11. We shall sing the great masses shaken with work, pleasure, or rebellion: we shall sing the multicolored and polyphonic tidal waves of revolution in the modern metropolis; shall sing the vibrating nocturnal fervor of factories and shipyards burning under violent electrical moons; bloated railroad stations that devour smoking serpents; factories hanging from the sky by the twisting threads of spiraling smoke; bridges like gigantic gymnasts who span rivers, flashing at the sun with the gleam of a knife; adventurous steamships that scent the horizon, locomotives with their swollen chest, pawing the tracks like massive steel horses bridled with pipes, and the oscillating flight of airplanes, whose propeller flaps at the wind like a flag and seems to applaud like a delirious crowd.
Filippo Tommaso Marinetti
