Youssouf Dara – a Dogon sculptor, the author of the Bródno toguna. Art plays an important role in the Dogon society: the people believe that with the artists’ magical skills, the Universe is kept alive. Once every sixty years, Sigui is organized – this is an eight-year long ceremony supposed to “renew the Cosmos”. The central figure in the ceremony is a few meters tall wooden structure called Mother of Masks. For each ceremony a new figure is produced by a tribal sculptor.
