Author's abstract: Mudrooroo and Alexis Wright seem to have little in common. Mudrooroo belongs to the first generation of Australian Aboriginal writers and wrote many novels and critical studies as well as poetry. As for Alexis Wright, she wrote her first novel in 1997. Yet the landscapes they describe are charaterized by the same tension between a homogeneous surface and sub-layers that criss-cross, overlap and surface, thus posing a threat to the apparent unity of colonial space. This essay addresses the issue of palimpsestic landscapes and characters as clues to pinpoint the specificities of Aboriginal aesthetics. It also focuses on the use of intertextual references as a means to subvert colonial discourse.
