Michelangelo Pistoletto's *Gemelle (Mirror Triptych)* is a complete set of three screenprints rendered on mirrored acrylic, a medium central to the Italian Arte Povera artist's celebrated practice of dissolving the boundary between the artwork and the viewer's reality. The reflective surfaces incorporate photographic imagery of two identical female figures, whose twin presence is further multiplied and fragmented by the mirror itself, drawing the surrounding environment and the viewer into the composition. This work exemplifies Pistoletto's enduring investigation into identity, duality, and the participatory nature of perception.
