Marcel Duchamp’s older artist brothers Jacques Villon and Raymond Duchamp Villon chose to rename themselves after the cheeky mediaeval poet Francois Villon. They were key in the formation of Marcel’s ideas, both in his agreement with them and reaction to their actions.

It discusses several readymades and explains Duchamp’s use of French linguistic nuance clearly. Above all with his humor in mind.
