Palast der Republik, by the photographer Christoph Rokitta, is an independent photobook published in 2013 in Berlin. In the photobook different semiotic resources are coupled in order to iconically model the demolition of the homonymous building in Berlin. In opposition to the trivial notion of icon as sign that stands for its object in a relation of similarity, we are going to analyze the photobook as an icon whose main feature is the possibility of discovering information about its object through its manipulation. This specific feature is called operational criterion for iconicity, and it stresses the inherent quality of icons of revealing information available through their manipulation and observation.  Our aim is to describe and analyze the relations between semiotic resources in this photobook, by exploring the operational criterion of iconicity, and models as epistemic artifacts. We are interested in how couplings between semiotic resources in the photobook can iconically model a spatio-temporal process.
