Yes it is Malouf's context - but remember that the context is not necessarily confined to the dates that you lived in - its also what went on before, ie. your historical context. so, Malouf's historical context is the history of Australia - how does his knowledge of colonisation affect his protrayal of Tomis, a village on the border of the mapped world? How does his knowledge of the Australian Aborigines affect his portrayal of the Getic tribes? How does his personal family history affect his knowledge of what it feels like to be an outsider? On top of these things, the markers are also looking to see that you understand the historical context of the work - ie. Ovid's context - who he was, what social conditions there were, what factors and beliefs would have shaped his attitude. You need to show that you understand these to be able to make the connection between Ovid's and Malouf's context. Yes, it is very important to remember to talk abhout Ovid as a ocnstruct of Malouf, not as a person, but it is equally important in an historical fiction to remember that there is a real historical context that can't be ignored.
