Iranian sculptor, scholar, and collector Parviz Tanavoli presents a book about the hand-woven bags made by Iran?s tribal peoples. These practical objects are steeped in folkloric narratives and myths, each a unique expression of their makers. Mainly woven by women, the bags are used by shepherds to carry salt for their livestock while grazing. Not only are the traditional bags a reflection of the material culture of the tribes of the Iranian Plateau, they also signify the deep social significance salt has held since prehistoric times. Like bread, the concept of salt permeates Iranian culture both historically and today through many sayings, proverbs, rituals, and social interactions.
