You take in a painting in one glance, but you read a text over time; film in that sense is closer to text than painting, and the filmic term "montage" would be better for what happens when a text makes use of disparate, found, randomly combined elements. The only true "collage" effects in literature, i.e. the presentation in the same moment of perception of disparate materials would be certain "simultaneities," such as Dada and Merz and other, later sound-poets presented. (Landow 1999, p. 166.)
