The theme consistent with most Australian tribes is that the Rainbow Serpent is the creator of the world and all beings. During the dry season, the Rainbow Serpent retreats to deep waterholes. Another common theme among all aboriginal tribes is that the Rainbow Serpent has no gender. And while the Rainbow Serpent can give fertility by creating rain, it can also let loose blindness and disease. "The Aboriginal Rainbow is humanity, because it causes the 'energy' and the 'breath' that gives people life."
