Edgar Degas is best known as a painter and chronicler of the ballet, yet an exhibition at the Museum of Modern Art of his work as a printmaker reveals the true extent of his restless experimentation. In the mid-1870s, Degas was introduced to the monotype process — drawing in ink on a metal plate that was then run through a press, typically resulting in a single print. Captivated by the monotype’s potential, he immersed in the technique with enormous enthusiasm, taking the medium to radical ends. The exhibition includes approximately 120 rarely seen monotypes — along with some 60 related paintings, drawings, pastels, sketchbooks, and prints — that show Degas at his most modern.
