It is a unique story, that of byssus; threads produced by the largest mollusc in the Mediterranean, and Chiara Vigo, Sardinian from Sant’Antioco (Italy) and last master in the world able to weave them. Byssus is a precious thread that can neither be bought nor sold and, as the Bible tells us, has been worn by high priests and kings since ancient times. An artistic biography that reads like a fairy tale is actually the story of a past that has miraculously remained intact.
