Back in Paris after World War I, Duchamp experimented with machines that produced optical effects, work he had begun in New York. When this machine is set in motion, the circles appear to pulsate toward the viewer. The copper ring around the dome’s circumference is engraved with French words chosen for the way their sounds echo one another: Rrose Selavy et moi esquivons les ecchymoses des esquimaux aux mots exquis (Rrose Selavy and I dodge the Eskimos’s bruises with exquisite words).
