Jennifer Raab, assistant professor, department of the history of art, Yale University. What does it mean to see a work of art “in detail”? Speaking at the inaugural John Wilmerding Symposium on American Art, held on October 22, 2016, at the National Gallery of Art, Jennifer Raab considers broader questions of detail, vision, and knowledge in 19th-century America by looking at a few of Frederic Church’s most famous landscape paintings. The John Wilmerding Symposium on American Art is made possible by a generous grant from The Walton Family Foundation.
