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).
You may know Marcel Duchamp, but have you encountered his artistic alias Rrose Sélavy? Duchamp attributed several of his works to Rrose, including the pun-filled Anemic Cinema. Even the name of his alter ego was a play on words since Rrose Sélavy can.
