It was a confluence of influences - from Paul Cézanne and Henri Rousseau, to archaic and tribal art - that encouraged Picasso to lend his figures more structure and ultimately set him on the path towards Cubism, in which he deconstructed the conventions of perspective that had dominated painting since the Renaissance. These innovations would have far-reaching consequences for practically all of modern art, revolutionizing attitudes to the depiction of form in space.
