The title of Erdkamp's new book fails to do it justice. This study looks at much more than the grain market. Indeed, the first three chapters are a wide-ranging discussion of-and excellent introduction to-Roman agriculture. They also examine the cultivation of olives and grapes, and the economic strategies of peasants, as well as those whose production was geared more toward the market. In order to understand the grain market, Erdkamp looks far beyond the marketplace to the constraints placed upon producers, the problems of storage and transportation, and the impacts of taxation, geography, and public food distribution on supply and demand.
