Non-Linear Models for Thinking and Writing on New Media Art History Gabriela Galati University of Plymouth Key words: non-linear model art history new media history hyperlink ambiguity Abstract: The ‘idea of the Theatre’ was fundamentally a structure of conceptual relationships rather than an actual building that Camillo understood as a spatial representation of chronology. Warburg’s ‘Mnemosyne Atlas’ project is centered on images: It is aimed at creating relations and bringing memories in rapport with each other. Both models share stunning and almost predictive similarities with the actual Web, where the possibility of accessing knowledge has an analogous structure even if the materiality of the support is different for obvious reasons. The interest in the concept of ambiguity in this regard lays in the freedom it could open for a potential lecture that at the same time allows the possibility of triggering new relations and creative associations, opening conceptual paths that have not yet been considered; the aperture and simultaneity of non-unilateral models for (creative) thought allows the reconstruction of the Theater, or the Atlas, not as a 3D illusion, but as the conceptual architecture or structure when thinking about the history of art, on the history and theory of new media, and on the transmission, conservation and archiving of new media works and of knowledge in general.
