Since the Gothic, European sculpture had become overgrown with moss, weeds – all sorts of surface excrescences which completely concealed shape. It has been Brancusi's special mission to get rid of this overgrowth, and make us once more shape-conscious. To do this he has had to concentrate on very simple direct shapes, to keep his sculpture, as it were, one-cylindered, to refine and polish a single shape to a degree almost too precious.. ..it may now be no longer necessary to close down and restrict sculpture to the single form unit. We can now begin to open out. To relate and combine together several forms of varied sizes, sections, and directions into one organic whole.
