If City of Men takes citation to a provocative extreme, audaciously rewriting Whitman in his own words (Whitman was of course continually rewriting himself, for example in his ongoing revisions to Leaves of Grass), the citational gesture and its allegorical structure are also crucial to reading Unbound as a poetics and a historiography of AIDS. In Shurin’s formulation of his project in “Inscribing AIDS: A Reflexive Poetics” (1995), he proposes to
estrange and reconstitute Whitman’s Civil War vocabulary, pushing images of battle and comradely witness to a newly disoriented wailing point. In “Human Immune” , the speaking subject inhabits experience from simultaneous locations as if all persons of voice (first, second, and third) are equally at risk. The poem proceeds formally via an epidemiological model: each “stanza” inexorably increases in length by one line, an expanding vortex. Hell is round, the motif…may bear Dante’s centripetal impasse, but also dimensionalizes AIDS from the personal to the historical: the curve one rounds is also around one, surrounding, a world. For the gay community, this circumnavigate descent can be read as the process of history itself disappearing. 
In these terms, the history summoned in the culling and grafting, the estranging and reconstituting of citation is itself in the process of disappearing, prematurely, perhaps irrevocably. “Inscribing AIDS” thus recalls the threat to historiography identified in Walter Benjamin’s fifth thesis On the Concept of History: “The past can be seized only as an image which flashes up at the instant when it can be recognized and is never seen again…. For every image of the past that is not recognized by the present as one of its own concerns threatens to disappear irretrievably.” If the witness who reads the process of history itself disappearing is haunted by images of the past (and ghosts abound in Unbound), the text of his testimony is likewise haunted by prior texts that are themselves commemorated even as they are enlisted in a work of commemoration.
