Gesture in art can be expressed in many ways. Edgar Degas sketches figures in different poses to help determine how best to portray a gesture. He also creates angles can help guide the viewer’s focus to different elements of the painting. Gustave Caillebotte foreshortens forms to create the illusion of depth on a flat picture plane. Degas exaggerates his subject’s facial expressions to accentuate gesture. Mary Cassatt matches a gesture to the atmosphere in herwork to produce a sense of unity, bringing harmony to the painting.
