Roy Wiggan, a senior leader of the Bardi people, is the only one authorized to create "ilmas" - painted plywood panels combined with wool weavings worn by dancers during religious ceremonies that recount the deeds of the Great Ancestors in the Dreamtime. Their geometric shapes, of great variety (circles, stars, crosses, arcs), result from highly elaborate combinations that seem to materialize traditional ground painting patterns in space - a sort of Aboriginal "mantras" transformed here into true sculptures.

This ilma symbolizes a fish trap, with the four semicircles representing the water basins where it is placed.

This canvas comes with certificates of authenticity from the Sunday Island art center (W.A. No. SO/235-2) and the Arts d’Australie • Stéphane Jacob gallery, an expert in Aboriginal art.
