This volume honors Maryan W. Ainsworth, curator emerita at The Metropolitan Museum of Art and former adjunct professor at Barnard College, whose work as a scholar, curator, and teacher has profoundly impacted the study of early northern European painting. Contributions by leading specialists from museums and academia, including former interns and fellows, reflect Ainsworth?s emphasis on the centrality of the object and on the interdisciplinary methods of technical art history, while also paying homage to the variety of Ainsworth?s research interests as a whole. The essays explore topics such as the working methods of individual artists, workshop practice, artistic collaboration, and patronage across a range of media?mainly painting, but also manuscript illumination, drawing, tapestry, sculpture, and stained glass.
