Changes in Degas' style correlated rather closely with this progressive loss of vision. His works in the 1870s were drawn quite precisely with facial detail, careful shading, and attention to the folding of ballet costumes and towels. As his visual acuity began to diminish in the 1880s and 1890s, he drew the same subjects, but the shading lines and details of the face, hair, and clothing became progressively less refined (Figure 2A, B, and C). One study13 showed that the spacing of his shading lines increased in proportion to his failing visual acuity over nearly 3 decades. After 1900, these effects were quite extreme and many pictures seem mere shadows of his customary style (eg, Figure 2C). Bodies were outlined irregularly, images were marred by strange blotches of color, and there was virtually no detailing of faces or clothing. Nothing in Degas' correspondence indicated that he was consciously trying to be more expressionistic or abstract; in fact, his pastels were drawn on larger and larger expanses of paper as he struggled to work. One critic wrote that “these sketches are the tragic witnesses of this battle of the artist against his infirmity.”14 One may reasonably ask whether Degas intended these images to appear to us the way they do and why he continued to work when the product seemed so out of line with his traditional style. Some answers may lie in the recognition of how these works appeared to him.
