This beautiful book is ostensibly a conventional art monograph. In its innovative tweaking of the standard model, however, Centre of the Centre is one of the most rewarding publications about an Australian artist in recent years. Exploring two decades of ambitious work by Mel O’Callaghan, an Australian based in Paris, the book begins now, with her latest projects. In a quasi-geological enterprise, it then mines works whose interconnected seams comprise expansive video installations, sometimes including objects; wonderful paintings on glass; and, always, performed actions. Speaking about Parade (2014), Juliana Engberg noted the ‘ritualised, Sisyphean endeavour’ characterising O’Callaghan’s work.
