Abstract
The development of art history as an academic discipline was closely intertwined with photography.

Secondly, it describes four different strategies of coping with these differences between original works of art and their photography and with the absence of the works of art themselves in written and performed art history: descriptions of objects, claims of having seen the original, the attempt to produce lively photographs, and the slide performance
