The Ancrene Wisse, a guide for female recluses written in the West Midlands in the early thirteenth century, and the closely related religious works of the `Katherine Group', offer a vivid insight into the religious life of the time, and their rich and varied prose style blends Latin andnative English stylistic traditions with remarkable skill and assurance. The difficulty of their language, however, has made them largely inaccessible except to experts in Middle English, and this edition is designed to introduce them to a wider audience, including undergraduates with limitedexperience of Middle English and specialists in other disciplines, particularly history, theology, and women's studies. It provides a representative selection (the last two parts of Ancrene Wisse, and three complete works from the Katherine Group, Hali Meithhad, Sawles Warde, and Seinte Margarete)in new and readable critical texts, with a general introduction, notes, a select glossary, and interleaved translations.
