"Once, in 1946, while still an adolescent, I was to sign my name on the other side of the sky during a fantastic ‘realistico-imaginary’ journey. That day, as I lay stretched upon the beach of Nice, I began to feel hatred for birds which flew back and forth across my blue sky, cloudless sky, because they tried to bore holes in my greatest and most beautiful work. Birds must be eliminated."
-Yves Klein, The Chelsea Hotel Manifesto, 1961
"At my direction, the flesh itself applied the color to the surface,and with perfect exactness. I could continue to maintain a precise distance from my creation and still dominate its execution. In this way, I stayed clean. I no longer dirtied myself with color, not even the tips of my fingers.The work finished itself there in front of me […] And I could salute its birth into the tangible world in a fitting manner, in evening dress."
-Yves Klein, 1960 Monotone-Silence Symphony
