At the heart of Chiara Dynys’s show “Aurora” was a work evoking a large piece of stage machinery, also titled Aurora, 2019: a sequence of rectangular frames in lacquered Plexiglas, brightly colored and with reflective inserts, nested one inside another so as to form a kind of telescope. In the deepest recesses of these multiple frames, a video showed a sequence of rooms, one inside another, in a similarly intense color scheme. (This video in fact documented an earlier installation by the artist.) The rest of the show consisted mainly of a group of glass boxes with mirrored surfaces at the back.
