The Rainbow Serpent or Rainbow Snake is a common deity often seen as a creator god, known by numerous names in different Australian Aboriginal languages, and a common motif in the art and religion of Aboriginal Australia. Not all of the myths of the ancestral being link a rainbow with the snake and not all describe the being as a snake, but there is usually a link with water or rain. Some scholars have suggested that the link between the two suggests the cycle of the seasons, for example blue (winter), red (summer), yellow (spring) and orange (autumn), and the importance of water in human life. When the rainbow is seen in the sky, it is said to be the Rainbow Serpent moving from one waterhole to another and the divine concept explained why some waterholes never dried up when drought struck.
