Abstract
For Siqueiros, Mexican revolutionary mural painter, canvas and oils are the "outworn conventions of a dying bourgeois culture". Thus the topic of the work or the conventions in painting are less a symbol than the institutionalized way to paint a canvas on an easel. The painting by Pollock is a perfect representation of this revolution of "horizontal axis". To symbolically give up the bourgeois vertical axis of painting or the vertical way it will be hold up on the wall, the canvas is now displayed on the floor. The artist is above and he is the one staying vertical; implicitly, it is for me a gesture of the artists' domination over their work.
