De papillons de nuit et de l’échelle de Muybridge / Of Moths and Muybridge’s Scale by Yann Annicchiarico is the second publication in the collection from the Contemporary Art and Historical Temporalities research unit. It is part of a project publishing thinking by contemporary artists. The thinking, developed through visual and sound forms, gestures, and as through dialogue and dialectical exposition, is presented in a distinctive format, with a layout designed by graphic designer Rémi Forte, developed by Juliette Flécheux and set out in a clear and flexible framework. Written language is one element of the collection project. But it remains partial, to be grasped along with the essential elements that complete it: the artworks, accompanied by documentation of exhibitions, archives, and other approaches of thought that the authors develop progressively with the research unit publications.
