The Warrangau corroboree is performed to the rhythm of clapping boomerangs (foreground) by dancers decorated with birds' down, stuck on with blood from gashes in the arm. Wooden crosspiece on headgear, centre, represents buffalo horn (University of Sydney Photograph) style with high knee action stamping of great virility. At other times there was a melting grace of cat-like softness about the dance as if it were a lament of deep-welling sorrow. In another ceremony, the men's bodies trembled in such intensity that the 12 foot leafy poles attached to their legs shivered to the very tips and swayed out over the heads of the seated crowd. The women's dances, as they shuffled in place were softly quiet. Their eyes were shyly cast down as their heads moved poised and gracious to the right, then to the left, their arm movements were sometimes a relaxed swinging to and fro, or they could be controlled, ineffably graceful like a ballet dancer's studied movements. In non-sacred dance, the men showed not Mosik and Bill of the Millingimbi people lead a corroboree. These two men have been numbered among the world's greatest dancers. (Australian Official Photo)
