Acknowledgments

Sections of this chapter have been presented to the Pybus Club (Newcastle, 1985), the Classical Association Triennial Meeting (Oxford, 1988), a conference organized by the Wellcome Institute for the History of Medicine (London, 1990), and the Liverpool Medical History Society/Society for the History of Science (Liverpool, 1991). I am grateful to all who made suggestions as to its improvement on these occasions, but above all to the careful and generous scholarship of Monica H. Green and Mark Micale.
