Véronique Plesch was invited to participate at the workshop “Écritures exposées : la fabrique des espaces ‘publics'” (Exposed Writings: The Making of “Public” Space) organized by the École des Hautes Etudes en Sciences Sociales, Paris (School of Advanced Studies in the Social Sciences). The meeting took place Friday 27 November and Plesch provided a response to a paper on 16th-18th-century graffiti left by religious prisoners, along with a discussion of the aims of the workshop, focussing on the concepts at stake and in particular, issues concerning writing and space.
