This chapter considers the impact of Greek on Latin Literature. Unlike the expectations of modern post-colonial theory, the imperial Romans were captured by Greek culture. Latin literature’s relation to Greek becomes a key moment in the cultural self-definition of Rome. This cultural history is explored first through Cato the Elder as a figure who publicly was scornful of the impact of Greek culture on Rome, and who became thus for later Romans an icon of conservative opposition to cultural change. The chapter then considers how much Latin Greek writers might be presumed to know and, conversely, how Romans explicitly paraded their adaption and adaption of Greek material and Greek language in their writings. Third, the chapter considers the politics of code-switching between Greek and Latin. Fourth, the chapter looks at how this cultural conflict becomes a matter of Christian ideology as part of a politics of translation between Hebrew, Greek and Latin: what changes when God’s word is transformed between languages? Finally, the chapter asks what is known by Latin literature that Greek does not know (and vice versa)? What boundaries should we place between Greek and Latin literature?
