All over Australia there are sites where you can find wonderful examples of aboriginal rock art and prehistoric cave paintings in a range of styles.
One particularly interesting style is the cross-hatch or "X-ray" art found in the Arnhem Land and Kakadu region of the Northern Territory. These paintings from long ago, some as much as 40,000 years old, are representations not only of the indigenous creatures of the region, such as fish, turtles, and kangaroos but also of mythological creatures, the Mimi spirits, who are believed to be creation ancestors who taught the people all that they needed to know.
Another form of rock art is the "Bradshaws" in the Kimberley region of Western Australia. Again, many of these date back thousands of years. Known as "gwion gwion" by the natives, legend has it that birds created them using their own blood and feathers to draw the figures.
