The snowball principle of art; art as a conglomerate of works and people that refer more or less explicitly to one another; every particle absorbed into the art conglomerate becomes connected with every other particle, and all remain stored therein, for ever. Hidden behind the intentionally fusty title An introduction to the history of art is not a cross-section through what has been and gone, but a topical exhibition concept aimed at examining the modern “art on art”, i.e. the relations between the individual components of the art conglomerate. Sixteen international artists showcase works – films, installations and photographs – that deal with the representation of known examples from art history. The subliminal connections, the allusions, are made explicit, and the use of specific works of art from different ages, largely un-manipulated, paves the way for a discussion of entirely new issues. One area of focus, highlighted also in the texts by the three authors, looks at issues such as the photography of art and photography as art.
