ACKNOWLEDGEMENTS
I am indebted to the British Library for permission to quote from manuscripts in their Frazer collection and to Alan McCormick of the Castle Museum, Nottingham, for permission to reproduce his map of Nemi. Others to whom warm acknowledgements are due, either for general encouragement or for particular points of information, are Warwick Gould, Jeremy Maule, Roger Paulin, Ralph Pite, and Deirdre Toomey. Lastly, for putting up with the editor whilst engrossed in his fascinating task, no words are sufficient to convey his gratitude to his wife Catherine and his son Benjo.
