Every season, the systems that feed the mangrove creek of Baraltja (home of Burrut’tji, the Lightning Snake) bring in the new season freshwaters. One source is from the Dhalwaŋu clan estates of Gäṉgaṉ depicted by this diamond design. As it does Burrut’tji ‘tastes” the first freshwater coming down. At this the Lightning Snake at its residence stands on its tail and spits lightning into the storm. Incoming waters flood first the plains then the mangrove lined creeks that finally empty into the sea. Leaves of the mangroves fallen into the water bank up on the surface in fields of red, yellow and black known as Motu. The serpent has been depicted spitting lightning. This action shows communication between the different lightning snakes of different Yirritja clans located hundreds of miles away which is seen in the lightning. They are located to the East and south West and this is why the snakes indicate direction in a mirrored way. In ancestral times, Burrut’tji travelled underground to Gäṉgaṉ (homeland of the Dha`waŋu people) and other places far away from his home and into country belonging to other clans including the Maŋgalili. The spine of the snake is important as it was laid underwater as part of a fish trap made by ancestral Yirritja. It is the ancestral remains of this trap that cause a natural barrage across the tidal creek leading out of Baraltja that concentrates the flow from the plain banking up the motu (fallen mangrove leaves) at this site. The water rat is a colleague and food source of Mundukul. In mortuary ceremonies held for Yolŋu in the past, a hollow log was used to contain the bones of the deceased. Burrut’tji is closely associated with the hollow log in mortuary ceremonies. Burrut’tji and his home are most sacred aspects of the ceremony which would be conducted only by elder men. Women would not be able to enter the area of the ceremonial ground used to represent Burrut’tji’s home – the journey of the spirit of the deceased Maḏarrpa person begins from this site. In the less restricted sections of this story, both men and women dance the fish, birds, mangrove leaves, fish trap, dogs, tide lines and other elements and tell the same story through song and dance. In summary, the diamond based field which includes an elliptical shape is the muddied freshwater of the bottom Dhalwaŋu clan downstream from Gangan. The conception that this flows out through Baraltja (a small mangrove creek in a different watercouse) is actually technically possible at the time of Wet Season inundation of the floodplains behind the mangroves where an expanse of water up to 50km long can exist connecting the two. But the real connection being mapped is that between the Dhalwangu and their mother’s mothers- the Madarrpa. The artist said that Burrut’tji has a place at Gangan and this site mirrors the one at Baraltja, side by side.
