 The "Indian Act" banned manifestations of the Sun Dance, the Potlatch, and works of art depicting them.It was not until the 1950s and 1960s that indigenous artists such as Mungo Martin, Bill Reid and Norval Morrisseau began to publicly renew and re-invent indigenous art traditions.Currently there are indigenous artists practising in all media in Canada and two indigenous artists, Edward Poitras and Rebecca Belmore, have represented Canada at the Venice Biennale in 1995 and 2005 respectively.
