Modeled on the Venice Biennale, the Bienal de São Paulo, founded in 1951, has grown into one of the world’s most important arts events. Many of the participants are working artists who have been nominated by their home country. In addition, a guest curator chooses a theme and invites his or her own favorites. At its best, the Bienal offers the world a chance to view mindbending contemporary art. Certainly it cannot fail to be impressive for its sheer size and diversity.
