Why is r. mutt's (duchamp's) fountain considered so important in art history? do you believe it is art? why or why not? will mark the !

From Andy Warhol to Joseph Beuys to Tracey Emin, this urinal inspired artists to reconsider the traditional artwork. Instead of paintings and sculptures, art was suddenly Brillo boxes, an unmade bed, or a light-bulb plugged into a lemon:ordinary objects, some readymade, removed from their original contexts and placed on display in art galleries. This is part of the reason the Fountain was voted the most important in the 20th Century. As for if I believe if it is art, it can be considered art and it can't, it really just depends on how you look at it. It can be considered urinal art because he made a use out of a already existing object. So I would consider it art but others may not. Hope this helped.
