"For a number of years, Shimon Attie has created his own photographic palimpsests, projecting historical images onto public spaces and then photographing them, trying to bring out buried layers of memory. "I am trying to give visual form to history and memory which is latent in the architecture and landscape of the present, latent but not visible. . . . More than my therapeutic training, I think my temperament made me interested in revealing layers of a buried or repressed past." The projected image, Attie says, is a physical embodiment of the process of memory itself. "Like memory, the projection appears to have substance and materiality, but in fact it does not—it is only photons," he says. "It’s an illusion." The projections of historical photographs onto actual sites in the present have a ghostly, immaterial, ephemeral quality of fleeting memory."
