A few hours later: Since posting this, it's struck me that, of course, Walter Benjamin focuses on dust in the Arcades Project. This from Teresa Stoppani, 2007, 'Dust projects', Journal of Architecture, 12/5, 543-557:
In Benjamin’s Passagen-Werk dust is associated with ideas of greyness, obsolescence and boredom. Dust blankets Paris like a heavy grey coat. It nests in the arcades and in the bourgeois interiors, materialising oblivion, stillness and decay. And yet, slow or fast, in both interiors and exteriors, dust measures the uncontrollable, penetrating that which is apparently ordered, organised, systematised. [my italics]
And dust texts? Dust language even?
