 The humans born of the two sisters are the ancestors of the Dua clans, the animals the sisters created are the totem animals of those clans, and the places the sisters visited are the clan shrines.The mythology was staged in early contact times by the Dua during several days of dancing, singing, and the manipulation of sacred emblems, on a stage of man-made holes and earth sculpture.The other moiety of the region, the Yirritja (or Yiritja), also participated in the dramatisation of the Djanggawul myth, although some of the rites were accessible only to initiated Dua males.
