Barrikadenwetter (barricade weather) is a term coined by the anarchist Mikhail Bakunin in the newspaper Dresdner Zeitung on May 3, 1849: it denotes the moment of transition in which a revolutionary subject emerges within collective action, and reifies itself as an obstruction that stands in the way of established order. Starting from a historical survey by the Arsenale Institute—a research group which has long been engaged in projects related to visual arts as well as the critical analysis of the politics of representation—the exhibition explores the construction, concept and iconography of the barricade, from its beginnings in the late Renaissance to present times, tracing its historical connections with the roots of the 20th century avant-garde.
