“Art has always been employed by the different social classes who hold the balance of power as one instrument of domination — hence, as a political Instrument. One can analyze epoch after epoch–from the stone age to our own day–and see that there is no form of art which does not also play an essential political role . . . What is it then that we really need?… An art with revolution as its subject: because the principal interest in the worker’s life has to be touched first.”

–Diego Rivera, 1929
