Art History is centrally concerned with a vast array of three-dimensional objects, such as sculptures, and spaces, such as architecture. Digital technologies allow the creation of virtual spaces, which in turn allow us to simulate and compare aspects of a visual culture's three-dimensional timespace that cannot be communicated as a single, still image. The third issue, thus, focusses on the third dimension in Art History, and the digital realm that continues to mediate and transform it.

Liska Surkemper is a Ph.D. candidate for architectural and cultural theory at the Technical University Munich. She conducts research on visual epistemology and the interrelationship of pictures, architecture and economy. From 2010 to 2014, she was a researcher and lecturer at the Department of Art Research and Media Philosophy at the University of Arts and Design Karlsruhe. She was also coordinator for the DH project "Memory of Scientific Knowledge and Artistic Approaches", which was supported by the German Federal Ministry of Education and Research (BMBF). Together with computer scientists, designers and arts scholars she helped develop the web application "Presenter": a tool for visualizing, sharing and archiving scientific and artistic knowledge.
