Steinberg discusses about a shift in the picture plane from the “old Masters practice of using of devises to draw attention to the art. On how the conception of the picture is representing a world with a human posture. He talks about the works of Rauschenberg, Duchamp and Dubuffet, how they still hang them on wall. Richard Sierra’s text is about removing the piece from the site specific and talks about working outside the studio surround by Urbanism and Industry. He discusses using the knowledge, skills and capabilities of a mill, plant or fabricator making his work.  How the concept of site specific sculpture has nothing to do with opinion or belief. Similarity is that both authors talk about that there was a shift in their individual areas of focus during that time around the 1950s.
