Chapter I is a much-expanded version of an essay that appeared in Arion (third series, vol. 9, 2001, pp. 63–89). The third section of Chapter 3 reuses parts of 'Green Politics: The Eclogues' from The Cambridge Companion to Virgil, edited by the author, Cambridge University Press, 1997, pp. 107–24. I am grateful to the publishers for their permission to reuse this material.
