Kunmanggur is the Rainbow Serpent of the Murinbata of Port Keats (Wadeye) in the Northern Territory, and one of the three principal beings of their religion recorded by W. E. H. Stanner alongside Mutjingga and Kukpi. In the beginning he was a beneficent culture-hero, a man of super-human size and power who made the first boy and girl, opened the deep fresh-water pools, and was the reputed source of spirit-children, rain, fish, flying-foxes and the general increase of nature; the brightest, blood-red band of the rainbow was identified with him. The central myth, which Stanner treated as a 'riteless myth', tells how his son Tjinimin the bat violated his daughters and then mortally speared him; gravely wounded, Kunmanggur made his way to the sea, gathering up the fire of the land, and sank beneath the water to become the Rainbow Serpent. Stanner remarked of the tale that 'paradox and antinomy were the marrow in the story's bones'. The myth was further analysed in structural terms by Kenneth Maddock.
