The FLAME (Framing the Late Antique and early Medieval Economy) project involves an international group of scholars investigating the process of change in the economy of the Mediterranean and surrounding regions during the transitional period from antiquity to the early Middle Ages in the Byzantine, Islamic and European spheres and while using coinage as a proxy. It is a project of the Princeton University Numismatic Collection. This website includes several of FLAME’s outputs, including its digital applications, bibliography. The data underlying the project is continuously being vetted and cleaned.


To produce comprehensive date on coinage in the period of the transition from the ancient to the medieval world comparable and complementary to that which Chris Wickham assembled for Framing the Early Middle Ages primarily based on documentary and archaeological evidence. We intend to work through the technical numismatic issues and to present our results in a form that will be of value to historians and others not trained in numismatics.

FLAME’s Research Phases

  • I – Minting, 325-c.725 CE – basically a review of the all coins produced at Roman and Sassanian mints, with note of issues of denominations and (less completely) types produced.
  • II – Circulation, 325-725 CE – based on literary sources for the relationship between coin issues and moneys of account, and hoards and site finds for evidence of the geography and chronology of circulation.

The minting video is currently on YouTube and can be freely used.
