In 1908, Boccioni met in Milan marinetti, an Italian poet: it was a determining meeting. The following year, on the 20th of February 1909, Marinetti published the Proclamation of the futuristic poetry.
On the 11th of February 1910, it was the turn of some Italian painters to publish
the Proclamation of the futuristic painters.
Carlo Carrà tells:
"To spread few days later to a thousand of specimens, this call to a bold and opened rebellion, under the grey sky of our country, made the effect of an electric discharge".

Boccioni becomes the theorist of this movement.
In 1914, he will publish futuristic Paintings, Sculptures and thus explains the goal of futuristic painting:
"While the impressionists do a painting to give a particular moment and subordinate the life of the painting to its resemblance with this moment, we synthesize every moment (time, place, form, color, tone) and thus build the painting".
His masterpiece, the Elasticity. It is the synthesis of the movements of a racehorse. We recognize the same elements of dynamism in his sculptures, which represent a great part of its work: Synthesis of the human dynamism, Development of a bottle in the space, single form of continuity in space. Mobilized in the declaration of war, Boccioni died in 1916 due to a fall from an horse.
