Versions of this paper were presented at the University of Edinburgh's Classics Seminar Series, and at the Cambridge Philological Society; lively discussion ensued on both occasions, and I am grateful for the responses I received. I would also like to thank the journal's anonymous reviewers whose suggestions have lead to me clarify and improve the structure of this complex argument. Lastly, thanks are due to Ioannis Ziogas, as always, for his perceptive comments and unstinting encouragement.
