..into this chaos [after the Bolshevik' revolution] came suprematism extolling the square [referring to the Squares of Malevich] as the very source of all creative expression, and then came communism and extolled work as the true source of man's heartbeat.

And amid the thunderous roar of a world in collision WE, ON THE LAST STAGE OF THE PATH TO SUPREMATISM BLASTED ASIDE THE OLD WORK OF ART LIKE A BEING OF FLESH AND BLOOD AND TURNED IT INTO A WORLD FLOATING IN SPACE. WE CARRIED BOTH PICTURE AND VIEWER OUT BEYOND THE CONFINES OF THIS SPHERE AND IN ORDER TO COMPREHEND IT FULLY THE VIEWER MUST CIRCLE LIKE A PLANET ROUND THE PICTURE WHICH REMAINS IMMOBILE IN THE CENTER.

The same fate must also overtake the architecture of cubist contre-relief.. .By taking these elements FROM THEM for itself it wants to become equally entitled to take its place alongside them as a new creation. The reference is to the narrow technical discoveries for example the submarine, the aeroplane, the motors and dynamos of every kind of motive power in each part of a battle-ship. Contre-relief is instinctively aware of their legitimate origin their economy of form and their realism of treatment.
