Jac Leirner's *Double Blue Chain* is a sculptural work that exemplifies the Brazilian artist's signature practice of assembling accumulations of everyday, often discarded objects into minimalist yet conceptually rich forms. The piece likely features two interlinked chain-like structures rendered in blue, reflecting Leirner's longstanding interest in repetition, seriality, and the transformation of mundane materials into elegant compositions. Through this work, Leirner explores themes of connection, accumulation, and the poetic potential found within simple, repeating units.
