Chapter 3 of Earthopolis: A Biography of Our Urban Planet discusses the crucial role of cities in enabling small elite groups to amass large pools of wealth while guaranteeing poverty for the large majority of people whose labor made that wealth possible. This is the first of two chapters on the subject. It shows how state actors and wealthy elites controlled rural land and exploited wealth created by agricultural laborers and the energy of the Sun and Earth. It argues that building pre-modern cities and deriving wealth from them always involved the enslavement of millions of laborers for a wide diversity of tasks. Finally, it traces the origins and proliferation of urban artisans, shops, and marketplaces as well as the built hinterlands they required to create smaller pools of wealth in cities. This wealth served as cities’ economic lifeblood despite obstacles artisans and shopkeepers faced within their complex political relationship to urban states and wealthier elites.

The editors’ Introduction provides an overview of and rationale for the volume as a whole. It highlights the book’s key contributions and conceptual frameworks, in part by offering two brief case studies – or “snapshots” – of the dynamic interplay of music and memory in different times, places, and media: Etruscan tomb painting and Athenian comedy.
