For my modern cave painting I constructed a brush out of a beech tree branch and a chicken feather. To paint my image, I mixed soil that had a high concentration of red clay with vegetable oil. The oil helped to change the viscosity of the soil and made it easier to spread with the brush.
In our reading, I noticed that many of the theories about the functions of cave painting revolved around a religious or mystical use. I wanted to parallel this in my own modern cave paintings. The symbol that I painted on the stone surface is a mantra significant in many religions. I have found that the use of the symbol has brought a sense of calm and security to my life.
