The new paradigm of ancient economic history that has dominated the last twenty years is based on New Institutional Economics; its key concepts are growth and transaction costs. It has succeeded in proving that the ancient economies were not static and in documenting the significance of ancient markets; but by excising labour, slavery, and exploitation from discussion, the conceptual limits of this paradigm are becoming apparent to more and more people. The volume edited by John Weisweiler on debt in the ancient Mediterranean and Near East is solid evidence that an alternative, non-neoliberal, paradigm is currently in the process of formation.1 The book is obviously an attempt to assess the validity of David Graeber's blockbuster book on debt for the study of ancient economic and social history.2 As with the volume on citizenship presented below, the fact that this collection of twelve essays ranges temporally from the archaic period to the early middle ages and includes Greek, Roman, and Near Eastern societies is an excellent illustration of a growing and encouraging trend in our discipline. This is a highly stimulating volume. The essays explore: the nexus between coinage, slavery, and warfare in various ancient societies; how quantified social obligations colonized various social, political, and intellectual fields; and whether Graeber's concept of the Axial Age is valuable for the study of ancient history. Perhaps unsurprisingly, Graeber's model seems to fit best the world of ancient empires (Roman, late Roman, and Sassanian), but seems to make less sense for the world of Greek poleis. This illustrates, yet again, the need for Greek historians to think seriously about the peculiarities of the Greek world and the appropriate comparisons.
