I first encountered John Baldessari’s unrealized proposal for Information in Elena Filipovic’s book The Apparently Marginal Activities of Marcel Duchamp while researching Étant donnés. Known for his transformation from painter to proto-conceptual artist, before eventually appearing to abandon artmaking all together, Duchamp spent the last twenty years of his life secretly crafting Étant donnés: 1° la chute d'eau / 2° le gaz d'éclairage (1946-1966), a life-size diorama, inside an apartment accessible through the bathroom of his Greenwich Village studio. The work consists of two peepholes in an old wooden door ––one for each eye––which reveal a woman lying naked in a thicket of branches, legs splayed, holding a flickering lantern in her left hand. A waterfall sparkles as it cascades over mountains in the distance. Her head is hidden from view, and the single forced perspective of the peephole prevents the voyeur from looking at anything else.
