Through his representation of modern subjects such as ballet dancers and race horses, his constant questioning of traditional artistic practices, and his vital engagement with Parisian society, Edgar Degas (1834-1917) helped to define the beginnings of modernism in visual culture at the end of the 19th century. This manual presents scholarship on works by Degas in the collection of the Yale University Art Gallery and provides in-depth discussion of works of art in every medium explored by this innovative artist. Extended entries by scholars such as Richard Kendall and Edgar Munhall provide a review of the artist's working methods. The volume also introduces several important pieces by Degas that have rarely been available for view by the public, including a notable wax figure and several unique prints and works on paper.
