Bark paintings have a long cultural tradition, believed to extend back many thousands of years. In northern Australia, the walls of bark shelters in the Kimberley and Arnhem Land may well have been painted to convey and illustrate stories in the same way that rock shelters were. Bark painters in the Maningrida region invoke customary practices and experiment with visual forms. Their paintings merge the natural and spiritual worlds, the secular and sacred, and embody and evoke ancestral presence.The subject matter of some works on bark express or focus on djang, the power of country itself; others the ancestral activities that created it or inhabit it: the powerful Rainbow Serpent Ngalyod, female water spirits including Yawkyawk and jin-Merdewa, and spirit beings such as Namorrorddo and Wangarra. Some paintings feature geometric designs inspired by body painting. Spirit figures such as the long thin Mimih spirits said to live in the rock country are also frequently depicted, as are animals hunted as game, including kangaroo and barramundi.
The process of making a bark painting begins with the artist choosing a suitable tree (stringybark gum tree, Eucalyptus tetrodonta), in the wet season when the sap is rising and the bark is fairly supple and easy to grip. After finding a section of bark that is free of knots and termite damage, cuts are made top and bottom and, after some encouragement by tugging and prying, a hollow open cylinder of bark is removed. The rough outer bark is stripped off and the bark sheet is trimmed and placed over a fire, inner side downwards, to drive out moisture, including the sap. The bark sheet, pliable from its steaming session, is next placed on the ground and trodden on to flatten it out. Heavy weights are placed on it as it cools to ensure that it doesn’t curl or warp.
Artists use a rich palette of colours derived from natural pigments that can be sourced from their clan estates. The reds, purples, pinks and yellows come from ochres (forms of iron oxide or limonite). Black generally comes from charcoal, and white is from pipeclay. All of these earth pigments are strongly associated with djang. The pipeclay used to create the brilliant white paint, for example, is said to be the faeces of the powerful Rainbow Serpent (Ngalyod in the Kuninjku language) and the spirit essence of the Mardayin ceremony.
Sometimes natural fixatives are mixed in to bind the pigments: wax, yolk of eggs, resins and the sap of orchid plants. Today PVA glue is more commonly used as a binding agent for the pigments. The tool that an artist uses to apply colour to the bark depends on the style of painting and available resources. It may be a feather, or a brush made from a few strands of straight human hair. Cyperus javanicus, a tough sedge grass, may be used to make the slim reed brush required to execute the fine rarrk designs.
