Oscar Moro Abadía & Martin Porr (ed.). 2021. Ontologies of rock art: images, relational approaches, and Indigenous knowledges. Abingdon: Routledge; 978-0-367-33780-3 hardback £120

This book has a Foreword, Introduction and 20 papers by 48 named contributors. There are 90 figures and one table. Despite being about 'Indigenous knowledges', only two of the papers have authors who identify as Indigenous. There are 18 authors from Australia, nine from the USA, six from Canada, and one from South Africa (all countries with significant Indigenous populations), six from England, three from France, two from Spain and one each from three other countries. Nowadays, how can a book that addresses 'Indigenous knowledges' and has majority contributions from three colonised countries have only two papers with Indigenous authors?
