This chapter examines the role of commodities and their movements to the complex processes of change and urbanization in the Greek world. It suggests that economies of urban centers emerged out of, and came to reside in, the consumption of goods driven by fashion, as many people in fluid political and social settings use goods to display their political aims and construct social ambitions. Thus, the increasing numbers of communities that might seriously be called urban by the sixth century could be considered, in the most literal sense, as consumer cities.
