in the frame of the European Research Council project CASTELLANY ACCOUNTS, "Record-keeping, fiscal reform, and the rise of institutional accountability in late-medieval Savoy: A source-oriented approach". Both the conference and the volume have received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No. 638436). I am indebted to my colleagues in the project CASTELLANY ACCOUNTS, Aude Wirth-Jaillard and Roberto Biolzi, for their assistance in organising the conference, and to John Sabapathy and Alessandro Silvestri for their useful suggestions.
