Present rooms become historicist simulacra when quoted and emptied of concrete life.

Evidence

In fact, such rooms are preserved as in a museum: untouched, intact, yet now somehow “quoted” and without the slightest modification emptied, as in the transformation of something into an image of itself, of its concrete life, like a Disneyland preserved and perpetuated by Martians for their own delectation and historical research. … Yet it is a present reality that has been transformed into a simulacrum by the process of wrapping, or quotation, and has thereby become not historical but historicist — an allusion to a present out of real history which might just as well be a past removed from real history. — Fredric Jameson, Postmodernism, or, The Cultural Logic…, 308

Categorization

• DEFINE: Distinguishes ‘historical’ from ‘historicist’ — exactly the parody/pastiche and periodization work the reader needs: the quoted room is an allusion, not lived history.
• XREF: The ‘transformation into an image of itself’ traces to Debord’s spectacle and echoes the ‘waning of affect’ discussion later in the book; the critic’s map of this ties to Jameson’s theory of postmodern pastiche.
• ADDENDUM: The ‘empty room as image of itself’ parallels the ‘Grafting & Growth’ article’s graft-as-quotation idea — preservation that strips the object’s living function, like the bark-cloth tree kept only as image.
