This book, produced on the occasion of an exhibition of the same name at Kunstbibliothek, Staaliche Museen zu Berlin in 2003, includes nearly three dozen images of diagrams made by George Maciunas, a central organizer and participant of Fluxus, during the period 1953–1973. The reproductions are accompanied by a text by Astrit Schmidt-Burkhardt that provides insight into Maciunas’s graphic sensibility and preoccupation with developing schematic drawings as a means of historicizing and contextualizing the collective’s art practices. The study elucidates how, through charts, maps, and graphs, Fluxus (the name derives from the Latin fluere: to flow) could be made intelligible to a diverse art public.
