This publication celebrates the Yale University Art Gallery’s expansive holdings of paintings, etchings, drawings, and bronze and wax sculptures by the French master Edgar Degas (1834–1917) and reiterates and expands upon what continually intrigues viewers about him: that he was an unrelenting artist, working in oil, pastel, charcoal, sculpture, and print media, who critically visited and revisited problems of form and process throughout his long career. Portraying such modern subjects as ballet dancers, bathers, and horse races, Degas soon graduated from skilled copyist to influential innovator. “Degas defined the edges of the modern,” writes Jennifer R. Gross in the introduction to the catalogue, “because he worked at the fringe of his society and worked away at the limits of the artificiality and truth telling of his art.”
