This book seeks to fill an important gap in our knowledge of painting in fifteenth-century France. Focusing on the work of ?the Master of Morgan 453, ? an accomplished, if unnamed, manuscript illuminator, Clark identifies, compares, and analyzes all extant books that can be attributed to the painter and reconstructs his career on the basis of a wide range of liturgical as well as art-historical criteria. In examining collaborations and workshop practices involving many different illuminators who hailed not only from Northern France but also from the Netherlands, Clark's work also sheds light on complex artistic interchanges between France, Flanders, and England at a time of profound political change. The survey of the career of the Morgan 453 Master and his intense artistic milieu is complemented by a comprehensive catalogue of manuscripts and a checklist of Parisian illuminators and manuscripts, ca. 1420-1450, as well as liturgical appendices and an associated website
