Epigraphs as thresholds (especially in the AP--the first epigraph of the AP is about thresholds--see chapter on arcades).
"Boredom is the threshold to great deeds. --Now, it would be important to know: What is the dialectical antithesis to boredom?" [D2, 7] (AP 105)
"Rather than pass the time, one must invite
it in. To pass the time (to kill time, expel
it): the gambler. Time spills from his every
pore. To store time as a battery stores
energy: the flâneur. Finally, the third type:
he who waits. He takes in the time and
renders it up in altered formthat of
expectation." (AP 107)
The 1999 English translation of The Arcades Project begins with the following epigraph:
"The waters are blue, the plants pink; the
evening is sweet to look on;
One goes for a walk; the grandes dames
go for a walk; behind them stroll the
petites dames.

--Nguyen Trong Hiep, Paris, 
capitale del al France: Receuil de 
vers (Hanoi, 1897), poem 25"
We begin with a quotation from a turn of the century Vietnamese writer. Bartolovich has the following theory to explain that:
See the following:
"In the real world of geopolitics and
hierarchies of nations, however, languages
(and nations) do not confront each other
as anything like equals. Paris was capital
of the nineteenth century in large part
because of France's imperial incursions,
whose effects are discreetly signaled in
Benjamin's choosing as an epigraph for the
1935 Exposé of his Arcades Project the
French words of a Vietnamese poet,
Nguyen Trong Hiep, one of the few non-
European voices in Benjamin's work. Paris
is intertwined, unquestionably, with Berlin
in Benjamin's account, but also, via
Nguyen, with Hanoi (and so on, through
all its various material relations with the
world). We must attend to the totality of
these relations, and the inequality of
peoples with respect to each other implied
in the world's actually existing form,
whether or not Benjamin explicitly
thematized these relations at any length.
They are, it seems to me, implicitly
important, even crucial, given the
anticapitalist reading practice he does
explicitly engage. In any case, some things,
he insisted, were better expressed by not
being said at all. As he puts it in Convolute
N of The Arcades Project: "method of
this project: literary montage. I needn't say
anything. Merely show. I shall purloin no
valuables, appropriate no ingenious
formulations. But the rags, the 
refusethese I will not inventory but allow
in the only way possible, to come into their
own: by making use of them" (460). While
in his texts Asian, South American, and
African images can certainly be read as
playing the role of displacing, or standing
in for, the actual oppressive material
entanglements of Europe and the "rest of
the world," as in other primitivist 
appropriations, we can also see how his
reticence might be directed against
obfuscation since the form of Benjamin's
text, and the reading practice it demands,
always points us toward the unsaid. 38
The unsaid in his case differs, then, from
the "sanctioned ignorance" for which
Gayatri Chakravorty Spivak rightly took
to task Foucault's writing, in which the
colonial situation seems everywhere
evoked but rarely named as 
suchcertainly not as the fact of
European everyday life that it has been
from the sixteenth century to the present
(291). The difference in the case of
Berliner Chronik is that Benjamin's
compiling out of the mass of evidence
before us the ordinarily overlooked,
misread, and despised was intended to
bring capital's invisibilities into focus. In
this respect, although his texts don't
announce an anti-imperial agenda as such,
they can still be understood as providing
an anti-imperialist reading practiceor at
least demanding such a reading practice
from inhabitants of an imperialist world to
which his texts are offered as counterpoint.
("Figuring the (in)visible in An Imperial
Weltstadt: The Case of Benjamin's Moor"
Crystal Bartolovich): [available on Project
Muse]
Bartolovich begins her discussion with a reference to Yinka Shonibare who reupholstered Victorian interiors with African prints.
We begin with a demonstration of the pervasive nature of Imperial Parisand the implicit threshold state of a political entity intent on extending its boundaries. From the first page Benjamin highlights Paris' nodal quality, its position as a place of chance encounters, of collisions between cultures, as a passage between worlds in itself. Paris in this sense functions as a rhizome, extending, territorializing, advancing itself as a nomadic "war machine" that knows no boundaries (1000 P "Nomadology"):
"Empire is the style of revolutionary terrorism, for which the state is an end in itself." (AP 4).
We move on to Section I, "Fourier, or the Arcades" which bears the same epigraph that Benjamin later used for Convolute A (See THE ARCADES PROJECT). It is a description of a threshold:
"Most of the Paris arcades come into
being in the decade and a half after 1822.
The first condition for their emergence is
the boom in the textile trade. Magazins de
nouveautés, the first establishments to
keep large stocks of merchandise on the
premises, make their appearance. They
are the forerunners of the department
stores . . . The arcades are a center of
commerce in luxury items. In fitting them
out, art enters the service of the merchant."
(AP 3)
So, once stores started keeping large stocks, inventories, the manner in which shopkeepers collected the items brought the necessity of an artistic sensibility to the merchant's professionmaking "industry . . . rival of the arts" (AP 3). Assembling, displaying, collecting the items for sale, became an art form which need not to disguise its role in the present economy. By arranging stock items in an aesthetically pleasing way, shopkeepers put to work the necessity of storage, creating with excessive stock, "worlds in miniature" through which passersby could move, distracted by messages implied through juxtaposition, diverted hither and thither by their most intimate desires. The store becomes an external manifestation of the psychea dream world through which city inhabitants might wander "aimlessly" lest something unthought of catch a thread (Whitman's "filament") take holdan anchor seat itselfexposing novelty. Thus the flâneur makes his way through the labyrinth as a large net, extending his locus as a spider who spins her web in order to catch whatever chance may bring along.
