One of Patrick Whiteâs working notebooks, acquired by the National Library of Australia in 2006, is almost exclusively devoted to material related to his breakthrough novel Voss (1957), which marks a new departure in his career. It is a historical novel set in Australiaâs colonial period, though with thematic connections to Whiteâs earlier works. Close attention to Notebook 5 shows how extensively White researched its historical background and how he absorbed that research, sometimes transposing details verbatim into Voss. While certain material deals with Ludwig Leichhardt and his expeditions into the interior (for example Daniel Bunceâs Travels with Dr Leichhardt in Australia [1859] and Alec H. Chisholmâs Strange New World [1941]), it is apparent that White is more interested in details of Leichhardtâs various journeys than in debates about the man himself. He read other explorers, notably Edward John Eyre, and settlers of whom John Dunmore Lang is prominent, his notes revealing a particular interest in Aboriginal people. A second strand of Whiteâs research informs those sections of Voss set in Sydney in the 1840s, and a third involves theological and philosophical speculations about the nature of faith that are reflected in the musings of Laura Trevelyan and others. In addition, there are fragments of draft of both Voss and Riders in the Chariot (1961), indicating that White was already incubating the later novel as he was completing Voss. It appears too that he undertook major restructuring of Voss at a late stage.
