World Expositions as Time Machines: Two Views of the Visual Construction of Time between Anthropology and Futurama

International expositions as representative cultural phenomena which contributed to shape world history in the modern and contemporary age are currently approached from combined spatial points of view (in a geographical, material, and cultural sense). It is argued here that they may be better studied, and understood in the classroom, by also taking into account their temporal and historical dimensions. The symbolic and discursive structure and modules of exhibition-style events such as the "Great Expositions" during the nineteenth and twentieth centuries, particularly the living human expositions, have in fact been organized along temporal and historical coordinates as well as spatial ones. The following two sections will explain the functioning of expos as "time-machines," putting forward a temporal perspective and analytical dimension that can contribute to the advancement and teaching of World History in an innovative way, also beyond the specific study and teaching object of world expos and fairs – which nonetheless remain among the most significant and fascinating phenomena of historical and historiographical globalization.
