Could one say of Seurat that his real detonators were his drawings? If Fénéon was a pointillist in his "novels in three lines," Seurat was a revolutionary in his drawings and paintings. Contributors to the MoMA catalog credit Seurat with, among other achievements, inspiring Van Gogh's broken brush strokes; showing the way toward abstract art; anticipating many of the effects of photography; and predicting the pixels of computers. But always with Seurat, as in the barbed-wire enclosure for this mysteriously veiled cat-woman, there is something that eludes us. As British abstract artist Bridget Riley remarks in a fine tribute in the MoMA catalog, Seurat adopted rational and scientific methods like a "protective shield" and presented us instead with "the mysterious." "Even today I feel a thrill," Riley writes, "when I read Félix Fénéon's first essay on Seurat, which ends: 'Let the hand be numb, but let the eye be agile, perspicacious, cunning.' "
