Aboriginal art
Australian Indigenous art is the oldest ongoing tradition of art in the world. The earliest artworks were rock carvings, body painting and ground designs, which date back more than 30,000 years.Symbols are used in aboriginal art, to show different things. While the meaning of these symbols is often shared, they can change meaning within the same piece, and they can be different between different groups.  Aboriginal art is a language in itself, communicating through beautiful patterns. This started around 30,000 to 40,000 years ago.
