This article asks why women are ignored in debates about ancient economies and suggests a way forward. It argues that women performed a wide variety of diverse economic activities, though this is not particularly discernible from the scholarly literature, which mostly casts them as patrons or prostitutes and, despite the household being a basic economic unit to which women contributed, generally considers economic actors as male by default. However, by drawing on feminist economics, social history and gender studies, it is possible to reframe women’s varied activities in ways that acknowledge their labour, spotlight female agency, challenge the (gendered) categories of analysis and discourses that are predominantly used within ancient history, and recentre questions relating to the structures of inequality created by ancient economies. Three case studies explore some of the problems and raise new questions: Z3, a building in the Kerameikos the function of which is debated, the contribution of tax-farmers to sacrifices on Kos and the water supply in Athens. That is, this article argues that examining how ancient economies were gendered is a profitable way to think about both economic history and gender history.
