Surrealism’s models would be pornography. The things that happen in the collages, the things that are convulsively suspended in them like the tense lines of lasciviousness around a mouth, are the changes that occur in a pornographic image at the moment when the voyeur achieves gratification.
— Adorno, “Looking back on Surrealism” (in Noten zur Literatur I, 1956). Surrealist images mimic how pornographic images change the viewer in ways that change the appearance of the image.
