The traditional arc of the sports story is emphasised by references to some of the worst aspects of Roman slavery in flashbacks to Nubia's background, followed by the best outcome of slavery for a Roman, as Sisyphus is suddenly freed with the final victory. This makes the story about so much more than which set of horses wins a race and effectively uses the Romans' slave trade to enhance the sports story, while also maintaining a sense of the horrors of the world outside the Circus.
