Aboriginal rock painting of Mimi spirits can be found dating back as far as 50,000 years ago in the Nourlangie Rock in Arnhem Land or Kakadu in the Northern Territory of Australia.
Mimis are fairy-like beings of Arnhem Land in the folklore of the Indigenous Australians of northern Australia. They are described as having extremely thin and elongated bodies, so thin as to be in danger in high winds. To avoid this, they usually spend most of their time living in rock crevices. They are said to have taught the Aborigines of Australia how to hunt and prepare meat.
The Mimi are tall, thin beings that live in the rocky ridges of northern Australia as spirits. Before the coming of Aboriginal people they had human forms.
When Aboriginal people first came to northern Australia, the Mimi taught them how to hunt and cook kangaroos and other animals. They bought to Man the knowledge of painting. They also did the first rock paintings through which taught Aboriginal people their painting skills.
The Mimis taught them to cook and showed man how to control fire. Fire is a purely physical need for warmth, a means of physical comfort, cooking and survival.
