Marcel Duchamp was an artist who devoted a long time to creating one summary work. Three years of studies and plans, followed by eight years of labor and reflection, were required for his much-celebrated The Large Glass
, also known as The Bride Stripped Bare by her Bachelors, Even
. In the end the Glass
, begun in 1915, was left "definitively unfinished" in 1923.
