ten essays from an international group of scholars of medieval religion discussing the Middle English text alongside its Latin forebear, and other European vernacular translations (French, German, Spanish and Middle Dutch). Despite its medieval popularity, The Doctrine of the Hert has largely escaped the attention of scholars until recently. Yet it has much to offer regarding our understanding of late medieval female spirituality.
