Painting the phases of a riot

If we paint the phases of a riot, the crowd bustling with uplifted fists and the noisy onslaughts od cavalry are translated upon the canvas in sheaves of lines corresponding with all the conflicting forces, following the general laws of violence of the picture… …These force-lines must encircle and involve the spectator so that he will an a manner be forced to struggle himself with the persons in the picture.

Umberto Boccioni
