Womardu , Long Neck Turtle - Yolngy Tribe Art

This ochre painting has a story, en verso, as told by the artist: It shares teaching that has been passed on through many generations. It talks about the art of catching Womardu, a long-neck turtle, and the importance of sharing the food with all members of their tribe. Their simple traditions of daily living, dream life, and the deep respect for the wisdom of age.

It came from Oenpelli; Gunbalanya (also spelled Kunbarlanja, and historically referred to as Oenpelli) is an Aboriginal Australian town in west Arnhem Land in the Northern Territory of Australia, about 300 kilometers (190 mi) east of Darwin. The main language spoken in the community is Kunwinjku (aka Bininj Gun-Wok). At the 2016 Australian census, Gunbalanya had a population of 1,116. Western Arnhem Land.

Artists have been painting with ochre, a naturally occurring pigment, for hundreds of thousands of years. Their masterpieces range from prehistoric, ochre-pigmented images on cave walls to paintings on canvasses and other artwork from medieval times and onward.

Ochre (pronounced OAK-er) is clay pigmented by hematite, a reddish mineral that contains oxidized iron, which is iron that's been mixed with oxygen, said Paul Pettitt, a professor of paleolithic archaeology at Durham University in the United Kingdom.

Because ochre is a mineral, it doesn't wash away or decays, allowing it to persist through the ages. "Its vibrant color and ability to adhere to surfaces — including the human body — make it an ideal crayon or paint base," said April Nowell, a paleolithic archaeologist and professor, and chair at the Department of Anthropology at the University of Victoria in Canada.
