Parts of this work have been presented to audiences in Cambridge, London, Oxford, and Paris. The reactions of the audiences on these occasions have been invaluable.

Parts of this book are based on work published elsewhere as parts of Warren Reference Warren2001a, Reference Warren2010, Reference Warren2011a, and Reference Warren and Leighforthcoming b. I thank the respective publishers and editors for their permission to reuse this material. Translations of ancient texts are my own except where a translator is named.

I would like to thank my colleagues in the Faculty of Classics at the University of Cambridge and Corpus Christi College for their encouragement and advice and for covering my teaching and administrative duties during my sabbatical leave for the academic year 2012–13, particularly the members of the B Caucus in the Faculty and Marina Frasca-Spada, Thomas Land, and Emma Wilson at Corpus Christi.

I also thank my family and, most of all, Sara Owen.
