By choosing this rough jute fabric, Burri opened up another path, because the image of the sack – a container that has vanished from our visual horizon – is interwoven with distant memories: contrition and repentance (the “sackcloth” of the Middle Ages), but also the toil of manual labour: lifting, carrying, filling and emptying. In the austere fabrics of Nero con punti rossi we find other things as well.
