A series of photographs of radioactive minerals created by the artist in the radiation-proof, thickly-walled basement of the Mineralogical and Geological Museum at Harvard University. These minerals resemble asteroids, maps, or totemic shards— uncanny objects radiating lives of their own, of ambiguous scale. Photographed in darkness, the fluorescing uranium emits radiation and light, oscillating between visible and invisible threat, and allude to early photography’s pre-occupation with rayograms, contact and exposure. Several of the specimens that appear in the prints include psuedomorphs, where one mineral takes on the outward form of another, its appearance and dimensions remaining constant, but the mineral entirely replaced— thus extending Siegel’s concerns with doubling, mimicry, cultural property and authenticity.
