The essay discusses a small selection of unpublished letters signed by Louise Michel and addressed to Panagiotis Argyriades dated from 1885 to 1901. I attempt to historically contextualize and critically examine this correspondence with a view to foregrounding the unknown relations between the two revolutionaries. The essay also selectively cites and describes material drawn from the case file of Argyriades during his surveillance by the Paris Police. I briefly summarize the multiplicity and traceability of the mediation by the state apparatus, as well as the way in which the two archival records share common ground; given that the Louise Michel letters shed light on the police record as a derivative (or even perhaps a product) of power relations, they allow the historian to contrapuntally read the archive.
