Balla, he advanced Dynamic Futurism.... drawing closer, not to the human body but to the machine, as contemporary muscles of a man of today... The actual structure of each of Balla's works tells us that the dynamic power sensed by the artist is incomparable greater than the actual bodies of the machines, and the content of each machine is only a small part of this dynamic power, since each machine is a mere unit from the sum total of the forces of contemporary life.
