For example, we know from the Dynamic paintings that over 8,000 years ago, Aborigines would have rarely eaten fish and sea levels were much lower at this time. In fact, fish didn't start to appear in paintings until the Yam period along with shells and other marine images. The paintings of the Yam tradition also suggest that, during this time, the Aborigines moved away from animals as their main food source and began including vegetables in their diet, as these feature prominently. Freshwater creatures didn't appear in the paintings until the Modern period from 4,000 years ago. So, these paintings have already taught us a lot. But one image that has always intrigued us is known as the "Rainbow Serpent". The Rainbow Serpent, which is the focus of my most recent project, gets its name from its snake or serpent-like body and it first appeared in the Yam period four to 6,000 years ago. Many believe it is a curious mixture of kangaroo, snake and crocodile. But we decided to study the Rainbow Serpent paintings to see if we could locate the animal that the very first painters based their image on.
