Professor of Art Véronique Plesch was invited to participate in 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 Nov. 27, 2020, and Plesch provided a response to a paper on 16th-18th-century graffiti left by religious prisoners and contributed to a discussion of the aims of the workshop, focusing on the concepts at stake and, in particular, issues concerning writing and space.
