Outsider, queer and Indigenous artists are getting an overdue platform at the 60th Venice Biennale contemporary art exhibition that opened Saturday, curated for the first time by a Latin American. Brazilian curator Adriano Pedrosa’s main show, which accompanies 88 national pavilions for the seven-month run, is strong on figurative painting, with fewer installations than recent editions. A preponderance of artists are from the Global South, long overlooked by the mainstream art world circuits. Many are dead. Frida Kahlo, for example, is making her first appearance at the Venice Biennale. Her 1949 painting “Diego and I” hangs alongside one by her husband and fellow artist, Diego Rivera.
