The thirteen essays in this book, presented in honour of Dr A.V.C. (Carl) Schmidt, are designed to reflect the range of his interests. Dr Schmidt, who was a Fellow at Balliol College, Oxford from 1972 until his retirement in 2011, is best known for his comprehensive four-text edition of Piers Plowman, the fruit of a lifetime's work on that text. He has also made a major contribution to the study of Chaucer and the medieval English contemplatives, and these authors also find a place in this collection. The essays presented here are intended to build upon the legacy of Carl Schmidt's exemplary scholarship.
