Rock art reveals Aboriginal response to colonial upheaval through monumental ancestral imagery
A study published in Australian Archaeology documents that Aboriginal artists in Arnhem Land created oversized paintings of ancestral beings, including a 6-meter Rainbow Serpent, during the 19th and 20th centuries. Researchers recorded 165 rock art sites with senior Traditional Owner Charlie Mungulda, focusing on post-contact art that depicted figures at unusually large scales. The authors suggest these monumental works were a deliberate effort to assert control over land and traditions amid the disruptions of European colonization.
The research team documented 165 rock art sites in the Awunbarna region since 2018, working alongside senior Amurdak Traditional Owner Charlie Mungulda. Their survey recorded 29 Rainbow Serpent images across 21 locations, representing the densest concentration of these ancestral beings found anywhere. Beyond the serpents, they catalogued a giant human figure exceeding 2 meters and the only known depiction of a baleen whale in Australian rock art.
Dating these works relies on layering patterns and pigment analysis, since white pipe clay fades within a few centuries. The team also identified a 124-meter stone arrangement resembling a Rainbow Serpent, suggesting monumental expression extended beyond painted surfaces into landscape-scale constructions.
This research could reshape public understanding of Indigenous responses to colonization, presenting Aboriginal communities as active agents rather than passive victims of historical change. The findings may influence how museums and heritage organizations interpret post-contact art, potentially affecting land rights discussions and cultural heritage protection policies. For descendant communities, the study offers validation of ancestral resilience, while for archaeologists it demonstrates how art functioned as a tool of cultural assertion during periods of upheaval.
