* I would like to thank Christopher Jones, Brent Shaw, and Noel Lenski, who offered valuable advice on an earlier draft of this paper. I am especially grateful to Boudewijn Sirks, who provided thoughtful and incisive comments; though he will not agree with some of the conclusions made here, his scholarly generosity has spared me from my worst errors and much improved this paper. I appreciate the friendly and efficient editorial work of the CQ team, particularly Rhiannon Ash, and the insightful advice of the anonymous reader. Above all I owe a debt of gratitude to Mike McCormick, in whose seminar this paper first took shape, for his continuous guidance. All errors and infelicities are purely my own.
