NEW YORK — Aboriginal art — a term typically used to describe works made by the indigenous people of Australia — takes several forms, all intriguing. They range from body paint and bark paintings to rock art; ochre paintings using organic pigments; textiles; wood carvings; and paintings on canvas, linen or wood. Paintings, in particular, have become one of the most desirable forms of Aboriginal art to collect and are widely represented in museums and fine collections around the world.
