Constantin Brâncuși
Fish
Paris 1930
On view
MoMA, Floor 5, 500
This sculpture is the last of the seven Fish Brancusi created, and the largest. It attests to the artist's deep interest in movement; not only does its heavy body, made of flecked blue-gray marble, evoke aquatic motion, it rests on a pivot that once allowed the work to spin. Even when still, the work changes as one moves around it. Broad and horizontal, the marble transforms into an attenuated sliver from particular points of view.
