The COSA logo
and the legend of
the Marryalyan
The Marryalyan is the two-snake emblem of the Warramirri people who occupied a large group of islands in the Arafura Sea off the northern coast of Australia, now known as the Wessel Islands. Most Warramirri people now live on Elcho Island.
The Marryalyan was one of their major gods, possessed of infinite inventiveness. He lived under the sea and through the power of his breathing boiled up the vapour that makes the clouds, the weather and the storms. He invented living creatures, starting with minute particles in the sea, pinching them together to make different forms until he had filled the ocean.
