"Born in the Finger Lakes region of upstate New York in the mid-1800s, O-ism's beliefs included the notion of a female deity, of time going backwards, of spiritual transience, and a prohibition on figurative art."
Richard Selesnick and Nicholas Kahn's Circular River project (1998-99) is a fictive photodocumentary purporting to tell the story of a 1944 British "Royal Excavation Corps" expedition to Siberia in search of Peter Hesselbach, a downed German glider pilot.
In 1968, the Belgian artist Marcel Broodthaers created an installation in his house that he entitled the Musée de l'Art Moderne, Départment des Aigles, or Museum of Modern Art, Department of Eagles. This was a fictive entity in that the museum had neither a permanent building nor a collection; nonetheless, it was elaborated by Broodthaers in about a dozen further installations. Evidence of the museum's existence (apart from its title) ultimately encompassed specially created objects, films, and art reproductions as well as ephemera such as wall labels and signage.
