Those things acquire a new, specifically artistic life in the vibrations released by the proximity of such varied images, such various references. The objects remain recognizable, but they have been subjected to an invisible transformation. Objects of one order become objects of another; objects of cultural manipulation become objects of artistic signification (meaning-making).
The phrase "still life" also explains the arrangement of those objects in the paintings. In fact, I take the "still life" concept to one particular extreme, tying the objects to one another in the necessary manner but not to any "realistic" grounding (for instance, they are not fixed to a particular horizontal or vertical plane). Separate objects or clusters are often not only discrete entities, but separate spaces, individuated by being rendered in a shifted perspective applied to each one separately. As a result, while resonating with the other elements of the painting, they may exist in their own space, and thus in their own time.
