Long ago, two spirit men called Djirrawit and Nyäluŋ made a fish trap (dhawurr) in the Gurriyalayala River at Waṉḏawuy. The
fish trap was made of upright posts forked at the top with a long crosspiece siƫng in the forks. The space between was filled in
with more upright sticks (dharpa) interwoven with horizontal sticks.

Then Djirrawit and Nyäluŋ cut pieces of bark from the dhaŋgi tree, pounded them to release the poison, and threw them into
the river. The poison in the bark turned the water black and stunned the caƞish (gaṉŋal).

To collect all the stunned fish they used their fishing spears (gara) and double-sided triangular fishing nets (ganybu) made of
bush string (raki’). Djirrawit and Nyäluŋ got the idea for the special shape of these nets from watching pelicans (galumay)
catching fish in their big bills.

Yolŋu people learned from the two spirit men how to catch fish this way, and still do sometimes when there is a big gathering
of people needing much food.

The squared background design called gapu (meaning water) which is used in paintings of this story is a special clan design
belonging to the Djapu clan from Waṉḏawuy and represents that country (wäŋa). Several other Dhuwa moiety clans own small
parcels of land/water (riŋgitj) in this area and this is represented by the squared design, but the design itself belongs to Djapu
people.

The dhaŋgi story is told in the sacred songs (manikay) of Djapu people and danced at ceremonies (buŋgul). When Yolŋu dance
galumay, they open and close their arms as though opening and closing these fishing nets. Waṉḏawuy is also associated with the Thunderman, Bol’ŋu. In ancestral times, Bol'ŋu travelled from Wessel Islands south through various Dhuwa moiety clans' country. He was both man and cloud, the heavy cloud (wolma) which brings the first rains of the wet season. He travelled in the clouds, and rain fell when he urinated.

As Bol'ŋu travelled through the country, the Dhuwa clouds and the rain followed him. Rivers and creeks and springs with
freshwater for the dry season formed. And he said to himself, let it be like this always. As he passed by Bol'ŋu named the
rivers and springs at the sites he visited. He named trees and antbeds, and these are still the names for all these things at
these places.

In each clans' country Bol'ŋu gave ceremony and law to the people. He taught songs and dances and the designs that belong to
each of the clans, and he taught initiation ceremony to make the young boys men. The song cycle describing his travels is sung
at these ceremonies.

The Dhuwa clans that sing Bol’ŋu all have a special piece of rainforest belonging to Bol’ŋu. From this rainforest small thunder
clouds rise from each territory. They also belong to Bol’ŋu. He has brought them all together. The curved lines are
representative of his spear but also the clouds from the territory of the following clans; Rirratjingu; Ḏäṯiwuy; Ŋaymil; Djapu;
Djambarrpuynŋu; Bararrŋu and Dhuḏi-Djapu.
