Naum Gabo

 “The real stuff of Gabo’s art is not his physical materials, but his perception of space, time and movement. In the calmness at the ‘still centre’ of even his smallest works, we sense the vastness of space, the enormity of his conception, time as continuous growth.” In fact, the element of movement in Gabo’s sculpture is connected to a strong rhythm, more implicit and deeper than the chaotic patterns of life itself. The exactness of form leads the viewer to imagine journeying into, through, over and around his sculptures.
