Social Structure of Ancient Japan!

Bush Tucker Story- Mick Namari Tjapaltjarri

Aboriginal art is a highly distinctive environmental art form associated with the spiritual beliefs of the native people of Australia. Traditionally, Aboriginal art includes rock paintings, dot paintings and bark paintings. Often, aboriginal designs illustrate the “Dreamings” that underpin Aboriginal spiritual and cultural life. Visual Art is only one of the ways of expressing Aboriginal dreaming. It can be expressed by dance, music, story and craft. Aboriginal art comes out of their culture and beliefs. In the artwork (Bush Tucker Story) by Mick Namari Tjapaltjarri, there are a variety of lines and dots that join together to create the swirling design. The semi-circle like figure represents rainbows, clouds and cliffs. On the far right hand side of the artwork there are lines that represent fire, smoke, water and blood. It represents the power of water for the growth of plants, running water over the ground and the sight of rainbows after the rain.
